Background An increase in training intensity could create changes in psychological and physiological variables in competitive athletes. For this reason, it is very relevant to know how an intensive training block could influence psychological variables in competitive swimmers. This study examined the effect of an intensive training block (HIT) for 2 weeks on the anxiety state and swimming performance compared to standard aerobic training. Methods Twenty-two male competition swimmers were randomly assigned to two groups: HIT group (n = 11; age = 16.5 ± 0.29 years) and control group following the standard training program (n = 11; age = 16.1 ± 0.33 years). Psychological status variables (cognitive anxiety, somatic anxiety and self-confidence) and swimming performance (100-m front crawl) were measured pre-and post-test. Results A significant effect of time was found for all psychological variables and swimming performance (F ≥ 17.6; p < 0.001; d ≥ 0.97). Furthermore, a significant group × time interaction effect was found in cognitive (F = 14.9; p < 0.001; d = 0.62) and somatic anxiety (F = 5.37; p = 0.031; d = 0.55) were found. Only a significant group effect was found in somatic anxiety (F = 27.1; p < 0.001; d = 1.2). Post hoc comparison revealed that both groups increased their cognitive anxiety and swimming performance, and decreased their self-confidence from pre to post test. However, cognitive anxiety increase significantly more in the HIT group compared to the control group. Furthermore, only the HIT training group significantly increased somatic anxiety over time, while somatic anxiety did not change significantly over time in the control group. Conclusion Our findings indicated that a sudden increase in training intensity increased state anxiety more than standard training, but both conditions similarly enhanced swimming performance. Although the current level of psychological state is not affecting swimming performance negatively over this period, it should be regularly monitored by psychologists as it over a longer training period perhaps could have a negative influence on swimming performance.

Background: Professional engagement is a complex process and likely varies depending on the individual's personality and characteristics such as years of experience. There are conflicting results regarding the effect of professional engagement and its impact on work performance among physical education teachers and interns. Our study aims to examine the relationship between work engagement among physical education teachers and interns. Objectives: In this study, we compared work engagement between interns and physical education teachers. Methods: Two hundred fifty individuals (130 young interns, 120 qualified teachers) participated in this study. The teachers were classified based on their years of experience (1-2 years and 2-5 years). All participants completed the questionnaire translated and adapted by Loadhal and Kejner (1965), readapted by Alem, Bujold, et Bertrand, 2003 to evaluate the parameters of engagement. Results: Interns had significantly higher values in all dimensions of work engagement overall (all P < 0.001). Interns are more involved and motivated in their work, leading to better professional engagement overall. Comparison based on years of experience revealed that as the number of years increases, work engagement decreases among physical education teachers. Conclusions: Based on the results from our current study, we conclude that teacher's professional commitment decreases over time.

The aim of this study was to study the effect of setting a personal goal to achieve on psychological parameters (cognitive anxiety, somatic anxiety and self-confidence) and on the chronometric performance of 50m butterfly in young swimmers. aged between 12 and 13 years old during the 2019/2020 sports season. The population was divided into three groups, the first group1 (G1) underwent competition preparation without a set goal (method1), the second group2 (G2) was oriented towards a vague goal “Do your best” (method2) , whereas, the third group was asked to respond to a difficult-to-achieve goal according to a goal-setting interval (GBI) (method3). The results indicate that method 1 and method 3 increased the level of cognitive and somatic anxiety in swimmers in these two groups (p < 0.05). Furthermore, the self-confidence score was low in group 1 compared to the other two groups. Our results also show that chronometric performance was improved (p < 0.05) better by method 3 than by method 2, while performance remained unchanged in group 1. The difficult goal setting by IFB improved the chronometric performance, but at the same time increased the values of cognitive and somatic anxiety, for this reason the mental trainers and the technical staff were invited to develop associated mental preparation models to this method of goal setting to help swimmers psychologically.

Tapering is a concept that is of great importance in relation to performance, due of its great effect on the psychological and physical condition of the swimmer. Therefore, the present study aims to investigate the effect of two-week of tapering characterized by a progressive training volume reduction on mood state and swimming performance in competitive swimmers. Twenty-four competitive male swimmers were randomly assigned into two groups. Experimental group (age = 16.9 ± 0.5 years) and control group (16.1 ± 0.4 years). The mood subscales (tension, depression, anger, fatigue, confusion and vigor), total mood disturbance and swimming performance (50-m front crawl) were measured in pre and posttest. Our findings revealed a significant improvement in mood subscales (20.8 to 47.8%), total mood disturbance (14.4%) and in swimming performance (3.5%) after 2 weeks of tapering training. A significant correlation was observed between the total mood disturbance and the 50 m front crawl (r = −0.63) only in the experimental group. It was concluded that a progressive reduction in training volume with a maintain of intensity could improve mood state and swimming performance. In addition, a change in total mood disturbance could affect swimming performance. Swimming coaches are advised to include tapering period according to the standards we mentioned earlier before competitive swimming to improve mental state, which helps the swimmers to overcome the negative influences of overtraining and therefore they can promote sprint-swimming performance.

Background: Self-esteem is considered a multidimensional strategy for coping with various complex situations. There are conflicting results regarding the effect of years of experience on dimensions of self-esteem among physical education teachers and trainees. Our study aims to examine the relationship between overall self-esteem in physical education teachers and trainees, and seniority at work. Objectives: In this study, we compared self-esteem between trainees and physical education teachers. Methods: Two hundred sixty individuals (140 young trainees, 120 qualified teachers) participated in this study. They were classified according to their years of experience (1-2 years and 2-5 years). All participants completed Rosenberg's global self-esteem questionnaire to assess parameters of self-esteem. Results: Physical education teachers had significantly higher values in all dimensions of global self-esteem (GSE) (all, P < 0.001). The comparison between years of experience revealed that as the number of years increases, overall self-esteem (GSE) also increases among physical education teachers. Conclusions: Based on the results from the current study, we conclude that seniority can be considered a key factor in developing levels of self-esteem among physical education teachers and contributes to a better perception of parameters related to global self-esteem (GSE).

Abstract Background This study aimed to compare various factors, namely perceived enjoyment (PE), percentage of peak heart rate (%HRpeak), blood lactate (La), rating of perceived exertion (RPE), and technical-tactical performance among soccer players across different bout durations (CB: continuous bout, MIB: medium intermittent bouts, and SIB: short intermittent bouts) and between male and female players during four-a-side (4vs4) small-sided games (SSGs) including goalkeepers. Methods sixteen female soccer players (age: 20.1 ± 0.5 years old) and sixteen professional male adults (age: 20.7 ± 0.7 years old) participated in the study. SSGs (4vs4) were performed in a CB: (1 × 12 min), and in an interval format: MIB: (2 × 6 min), and SIB: (3 × 4 min) with 2 min of passive recovery. PE was collected after each SSGs. The players’ heart rate (HR) was continuously measured, whereas ratings of perceived exertion (RPE) and, blood lactate concentration ([La]) were determined at the end of each SSGs. Technical-tactical performance were analyzed during each session of SSGs. Pitch dimensions were (length x width) (25 × 32 m), and relative space per players was 100 m2. Results For female soccer players, medium intermittent bouts (MIB) elicited significantly higher perceived enjoyment (PE) compared to continuous bouts (CB) (p < 0.001) and short intermittent bouts (SIB) (p < 0.01). Conversely, for male soccer players, CB resulted in higher PE compared to MIB (p < 0.001) and SIB (p < 0.001). During CB and MIB, peak heart rate (PeakHR) and percentage of peak heart rate (%HRpeak) were significantly higher in female players compared to SIB (PeakHR: CB: p < 0.001; PeakHR: MIB: p < 0.01; %HRpeak: CB: p < 0.001; %HRpeak: MIB: p < 0.01). Blood lactate (La) and rating of perceived exertion (RPE) were significantly greater in CB compared to MIB (La: p < 0.001; RPE: p < 0.01) and SIB (La: p < 0.001; RPE: p < 0.001) for female players only. For male players, CB resulted in significantly higher PeakHR, %HRpeak, La, and RPE compared to MIB (peak HR: p < 0.01, dunb = 1.35; %HR: p < 0.01; La: p < 0.01; RPE: p < 0.01) and SIB (peak HR: p < 0,01; %HR: p < 0.01; RPE: md = 0.87, p < 0.05). Regarding technical-tactical performance, in female players, the % of successful passes, successful tackles, and successful duels were higher during SIB compared to CB (p < 0.01; p < 0.001; p < 0.001) and MIB compared to CB (p < 0.01; p < 0.001; p < 0.001), while ball loss was lower during SIB compared to CB (p < 0.001) and MIB compared to CB (p < 0.001). In male players, % of successful passes and tackles were higher during CB compared to MIB (p < 0.001 and p < 0.05) and SIB (p < 0.001 and p < 0.05), while CB had a lower % of ball loss compared to MIB (p < 0.01) and SIB (p < 0.001). There was no significant difference in the % of successful duels between the bouts for either gender. Conclusion This study showed a difference in physical enjoyment between male and female soccer players depending on the bout duration of SSGs. For that, trainers should consider intermittent bouts for female soccer players and continuous bouts for male soccer players when designing SSGs-based training in order to significantly improve PE, training load, and technical-tactical performance.

The purpose of this study was to determine the effects of a reduced rim diameter (diameter 0.30 m) upon the kinematics of basketball free-throws. Ten male basketball players (mean ± s; age 17.1 ± 0.4 years, height 1.85 ± 1.43 m, mass 79.0 ± 5.3 kg) performed 8 direct successful free throws; 4 when using a standard 0.45 m diameter rim, and 4 with an 0.3 m diameter rim. Ball release parameters and joint angles at ball release were determined for each participant. The smaller rim was associated with significant increases (p < 0.0001) in ball release angle, ball release velocity, ball release height and shoulder joint angle at release. The reduced diameter rim can be advocated as a tactic for developing a higher ball release angle when training the shooting technique of young basketball players; this is likely to maximize the probability of a successful free-throw when attempted into a standard rim.

The study aimed to identify the role of sports in achieving the sustainable development of women in the Palestinian society, and to identify the level of knowledge of the study sample of the concept of sustainable development. Two areas, and the study population included all workers in some Palestinian institutions in the northern governorates of Palestine. The study sample consisted of (2040) respondents. The sample studied for the role of sport in achieving sustainable development for women also came to a moderate degree, with an arithmetic mean (3.22). The study recommended the need to promote the concept of sustainable development within the Palestinian educational curricula and sports circles, and to strengthen the sports strategies of Palestinian institutions for the important role of sport in achieving sustainable development.

Combined interventions of pool-based and dry-land workouts are a common practice in swimming training. However, the effects on strength, technique and swimming performance are still not clear. Through a randomized controlled trial study, we investigated the effect of combining high intensity interval training (HIIT) and maximum strength training (MST) on strength, technique and 100-m butterfly swimming performance. Competitive age-group swimmers (N = 22, males) were randomly divided into two groups. The experimental group (EG: 14.1 ± 0.3 years old) performed 8 weeks of combined short-moderate HIIT and MST. The control group (CG: 14.5 ± 0.3 years old) subjects performed their usual training. Muscular strength, technique and swimming performance were evaluated before and after 8 weeks. Substantial improvements were observed in maximum muscle strength (mean diff: 22–28%; p < 0.001; d = 3.25–3.61), technique (p < 0.05; d = 0.98–1.96) and 100-m butterfly swimming performance (3.5%; p = 0.001; d = 1.81) when combining HIIT and MST during 8 weeks. Combining short-moderate HIIT and MST during 8 weeks can enhance maximum muscular strength, technique, and 100-m butterfly swimming performance. Coaches should adjust training programmes accordingly since it could yield important differences in swimming performance during competitions.

The study aimed to identify the evaluation of the administrative performance of sports clubs from the point of view of the General Authority for Youth and Sports Libya, and to identify the level of knowledge of the study sample evaluation criteria in the areas of administrative performance of sports clubs in Libya, and the study population included two functional categories, namely senior management, middle management and sports offices in the regions of the employees of the General Authority for Youth and Sports previously Ministry of Sports currently, the study sample consisted of (79 ) people. The studied sample of the role of evaluating the administrative performance of sports clubs from the point of view of the General Authority for Youth and Sports came with a moderate degree with an arithmetic average of (3.28). The study recommended the work of time programs to monitor the performance of work within the corridors of the club in all financial, administrative and technical fields, lectures and workshops in all parts of Libya in order to introduce the evaluation and its importance.

Our Study aims were to test the impact of swimming practice on the development of postural stability among Tunisian Athletes. The analyses deal with the impact of the practice of swimming on the postural balance. They clarify the various constraints that influence the control mechanisms involved in maintaining the balance in the resort standing. Our study addresses 20 same age category male subjects (senior) returned in: an experimental group (10 swimmers, belonging to the Tunisian national team) and a control (no sports group 10). For this study we used the Neurocom version 8.0.2 system: scale Master® consisting of a flat form of force connected to a string of data to measure the speed of oscillation of the center of pressure in strong support bipedal, eyes open on ground. The results obtained showed no direct effect of the swimming practice on postural stability of Tunisian athletes. In fact swimming poses the need to evolve in an environment different from that in which any subject has built his balance, his motor skills of every day, the latter two are insured through the muscles; so balance follows the permanent integration of information transmitted by three receiving systems: Visual, proprioceptive and vestibular.

One of the important factors that improve soccer player's ability to engage more in the physical activity is verbal encouragement from the coach during exercise. The purpose of the study was to investigate the effect of the coach's verbal encouragement in football small-sided games on psycho-physiological parameters. Fourteen male students, soccer specialty, completed four sessions of small-sided games (SSG). Two sessions (S1 and S3) conducted with verbal encouragement (SSGE), and the other two sessions (S2 and S4) without VE (SSGN). Mood state was recorded before and after each training session using the profile of mood-state (POMS). Rating of perceived exertion (RPE) was measured after each training session. Heart rate was continuously recorded. Total mood disturbance decreases significantly in sessions with SSGE (S1: P < 0.05; S3: P < 0.001). RPE scores in sessions S1 and S4 (SSGE) have significantly higher (P = 0.035; P = 0.02) compared to session S2 (SSGN).In contrast, no significant differences between the two conditions were found for maximal heart rate during SSG. Teacher’s verbal encouragement is a beneficial method of increasing motivation, thereby improving the physical engagement of students in small-scale football matches. Uno de los factores importantes que mejoran la capacidad de los jugadores de fútbol para participar más en la actividad física es el estímulo verbal del entrenador durante el ejercicio. El propósito del estudio fue investigar el efecto del estímulo verbal del entrenador en los partidos de fútbol en espacios reducidos sobre los parámetros psicofisiológicos. Catorce alumnos varones, especialidad fútbol, completaron cuatro sesiones de juegos reducidos (SSG). Dos sesiones (S1 y S3) realizadas con estímulo verbal (SSGE), y las otras dos sesiones (S2 y S4) sin VE (SSGN). El estado de ánimo se registró antes y después de cada sesión de entrenamiento utilizando el perfil de estado de ánimo (POMS). La calificación del esfuerzo percibido (RPE) se midió después de cada sesión de entrenamiento. La frecuencia cardíaca se registró continuamente. La alteración del estado de ánimo total disminuye significativamente en las sesiones con SSGE (S1: P < 0,05; S3: P < 0,001). Las puntuaciones de RPE en las sesiones S1 y S4 (SSGE) son significativamente más altas (P = 0,035; P = 0,02) en comparación con la sesión S2 (SSGN). Por el contrario, no se encontraron diferencias significativas entre las dos condiciones para la frecuencia cardíaca máxima durante la SSG. El estímulo verbal del maestro es un método beneficioso para aumentar la motivación, mejorando así la participación física de los estudiantes en los partidos de fútbol a pequeña escala. Um dos fatores importantes que melhoram a capacidade do jogador de futebol de se engajar mais na atividade física é o incentivo verbal do treinador durante o exercício. O objetivo do estudo foi investigar o efeito do encorajamento verbal do treinador em jogos reduzidos de futebol em parâmetros psicofisiológicos. Quatorze estudantes do sexo masculino, especialidade de futebol, completaram quatro sessões de jogos reduzidos (SSG). Duas sessões (S1 e S3) realizadas com estímulo verbal (SSGE), e as outras duas sessões (S2 e S4) sem EV (SSGN). O estado de humor foi registrado antes e após cada sessão de treinamento usando o perfil de estado de humor (POMS). A avaliação do esforço percebido (PSE) foi medida após cada sessão de treinamento. A frequência cardíaca foi registrada continuamente. A perturbação total do humor diminui significativamente nas sessões com SSGE (S1: P < 0,05; S3: P < 0,001). Os escores de PSE nas sessões S1 e S4 (SSGE) foram significativamente maiores (P = 0,035; P = 0,02) em comparação com a sessão S2 (SSGN). Em contraste, não foram encontradas diferenças significativas entre as duas condições para a frequência cardíaca máxima durante a SSG. O encorajamento verbal do professor é um método benéfico para aumentar a motivação, melhorando assim o envolvimento físico dos alunos em partidas de futebol de pequena escala.

: This study aimed to examine the effects of verbal encouragements (VE) on linear sprint speed, jump height, change of direction (CoD) speed, and subjective perception of effort among high school students. Twenty-three high school male students volunteered to participate in this study (age = 19.70 ± 1.06 years). Participants were evaluated during two separate sessions (first session with VE and second session without VE) in a randomized order. The teacher provided VE during each physical test. Jump height [squat jump (SJ), countermovement jump (CMJ), five jump test (FJT)], linear sprint speed (10-m and 30-m sprint), and CoD speed (30-m with CoD) were performed during the two sessions. The rating of perceived exertion (RPE) was recorded after each session. Results indicated that VE induced moderate but sig-nificant improvement in 10-m (ES = 0.71, P = 0.023) and 30-m (ES = 0.76, P = 0.016) sprint speed. However, the 30-m sprint with CoD did not change across conditions (P > 0.05). For jump tests, significant moderate-to-large increases were observed under the VE compared with the non-VE condition (ES = 0.65 to 0.90; P = 0.005 to 0.037). Findings showed a large increase in effort perception following VE compared to the non-VE condition (ES = 1.54, P < 0.001). In conclusion, the findings of this study indicated that VE has a positive impact on measures of physical fitness but increases effort perception.

The present study investigated the effect of 9 weeks of combined resistance training (aquatic and dry land resistance) on maximum lower body strength, leg kick, and swimming performance in competitive swimmers. Twenty-two male national competitive swimmers were randomly assigned into two groups: experimental group (EG: age = 16.2 ± 0.3 years) or control group (CG: age = 16.3 ± 0.3 years). The EG performed a combined resistance training while the CG group completed their usual training. One repetition maximum (1RM) back squat, 30 m leg kick, and swimming performance (100 m front crawl, start and turn) were evaluated in pre and post test. The findings showed a significant increase in 1RM back squat (d = 1.90; 14.94 ± 1.32%) after 9 weeks of combined resistance training. In addition, ours results revealed a significant improvement in 30 m leg kick swimming (d = 2.11; 5.84 ± 0.16%) and in all swimming, start and turn performances (d = 1.83 to 2.77; 2.69 ± 0.18% to 15.14 ± 1.06%) in EG. All dependent variables remained unchanged in the CG. To sum up, 9 weeks of combined resistance training can improve the maximum lower body strength and leg kick swimming performance. These improvements can be the essential factors that subsequently positively affected swimming, start and turn performances. Combined resistance training is an effective training that can be incorporated by coaches and swimmers into their programs to improve strength, leg kick swimming, and, subsequently, swimming performance in competitive swimmers.

The aim of this study was to examine the effects of a multicomponent exercise training program on motor function and biochemical markers in patients with Alzheimer’s-type dementia. Twenty patients with Alzheimer disease, divided into the intervention group (IG; aged 84 ± 3.1 years) and the control group (CG; aged 86 ± 2.6 years) were included in this study. The intervention group was enrolled into an exercise training program for three months (two sessions of 60 min per week). The CG was instructed to follow their daily rhythm of life (e.g., rest, reading) without a physical training program. After 3 months of participation in a multicomponent exercise program, gait speed, balance and walking parameters were all improved in the intervention group as measured with the Berg Balance Scale, the Tinetti test, the 6-min walking test and the timed up and go test (p < 0.05 for all; percentage range of improvements: 3.17% to 53.40%), except the walking while talking test, and biochemical parameters were not affected (p > 0.05). Our results demonstrate that exercise improves postural control, aerobic capacity and mobility functions in patients with Alzheimer disease. Physical exercise is a safe and effective method for treating physical disorders in patients with Alzheimer’s disease and can easily be integrated in various programs for the management of Alzheimer disease.

This study aimed to examine the effect of four weeks of aquatic high-volume training (HVT) on the psychological state (somatic, cognitive anxiety, and self-confidence) and sprint swimming performance (50 m front crawl) compared to the standard training program (moderate volume training) in competitive swimmers. Twenty-eight male competitive swimmers participated in this study and were randomly allocated into two groups: HVT group (n = 14; age = 16.4 ± 0.31 years) and control group that underwent the standard training program (n = 14; age = 16.1 ± 0.30 years). All psychological state variables and swimming performance were measured in pre and post-test. Our findings showed a significant increase in anxiety state (34.13% to 45.83%; ES = 3.26 to 3.38) and a significant decrease in self-confidence (18.43%; ES = 2.39) after four weeks of HVT, while all psychological state variables remained unchanged in the control group (p > 0.05). In addition, our results showed no significant enhancement in swimming performance in both groups (p > 0.05). The sudden increase in training mileage negatively affected the anxiety, decreasing the state of self-confidence of the participants. In addition, four weeks of high training volume are insufficient to improve swimming performance. To conclude, gradually increasing the volume of the training load may be an adequate solution to promote adaptation to the effort, thus maintaining the stability of the psychological state of swimmers. In addition, it is recommended to integrate a concurrent mental preparation program with high-volume training to monitor the psychological state of competitive swimmers.

This study aimed to examine the effect of 9 weeks of concurrent resistance training (CRT) between resistance on dry land (bench press (BP) and medicine ball throw) and resistance in water (water parachute and hand paddles) on muscle strength, sprint swimming performance and kinematic variables compared by the usual training (standard in-water training). Twenty-two male competitive swimmers participated in this study and were randomly allocated to two groups. The CRT group (CRTG, age = 16.5 ± 0.30 years) performed a CRT program, and the control group (CG, age = 16.1 ± 0.32 years) completed their usual training. The independent variables were measured pre- and post-intervention. The findings showed that the one-repetition maximum bench press (1RM BP) was improved only after a CRT program (d = 2.18; +12.11 ± 1.79%). Moreover, all sprint swimming performances were optimized in the CRT group (d = 1.3 to 2.61; −4.22 ± 0.18% to −7.13 ± 0.23%). In addition, the findings revealed an increase in velocity and stroke rate (d = 1.67, d = 2.24; 9.36 ± 2.55%, 13.51 ± 4.22%, respectively) after the CRT program. The CRT program improved the muscle strength, which, in turn, improved the stroke rate, with no change in the stroke length. Then, the improved stroke rate increased the swimming velocity. Ultimately, a faster velocity leads to better swim performances.

This study aimed to compare the effectiveness of high, moderate, and low resistance training volume-load of maximum strength training on muscle strength and swimming performance in competitive swimmers. Thirty-three male swimmers were randomly allocated to high (age = 16.5 ± 0.30 years), moderate (age = 16.1 ± 0.32 years) and a low resistance training volume-load group (age = 15.9 ± 0.31). This study was carried out in mid-season (January to March). Pre and post strength (e.g., repetition maximum [1RM] leg extension and bench press tests), swimming (25, 50 m front-crawl), start (speed, time, distance) and turn (time of turn) performance tests were conducted. Our findings revealed a large main effect of time for 1RM bench press: d = 1.38; 1RM leg extension: d = 1.55, and for 25 (d = 1.12), and 50 m (d = 1.97) front-crawl, similarly for start and turn performance (d = 1.28–1.46). However, no significant Group × Time interactions were shown in all strength swimming performances, start and turn tests (p > 0.05). In conclusion, low training loads have been shown to elicit the same results as moderate, and high training loads protocol. Therefore, this study shows evidence that the addition of low training volume-loads as a regular part of a maximal strength training regime will elicit improvements in strength and swimming performance.

One repetition maximum (1RM) push-ups, based upon the load–velocity relationship, are able to predict the maximum upper body strength. The aim of the present study was to examine the relationship between the predicted 1RM push-up based upon the load–velocity relationship and swimming performance and kinematical variables in competitive swimmers. Thirty-three competitive male swimmers (age = 16.46 ± 0.59 years, body mass = 72.82 ± 8.41 kg, body height = 180.56 ± 5.69 cm) performed push-up exercises without a weight vest and with a 10, 20 and 30 kg weight vests. A load–velocity relationship was established as a product of the load and velocity of the push-up per participant, and the equation was used to establish a predicted 1RM. Our findings showed a predicted 1RM push-up of 82.98 ± 9.95 kg. Pearson correlations revealed a nearly perfect relationship between the 1RM push-up and the 25 or 50 m front crawl (r = −0.968, r = −0.955), and between 1RM push-up and the 25 or 50 m front crawl with arms (r = −0.955, r = x0.941). Similarly, our results revealed significant near-perfect correlations between 1RM push-up and kinematical variables (r = 0.93–0.96) except the stroke index, which had a large relationship (r = 0.56). This study suggests that swimming performance and kinematical variables are correlated with the predicted 1RM push-up. The 1RM push-up based upon the load–velocity relationship is a low cost and time-effective alternative for swimmers and coaches to predict maximum upper body strength to optimize swimming performance in short races.
