PURPOSE:To evaluate the efficacy of postmatch compensatory training (CT) in mitigating disparities in external speed load between nonstarters (with varying match exposure) and starters (>60 min match play without CT). METHODS:Forty-three professional soccer players (25 [4] y) were monitored across 68 matches using global positioning system. Players were classified as starters (G1, >60 min), nonstarters (G2, 0 min), and nonstarters (G3, 1-30 min). External load metrics included total distance, high-speed running (HSR), and sprint distance, analyzed as both absolute values and relative values (% of total distance covered, and per minutes played). CT consisted of high-intensity interval exercise (∼925 m). Generalized estimating equations with least significant difference post hoc tests were applied (P < .05). RESULTS:Significant group × intervention interactions were observed for HSR and sprint distance (P ≤ .002). Without CT, G1 showed higher HSR (585 vs 33-143 m) and sprint distance (115 vs 2-34 m) than G2 and G3 (P < .05). Following CT, both G2 and G3 markedly increased HSR (G2: 33→261 m; G3: 143→318 m; P ≤ .001), reducing differences versus G1. Sprint distance increased in G2 (2→75 m; P < .001), although G1 remained higher than G2 and G3 (P ≤ .05). Relative metrics confirmed these findings, with no between-group differences after CT. Total distance remained higher in G1 across conditions (P < .001). CONCLUSIONS:Postmatch CT effectively attenuates external speed-load disparities between nonstarters and starters in professional soccer players.

This study investigated longitudinal changes in strength- and power-related performance across an entire competitive season in elite soccer players using a frequent and systematic monitoring approach. Twenty-three professional players competing in the Brazilian first division were monitored over seven consecutive months. Athletes performed two to three resistance training (RT) sessions per week, with one weekly “control” session used to adjust training loads and assess neuromuscular status through bar-derived measures obtained in the half-squat exercise. Relative power (RP), relative strength (RS), and estimated one-repetition maximum (1RM) were recorded across 28 training sessions using the load associated with maximum power output. Weekly variations were analyzed using a 4-week rolling average, and pre-, mid-, and post-season periods were compared using repeated-measures ANOVA. Across the season, RP, RS, and 1RM exhibited a gradual and consistent positive trend. While only isolated meaningful changes were detected when individual sessions were compared with rolling averages, significant improvements were observed at the post-season time point compared with both pre- and mid-season values (p < 0.05). Notably, despite a modest ~5% increase from pre- to post-testing, absolute training loads did not change significantly across the season, indicating that performance gains were achieved without meaningful increases in training load magnitude. These findings demonstrate that a power-oriented RT model, supported by continuous monitoring and load adjustments, can effectively preserve and enhance strength and power throughout a competitive soccer season. This approach appears to mitigate commonly reported in-season declines in neuromuscular performance and offers a practical strategy for managing RT under congested competitive schedules.

It is recommended for athletes keep training to reduce the negative effects of detraining. This study aimed to verify the effects of a 15-week online training intervention during a pandemic quarantine in body composition and physical capacity of highly trained soccer players. Sixteen male under-20 soccer players were assessed after the first period of COVID-19 quarantine (March 2020 to September 2020; 170 days), and after the second period of COVID-19 quarantine (November 2020 to February 2021, 107 days). Body composition, vertical jump height, hamstring maximum strength and aerobic capacity were assessed. The online training program was performed during the second lockdown. In comparison with first pre assessments, results showed that fat mass (-0.95 +/- 1.27), free fat mass (1.22 +/- 1.19), squat jump height (5.36 +/- 1.99) and counter movement jump (3.19 +/- 3.77) were significantly improved (P < 0.05). However, there were no significant changes in total body mass, hamstring eccentric strength, and Yo-Yo IR1 after online training (P > 0.05). In summary, the findings of this study highlight the importance of carrying out a training program during a period of absence from traditional soccer training, in order to maintain the level of physical capacities of youth soccer players.

With a plethora of anthropometric and body composition measurements, may be challenging for soccer technical staff determining the most suitable protocol for their players.

This study investigated the associations between pre-season and in-season performance with external workload in professional soccer players. Twenty-one players completed hamstring strength, countermovement jump (CMJ), 20-m sprint, and Yo-Yo intermittent recovery tests before (pre-season) and after 8 weeks (in-season). External workload (total distance, high-intensity running distance, number of sprints, and power plays) was quantified during this period, and used to divide the average above and below subgroups outcome by outcome for further analyses. Significance was accepted when P <= 0.05. Hamstring strength declined from pre- to in-season [- 6%; p=0.014; effect size (ES): - 0.41], while Yo-Yo performance improved (46%; p=0.001; ES: 1.31). When divided by high-intensity running distance, only the below-average subgroup improved CMJ performance (5%; p=0.030). For minutes played, the above-average subgroup improved Yo-Yo performance (41%; p<0.001), but not the below-average subgroup. Furthermore, playing time correlated with improved Yo-Yo performance (p=0.040; r=0.534). Improved 20-m sprint performance associated with more sprints performed (p=0.045; r=- 0.453). Physical capabilities changed over a competitive season and were related to, and differentiated by, external workload. Because hamstring strength decreased and CMJ only improved in players exposed to less high-intensity external load, practitioners should individualize approaches to counteract these conditions when high external workload is performed over the season.

BACKGROUND:In soccer, the capacity for acceleration and high-speed tasks extends beyond linear sprints to encompass a broad spectrum of multidirectional movements, including curvilinear sprints. We aimed to correlate mandatory speed-related capabilities with curve sprint (CS) performance in male professional soccer players. METHODS:Twenty-one players (age 25.9 ± 5.4 years) performed the jump squat with 30% and 60% of body mass (JS30% and JS60%, respectively), countermovement (CMJ) and squat jumps (SJ), 10 m and 20 m linear sprint, 17 m CS, 20 m with change-of-direction (COD), and 20 m resisted sprints with 20% and 65% of body mass (RS20% and RS65%, respectively). The Pearson product-moment test and Spearman correlation test were performed. RESULTS:Strong correlations were observed between 10 m (r = 0.662; p = 0.001) and 20 m (r = 0.677; p < 0.001) linear sprint times with CS times. Regarding the COD speed, moderate correlations with RS20% times (r = 0.508; p = 0.019) and very strong correlations with RS65% times (r = 0.750; p < 0.001) were observed. Moderate relationships were observed for CMJ with 20 m linear sprint times (r = - 0.467; p = 0.033) and CS times (r = - 0.471; p = 0.031), as well as for SJ and CS times (r = - 0.437; p = 0.047). CONCLUSIONS:This information offers insights for enhancing test sensitivity and tailoring training prescriptions in professional soccer, once correlation was found between groups of tasks with vertical predominance (i.e., vertical jump, curved and linear sprints) and horizontal predominance (i.e., COD and resisted sprints).

Abstract Background Online physical training programs emerged as an innovative approach to avoid the detraining-induced physical fitness impairments during the COVID-19 quarantine period in athletes. However, there is conflicting evidence on the effectiveness of such training programs in soccer players. Aim This study aimed to verify the effects of a 15-week online training intervention during a pandemic quarantine in body composition and physical capacity of highly trained soccer players. Methods Sixteen male under-20 soccer players were assessed after the first period of COVID-19 quarantine (March 2020 to September 2020; 170 days), and after the second period of COVID-19 quarantine (November 2020 to February 2021, 107 days). Body composition, vertical jump height, hamstring maximum strength and aerobic capacity were assessed. The online training program was performed during the second lockdown. Results In comparison with first pre assessments, results showed that fat mass (-0.95 ± 1.27), free fat mass (1.22 ± 1.19), squat jump height (5.36 ± 1.99) and counter movement jump (3.19 ± 3.77) were significantly improved (p < 0.05). However, there were no significant changes in total body mass, hamstring eccentric strength, and Yo-Yo IR1 after online training (p > 0.05). Conclusion In summary, the findings of this study highlight the importance of carrying out an online training program during a period of absence from traditional soccer training, in order to maintain the level of physical capacities of youth soccer players.

Purpose: We examined the effects of two 8-week resisted-sprint training programs under different magnitudes of velocity loss (VL) on the speed-related performance of highly trained soccer players. Methods: Twenty-one soccer players (age: 25.9 [5.4] y) were randomly assigned to 1 of 2 groups: (1) the "moderate-load group," players who trained with sled loads that induced 15%VL relative to unloaded sprint velocity (n = 11); and (2) the "heavy-load group," players who trained with sled loads that induced 40% VL relative to unloaded sprint velocity (n = 10). Linear sprint (10 m), curve sprint, change-of-direction speed, resisted-sprint performance at 15% VL and 40% VL, and vertical jumping ability were tested pretraining and posttraining. A 2-way repeated measures analysis of variance was used to test for differences between groups. In addition, percentage changes were calculated for speed-related abilities and compared with their respective coefficients of variation to determine whether individual changes in performance were greater than the test variance (ie, "true change"). Results: A main effect of time was detected for 10-m sprint, curve sprint, change-of-direction speed, and 15% VL and 40% VL resisted-sprint times, with significant decreases in sprint times (P = .003, P = .004, P = .05, P = .036, and P = .019, respectively). Jump variables did not change significantly over time. There were no group-by-time interactions for any tested variable (P > .05), but the "true change" analysis revealed meaningful individual changes in both groups. Conclusions: Both moderate-and heavy-sled loading conditions may optimize the development of speed-related abilities in highly trained soccer players. Nevertheless, resisted-sprint training responses may differ meaningfully when assessed on an individual basis.

Abstract Loturco, I, Grazioli, R, Veeck, F, Nakamura, FY, Inácio, M, Schons, P, Preissler, A, Pinto, RS, Pereira, LA, McGuigan, MR, and Cadore, EL. Effects of a short-term detraining period on the strength deficit and functional performance of highly trained soccer players. J Strength Cond Res 37(10): 2058–2063, 2023—The aim of this study was to examine the effects of a 4-week detraining period on the neuromuscular performance of highly trained soccer players. Pre and post detraining, 18 adult soccer players (age: 27 ± 4.9 years; height: 180.2 ± 7.1 cm; body mass [BM]: 78.9 ± 7.6 kg) performed vertical jumps, 20-m linear sprints, curve sprint and change of direction speed tests, and a progressive loading test in the half-squat exercise with loads corresponding to 50, 100, and 150% of the players' BM to assess the peak-force (PF), mean power (MP), and strength-deficit (SDef). Pre and post differences in the variables of interest were analyzed using paired t-tests and effect sizes (ES). No significant changes were detected for vertical jumping height and sprint times. Higher PF at 50 and 100% BM and lower SDef were shown when comparing pre- and postassessments (ES = 0.66, 0.68, 0.55; p = 0.018, 0.016, and 0.046, respectively). The MP at 50 and 100% BM increased significantly after the detraining phase (ES = 0.56, 0.82; p = 0.049 and 0.007, respectively). The results indicate that these athletes were able to maintain and achieve satisfactory levels of performance after a short period of training cessation. Interestingly, some strength- and power-derived parameters improved significantly after short-term detraining, which may have important implications for training programs aimed at maximizing speed and power performance. It is recommended that coaches test their players not only at the beginning but also at the end of the season, to better evaluate variations in performance and thus create more efficient and tailored training strategies.

A common pre-season injury prevention assessment conducted by professional football clubs is the hamstring-to-quadriceps (H:Q) strength ratio calculated by peak torque (PT). However, it is debatable whether players that present low pre-season H:Q ratios are more susceptible to further sustaining in-season hamstring strain injuries (HSI). Based upon retrospective data from a Brazilian Serie A football squad, a particular season came to our attention as ten out of seventeen (~59%) professional male football players sustained HSI. Therefore, we examined the pre-season H:Q ratios of these players. H:Q conventional (CR) and functional (FR) ratios, and the respective knee extensor/flexor PT from the limbs of players further sustaining in-season HSI (injured players, IP) were compared to the proportional number of dominant/non-dominant limbs from uninjured players (UP) in the squad. FR and CR were ~18–22% lower (p < 0.01), whereas quadriceps concentric PT was ~25% greater for IP than UP (p = 0.002). Low scores of FR and CR were correlated (p < 0.01) with high levels of quadriceps concentric PT (r = −0.66 to −0.77). In conclusion, players who sustained in-season HSI had lower pre-season FR and CR compared to UP, which appears to be associated with higher levels of quadriceps concentric torque than hamstring concentric or eccentric torque.

Background: The effects of strength training on muscle strength imbalance are unclear in professional soccer players. As a result, this study examined the effects of an 8-week strength training program comprising eccentricemphasized prone leg curl adjusted according to the individual strength imbalance status. Methods: Ten professional soccer players (26.0 +/- 3.6 yrs) participated in the study. Players who had a >= 10% contralateral imbalance in knee flexors eccentric peak torque (n = 6) performed two additional repetitions per set in the low-strength limb (high-volume, HV) compared to the high-strength limb (low-volume, LV). Isokinetic concentric knee extension and concentric and eccentric knee flexion peak torque (PT) and derived contralateral imbalances and conventional and functional hamstring-to-quadriceps ratios (H:Q) were assessed at baseline and after 8 weeks. Differences at baseline were assessed using paired-sample T-tests, and a two-way (limb x time) repeated measures analysis of covariance (ANCOVA) for changes over time. Results: A significant improvement in the eccentric knee flexion PT was observed in both limbs after 8 weeks (P < 0.05), with greater effects observed in the HV limb (25.0 N m, 95% CI: 15.1-34.9 N m). Significant decreases were also observed in the contralateral imbalances from concentric knee extension and flexion and eccentric knee flexion PT (P < 0.05). Differences were not observed in concentric knee extension and flexion PT (P > 0.05). Conclusions: A short-term eccentric-emphasized leg curl intervention adjusted by the initial knee flexors eccentric strength was an efficient method to improve knee flexors strength imbalance in professional soccer players.

Background: Fencing is an agility sport and is characterized by a combination of short and frequent high intensity movements. Proprioceptive training demonstrates a positive effect on athletes' performance. It is effective in increasing dynamic balance by reducing ankle muscle reaction time that stabilize joint. Objective: The aim of this study was to verify influence of a 12-week proprioceptive training program on ankle instability, jumping performance and ankle muscle’s reaction time during Lunge in fencing athletes. Method: The study was a clinical trial, non-randomized, with 19 fencing athletes from 14-35-year-old, divided in intervention group (n=10) and control group (n=9). The study was performed in four stages: familiarization of jump performance; pre-intervention; intervention and post-intervention. At pre-intervention was evaluated jump performance, ankle muscle reaction time and functional ankle instability. At the intervention, athletes performed 30 minutes of proprioceptive training for 12 weeks, three times a week. At post-intervention, the same pre-intervention tests were performed. Data were presented in mean and standard error, submitted to the Generalized Estimates Equations test with Bonferroni post hoc. The level of significance was 0,05. Results: Jump performance decreased significantly in both groups. Anterior tibial muscle reaction time did not differ neither in any of groups, nor in any of legs. The peroneus longus and lateral gastrocnemius reaction time decreased significantly in both groups. Regarding functional ankle instability, athletes had instability at pre- and post-intervention time. Conclusion: Proprioceptive training program was not able to improve jump performance, nor to decrease ankle muscle reaction time or improve athletes' perception of ankle stability.

Abstract Freitas, TT, Pereira, LA, Alcaraz, PE, Cadore, EL, Grazioli, R, Azevedo, PHSM, Jeffreys, I, and Loturco, I. Interrelationships between multiple speed tests in youth soccer: Are players equally efficient at performing different sprint and COD tasks? J Strength Cond Res 37(4): 848–853, 2023—We investigated the relationships between linear and multidirectional sprint tests in elite young soccer players, using different speed measurements and their associated deficits. Twenty-three under-17 and 17 under-16 soccer players performed, on the same day, 17-m linear sprint (with 10-m split times), curve sprints for “good” and “weak” sides (CSGS and CSWS, respectively), and zigzag and 505 change of direction (COD) tests. The Pearson’s product moment test was used to determine the relationships among the tested variables. Significance level was set at p < 0.05. Large and very large significant correlations were observed between CSGS and CSWS and 10-m (r = 0.73 and r = 0.53, respectively; p < 0.0001) and 17-m sprint velocity (r = 0.84 and r = 0.74, respectively; p < 0.0001). Moderate and significant associations were identified between zigzag and 17-m sprint performances (r = 0.40; p = 0.02). No significant relationships were found between 505 performance and 17-m sprint velocity and between the different COD tasks (p > 0.05). Significant correlations were observed between sprint performance at 10- and 17-m and both CS and COD deficits (r values ranging from 0.37 to 0.54; p < 0.05). In general, higher linear sprinting velocities were associated with superior performances in smoother multidirectional tasks (i.e., CS and zigzag tests) but not in more aggressive COD maneuvers (i.e., 505). Faster athletes in linear actions presented greater CS and COD deficits. No associations were detected between the different COD measurements, supporting the notion that the technical and mechanical demands of COD actions are angle and velocity dependent. From a practical perspective, comprehensive speed testing batteries (i.e., incorporating linear sprints, CS, and different COD assessments) should be administered to young soccer players, to better understand their ability to change direction and sprint over multiple trajectories.

This 11-week study aimed to correlate the neuromuscular profile and the total volume of resisted sprint training (RST) under different velocity loss (VL) magnitudes in male professional soccer players. Seventeen soccer players (age 25.8 ± 4.3 years; height 180.0 ± 8.6 cm; weight 77.7 ± 9.7 kg) were randomly allocated into two training groups, who trained at distinct percentages of VL: 10

Muscle strength imbalance assessment (e.g., hamstring-to-quadriceps ratio, H:Q) using traditional peak torque isokinetic measurements has been shown to be a weak risk factor predictor of future lower-limb injuries (e.g., hamstring strain and anterior cruciate ligament tear). In soccer, power-related tasks are commonplace and injuries are most likely to occur during fatigued high-velocity actions. Thus, it is reasonable to that calculating H:Q using power output and may serve as an alternative to traditional peak torque-based H:Q. We aimed to investigate the relationship of isokinetic H:Q calculated from traditional peak torque and power output during non-fatigue and fatigue conditions. Seventy-nine professional soccer players (25.6 ± 4.9 years old; 78.7 ± 8.1 kg; 179.4 ± 6.7 cm) performed concentric knee extension-flexion contractions at 60°.s−1 (five repetitions) and 300°.s−1 (30 repetitions, fatigue trial). Traditional peak torque H:Q was calculated using the highest torque obtained during five repetitions at 60°.s−1. Power output H:Qnon-fatigued was calculated using the average from the 2nd, 3rd and 4th repetitions, and power output H:Qfatigued was obtained as the average of the power output of the last three repetitions of the fatigue trial. Weak (rs = 0.27) and moderate (rs = 0.49) correlations were found between traditional peak torque and power output H:Qfatigued, and traditional peak torque and power output H:Qnon-fatigued, respectively. The present data suggested that power H:Q differs from traditional H:Q, particularly during fatigue in professional soccer players, which warrants further investigation on the potential use of power output H:Q ratios for injury prediction.

This study aimed to investigate the interindividual responses following two different concurrent training (CT) regimens in neuromuscular, cardiorespiratory and functional outcomes of older men. Thirty-five older men (65.8 ± 3.9 years) were randomly allocated into one of two CT groups: power training (PT) + high-intensity interval training (HIIT) (n = 17); or traditional strength training (TST) + HIIT (n = 18). Maximal dynamic strength (one-repetition maximum, 1RM), rate of force development at 100 milliseconds (RDF100), countermovement jump power (CMJ), quadriceps femoris muscle thickness (QF MT), functional tests (sit-to-stand, timed-up-and-go, and stair climbing), and peak oxygen consumption (VO2peak) were assessed pre-, post-8 and post-16 weeks of training. The Chi-squared test was used for assessing differences in the prevalence of responders (Rs), non-responders (NRs), and adverse responders (ARs). Similar prevalence of individual responses (Rs, NRs and ARs) between groups were observed after intervention in almost all outcomes: 1RM; power at CMJ; QF MT, and functional tests (P > 0.05). However, a significant difference in the distribution of Rs, NRs and ARs between groups was observed in the RFD100 after 16 weeks (p = 0.003), with PT + HIIT group presenting high prevalence of Rs than TST + HIIT (100 % vs. 50 %). The inclusion of explosive-type of contractions in a concurrent training regime induces greater responsiveness in the RFD100 in older men, while no differences compared to traditional strength training are observed in maximal strength, muscle size, VO2peak, and functional performance.

BACKGROUND:Volleyball is a complex intermittent sport characterized by short explosive technical movements, many of which involve vertical jumping. The assessment of mechanical jumping variables in relation to both injury prevention and performance enhancement through the use of wearable technologies is becoming a new training tool among professional volleyball players.METHODS:The present study aimed to assess the vertical jumping mechanics before and after a controlled load (volume and intensity) of a routine volleyball training session among male professional players. Twelve male elite professional volleyball players (23.7±4.9 years, 198.1±6.2 cm, 92.2±10.3 kg) of national and international level belonging to the same Brazilian first league team were recruited. Biomechanical analysis of vertical unilateral countermovement jump (CMJ) and bilateral CMJ tests were performed before and after a routine training session of these players at their usual training court. An inertial orientation sensor placed at the third lumbar vertebra was employed for biomechanical data collection.RESULTS:In relation to the unilateral CMJ, a 10% decrease (P=0.02) in the vertical ground reaction force after training compared to pretraining values was observed. However, no significant differences were observed in the remaining outcomes. Regarding the bilateral CMJ, no significant differences were observed in all assessed outcomes.CONCLUSIONS:Our findings showed no evidence of fatigue after a controlled regular in season volleyball training session in professional players. In addition, this volleyball training session induced a significant reduction in the vertical ground reaction force during unilateral CMJ in volleyball players.

Running is a very popular activity and muscle strength imbalance has been treated with caution to prevent injuries. The present study aimed to compare and correlate knee flexion and extension strength imbalance based on peak torque (PT) and total work (TW) in running athletes. Thirty-eight male amateur running athletes (38 ± 6 years; 80.6 ± 8.3 kg; 177 ± 7 cm; 7.8 ± 8.4 years of training; 3.5 ± 0.9 training sessions a week; 33.5 ± 13.4 km of training per week) took part in the present study. Knee flexion eccentric and concentric PT and TW, as well as concentric knee extension PT and TW were assessed. PT- and TW-based hamstring-to-quadriceps ratios (H:Q), as well as PT and TW contralateral imbalance were quantified. A significant correlation was observed between TW and PT concentric knee flexion contralateral deficits (r = 0.52, p < 0.001). No further correlations were found among TW- and PT-based muscle strength imbalance variables (p > 0.05). All mean comparisons of H:Q and contralateral imbalances using TW or PT were significantly different (p < 0.05). Our results showed that TW and PT muscle strength imbalance were unrelated, and the H:Q and contralateral imbalance profile of endurance runners may differ based on the isokinetic variable analyzed.
