Is Grip Strength Related to Metabolic Risk Factors and Cardiorespiratory Fitness?: 1525 Board #200 June 1 9

PURPOSE: Grip strength is very easy to be measured, and is an index to reflect people’s muscle strength. This study aimed at detecting if there are relationships between grip strength and metabolic risk factors and cardiorespiratory fitness. METHODS: The 1925 people were recruited (men: 1425, female: 490; average age 41.33±9.35 yrs) and finished grip test and 835 of them finished VO2max test. Metabolic risk factors (Total cholesterol (TC), triglyceride (TG), LDC-C, HDL-C, fasting blood glucose) were detected. Grip strength (n=1925) was tested in dominant hand, relative grip strength was calculated (relative grip strength = grip strength(kg)/body weight (kg) ×100), and VO2max (n=835) was measured by YMCA cycle test. The relationship among grip strength, metabolic risk factors and VO2max were analyzed after dividing people into several groups by gender and each age of 10 years (20-29yrs, 30-39yrs, 40-49yrs, 50-59yrs). RESULTS: 1) Men’s grip strength and relative grip strength are larger than women’s (grip strength: men: 38.18±7.38kg, women: 22.43±4.68 kg; relative grip strength: men: 54.35±11.55, women: 39.87±8.64), and are negatively related to age (P <0.01). Men’s VO2max is larger than women’s (P <0.01). 2); Relative grip strength of all men is related to TG (P < 0.05), and related to fast blood glucose in men with 30-39yrs and 40-49yrs (r=-0.129, P < 0.01; r=-0.118, P < 0.01), while grip strength of men is only related to TG in 40–49 yrs (r=-0.129, P < 0.05). No relationships in women. 3) In men, VO2max is related to TC and LDC-C (r=-0.211, P < 0.05; r= -0.287, P < 0.01) in 20-29yrs, and related to TG in 30-39yrs (r = -0.296, P < 0.01); in women, VO2max is related to fast blood glucose in 30-39yrs (r=-0.435, P < 0.05) and related to TG in 40-49yrs (r=-0.468, P < 0.05). 4) There is relationship between men’s relative grip strength and VO2max except 40-49yrs group (P < 0.05); no relationship is found in women. CONCLUSIONS: 1) Grip strength decreased with age, and men’s is larger than women’s. 2) Relative grip strength may be a predicted factor of metabolic risk and cardiorespiratory fitness (VO2max) for men. 3) VO2max may be a predicted factor of metabolic risk for adults.
