Pushup Performance by Women: Analysis of Modes of Failure.
Abstract
To analyze the modes of muscle failure during pushups in active duty women determining a single 'weak link' in performance multiple modes of failure. Twenty-five U.S. Army active duty women were prospectively studied. Each participated in eight sessions,separated by a minimum 48 hours, consisting of stretching warm ups then prefatigue ot a specific muscle group to muscle failure with a predetermined exercise. The initial session set a baseline without prefatigue, the following sessions prefatigued the trapezius, latissimus dorsi, deltoid, pectorals, biceps, triceps, and abdominals. Studied 25 women, mean age of 33.5 yrs (23-50 yrs), 19 enlisted and 6 officers with a mean weight of 135.9 lbs (90-180 lbs). Baseline mean was 22 pushups (11-40). Prefatigue of pectorals gave a mean of 9 pushups (2-26), triceps mean 11 pushups (2-25), deltoid mean 15 pushups (0-30), abdominals mean 16 pushups (0-29), biceps mean 17 pushups (8-29), latissimus dorsi mean 17 pushups (9-31), and the trapezius mean 19 pushups (6-32). Prefatiguing of the pectorals and triceps give a significant decrease in pushups compared with other muscle groups (p 0.0005).
