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.
