This study compared three groups: weight training with fatigue (6 RM, 6-10 sets, 3 d/wk, for six weeks); weight training with 30 sec rests between each repetition in the sets, and an inactive control group. The fatigue group increased dynamic strength (56.3%) in the elbow flexor muscles significantly more than the rest (41.2%) and control groups (19.7%). It was concluded that greater short-term strength increases are achieved when Ss are required to lift without resting. It was hypothesized that fatigue contributed to the strength-training stimulus. Implication: Strength training repetitions should be undertaken with a goal of achieving a significant fatigue state. Less than maximal application will reduce potential benefits.
