INTRODUCTION:
Large increases in 1-repetition maximum (1RM) strength have been demonstrated from repeated testing, but it is unknown whether these increases can be augmented by resistance training.
METHODS:
Five trained individuals performed a 1RM test and maximal voluntary isometric contraction (MVC) for unilateral elbow flexion exercise on 1 arm (testing arm), while the other arm performed a 1RM test and MVC, in addition to 3 sets of exercise (70% 1RM) (training arm) for 21 straight days.
RESULTS:
Although only the training arm had increased muscle thickness [mean: 0.28 (95% confidence interval: 0.22 - 0.33)] cm, 1RM strength increased similarly in the training [2.2 (95% confidence interval: 0.9 - 3.4) kg; P=0.008] and testing [1.9 (95% confidence interval: 0.5 - 3.2) kg; P=0.019] arms.
DISCUSSION:
Increases in 1RM strength from resistance training are related to the specificity of exercise and are likely driven by mechanisms other than muscle growth
