Summary Nine physiotherapists were included in a training programme whose object was to elucidate the effect of isometric contractions of long duration. The isometric endurance of the left elbow flexors was trained 10 times daily until exhaustion. The load was 60% of 1 RM. The elbow joint was kept flexed 90 °, the forearm being horizontal. The training period was 5 weeks with no training on Sundays. Before and after the experiment the subjects had tests of dynamic strength, isometric strength, dynamic endurance, isometric endurance, and the ability to perform repeated isometric contractions of 5 seconds' duration, interrupted by an interval of 2 seconds. The training increased the isometric endurance by 84% and the ability to perform repeated isometric contractions by 219%. On the other hand, the dynamic endurance was only increased by 92.5%, a slight increase when compared with that which may result from experiments training the dynamic endurance. The effect upon the isometric and dynamic strength was moderate, an increase of 11% and 15.4% respectively — moderate when compared with what is obtained by training with maximum loads. The results are discussed.
