Summary and conclusions The object of the present study was to investigate the effect of varying the number of repetitions of a dynamic exercise upon 1) isometric strength 2) dynamic strength and 3) endurance. 3 groups of 4 females each were established. They performed 150, 100 and 50 contractions, respectively, per session. They lifted a load of 60% of the One Repetition Maximum (1 RM) by flexion of the elbow joint. A fourth group of 4 subjects was used as a control group. After 30 days of training during 6 weeks there was no increase in isometric strength in any of the groups. However, the training did result in an increase of dynamic strength and endurance. The increase in endurance was tremendous while the increase in dynamic strength was comparatively modest. A possible explanation for this discrepancy is discussed. It has been suggested that the apparent discrepancy in the development of the 2 types of strength is the dependance of the two „strengths“ upon additional and/or different factors. The present paper also lends support to the view that there is a relation between the amount of work performed in training and the resulting increase in working capacity. The present work has been carried out by support from Miss P. A. Brandt's Foundation. The authors are greatly indebted to Mr.Howard Knuttgen Ph. D. for his kind help and suggestive advise during this study.
