Three groups of subjects were involved in a ten-were training programme designed to increase arm strength. There were 26 subjects in each group: those in the experimental group,staticanddynamic,exercised twice weekly in the test range, while thecontrol groupremained unexercised. Pre- and post-training static strength scores were obtained at six equidistant points (12#xB0; apart) in the middle one-third (60#xB0;) of the 180#xB0; range of movement of the fully extended right arm in the forward horizontal plane. Reliability coefficients were high. The strength increases for both static and dynamic training wore significant; however, this did not obtain for thecontrol group. The results of ananalysis of covarianceshow that the strength gain associated with static training is significantly, greater than that following dynamic training. The significant strength increases resulting from hath programmes were evenly distributed over the angular range investigated.
