Strength diagnosis: the use of test data to determine specific strength training

The aim of this study was to determine if pre-training strength and power tests could provide data that effectively discriminated between subjects whose cycling performance improved considerably from training, from those who did not. Twenty active healthy male subjects performed 10 weeks of plyometric or weight training. Prior to and at the completion of the training, the following tests were performed: (1) a 6-s cycle ride; (2) isokinetic leg extension at 1.05 and 5.24 rads s-1; and (3) a maximum isometric squat. The subjects in the two training groups were separated into those whose cycling performance improved significantly as a result of the training (good) and those who did not (poor). The pre-training muscular function tests of the good versus poor achievers were then compared, individually for each form of training, to determine if they could be used to discriminate between the two subject groups. The pre-training isometric data effectively discriminated between those individuals who improved their cycling performance significantly as a consequence of training and those who did not. While this finding has practical implications for the exercise science field, further research is required before generally useful normative data can be used with confidence to prescribe individual specific training programmes.
