SPRINT TRAINING UNTRAINED INDIVIDUALS
MacDougall, J. D., Hicks, A. L., MacDonald, J. R., McKelvie, R. S., Green, H. J., & Smith, K. M. (1996). Muscle enzymatic adaptations to sprint interval training. Medicine and Science in Exercise and Sports, 28(5), Supplement abstract 126.
Nine healthy males performed seven weeks of intense interval cycle ergometry training. Training effects were observed in both glycolytic and oxidative enzyme activity. A relatively brief period of sprint training increased aerobic and anaerobic capacities in initially untrained individuals.
Implication. When training is initiated in untrained individuals, all systems respond to the exercise stimulation. It is only at the higher levels of performance/fitness that discriminative training responses occur.
