INFLUENCE OF AEROBIC AND ANAEROBIC RUNNING WORKLOADS ON MUSCLE ENDURANCE CAPACITY

Abstract

Efficient management of the training process in medium and long distance running requires a precise knowledge of the influence of the individual training work-loads on the organism. The characteristics of muscular fatigue (type, degree and cause of fatigue) are reliable parameters of the changes in the organism after sports exercise. The purpose of this paper is - on the basis of a sample of 8 good middle and long distance runners and the chosen biomechanical, biochemical and functional parameters - to find to what extent does a 6km run; in the vicinity of the "anaerobic threshold velocity" (criterion Vobla); and a anaerobic-lactic running work-load of 5 x 300m; at submaximal velocity with a minute between the runs; cause a drop in the endurance capabilities of the neuro-muscular system, and the role that the central mechanisms of muscular fatigue play in this. The results of the study show that the drop in endurance capability of the neuromuscular system, after a continuous aerobic activity, is greater than after the more intensive anaerobic-lactic interval work-load. The influence of the central mechanisms on the state of muscular fatigue increases after a cyclic monostructural activity, however, with well-trained subjects the influence of central fatigue in no case dominates; or rather surpasses the level of peripheral fatigue. endurance training, optimisation, diagnostic, electrical Stimulation
