Physiological reactions and maximum running speed in interval and continuous shuttle tests

The full range of tools, used to evaluate performance and sports training, is expanding by shuttle tests and ways of their compilation. The study of the phenomenology of ergometry and the reactions of body systems helps to substantiate specific for various sports tests and training methods,. 21 football players (20±1 years) performed four works on different days with a stepwise increasing «to failure» speed: 2 interval tests (5sSRTI-40/20, 5sSRTI-20/40) and 2 continuous tests (20mSRT, 5sSRT). The maximum shuttle-running speed (SRSmax), distance and HR were recorded. The rate perceived exertion was evaluated on a scale of 50-100. It was found that the tightness of the connection between ergometric indicators is higher between continuous and between interval tests, which reflects, including HR and RPE, their specificity. To measure and evaluate the level SRSmax, which probably depends on anaerobic abilities, an interval test of 5sSRTI-20/40 is recommended. Aerobic performance (endurance) is more conveniently measured using the 20mSRT, also known as the Luc Leger test.
