High intensity training and treadmill sprint performance.

Abstract

Twelve county standard hockey players completed a 30 second sprint on a non-motorised treadmill and an uphill treadmill running test to determine maximum oxygen uptake (VO2 max) before and after 6 weeks of high intensity training (fast runs 3-5 miles, intervals 30-300m and circuit training), whilst 11 club standard players completed the same tests without any additional training. For the county standard group there was an 11.1% and 5.0% improvement in peak running speed and distance covered on the sprint treadmill respectively, a 4.2% improvement in V02 max and an 11.5% improvement in run time to exhaustion during the V02 max test (all p < 0.01). No changes were observed for the club standard group. There were large increases in blood lactate (county group 13.26 ± 1.83 mM) and blood glucose (county group 1.56 ± 0.71 mM) concentrations as a result of the treadmill sprint, but there were no additional changes in these variables as a result of training. Thus, the mechanism of adaptation in this type of brief maximal exercise remains in question. Key words: Training, Sprinting, Metabolism, Testing INTRODUCTIONThe causes of fatigue and the factors which limit performance in sprint running exercise are not fully understood. One means of studying the factors which limit performance is to examine the responses to training and the metabolic changes which accompany training-induced improvements in performance. Several studies have demonstrated improvements in the ability to perform high intensity exercise after various types of training. Extended run times to exhaustion during uphill treadmill running have been found after both general conditioning

Investigation of Varied Intensity Interval Sprint Training and Detraining Impact on Selected Speed Parameters

“…Four weeks of high intensity sprint interval training combined with endurance training increased motor units activation. Cheetham and Williams (1987) [6] found that 11.1% of improvement in peak running speed following high intensity training. Relatively brief period of sprint training increased anaerobic capacities in initially untrained individuals [7,8].…”

Cardiorespiratory Training for Dancers

“…10,43 Aerobic Power According to Bangso 44,45 the development of VO 2 max is important in the recovery between high-intensity bouts. Research suggests that this is best achieved by interval training [46][47][48] as more work can be performed at higher intensities with the same or less fatigue compared to continuous training. By increasing a dancer's VO 2 max it allows them to carry out the same exercise at a lower relative workload thereby delaying the effect of fatigue, which is a major perceived cause of injury within dance.…”
