Abstract
Can analysis of performance and neuromuscular recoveries from repeated sprints shed more light on its fatigue-causing mechanisms?
Highlights
In team sports, game decisive events are often reliant on transient repeated-sprint ability (RSA), which refers to the ability to produce the best possible average sprint performance over a series of sprints (
The consistent finding was that acute moderate hypoxia or the induction of pre-existing locomotor muscle fatigue caused significant parallel reductions in Root Mean Square (RMS) activity of the active musculature and in power output with cycle-sprint repetitions, while the amount of peripheral quadriceps fatigue incurred at exercise termination was similar
In an effort to resolve this issue, innovative approaches have emerged, either based on the determination of the power-EMG relationship during warm-up sprints that are subsequently compared to EMG changes during a RSA test (Bishop, 2012) or based on the comparison of fatigue responses during two sets of repeated sprints separated by a recovery period and matched for initial mechanical output (Mendez-Villanueva et al, 2008)
Summary
Game decisive events are often reliant on transient repeated-sprint ability (RSA), which refers to the ability to produce the best possible average sprint performance over a series of sprints (
