Intermittent-Sprint Performance and Muscle Glycogen Following 30 H Sleep Deprivation.
Looks like missing a night's sleep:
- reduced muscle glycogen levels
- the force that could be applied through the quads
- the activation of the quads
- worsened sprint performance
- worsened mood
CONCLUSION: Sleep loss and associated reductions in muscle glycogen and perceptual stress reduced sprint performance and slowed pacing strategies during intermittent-sprint exercise for male team-sport athletes.Not a surprise I suppose, but interesting. Losing a night's sleep wrecks you!
