A Single Night Of Sleep Restriction Impairs Recovery From Heavy Exercise, John D. Chase
A Single Night Of Sleep Restriction Impairs Recovery From Heavy Exercise, John D. Chase
Masters Theses, 2010-2019
We examined the effects of one night of sleep restriction (Sleep-; 2.5 hrs) on subsequent 3-km cycling performance and skeletal muscle recovery from heavy exercise compared to a full night of rest (Sleep+; 7 hrs). Seven recreational cyclists (n=6 male, n=1 female; age = 24.4 ± 7 yrs; height = 170 ± 10 cm; weight = 68 ± 13 kg VO2max = 61.5 ± 4.4 ml/kg/min) completed four simulated 3-km time trials (TT) and six peak isokinetic torque trials at different speeds (30 and 120°/sec) under both conditions. The first exercise trial (EX1) consisted …
The Effect Of Sleep Restriction On Coagulation And Fibrinolysis After Heavy Exercise, Paul A. Roberson
The Effect Of Sleep Restriction On Coagulation And Fibrinolysis After Heavy Exercise, Paul A. Roberson
Masters Theses, 2010-2019
Introduction: Research has shown exercise elicits a hemostatic response affecting coagulation and fibrinolysis. Furthermore, prior research has determined circadian fluctuations exist where clotting potential increases in the morning as a result of increased PAI-1 and decreased tPA which is further exacerbated by exercise. These circadian fluctuations and exercise responses have the potential to be accentuated by poor sleep. The purpose of this study is to determine the effects of sleep restriction on tPA activity, PAI-1 activity, and Factor VIII antigen activity (FVIII) while resting and after exercise.
Methods: 7 Subjects underwent two similar exercises sessions (EX). EX1 occurred in the …
