Summary
Good sleep duration and quality enhance maximal incremental test performance in healthy men. Poor sleep is linked to reduced peak power output (Wmax) and maximal heart rate (HRmax), independent of fitness level.
Area of Science:
- Exercise Physiology
- Sleep Science
- Sports Medicine
Background:
- Inadequate sleep patterns are linked to metabolic diseases and can impair exercise training performance.
- The specific impact of sleep duration and quality on maximal incremental test performance in healthy men remains unclear.
Purpose of the Study:
- To investigate the association between sleep patterns (duration and quality) and performance during a maximal incremental exercise test in healthy males.
Main Methods:
- 28 healthy males assessed sleep quality and duration via questionnaires (including Pittsburgh Sleep Quality Index).
- Participants underwent a maximal incremental exercise test, with starting workload adjusted for fitness level.
Main Results:
- Maximal heart rate (HRmax) correlated with both sleep quality and duration.
- Good sleep quality was associated with higher peak power output (Wmax) and maximal oxygen uptake (VO2max), and lower HRmax.
- Sleep duration significantly influenced Wmax, independent of VO2max.
Conclusions:
- Sleep duration and quality are associated with maximal incremental test performance in healthy men.
- Impaired sleep patterns can lead to reductions in Wmax and HRmax.
- The relationship between sleep patterns and performance, particularly Wmax, appears independent of an individual's fitness condition.
