Buffering capacity of deproteinized human vastus lateralis muscle
Observational studyHumans
- Design
- Observational study
- Subjects
- 20 men in four groups of five (sprinters/800 m runners, rowers, marathoners, untrained)
- What was measured
- Muscle buffer capacity, carnosine, histidine and fast-twitch fibre percentage from resting vastus lateralis biopsies; treadmill run to fatigue at 20% incline and 3.5 m/s.
What the authors reported
Sprinters and rowers had significantly higher buffer capacity, muscle carnosine and high-intensity run performance than marathoners and untrained men (P < 0.01), who did not differ from each other. Buffer capacity showed only low correlations with carnosine content and fast-twitch fibre percentage (P < 0.05).
Limits of this study
Cross-sectional comparison of trained groups; five per group. Full text not read.
