Effects of sprint training combined with vegetarian or mixed diet on muscle carnosine content and buffering capacity
Controlled trialHumans
- Design
- Controlled trial
- Subjects
- 20 omnivorous subjects randomised to vegetarian or mixed diet
- Duration
- 5 weeks of sprint training, 2 to 3 sessions per week
- What was measured
- Carnosine in soleus, gastrocnemius lateralis and tibialis anterior by proton MRS; gastrocnemius biopsy for non-bicarbonate buffering capacity, carnosine by HPLC and carnosine synthase (CARNS) mRNA; 6 x 6 s repeated sprint ability.
What the authors reported
Five weeks of sprint training did not change muscle carnosine or CARNS mRNA. There was a diet by training interaction in soleus carnosine, a non-significant 11 percent rise on the mixed diet and 9 percent fall on the vegetarian diet. Buffer capacity was unchanged by training, CARNS mRNA fell significantly in the vegetarian group, and repeated sprint performance improved with training in both groups. MRS and HPLC carnosine measures correlated (r=0.517).
