Long-term Time-Restricted Feeding (16/8 protocol, 4 weeks) improves Wingate Test mean power and total work output in well-trained young men, whereas short-term TRF (1 week) yields no performance or body composition changes.
If you are a trained athlete, try an 8-hour eating window (e.g., 1 PM to 9 PM) for at least 4 weeks while maintaining your normal training and eating enough calories. Do not expect performance changes in the first week; benefits on anaerobic power (like sprinting or HIIT capacity) tend to emerge after a month of consistent adherence.
WnT mean power and total work output increased post-four weeks of TRF... TRF did not elicit any changes in WnT performance or body composition one week post-intervention.
Why this rating
Randomized crossover design with small sample size (n=12) and short duration (4 weeks).
