How long endurance cycling and recovery diet affect muscle fat stores in trained men
AI simplified
Abstract
IMTG content in vastus lateralis muscle decreases by 21.4% during prolonged endurance exercise in trained male cyclists.
- IMTG content significantly increases during recovery after exercise when a normal fat-rich diet is consumed.
- Preexercise levels of IMTG are reached within 48 hours of recovery on a normal diet.
- Significantly higher IMTG content is observed in type I muscle fibers with a normal diet compared to a carbohydrate-rich diet.
- IMTG repletion is substantially impaired when following a typical carbohydrate-rich athlete's diet.
- Both magnetic resonance spectroscopy and quantitative fluorescence microscopy provide valid measurements of IMTG content.
