Influence of endurance exercise on respiratory muscle performance

Article Abstract:

This article examines the effect of prolonged intense exercise on diaphragmatic muscle fatigue and global respiratory performance. The results indicate that there is a significant reduction in respiratory endurance following exhaustive cycling tests due to fatigue in both diaphragmatic and extra-diaphragmatic muscles.

Evidence of neuromuscular fatigue after prolonged cycling exercise

Article Abstract:

This article examines the metabolic, biomechanical, and neuromuscular effects of a two-hour cycling session on trained athletes. Results indicate that decreases in pedaling rate and muscular capacity after intense cycling are associated with reduced neuromuscular input and peripheral contractile mechanism failure due to fatigue.

Noninvasive measurement of muscle high-energy phosphates and glycogen concentrations in elite soccer players by P(sup)31-and C(sup)13-MRS

Article Abstract:

Results demonstrate that concentrations of muscle adenosine triphosphate, phosphocreatine, and glycogen high-energy phosphates in elite soccer player muscles were similar by the noninvasive magnetic resonance spectroscopy technique and biochemical analysis.
