Decrement in performance during prolonged avoidance sessions

Wearing lower-body compression garment with medium pressure impaired exercise-induced performance decrement during prolonged running

OBJECTIVE To investigate the effect of wearing a lower body compression garment (CG) exerting different pressure levels during prolonged running on exercise-induced muscle damage and the inflammatory response. METHODS Eight male participants completed three exercise trials in a random order. The exercise consisted of 120 min of uphill running at 60% of VO2max. The exercise trials included 1) ...

Elevation of plasma renin activity during avoidance performance in baboons.

The effect of a 3-h Sidman avoidance operant conditioning schedule (liver pressing to avoid an electric shock) on plasma renin activity and renin substrate concentration was examined in baboons (Papio cynocephalus). Plasma samples were drawn over a 24-h period on both the control and test days, and the avoidance session was presented on the morning of the test day. Plasma renin activity was sig...

Post-exercise serum hepcidin levels were unaffected by hypoxic exposure during prolonged exercise sessions

The purpose of the present study was to determine the influence of hypoxic exposure during prolonged endurance exercise sessions (79 min in total) on post-exercise hepcidin levels in trained male endurance athletes. Ten endurance athletes (mean ± standard deviation; height: 169.8 ± 7.1 cm, weight: 57.1 ± 5.0 kg) conducted two endurance exercise sessions under either a normobaric hypoxic conditi...
