Resting metabolic rate

upin humans1

1 study

  1. Wake bout length increases resting metabolic rate in humans (B = 43.25 kcal, P < .05).

    “higher RMR (B = 43.25 kcal, P < .05)”

Cardiorespiratory fitness

downin humans1

1 study

  1. Wake bout length decreases cardiorespiratory fitness in humans (B= -1.01 ml/kg/min, P < .01).

    “longer WBL was associated with lower VO2peak (B= -1.01 ml/kg/min, P < .01)”
