Scored as 4, very low energy, to 0, full of energy; bscored as 4, exceedingly fatigued or tired, to 0, no feelings of fatigue or tiredness. CAR1 = Central Activation Ratio for the first repetition in the fatigue test. CAR30 = Central Activation Ratio for the 30th repetition in the fatigue test. SBP = systolic blood pressure.
