Abbreviation: RPE, Rating of Perceived Exertion.
a
The load lifted differed significantly between the 3 exercise conditions.
b
Perceived exertion assessed using a 6 (no exertion at all) to 20 (maximal exertion) scale.
c
Tolerability assessed using a 1 (strongly disagree) to 7 (strongly agree) scale in response to the statement, “I have found the exercise session to be tolerable.”
