Baseline testing and training intensity prescription
CONTRACTION
During the baseline testing session, following the resting HR and BP measurements, RPE-EX participants conducted an RPE-based exercise intensity selection protocol. Based on pilot testing, the participants were firstly given 30-s to perform a wall squat, varying the squat height, to select a position that they estimated would elicit an RPE score of 4 after a 2-min contraction. Participants were instructed to change their foot position as they adjusted the squat height to keep their lower leg vertical. Once the participant had selected a squat height, they marked the position using some Blue Tac, stuck to mark the lowest point of contact with the wall (Fig. Squat height marker for RPE-EX group
