Effects of a Suspension Training Warm-up on Cardiopulmonary Exercise Performance

CPET is the gold standard for assessing aerobic fitness. Warm-up procedures may influence outcomes. Traditional CPET warm-up uses walking or cycling, but suspension training provides a dynamic, full-body option. This randomized, counterbalanced crossover study will compare VO₂max and secondary outcomes (time to exhaustion, HRmax, RER, VE, BP, VT) after treadmill vs suspension training warm-up. The primary analysis is a non-inferiority test with a 5% margin for VO₂max.
