Objectives
This study will aim to assess the acute cardiopulmonary differences of a treadmill walking warm□up (WW) versus a suspension warm□up (SW) immediately preceding cardiopulmonary exercise testing (CPET) in recreationally active college□aged adults. The primary outcomes will be to assess differences in peak oxygen consumption, peak heart rate, and peak minute ventilation during CPET following a WW versus a SW. Secondary outcomes will include time to exhaustion, rate of perceived exertion, blood pressure, tidal volume, fraction of expired oxygen consumption, and respiration rate.
Methods
This study will be a randomized counterbalanced crossover design. Participants will complete two separate CPETs over two non□consecutive test days (≥48□h, ≤7□d). During each visit, participants will complete either a WW (6□min at self□selected pace on a treadmill, 0% grade) or SW (6□min dynamic sequence of suspension training exercises), followed by an incremental treadmill CPET protocol up to maximal exertion. Gas exchange, heart rate, blood pressure, and rate of perceived exertion will be measured at rest, after warm-up, during CPET protocol, immediately after, and after 5 minutes of resting. Analyses will use linear mixed-effects models and two one-sided tests for equivalence.
Conclusions
This protocol will determine whether a brief, dynamic suspension training warm□up is a practical and transferable approach or rather different from a traditional treadmill warm-up before CPET in active young adults.
