Summary

The aim of this study to increase understanding of physiological and functional perturbations following a continuum of exercise stressors.

Detailed description

This study utilised a between groups design, with a within-groups control. This allowed the within-subject profiling of recovery during both a control and exercise week. This design also allowed each group to perform an ecologically valid exercise session as well as having markers of recovery tailored to the areas of interest specific to each cohort. By having each group perform a non-exercise control week, this gives valuable information on the reliability and smallest worthwhile change for a range of both novel and commonly used recovery markers.

Interventions

Type	Name	Description
OTHER	Resistance exercise weight training session	A resistance exercise session was performed. Following a warm-up that consisted of five-minutes cycling at a self-selected intensity, as well as three progressive lifts at 50, 75, and 90% 6 rep max (RM), participants performed four sets of six repetitions at 100% of 6RM (as determined by the maximal weight lifted during the maximal strength assessment) of the following lifts; back squat, front squat, good mornings, and Bulgarian split-squat. Two minutes rest was afforded between sets and exercises.
OTHER	High-Intensity stochastic cycling session	A high-intensity stochastic cycling session was performed. The cycling protocol was performed using a magnetically-braked cycle ergometer (Velotron, RacerMate). Following a 10 minute standardised warm-up including 3 × 3s sprints, participants completed a simulated road-race, consisting of sprints of varied length, differing work to rest ratios and short time-trials.
OTHER	Simulated Team sport protocol	A simulated team sport protocol was performed. Participants performed a standardised warm-up consisting of performing three laps of the circuit jogging, and three laps at 50, 75, and 90% of perceived maximal speed. Participants were then afforded five minutes to perform self-selected stretching prior to commencing the session. Participants performed two sets of 45 minutes of the simulated team sport protocol, separated by 15 minutes rest. Each 45 minute period consisted of a one minute circuit repeated 45 times that replicates typical movement patterns observed during team sports and includes walking, jogging, jumping, sprinting, agility, and decelerations. Each circuit was initiated on the minute, therefore enabling participants to rest following the completion of each circuit. Pilot testing showed participants completes each circuit in approximately 48-55 seconds (sec) therefore enabling 5-12sec rest after each circuit.
