Presentation Abstract
This study will examine the effect of work interval duration on the local metabolic stress and cardiac work during low-intensity aerobic exercise with BFR. Healthy males (18-25 yrs) will complete a graded exercise test to determine WR. Participants will complete three experimental intervals (INT) exercise protocols with intermittent BFR, randomly. All protocols will consist of a 4-min warm-up ([20 W] WU), work INTs (35% peak power), and 1-min recovery INTs (20 W) between work INTs. The work INTs will be: 1) six 2-min INTs (2-min INT), 2) twelve 1-min INTs (1-min INT), and 3) three 4-min INTs (4-min INT). During work INTs, BFR cuffs will inflate to 60% of limb occlusion pressure (LOP) and deflate during recovery INTs. Duration of work INTs and BFR will be 12 mins. Gas exchange, heart rate (HR), and tissue oxygen saturation (StO2) will be collected. StO2 will be averaged over the last 30 sec of WU and expressed as change from WU. Blood pressure (BP) will be taken, and calculated rate pressure product (RPP) will indicate cardiac work. Due to different protocol durations, data will be compared at certain percentage of each protocol duration. Differences between protocols will be determined by a 2-way (trial x time) repeated measures ANOVA. Significance will be established if p ≤0.05. It is hypothesized that 4-min work INTs leads StO2 to decrease from WU and RPP greater. If the hypothesis is confirmed, training with longer intervals could elicit greater local adaptations, and higher cardiac work.
