Descrizione dettagliata
Participants will be randomized to a regular treadmill walking condition or treadmill walking with blood flow restriction (BFR) condition. In both groups participants will complete 32 minutes of treadmill walking at a speed and grade that elicit 40-50% heart rate reserve. In the BFR group the cuffs will be inflated based on each participants individualized limb occlusion pressure (LOP). The cuffs will remain inflated for the entire session but will deflate for 1 minute every 10 minutes based on safety recommendations. The percentage of LOP will 60%. Blood samples will be obtained pre-exercise (PRE), during the final 2 minutes of the final occlusion cycle (OCC), and 3 minutes into the recovery period post-exercise (POST) to measure outcomes.
