The Effects of Low-Volume High Intensity Interval Training and Circuit Training on Maximal Oxygen Uptake
In Brief
A clinical study evaluating High intensity interval training and Circuit training for High Intensity Interval Training. Completed, enrolled 42 participants across 1 site.
Detailed Summary
High intensity interval training (HIIT) and circuit training (CT) are popular methods of exercise, eliciting improvements in cardiorespiratory fitness (CRF). However direct comparisons of these two training methods are limited.
Study Details
Timeline
Interventions
Participants performed HIIT twice a week for eight weeks. Findings were compared to moderate intensity continuous training which followed the same exercise frequency and duration
The CT group completed a practical seven-station mixed modality exercise circuit (cycle ergometer, rower, treadmill, sit to stand, knee to elbow and leg kickback with bicep curl) at an intensity of 60-80% HRmax twice per week for eight weeks. Participants initially performed 20 minutes of CT with duration gradually increased to the desired 40 minutes as tolerated
