According to researchers from Norway, supervised high-intensity interval training has become more widely used as an exercise intervention for heart disease patients. Recently, they determined that home-based HIIT can also be effective at improving health scores in this group.
The study included 90 mostly male heart disease patients with a mean age of 57. Participants were placed into three groups: group exercise, treadmill exercise and home-based exercise. The groups completed two HIIT workouts per week at 85%–95% of peak heart rate for 12 weeks within the confines of their exercise modality. There was no information available on the specific protocols used. Peak oxygen uptake was the primary measure used to determine any improvements.
Some home-based participants did not complete the exercise protocol as requested, so their data was eliminated. However, when researchers compared compliant home-based exercisers with the other two groups, they found that everyone had achieved similar significant fitness improvements. Home-based exercisers tended to be more physically active overall compared with participants in supervised sessions.
