> Healthy older adults (n = 123, average age 72.0 years, body mass index 25.8 kg/m2) completed three 45-min supervised exercise sessions per week for 6 months. Participants were randomised to treadmill-based moderate-intensity training (n = 45), or high-intensity interval training (n = 41) or a low-intensity active control condition (n = 37), with individualised heart-rate prescription. Dual-energy x-ray absorptiometry was used to quantify body composition at baseline, and at 3 and 6 months.
ok they didn't even include light/moderate weight lifting as another control, so this is a fairly poorly executed study
basically it comapres hiit with treadmill walking in which case yes, it's slightly more useful, but hiit also causes a lot of damage in a lot of ways

Please do explain this.
Technically weight lifting (muscle hypertrophy) also causes "damage" but in a controlled an beneficial way.
I would guess they mean hiit can traumatize e.g. joints or cardiovascular system, especially for the elderly.

Oh! I didn't know about this. Are there any references you could quote?
