Sex Differences in High-Intensity Interval Training

Post by AlbertY » Sun Feb 16, 2020 5:14 pm

One previous study compared 3 different exercise regiments and ranks HIIT as the best pro-longevity exercise form. Now, this new study gives us some insight into how to optimize HIIT in different sex.

High intensity interval training (HIIT) is an extremely popular form of exercise training; however, few studies have investigated sex differences in response to HIIT. Male and females completed a four week HIIT intervention (eight total sessions) with one group sprinting 4x30s with 30s rest and the other group sprinting 4x30s with 180s rest. The primary outcome variable was speed decrement over the four sprint intervals from the baseline session to the last training session. Females completing the HIIT protocol with short rest (30s) showed a lower speed decrement from baseline to the last session with no changes observed with longer rest (180s). Males showed no changes in speed decrement with either protocol. These findings suggest greater ability to recover in females, so training protocols for females should consider shorter recovery periods to maximize training adaptation.

This could change the way that we train our athletes. Knowing that the female can recover quicker allows for greater stress to be applied for each training session. Interesting study and it will be interesting to see if future studies carry the same results

Thanks for sharing, AlbertY! Useful information that I can put to use in my own training regime. :D
