The study just published in Medicine and Science in Sports and Exercise subjected 24 overweight women to an 8-week high intensity interval training (HIIT) program, whilst providing a randomised mix of caffeine and placebo supplementation before each training session. Over the course of the eight weeks researchers measured participants’ body fat, testosterone, cardiorespiratory, anaerobic fitness and glucose tolerance levels.
The findings confirmed a number of things.
Firstly, HIIT was found to help women lose body fat and reduce its associated health adversities, such as androgenicity. However, HIIT has also been linked to certain side effects, such as endotoxemia (inflammation caused by increased endotoxins in the blood) and hyperinsulinemia (excess insulin levels).
This is where the caffeine comes in. The researchers found that caffeine supplementation did indeed ameliorate these offsets, by for example restraining the rise in women’s insulin levels caused by HIIT- and optimising HIIT’s positive outcomes overall.
Caffeine continues to kick goals.
