The study found no benefit from protein supplementation after exercising LOW-HIIT

Low-Intensity Interval Training (LOW-HIIT) is gaining in popularity thanks to its low time requirements. Researchers from Friedrich-Alexander University Erlangen-Nuremberg in Germany believe it is important to consider the benefits of this type of training.

It is generally accepted that those who perform intense training, recreational sports, or general fitness routines, may need to eat more protein than the sedentary population. However, compared to long-distance endurance training or resistance exercise, the potential of certain nutritional strategies and/or supplementation to enhance physiological adaptations in response to LOW-HIIT has been scantly investigated.

The current double-blind study therefore examined the effect of LOW-HIIT combined with protein supplementation on indicators of cardiovascular health in healthy, sedentary individuals with the hypothesis that the protein-supplemented group would benefit from more appropriate training modifications.

This was, to the researchers’ knowledge, the first randomized, double-blind, placebo-controlled study to investigate the effects of targeted protein supplementation after LOW-HIIT on long-term adaptations to CRF and cardiac metabolic outcomes in previously sedentary individuals.

the study

Forty-seven participants (31.1 ± 8.0 years) performed LOW-HIIT (5-10×1 min with a maximum heart rate of 80-95%) for eight weeks and randomly received 40 g of whey protein (Fresubin Protein, N = 24). ) or isotonic placebo (maltodextrin, N=23) after each session.
