The training and detraining effect of high-intensity interval training on post-exercise hypotension in young overweight/obese women

Abstract

The findings suggest that six HIIT sessions is sufficient to affect clinically significant PEH responses in young, overweight/obese women; however, the training effects are lost within 2 weeks of detraining.

Preliminary safety analysis of high-intensity interval training (HIIT) in persons with chronic stroke

“…Hypotensive responses following high intensity exercise in healthy male adults and in overweight women have been shown to be both intensity and modality driven (Eicher et al 2010;Bonsu and Terblanche 2016). Therefore, given the known transient increase in stress on the cardiovascular system associated with increases in training intensity, coupled with the intention of the HIIT protocol design to increase HR's above what would be attained through more traditional forms of aerobic interval training, it is prudent to establish safety guidelines for using HIIT in clinical populations.…”

Detraining effect on overweight/obese women after high‐intensity interval training in hypoxia

“…Possible mechanisms underlying the fat loss effect induced by high‐intensity interval training (HIIT) are undetermined, but may include enhanced exercise and post‐exercise fat oxidation and suppressed post‐exercise appetite . However, beneficial training effects usually return to near resting values within only 2 weeks of detraining after HIIT programs . The effectiveness of different types of health and exercise interventions is not only determined by reducing cardiometabolic risk factors; information about maintenance of the benefits achieved during the detraining period is essential .…”

“…Training cessation is sometimes usual in this population, especially due to travel and holidays which may interrupt training for a relatively long period . Although the number of studies is quite limited, some of them have reported evidence of the effects of detraining after different protocols of exercise in the obese population …”

“…7 Although the number of studies is quite limited, some of them have reported evidence of the effects of detraining after different protocols of exercise in the obese population. 5,6,[8][9][10] Promising benefits on fat mass and biochemical components were previously reported after applying programs of moderate active hypoxic exposure. [11][12][13][14] After exercising at 15% 13,14 inspired fraction of oxygen (FiO 2 ) for 12 weeks or 14.5%, 11 improvements in the percentage of fat mass, glucose, triglycerides, or HDL cholesterol were observed.…”
