Entrenamiento intermitente de alta intensidad en hipoxia simulada como tratamiento en mujeres

Resumen

Hypoxia exposure combined with high-intensity may have a synergistic effect due to the fact that both stimuli regulate crucial pathways in the metabolism of glucose and lipids; and could be considered a new feasible and valuable therapeutic strategy. the aims of the present thesis were a) to update the current scientific status regarding active hypoxia conditions in obese humans and, b) to investigate effects of different HIT in normobaric hypoxic conditions on fat mass and different cardiometabolic risk factors in overweight/obese women. A systematic review was carried out following PRISMA. For the controlled trial, participants included 82 overweight/obese women, who started a 12 week program of 36 sessions, and were randomly divided into four groups: (1) intervaltraining in hypoxia (FiO₂ = 17.2%), (2) interval-training in normoxia, (3) sprint interval-training in hypoxia (FiO₂ = 17.2%), and (4) sprint interval-training in normoxia. Anthropometric and body composition, basal metabolic rate, biochemical and clinical measures were assessed. All four times points for evaluations consisted of the same measurements. The results suggested that combined intermittent hypoxia with exercise may help to improve cardiometabolic parameters in obese people. Highintensity interval training under normobaric intermittent hypoxia during 12 weeks is promising for reducing body fat content with a concomitant increase in muscle mass, causing a decrease in abdominal fat in and, possibly, beneficial changes on triglycerides at the middle of the program. Besides, after a period of 4 weeks of the percentage of fat mass located in the trunk improves significantly.
