Влияние ишемического прекондиционирования перед тренировкой на работоспособность и артериальное давление мужчин с метаболическим синдромом

Abstract

Remote ischemic preconditioning has been demonstrated in many studies to produce a positive effect on muscle performance as well as on short-term and long-term blood pressure adaptive responses. The aim of this paper was to study the effect of remote ischemic preconditioning performed before strength exercise on perceived exertion, performance levels, and arterial pressure in individuals with metabolic syndrome. Materials and methods. The study involved 30 non-exercising men (mean age 35.2 ± 6.4 years) with metabolic syndrome. The participants were divided into three groups: ischemic preconditioning + resistance training; placebo + resistance training; resistance training. We assessed the level of perceived exertion, number of repetitions in a set, as well as average and total training volume before and after the intervention (ischemic preconditioning or placebo). Systolic, diastolic and mean arterial pressure were measured before the intervention (T0), immediately after the intervention and exercise (T1), 15 min (T2) and 30 min (T3) after exercise. Results. We found that after the intervention the level of perceived exertion was statistically significantly lower, while the average number of repetitions in a set and average and total training volume were higher in the group “ischemic preconditioning + resistance training” compared to the other two groups (р ˂ 0.05). In addition, we observed a more pronounced decrease in systolic and mean arterial pressure in dynamics from T0 to T3 in the group “ischemic preconditioning + resistance training” compared to the other two groups (р ˂ 0.05). Thus, remote ischemic preconditioning used before resistance training can reduce perceived exertion, increase total training volume, and lead to more pronounced post-exercise hypotension in individuals with metabolic syndrome.
