Low- and high-intensity one-week occlusion training improves muscle oxygen consumption and reduces muscle fatigue.

Background: Low-intensity resistance exercises with blood flow restriction have been shown is effective to increase muscular strength and hypertrophy. However, the effects of combined training: one-week occlusion training with various exercise intensities by using less occlusion pressure on muscle strength improvement, fatigability and their work capacity are not clear.

Methods: Participants (N.

Blood flow restriction late in recovery after heavy resistance exercise hampers muscle recuperation.

Purpose: This study aimed to examine the effect of acute blood flow restriction during the late recovery phase between two resistance exercise bouts on muscular endurance and oxygenation.

Methods: Amateur male middle- and long-distance runners performed two bouts of one-leg dynamic plantar flexion exercise to failure with the load equivalent to 75% of maximum. Subjects were randomly assigned into two experimental groups with thigh occlusion pressure between bouts at either 120 or 200 mmHg with 20 min of passive rest in between, and two control groups without any blood flow restriction separated by either 5 or 20 min of rest.

Effect of Electrical Myostimulation on the Function of Lower Leg Muscles.

Electrical myostimulation (EMS) method is applied to improve skeletal muscle function. The aim of this study was to evaluate the efficacy of EMS applied to the sole and calf muscles on their strength and on maximal sprint performance. Each of 10 training sessions involved 10 seconds of stimulation and 50 seconds of rest for a total of 10 minutes.

Cardiovascular changes during the performance by nonathletes of Bosco repeated jumps anaerobic test.

Objective: The aim of this study was to find out the characteristics of cardiovascular changes when performing Bosco repeated jumps anaerobic test depending on the duration of jumping in a nonathletes cohort.

Materials And Methods: Changes in arterial blood pressure indices and changes in 12-lead ECG indices were analyzed. The characteristics of recovery after workloads were assessed by evaluating the time of half period of recovery of registered indices and by the Lyapunov exponent.

Effect of lower body compression garments on hemodynamics in response to running session.

Purpose: Compression garments are often worn during exercise and allegedly have ergogenic and/or physiological effects. In this study, we compared hemodynamics and running performance while wearing compression and loose-fit breeches. We hypothesized that in neutral-warm environment compression breeches impair performance by diminishing body cooling via evaporative sweat loss and redistributing blood from active musculature to skin leading to a larger rise in body temperature and prolonging recovery of hemodynamics after exercise.

Restoration of the work capacity of the skeletal muscle with electrical myostimulation.

The aim of this study was to evaluate the effects of applying mild electrical myostimulation (EMS) or passive rest (PR) on restoring the work capacity (WC) of the skeletal muscles in athletes. Nineteen long-distance runners participated in the study. They were divided into 2 groups according to the principle of rotation: a PR (control) and an EMS (experimental) group.

Influence of short breathing stop on the cardiovascular system during exercise testing.

Breathing is both a voluntary and an involuntary action, and the changes in breathing intensity or breathing stops has an influence on vegetative functions of the body during exercise. The aim of this study was to determine the possible changes in cardiovascular parameters when patients shortly stopped to breath at the beginning of exercise testing. MATERIAL AND METHODS.

The effect of passive foot flexion on blood circulation in sports and clinical medicine.

Unlabelled: The aim of the study was to analyze the effect of the passive foot flexion on peripheral and systemic blood circulations in the state of rest of persons adapted to endurance physical loads, and on patients during surgery.

Methods: In the first series of experiments which included 16 males in recumbent supine position adapted to endurance physical loads, the effect of the passive foot flexion by applying a leg muscle activator on the systemic and peripheral blood circulations was analyzed. In the second series of experiments conducted with 6 males and 12 females, the passive foot flexion was aimed at preventing thromboembologenesis during the intraoperative period.
