Effect of One Session of High Intensity Interval Exercise with and without Blood Flow ‎Restriction on Electrical Selected Muscles Activity of Brachial in Active Female

Most of professional athletes are looking for high-level of anaerobic power. In recent years, many measures have been taken on various ways to improve anaerobic power through training. Among several methods, the blood flow restriction (BFR) or Katsu is used to improve performance, moreover electromyography is a useful tool for studying the electrical activity of the muscles as well as the kinetic of motion. Therefore, the present study aims to investigate the effect of one session of severe periodic activity with and without BFR on the electrical activity of selected muscle in the active females.

Ten female students were recruited from University population with age 22.15±0.81 years and BMI 20.08±2.56 kg/m2. The electrical activity of biceps and triceps arm muscles during 4 sets 30 seconds with 5 minutes rest between each set was measured during one session of high intensity interval exercise with hand Wingate test under conditions without and with blood flow restriction. Beside the electrical activity, some anaerobic power parameters such as average and maximum anaerobic power were also measured under both conditions.

The electrical activity of the biceps muscle was significantly increased under conditions with BFR (p < 0.05), but no significant increase was observed in the electrical activity of the triceps superior muscle under conditions with BFR (p>0.05). Among mean anaerobic power and maximum anaerobic power, blood flow restriction only the mean of maximum anaerobic power significantly increased (p < 0.05).

The results showed that the electrical activity of the biceps arm muscle as well as the maximum anaerobic power significantly increased during blood flow restriction. Circulation restriction blood flow seems to be an effective factor in increasing the maximum anaerobic power and electrical activity biceps arm muscle.
