الملخص EN

The main purpose of this study is to determine the effect of hand cooling recovery device Core Control (AVA) on physiological variables, blood lactate (LA), creatin phosphokinase (CPK), lactate dehydrogenize (LDH), in 200m free style swim.

Method of the Study: Seven welltrained swimmers, volunteer to participate in the study weight (72.93±11.10kg) age (16yr), height (1.75±0.5 M).

The present experiment consisted of two protocols separated by 48 h Protocol (1) Baseline values (b) blood samples were collected, Subjects performed a (10) min freestyle warming up, followed with 200m freestyle sprint test, then passive recovery (PR) for (30) min.

After the passive recovery time, the blood samples were collected and analyzed for (LA-CPK- LDH).

Protocol (2) consisted of the same procedures as Protocol (1) but during the recovery time subjects used hand cooling Core Control device (C) for the same length of time.

The effect of Hand Cooling Core Control device was to decrease the physiological variables (LA- CPK- LDH) in the minutes (2-3-10) but not in minute (1) with ρ≤ 0.05.

The results also show that the Core Control device is effective in decreasing the enzymes that are related to muscles fatigue, in 30 min.

Therefore, it is recommended that Core Control (AVA) device can be used to improve the athlete’s recovery between exercises and competitions.
