Abstract

The present study identifies the effect of active rest and stretching on some biochemical variables in the blood and peripheral fatigue through the performance of anaerobic glycolysis exercises in football players. The study aims at identifying the concentration levels of Acetylcholinesterase (AChE), Nicotinamide adenine dinucleotide (NAD+), Glucose-6-phosphate dehydrogenase (G6PDH), Lactate dehydrogenase (LDH) in the blood in the post-test measurements of both the experimental and control groups; comparing and identifying the differences in the concentration of these variables in both groups; comparing and identifying the differences between the effects of anaerobic glycolysis exercises and active rest on the concentration levels of the variables in the experimental and control groups in the immediate post-test measurements and after 45 minutes. The sample consists of 12 football players, purposively selected and divided into two gro each one composed of 6 players. The study has found an effect of anaerobic glycolysis exercises on the concentration of all research variables. The recovery of all variables continued during passive and active rest periods and stretching (45 minutes) for both groups. In the experimental group, active rest and stretching result in the decline of ACHE, NAD+, and LDH, while no significant differences between the immediate post-test measurement and after 45 minutes in G6PDH exist. Active rest between repetitions have not increased recovery of the research variables in the experimental group. Meanwhile active rest and stretching have increased the recovery of all research variables.
