The effectiveness of specific exercises using high-intensity interval training on enhancing certain physiological and physical levels among U17 handball players

Handball is considered one of the team sports that differ in its performance charac-teristics from many other team games. It requires specific attributes, including maximal aerobic speed and maximal oxygen uptake. This study aimed to examine the effectiveness of a set of specific exercises using interval training in improving maximal aerobic speed in handball players. The study sample was selected from teams affiliated with the Batna Handball League, within the age group of 15 to 17 years. A purposive sampling method was employed, resulting in a selection of 14 players who underwent a series of high-intensity interval training sessions. The 20-meter maximal aerobic speed test was used to evaluate performance before and after a series of high-intensity interval training sessions. The results indicated a statistically significant improvement in maximal aerobic speed. These findings suggest that high-intensity interval training is an effective method for improving maximal aerobic speed and maxi-mal oxygen uptake (VO2max) in handball players.
