Fartlek exercises in two different ways to develop some special physical abilities and functional aspects of the heart muscle for young football players

Abstract

This study aims to investigate the effects of two different methods of Fartlek training on the physical and functional adaptation of young football players, with a particular focus on improving cardiac muscle efficiency and its role in fatigue resistance during matches. The research examines physical and physiological differences before and after implementing the training program to determine the effectiveness of these methods in enhancing athletic performance. The sample was deliberately selected from the players of the Naft Al-Basra Football Club, participating in the Iraqi Professional League for the 2024–2025 season, with a total of 24 players. Specific tests and measurements related to the studied variables were utilized to assess the outcomes.
