A doctoral thesis was discussed at the College of Physical Education and Sports Sciences at Al-Qadisiyah University, titled “Physiological Analysis of the Pre-Respiratory Compensation Point (RCP) Stage until Exhaustion and Some Physical Abilities of Handball Players.” The thesis was presented by student Najla Ali Hussein, under the supervision of Prof. Dr. Falah Hassan Abdullah.
The thesis aimed to identify the time of occurrence of the first and second refraction points of pulmonary ventilation in handball players, as well as to identify the physiological characteristics of the first and second refraction stages, up to exhaustion, for handball players.
The most important conclusions are that there is a variation in the physiological variables of the first refraction (anaerobic threshold) and the second refraction at the respiratory compensation point for handball players. There is also a variation in the time of occurrence of the first refraction and the second refraction for handball players.
The most important recommendations are to conduct physiological and physical tests according to scientific principles when selecting handball players to determine their physiological and physical competence. Coaches should also periodically determine the respiratory compensation point for each player to enable them to design individual training programs. A minute for handball players
