Abstract EN

The research aims to identify the effect of HIIT cardio training and wearing a breathing mask on physiological variables, the efficiency of vital organizations, the concentration of erythropoietin (EPO) and the record level of the 5000-meter runners, The youth of New Damietta, who are registered in the Dakahlia region of the Egyptian Federation for Athletics, the Sunni stage of the 2022 AD season, the research group was trained using HIIT cardio exercises with wearing a breathing mask on the experimental group during the period of special physical preparation within the training program for a period of eight weeks.

(5) Weekly training units with a total of 40 training units, unit time (60: 90) minutes, and the results indicated that the training program using HIIT cardio and wearing a breathing mask on the impact of physical variables (periodic respiratory endurance - endurance speed - strength Characterized by speed-endurance force) and physiological variables (rate Pulse - maximum relative oxygen consumption - maximum carbon dioxide output - oxygen consumption rate in milliliters with each heartbeat - pulmonary ventilation - number of breaths - systolic blood pressure - diastolic blood pressure) and improving the efficiency of vital organizations in the blood (sodium bicarbonate - phosphate - Hemoglobin - blood pH - the percentage of lactic concentration in the blood) and the improvement of the concentration of the hormone erythropoietin - the number of red blood cells and the record level of the 5000-meter runners running for the research sample.
