Egypt's COVID-19 co-existence plan insisted on social distancing and keeping closure of physical and sport entities. WHO illustrated the importance of training at home with at least 150 minutes of moderate load exercises or 75 minutes of high load exercises in order to reduce the indoor related health problems such as; anxiety, stress, immunity deficiency, so the study aimed to investigate the Impact of Indoor Training Program Due to covid19 quarantine, on Some Physiological, Physical, and Technical Variables in Elite Wrestlers. 8 professional wrestlers with average age 19.3 years, agreed to participate in 12 week of indoor training. Long period change in training regime with short bouts of resistive physical and technical exercises affected the back flexibility with reduction of 20.673%, physiological variables significantly reduced, maximal oxygen consumption "vo2max", breathing frequency "BF" recorded decrease with 8.781%, 6.132% respectively, ratio between carbon dioxide and oxygen "RER" recorded slight nonsignificant increase with 3.316%, and little change in calorie expenditure showing gradual decrease with stay home effect on wrestlers body. Performance efficiency decreased especially in performance endurance measured in time and score with 34.756%, 16.364% respectively, in correlation with the decrease in physiological variables.
