Abstract
Introduction:The face is one of the biometric tools in identifying the characteristics of individuals.The purpose of the research is to investigate the relationship between some facial biometric factors and performance indicators of non-athletic children aged 9-11.
Method:The present study was a descriptive research with correlational design. The statistical population of this study was all male students in the second to fifth grade of elementary school in the north of Marand County, of which160 people met the conditions for entering the study. Facial biometric dimensions were measured by taking images under standard conditions and analyzing them using the pixelation method in two views including full-face and half face. Sports performance indicators included aerobic power, Claw strength and balance that were measured with a6-minute fast walk test, grip dynamometer, and stork test respectively.Data analysis was performed using Pearson's parametric correlation test. All statistical calculations were performed with SPSS version21software at a significance level of 5%.
Findings:There is a significant correlation between the face length to face width ratio variable with aerobic power (p=0.004,r=0.317), grip strength (p=0.014,r=-0.270), there is also a significant correlation between the nose length to nose width ratio variable with aerobic power (p=0.027,r=0.244). In addition, there is a significant correlation between the nose tip angle variable and static balance (p= 0.007,r= 0.298), The mentolabial angle variable with grip strength (p=0.049,r=-0.215).
Results:According to the results obtained in this study, facial biometric indicators that are a function of heredity and have the least impact from the environment are effective on developable and changeable functions such as aerobic power, strength and static balance.

Abstract
Covid 19 disease is associated with a wide range of clinical symptoms and long-term complications. For most sports medicine professionals, it's a new challenge for people to resume their previous activities after recovering from Covid 19 after receiving the exercise prescription and care. The aim of this study was to review the appropriate physical activity for those recovering from Covid 19 infection based on the type of involvement they developed during the illness. For this study, a review study method was selected. This is done in three steps. In the first stage, physical activity in Quid, in the second stage, organ involvement in Quid, and in the third stage, sports prescriptions in organ involvement by searching for appropriate keywords in reputable scientific databases such as Pubmed, ACSM, SID. ir and Science Direct were searched, content related to the purpose of the articles were extracted and collected and analyzed for content. Examination of organs after recovery from Covid 19 infection is essential to return to physical activity. Physical activity prescriptions in those recovering from Corona varies from disease to patient, and organ to organ. Exercising in Covid conditions requires consideration. The cardiovascular, respiratory, blood, gastrointestinal, and musculoskeletal systems are affected by Covid 19 infection. Exercise, on the other hand, has different effects on the immune system depending on its severity, and the immune system undergoes changes in Covid 19 disease. The type, intensity, and duration of exercise or physical activity vary according to the patient and the symptoms or side effects left by Quid, and the readiness of the various organs for physical activity should be assessed.
