The effect of body mass index and level of physical activity on motor competence women's in life span
تأثیر شاخص توده بدنی و سطح فعالیت بدنی بر شایستگی حرکتی زنان در طول عمر
Background and Aims: Physical health is an important aspect of the health of any society and one of the most basic needs of human life. The present study aimed to investigate the effect of body mass index and level of physical activity on motor competence in women within the age range of 8-85 years in Tehran, Iran. Materials and Methods: The present cross-sectional study was performed on 323 women aged 8-85 years who were divided into five groups, namely children, adolescents, young women, adults, and the elderly. The participants were selected using the convenience sampling method, and the required data were collected using a weight gauge, a height gauge, the short form of the International Physical Activity Questionnaire, and a motor competence test. The collected data were analyzed using multivariate one-factor analysis of variance and Bonferroni test. Results: The results of multivariate one-factor analysis of variance showed that the body mass index had no significant effect on motor competence (P<0.05). The main effect level of physical activity and age group on motor competence variable was significant (P=0.001). Performance of the children group was significantly weaker than that of young women regarding motor competence (P<0.05). Moreover, the performance of female children was better than that of the elderly group in terms of the motor fitness variable. In addition, the elderly group had lower motor competence, compared to children and adolescents. Besides, people with a moderate level of physical activity performed significantly better in the motor competence test than those with low and intense levels of physical activity (P<0.05). Conclusion: The level of physical activity should appropriately increase to enhance motor competence and physical health. Furthermore, the downward trend of motor competence can be delayed by the adoption of proper plans.
زمینه و هدف: سلامت جسمانی از جنبههای مهم سلامت هر جامعه و یکی از اساسیترین نیازهای زندگی انسان میباشد. هدف از مطالعه حاضر، بررسی تأثیر شاخص توده بدنی و فعالیت بدنی بر شایستگی حرکتی افراد 85-8 سال شهر تهران بود. روش تحقیق: مطالعه حاضر از نوع مقطعی بود و روی 323 زن 85-8 سال که به پنج گروه کودک، نوجوان، جوان، بزرگسال و سالمند تقسیم شدند، انجام شد. نمونه‌های تحقیق به صورت داوطلبانه و بر اساس معیارهای ورود به مطالعه انتخاب شدند. برای جمع‌آوری داده‌ها از ترازو، قدسنج، نسخه کوتاه پرسشنامه بین‌المللی سطح فعالیت بدنی و آزمون شایستگی حرکتی استفاده شد. داده‌ها با استفاده از تحلیل واریانس تک عاملی و چندراهه و آزمون بونفرونی تحلیل شد. يافته‌ها: نتایج حاصل از تحلیل واریانس تک عاملی چندراهه نشان داد شاخص توده بدنی بر شایستگی حرکتی تأثير معنادار ندارد (05/0
