: The objective of the study was to investigate the relationship between the level of physical activity and body composition, and the levels of motor skills and strength in overweight and obese men. : The research involved 64 men. Body composition, physical activity, motor control, Motor Control Test (MCT), and strength variables were evaluated. Body composition was assessed by DXA, and the participants were classified into two groups according to the percentage of total fat mass: greater and less than 27.65%. Physical activity was assessed using accelerometry, and motor control was measured with posturography, which provided a composite score of motor performance and postural control effectiveness. Strength was assessed using hand, leg, and back dynamometers. : The participants with a higher percentage of body fat had a lower DSI (Dynamic Strength Index) ( < 0.001) and significantly reduced PAL (physical activity level) and energy expenditure ( < 0.001). No significant differences were found in the muscle strength of the upper limbs ( = 0.06) and lower limbs ( = 0.419). With regard to MCT, there was a significant difference between groups in the backward direction ( = 0.041), with the group with the highest percentage of body fat showing lower values. : Individuals with a higher percentage of body fat tend to have lower levels of strength, physical activity, and energy expenditure, which can lead to impaired balance. The findings highlight the need for targeted interventions to improve body composition and levels of strength and physical activity, with a positive impact on general health and quality of life. Emphasis should be placed on improving physical activity levels in male individuals with a higher percentage of fat mass to improve their body composition and dynamic strength levels, which are beneficial to life, particularly to help improve postural control.
本研究的目的是调查超重和肥胖男性的身体活动水平与身体成分之间的关系，以及运动技能和力量水平之间的关系。该研究涉及64名男性。对身体成分、身体活动、运动控制、运动控制测试（MCT）和力量变量进行了评估。通过双能X线吸收法（DXA）评估身体成分，并根据总脂肪量的百分比将参与者分为两组：大于和小于27.65%。使用加速度计评估身体活动，使用姿势描记法测量运动控制，姿势描记法提供了运动表现和姿势控制有效性的综合评分。使用手部、腿部和背部测力计评估力量。身体脂肪百分比更高的参与者动态力量指数（DSI）更低（<0.001），身体活动水平（PAL）和能量消耗显著降低（<0.001）。上肢（P = 0.06）和下肢（P = 0.419）的肌肉力量未发现显著差异。关于MCT，在向后方向上两组之间存在显著差异（P = 0.041），身体脂肪百分比最高的组显示出较低的值。身体脂肪百分比更高的个体往往力量、身体活动和能量消耗水平较低，这可能导致平衡受损。研究结果强调了有针对性干预的必要性，以改善身体成分、力量和身体活动水平，对总体健康和生活质量产生积极影响。应强调提高脂肪量百分比更高的男性个体的身体活动水平，以改善他们的身体成分和动态力量水平，这对生活有益，特别是有助于改善姿势控制。
