【摘要】：目的探討我國(guó)45~60歲中年男性肌肉力量的增齡性變化的規(guī)律,以及最大肌肉力量及爆發(fā)力隨年齡變化的相關(guān)性分析。方法通過(guò)自主研發(fā)的數(shù)字化等長(zhǎng)肌肉收縮功能檢測(cè)系統(tǒng),對(duì)總共240名45~60歲中年男性進(jìn)行肌肉力量等長(zhǎng)肌力測(cè)試,包括左右肘關(guān)節(jié)、左右膝關(guān)節(jié)屈伸最大肌力及爆發(fā)力的測(cè)試,同時(shí)采集肢體形態(tài)指標(biāo)(包含體質(zhì)量、瘦體質(zhì)量、上臂及大腿圍度)的數(shù)據(jù)信息。對(duì)每一年齡段受試者采集到的肌肉力量等數(shù)據(jù)進(jìn)行統(tǒng)計(jì)分析,與相對(duì)應(yīng)年齡段受試者肌肉力量及身體形態(tài)指標(biāo)進(jìn)行相關(guān)性分析。結(jié)果 45歲以上中年男性左右肘、膝關(guān)節(jié)屈伸肌肌肉力量呈現(xiàn)逐年緩慢下降的趨勢(shì),其中肌肉爆發(fā)力下降趨勢(shì)最明顯。對(duì)45~60歲中年男性上、下肢最大肌力與體質(zhì)量、去脂體質(zhì)量、上下肢體圍度等身體形態(tài)指標(biāo)的關(guān)系進(jìn)行相關(guān)性分析,結(jié)果發(fā)現(xiàn)45~60歲中年男性左右肘、膝關(guān)節(jié)屈伸最大肌力與體質(zhì)量、去脂體質(zhì)量、上下肢體圍度呈顯著的正相關(guān)性;而與年齡增長(zhǎng)呈負(fù)相關(guān)性。結(jié)論 45~60歲中年男性肌肉力量、耐力及爆發(fā)力與年齡增長(zhǎng)呈負(fù)相關(guān)性;與體質(zhì)量、去脂體質(zhì)量、上下肢體度呈顯著的正相關(guān)性。
[Abstract]:Objective to investigate the age-related changes of muscle strength in middle-aged men aged 45 years and 60 years old in China, and to analyze the correlation between maximum muscle strength and explosive strength with age. Methods A total of 240 middle-aged men aged 45 years old were tested for muscle strength isometric muscle strength, including the maximum muscle strength and explosive force of left and right elbow joints, flexion and extension of left and right knee joints, and the maximum muscle strength of flexion and extension of left and right knee joints was measured by a self-developed digital isometric muscle contraction function detection system. At the same time, the data of limb morphology (including body mass, lean weight, upper arm and thigh circumference) were collected. The data of muscle strength collected by subjects of each age group were statistically analyzed, and the correlation between muscle strength and body shape indexes of subjects of corresponding age group was analyzed. Results the muscle strength of flexion and extensor muscle of knee joint decreased slowly year by year in middle-aged men over 45 years old, and the decreasing trend of muscle explosive force was the most obvious. The relationship between the maximum muscle strength of upper and lower extremities and body mass, fat removal body mass, upper and lower limb circumference and other body shape indexes was analyzed. The results showed that 45 鈮，
