一项纵向人体测量研究测量了 73 名退休男性的体脂和肌肉变化。在退休前和一年后再次进行的测量之间，身体脂肪增加了约 3%，身体肌肉减少了约 1%。在一个由 22 名男性组成的小组中，他们的肌肉下降幅度甚至更大，他们表示退休后活动量减少了；但在一个由 11 名男性组成的小组中，据说退休后活动量增加了，但他们的身体肌肉却有所增加。每年对 26 名男性的子样本进行五次测量（图 1）。体脂最初的增加被逆转，脂肪测量值显着回落至或低于退休前的值。然而，身体肌肉以最初的速度继续稳步下降，整个群体的大腿肌肉面积与体重的比率在退休时显着下降。讨论了衰老以及能量平衡和身体活动的变化对这些发现的可能贡献。
The changes in body fat and muscle in 73 men retiring from manual work have been measured in a longitudinal anthropometric study. Body fat increased by about 3% and body muscle decreased by about 1% between measurements made just before retirement and again 1 year later. The decline in muscle was even greater in a subgroup of 22 men who reported that their activity was less after retirement: but a subgroup of 11 whose activity was said to have been greater after retirement showed an increase in body muscle. A sub-sample of 26 men were measured on five further annual occasions (Fig. 1). The initial increase in body fat was reversed, and fat measurements fell back significantly to or below the pre-retirement values. Body muscle, however, continued to decline steadily at the initial rate, and the ratio of thigh muscle area to body mass fell significantly in retirement in the group as a whole. The possible contributions of ageing and of changes in energy balance and physical activity to these findings are discussed.
