Abstract

Four months physical training significantly raised the mean proportions (%) of lauric (+0.64), myristic (+0.52), stearic (+2.06) and linoleic (+1.69) acids and lowered the mean proportions of palmitic (-1.46) and oleic (-3.46) acids in adipose tissue of 20 apparently normal men aged 20-55 yr. These changes were dependent on pretraining proportions of the fatty acids. In addition, the decreases in palmitic acid and oleic acid proportions were positively correlated (rho = 0.905, P less than 0.01, tau = 0.758, P less than 0.01). The pattern of significant correlations among adipose tissue fatty acids was altered as a result of training. We suggest that preferential mobilisation of fatty acids from adipose tissue is responsible for the change in adipose tissue fatty acid composition with increased physical training. The significant increase in adipose tissue linoleic acid proportions may be linked with the reduced risk of coronary heart disease which has been previously associated with increased physical activity.

摘要

四个月的体育锻炼显著提高了20名年龄在20 - 55岁的明显健康男性脂肪组织中月桂酸（+0.64）、肉豆蔻酸（+0.52）、硬脂酸（+2.06）和亚油酸（+1.69）的平均比例（%），并降低了棕榈酸（-1.46）和油酸（-3.46）的平均比例。这些变化取决于训练前脂肪酸的比例。此外，棕榈酸和油酸比例的降低呈正相关（rho = 0.905，P < 0.01，tau = 0.758，P < 0.01）。训练导致脂肪组织脂肪酸之间显著的相关模式发生改变。我们认为，随着体育锻炼增加，脂肪组织中脂肪酸的优先动员是脂肪组织脂肪酸组成变化的原因。脂肪组织中亚油酸比例的显著增加可能与冠心病风险降低有关，而这之前已与身体活动增加相关联。
