Physical training and adipose tissue fatty acid composition in men.
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.
