Seniors who take fish oil supplements react better to strength training
Women in their mid-sixties get more out of strength training if they take fish-oil supplements, discovered Brazilian researchers at Parana Federal University. They did an experiment with 45 women aged 64.
The Brazilians wanted to know whether fish oil could help healthy elderly people with their strength training. Strength training is an effective anti-aging medicine, but the older people get, the less well their bodies react to this form of exercise. That was the reason the Brazilians carried out their experiment.
The maximal strength the subjects were capable of developing during their exercises – their peak torque – increased more in the groups that took fish oil than in the ST group. Supplementation also had a similar effect on the electro-mechanical delay [EMD]. This is the time that elapses between a muscle being stimulated by a nerve and when it contracts. The time elapse decreased by more in the fish-oil groups.
At the end of the 12 weeks the researchers tested the extent to which the women were better able to perform daily movements, for example how often they could get up out of a chair repeatedly [Chair rising]. Again, the fish-oil groups had better results than the group that had only done training.
"Fish oil may be an attractive supplement for the elderly to maximize their neuromuscular responses to strength training, which is important to life quality", the Brazilians conclude. "However, the supplementation length does not influence the strength-training effects."
