[fish oil + strength training for the elderly]…….
“Age-related decline in lower limb explosive strength leads to impaired ability to perform daily living tasks. The present randomized controlled trial demonstrates that a healthy diet rich in n-3 polyunsaturated fatty acid enhances resistance training-induced gains in dynamic explosive strength capacity during isolated lower limb movements and multijoint exercises in healthy elderly women.”
“This supports the use of strategies combining resistance training and dietary changes to mitigate the decline in explosive strength capacity in older adults.”

“The effects of 24 week of resistance training combined with a healthy diet on lower limb explosive strength capacity were investigated in a population of healthy elderly women.”

“Progressive resistance training was performed at a load of 75–85% one-repetition maximum.”

“In conclusion, a healthy diet rich in n-3 polyunsaturated fatty acid can optimize the effects of resistance training on dynamic explosive strength capacity during isolated lower limb movements and multijoint exercises in healthy elderly women.”

“This study examined whether home-based, high-speed calf-raise training changes the rate of torque development during plantar flexion contractions and balance performance in elderly men.”

“The subjects in the training group completed 8 week (3 times/week) of home-based bilateral calf-raise training using body mass.”

“Our findings indicate that calf-raise training at home, performed without special equipment or venue, induces a substantial increase in the plantar flexors’ rapid force-generating capability and triceps surae activations.
