Exercise with a whole food high protein diet provides older adults with a physical boost

New research from DCU has found that by combining strength and aerobic training with whole foods rich in protein as part of a balanced diet, can positively impact the physical health of older adults, specifically the strength and function of their legs.

The DCU study examined whether whole foods rich in protein, consumed on a daily basis, in parallel with aerobic and strength based exercises, could provide a physical benefit. The programme was undertaken by 56 adults aged 65 plus over a 12 week period. Researchers looked for impact on strength, physical function, the amount of fat and muscle and whether the exercise training took place with or without the dietary change.

Led by Dr Brendan Egan, DCU School of Health and Human Performance, it found that the mixture of aerobic and strength training improved strength and physical function in older adults. More importantly, an increase in daily protein intake, specifically from whole foods such as dairy, meat, fish and eggs, was beneficial for increasing their leg strength and muscle mass.

Overall, the research team noted that while aerobic and strength training were beneficial, there was an added advantage when combining all of this activity with an increase in protein, from whole food sources and when consumed daily.

The latest findings from DCU will be of particular interest to clinicians working in the field of exercise prescription, rehabilitation and nutritional care of older adults.
