This systematic review highlights the effects of dairy products on muscle mass , muscle strength and body performance in the elderly population in the perspective of Ca , P , vitamin D and protein
The risk of sarcopenia increases with aging .
Malnutrition in the elderly population is an important risk factor for sarcopenia .
Calcium ( Ca ) , phosphate ( P ) , vitamin D and protein are key nutrients for the human body and affect muscle mass and quality .
Dairy products are rich in these nutrients , which implicates that dairy products might be ideal for elderly population .
Similar effects of leucine rich and regular dairy products on muscle mass and functions of older polymyalgia rheumatica patients: A randomized crossover trial
Objectives Leucine-rich milk and whey proteins have been suggested for prevention of age related loss of muscle mass and strength i.e. sarcopenia . The effects of milk protein supplementation and low intensity home based physical exercise on body composition and muscle functions were investigated . Design A r and omized double blind crossover trial . Setting Community dwelling members of Helsinki rheumatoid association . Participants Older people ( N = 47 , mean age 69.5 years ) suffering from polymyalgia rheumatica . Intervention Patients performed as many st and ups as possible twice a day after which they ingested a regular ( Control ) or a whey protein enriched dairy product with high leucine content ( Test ) . The 8-week intervention periods were separated by a 4-week wash-out . Measurements Body composition was measured by dual x-ray absorptiometry and muscle functions by h and grip strength , force platform countermovement jump performance , chair st and test , and walking speed . Results The 16-week home-based post-exercise supplementation result ed in a 1.8 % increase ( p = 0.052 ) in lower limb muscle mass . Walking speed ( + 5.3 % , p = 0.007 ) and chair st and test performance ( −12.2 % , p < 0.001 ) were also improved . Furthermore , a tendency for increased jump power ( + 3.0 % , p = 0.084 ) was observed . However , significant and consistent differences were not found in the changes of muscle mass indices or muscle functions between supplements , but the test supplement tended to prevent accumulation of body fat . Conclusion A low intensity home based exercise program combined with post-exercise milk protein supplementation is feasible despite some gastrointestinal complaints and seems effective in improving the muscle mass and functions of older persons with a inflammatory disease . Further studies are needed to establish , whether and to what extent the use of leucine-enriched whey products prevent or treat age-associated sarcopenia and whether they are superior to the present commercial milk products
