NCT03842579

Brief Summary

The purpose of this study is to determine the effects of interventions with high-protein diet alone or in combination with resistance training on muscle mechanical function (muscle power and strength), frailty status, functional performance, muscle mass and quality of life.

Study Arms (3)

Exercise and Protein (EXEPROT)

EXPERIMENTAL

Participants in EXEPROT receive: a high-protein diet combined with Resistance training. The high-protein diet is based on milk-based protein-rich products to supplement the habitual diet (corresponding to a protein intake of 1.5 g/kg/day). 4-day food records are used to estimate the needed protein. Of the shelf-products (e.g. milk, cheese) are used considering the individually preferences. Products are delivered once a week. The training intervention includes progressive explosive type heavy-resistance training two times per week. The intervention runs for 16 weeks. Adherence to the training protocol is monitored at each session. Adherence with the nutrition protocol is monitored daily plus at phone follow-ups where participants are asked about e.g. appetite, weight, habitual intake.

Other: Resistance trainingOther: High-protein diet

Protein-only (PROT)

ACTIVE COMPARATOR

Participants in PROT-group receive the nutritional intervention: The high-protein diet. The diet is based on daily milk-based protein-rich products to supplement the habitual diet (corresponding to a total protein intake of 1.5 g/kg/day). The needed amount of protein supplementation is estimated from 4-day food records. Of the shelf-products (e.g. milk, skyr, cheeses) are used considering the individually preferences. Products will be delivered once a week at the home of the participant. The intervention runs for 16 weeks. Adherence with the nutrition protocol is monitored daily (registration of compliance with the dietary plan) as well as at phone follow-ups where participants are asked about e.g. changes in appetite, weight, and habitual intake.

Other: High-protein diet

Recommendations (REC)

ACTIVE COMPARATOR

Participants in the REC-Group receive the comparative intervention: Recommendations. The official national dietary recommendations for adults \>65 years, developed by the Ministry of Environment and Food of Denmark, and related materials is given to the participants and they are encouraged to follow the guidelines (recommending a protein intake of 1.0-1.3 g/kg/day). The intervention runs for 16 weeks. During the intervention all groups will receive two seminars on specific topics related to healthy ageing (e.g. talks on physical activity, sedentary behaviour, and nutrition).
