STRONG Study: Prevention of Falls in Seniors at High Risk of Falling through Supplementation with Whey Protein and Strength Training
Descrizione riassuntiva dello studio
Possible risk factors contributing to sarcopenia include physical inactivity and inadequate protein intake (= protein supply). It is suspected that in seniors with insufficient protein intake, supplementation with whey protein positively affects the maintenance of muscle mass. (Whey protein is a protein (= protein) derived from whey (whey is known as the watery by-product in cheese production). The whey protein used in this study has a particularly high proportion of L-leucine – an essential amino acid (= vital building block for protein that the human body cannot produce itself), which likely plays a central role in energy metabolism in muscle tissue.) The main objective of this study is to investigate the effect of whey protein as a supplement with and without a strength training program on the frequency of falls in older adults at high risk of falling. We are also interested in the effect on muscle strength, muscle mass, mobility, physical performance, and quality of life. The effect will be tested over 12 months in a total of 800 women and men who are at least 75 years old, have experienced a fall with injury in the last 12 months, and have reduced protein intake. Allocation to groups is done randomly. Neither the participants nor the investigator know which group the participants have been assigned to.

Intervento studiato
The study tests four groups. Two groups receive a whey protein powder (2x23.7 g per day), the other two groups receive a comparator powder without whey protein (2x23.7 g per day). Of the respective two groups, one group receives a home strength training program (3x30 min per week) and the other group a home mobility training program (3x30 min per week). This means the four groups are composed as follows:
Group 1: Whey protein powder + strength training
Group 2: Comparator powder without whey protein + strength training
Group 3: Whey protein powder + mobility training
Group 4: Comparator powder without whey protein + mobility training

Malattie studiate
Sarcopenia, the excessive loss of muscle mass and muscle strength with increasing age, significantly contributes to the risk of falling and loss of autonomy in seniors.
(BASEC)
- 75 years old or older - meets at least one of the following five criteria: 1) weight loss of more than 4.5 kg in the last 12 months, 2) muscle weakness measured by handgrip strength, 3) exhaustion, 4) slow walking speed, 5) low physical performance and/or has experienced a fall with injury in the last 12 months - Reduced protein intake - Lives independently at home or with assistance at home (BASEC)
Criteri di esclusione
- Impairment of cognitive function - Cannot independently come to the study center - Cannot walk 3 meters without a walking aid - Severe renal dysfunction - Cannot follow the exercise program or take the powder - Diseases that impair walking function or increase the risk of falling (e.g., Parkinson's, hemiplegia) - Severe visual or hearing impairment - Insufficient German language skills to understand the instructions - Lives in a nursing or care home - Lives in the same household as another study participant (BASEC)
