简要总结
The primary aim of this study is to optimize the methodology to measure lower limb power in older adults, so that clinicians are able to detect functional problems in this population earlier.
详细描述
Aging is associated with slower movement patterns, a higher fall risk and a restriction in functionality. This will lead to an increase in the number of dependent elderly and a high socio-economic burden. From the age of 40, a systematic loss of muscle mass and muscle force, also known as sarcopenia, will occur. In addition, performing daily tasks requires the production of muscle force at a certain speed. The product of force and speed, power, decreases even earlier and faster than muscle force.
This power is typically measured with specialized equipment, which limits the large-scale applicability. With the help of accelerometry there is the possibility to measure power during more functional tasks and movements, which benefits the applicability, but the reliability, reference values and link with other outcome measurements related to sarcopenia has to be investigated.

结局指标
主要结局
Reliability of power measurements measured with a 3D accelerometer
时间窗: 1 test moment of approximately 30 minutes, planned between September 2019 and July 2020
Reliability of power measurements (watt) measured with a 3D accelerometer (DynaPort MoveTest, McRoberts) worn during functional activities (stair climbing, sit-to-stand test) three times within a period of 2 weeks
Rate of power (force-velocity) development
时间窗: 1 test moment of approximately 1 hour, planned between September 2019 and July 2020
Participants perform a test protocol on a Biodex Dynamometer. The rate of power development (watt/s) is defined as the linear slope of the power-time curve and is measured from the onset of movement till peak power.
Lower limb muscle power during a stair climb test
时间窗: 1 test moment of approximately 1 hour, planned between September 2019 and July 2020
The power (watt) needed to perform stair climbing is calculated using a 3D accelerometer (DynaPort MoveTest, McRoberts), worn at the back of the participant
Physical activity
时间窗: 1 week
Objective measurement of physical activity in a subgroup of older participants (n=50) by means of accelerometry
Number of steps/stairs a day
时间窗: 1 week
Objective measurement of physical activity in a subgroup of older participants (n=50) by means of accelerometry
Lower limb muscle power during a sit-to-stand test
时间窗: 1 test moment of approximately 1 hour, planned between September 2019 and July 2020
The power (watt) needed to perform 5 sit-to-stand transitions and a 30 sec. sit-to-stand test is calculated using a 3D accelerometer (DynaPort MoveTest, McRoberts), worn at the back of the participant
Handgrip strength
