Summary
Regular exercise in older adults may preserve grip force control. Even those over 76 showed no deficits, suggesting physical activity delays age-related grip changes.
Area of Science:
- Gerontology
- Motor Control
- Exercise Physiology
Background:
- Age-related decline in grip force control is a concern.
- The impact of regular physical activity on this decline is not well understood.
Purpose of the Study:
- To investigate age-related grip force control in physically active adults.
- To compare grip control between young adults and older active adults.
Main Methods:
- Grip force and object acceleration were measured during a grasp-lift task.
- Participants included physically active adults (50+) and young adults (18-30).
- Daily physical activity levels were assessed.
Main Results:
- No significant differences in grip force control were found between age groups.
- Adults over 76 exhibited stronger grip force and increased latency.
- Physical activity levels did not differ across age groups.
Conclusions:
- Regular exercise may mitigate or postpone grip force control deficits in aging.
- Physically active older adults maintain grip control comparable to younger individuals.
