Mobility coach Dana Santas is teaching a tennis ball technique to help people improve their reaction time [1, 2].
Maintaining quick reflexes is critical for older adults because it can reduce the risk of injuries from falls and protect the brain [1, 2]. As the body ages, the ability to react to sudden changes in environment often declines, increasing the likelihood of accidents.
Santas demonstrates a simple exercise using a tennis ball to sharpen these responses [1, 2]. The method focuses on the coordination between visual stimuli and physical movement. By practicing these rapid reactions, individuals can train their nervous system to respond more efficiently to unexpected trips or slips.
This type of mobility training aims to build a safety buffer for the body. Improving reaction time does not just prevent the initial fall, but can also help a person recover their balance more quickly during a stumble [1, 2]. This capability is often the difference between a minor trip and a serious injury.
Santas said such exercises are accessible tools for longevity. Because the technique requires only a tennis ball, it can be integrated into daily routines without the need for expensive gym equipment or specialized facilities [1, 2].
Consistent practice of these drills helps maintain the connection between the brain and the muscles. This neurological maintenance is a key component of overall mobility and independence in later life [1, 2].
“Improving reaction time can reduce the risk of injuries from falls and protect the brain.”
The focus on reaction-time training reflects a growing emphasis on 'preventative mobility' in aging populations. Rather than treating the consequences of a fall, these exercises target the neurological speed required to avoid the fall entirely, potentially reducing the burden on healthcare systems associated with geriatric trauma.
