User:B17rad/Neuromuscular function in aging adults

With aging, older adults display a decline in cognitive ability, decrease in neuromuscular function, and higher rates of sarcopenia, age related muscle mass decline. Research has been conducted to determine the best options to slow the age-related decline in cognitive function as well as the loss of muscle mass. Results say the best way to go about it is to have consistent physical activity as well as a healthy diet.

Older adults participated in Yuishinkai Karate training across a five-week study showing that there was an increase in grip strength as well as plantar flexion, which improves older adults’ ability to walk. Multiple participants also saw decreased reaction times to certain stimuli. In a practical sense, older adults who continue to train in karate will see a decreased risk for severe falls. This increase in neuromuscular function can be attributed to increased spinal cord excitability, leading to better communication in the nervous system. Advanced growth has been shown in participants with Parkinson’s disease. This study also identified a dose effect. Continued engagement and keeping a routine of physical activity is key to sustaining neuromuscular function.

While karate training seems more focused on physiological improvements, it can also be a way to increase cognitive function as well. Another study was conducted across twelve weeks to determine the effects of motor based cognitive activities. Older adults with motor cognitive impairments interacted with exercises such as puzzles, brain teasers, and musical dance routines to try and link physical activity with cognitive performance. Researchers found that these activities can slow the onset of Alzheimer’s disease. The activities also showed an increase in recognition of visuospatial cues as well as naming and delayed recall. Associated with motor abilities, the researchers found that sustained activity in a routine is most beneficial to those older adults, meaning, the improvements started to decline with inactivity.

Previously mentioned tasks were shown to slow the decline of neuromuscular function and loss of muscle mass, but having a healthy diet can prevent sarcopenia. A meta-analysis found that protein supplementation can help slow sarcopenia. Through this analysis, participants were supplemented with whey protein because of its’ fast-absorbing nature. They saw increased muscle mass on the appendicular muscle groups. Protein supplementation as well as physical activity and cognitive exercise can help stunt sarcopenia and improve neuromuscular function.

Older adults often see loss of muscle mass as well as decline in neuromuscular function and cognitive ability. Through physical activity and motor based cognitive exercises, older adults can reduce the risk of falling, sarcopenia, and improve their overall well-being and satisfaction with their lives. Of course, individuality comes into play. Successful techniques differ from person to person. Consistency is key as well as implementation into a sustainable routine.
