A research group led by Associate Professor Kohei Watanabe of the Faculty of International Liberal Arts, Chukyo University has succeeded in trying to regulate the effect of strength training on elderly people with food.
The research was conducted in collaboration with Chukyo University, Maribol University (Slovenia), Sugiyama Jogakuen University, Kyoto University, Nippon Fisheries Co., Ltd., and Kyoto Sangyo University.
This time, we conducted an 20-week strength training for 8 elderly people and investigated the results of ingesting different foods.Participants were divided into half and were given daily intake of fish protein (5 g) and casein (5 g), respectively, and their maximum muscle strength, muscle mass, and neural activity were evaluated in detail every two weeks.Nerve activity was recorded and analyzed using a special method called multi-channel surface myocardography.
As a result of the investigation, after 8 weeks, the maximum muscle strength increased similarly in both groups, but the muscle mass increased only in the fish protein group.In addition, although changes in neural activity were significantly observed in the control group, no significant changes were observed in the fish protein group.
From this, it is possible that the functions of muscle and nerve activity can be selectively changed during strength training depending on whether or not foods that have some effect such as hypertrophy of muscles (fish protein in this study) are ingested. Found.
In the future, the research group says that even if the training is the same, it is possible to change the food to be ingested depending on whether you want to train muscles or nerves.
