In this study we have investigated the relationship between hypertrophy of skeletal muscle byexercise and fasting to examine the relationship between exercise and nutrition. The animalused in the experiment were retired female mice. Exercise was carried out by tenotomymethod. Groups were divided into four groups with five animals in each group. After theseventh day, groups of mice that ate a diet were fed for 6 days were bled under anesthesia, andwere sacrificed. Each plantaris muscle and the soleus muscle, liver, spleen, kidney, heart wereremoved; after that, each weight was measured by the electromagnetic scale. The no-foodgroup began fasting the day after the start of resistance training. After five days, mice weresacrificed in a similar manner; the weight of the organs was measured in a similar manner. Inthis experiment, the following findings were revealed. Muscle weight increased by resistancetraining without the influence of the presence or absence of the meal. Hypertrophy rate waslower in plantaris muscle compared with the soleus muscle. When the meal has been ingested,resistance exercise has been found to affect the heart weight. Regardless of diet, exerciseresistance is the average value; statistical difference was not observed. When resistanceexercise was performed, the weight of kidney in diet group showed lower values compared tothe no food group. Further, even if resistance exercise was not performed, the food groupshowed a statistically significantly lower value compared to the no food group. The weight ofthe spleen, regardless of the presence or absence of the resistance exercise, showed a low valuewithout meals. The weight of liver was not observed the effect of the resistance exercise andof the diet.In this study we have investigated the relationship between hypertrophy of skeletal muscle byexercise and fasting to examine the relationship between exercise and nutrition.
