Background
sarcopenia, muscle loss
SARCOPENIA
Skeletal muscles support physical activity and act as a major metabolic organ. In athletics, increased muscle strength and mass are important factors that improve performance. Age-related muscle loss and decreased strength, referred to as sarcopenia, have been recognized as major risk factors and may necessitate nursing care in aged individuals. As a counter-intervention, resistance exercise training has been recommended to improve athletic performance and prevent sarcopenia in older adults [Adequate dietary nutrition is necessary for muscle adaptation to training. Sufficient protein intake is required to supply amino acids as substrates for protein synthesis. The timing of protein intake and complementary consumption of carbohydrates effectively activate protein anabolism [Tea beverages, which are consumed daily, are sources of bioactive micro-compounds. Green tea contains high concentrations of catechins and reportedly has various health benefits. Daily intake of green tea is beneficial for neural, cardiovascular, and metabolic functions in humans [
