Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
1. To examine the distribution and contractile properties (cross-sectional area, maximal force, specific force, maximal shortening velocity) of single muscle fiber sex/Myosin heavy chain (MHC) type-related differences, by extracting a single muscle fiber from the vastus lateralis in young men and women.
2. To examine the effects of intramyocellular lipids on physical activity ability, muscle dysfunction, and metabolic disorders in relation to aging and obesity.
3. To examine the effects of intramyocellular lipids on physical activity ability, muscular dysfunction, and metabolic disorders after 12 weeks resistance exercise intervention.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Young men
Range of age is 20-35 years, young men (BMI 19-23 Kg/m2) They did not suffer from musculoskeletal or metabolic diseases, and had not performed regular exercise within the previous 3 months.
No interventions assigned to this group
Young women
Range of age is 20-35 years, young women (BMI 19-23 Kg/m2) They did not suffer from musculoskeletal or metabolic diseases, and had not performed regular exercise within the previous 3 months.
No interventions assigned to this group
Elderly women (control)
Range of age is 65-80 years, Elderly women (BMI 19-23 Kg/m2) They did not suffer from musculoskeletal or metabolic diseases, and had not performed regular exercise within the previous 3 months.
Resistance exercise with a gym stick
Exercise intervention: The resistance exercise intervention is performed with a gym stick for 3 times a week for 12 weeks. Exercise load is gradually increased by the number of times the band is wound and the speed of motion by dividing into three stages in 1-4 weeks (1st stage), 5-8 weeks (2nd stage) and 9-12 weeks (3rd stage).
Elderly obese women
Range of age is 65-80 years,Elderly obese women (BMI ≥25 Kg/m2) They did not suffer from musculoskeletal or metabolic diseases, and had not performed regular exercise within the previous 3 months.
Resistance exercise with a gym stick
Exercise intervention: The resistance exercise intervention is performed with a gym stick for 3 times a week for 12 weeks. Exercise load is gradually increased by the number of times the band is wound and the speed of motion by dividing into three stages in 1-4 weeks (1st stage), 5-8 weeks (2nd stage) and 9-12 weeks (3rd stage).
