Outline of Final Research Achievements |
The results of the three years research were as follows. (1) Middle-aged and older recreational cyclists that train approximately three days a week had comparable quadriceps muscle size and maximal oxygen uptake. (2) Twenty minutes cycling exercise at an exercise intensity equivalent to lactate threshold activated the muscle hypertrophy related intracellular signaling pathways in young men. (3) Maximal oxygen uptake and quadriceps muscle size increased by 6 weeks of 30 minutes cycling exercise, which performed at a perceived exertion of somewhat hard, 2 days per week. Therefore, 20-30 minutes cycling exercise at a perceived exertion of somewhat hard (an exercise intensity equivalent to lactate threshold), 2-3 days per week, can concurrently increase maximal oxygen uptake and quadriceps muscle size.
