Effect of Muscle Strength Training and Muscle Endurance Training on Muscle Deoxygenation Level and Endurance Performance

Abstract

Abstract.[Purpose] The purpose of this study was to compare the effects of muscle strength training and muscle endurance training on muscle deoxygenation level and endurance performance. [Subjects and Methods] Nineteen healthy young men were randomly assigned to a muscle strength training (STR: n = 6) group, muscle endurance training (END: n = 6) group, or a control (CON: n = 7) group. The training intensity for STR was 60°/sec × 10 repetitions × 5 sets/day and that for END was 240°/sec × 50% fatigue repetitions × 2 sets/day, 3 days/week, for 6 weeks. All subjects performed cardiopulmonary exercise testing (CPX) to measure maximum oxygen uptake, exercise time and muscle deoxygenation level of vastus lateralis, and underwent muscle strength and muscle endurance measurements pre-and post-training. [Results] In the STR group, muscle strength tended to increase, while muscle endurance significantly increased in the END group. Muscle deoxygenation level was significantly increased in both training groups. Maximum oxygen uptake did not change; however, in the END group alone, exercise time was significantly prolonged.[Conclusion] These results suggest that muscle endurance training is more effective at increasing endurance performance than muscle strength training.

Improvements in tissue blood flow and lumbopelvic stability after lumbopelvic core stabilization training in patients with chronic non-specific low back pain

“…One of the interesting findings in the current study is that both LPS and TBF increase after LPST. Exercise training reportedly increases skeletal muscle oxygenation by increasing the capillary network, improves adenosine triphosphate production, and decreases lactic acid production in the muscles and blood 23 ) . Therefore, improved TBF over the lumbopelvic muscles may have resulted in improved low back pain condition and LPS and vice versa.…”

The effects of bodyweight-based exercise with blood flow restriction on isokinetic knee muscular function and thigh circumference in college students

“…An isokinetic knee muscular function test was performed using a HUMAC NORM System (Cybex 770-NORM ® , Cybex International, Medway, MA, USA), and it measured muscular strength and power. The test protocol was based on those of the previous studies 14 , 15 ) . The extensor and flexor of the both knee joints were evaluated 10 times each at 60°/sec (muscular strength) and 15 times each at 180°/sec (muscular power), and the peak torque/body weight (%) was calculated from the results.…”

Electrically stimulated ventilation feedback improves the ventilation pattern in patients with COPD

“…Finally, COPD, which has an increasing incidence in the population, has a high prevalence in the elderly 4 ) , and the relationship between COPD and decreased cognitive function has been recently reported 22 , 23 , 24 ) . The development of new rehabilitation methods is urgently needed to delay the progression of cognitive impairment in patients with COPD.…”

“…Exercise therapy is at the core of rehabilitation for chronic obstructive pulmonary disease (COPD) 1 , 2 , 3 ) , the incidence of which continues to increase worldwide 4 , 5 , 6 ) . Both endurance and strength training focusing on the lower limbs can decrease the lactic acid concentration in the blood, carbon dioxide production, and minute ventilation.…”
