“…To verify the proposed hypothesis, it is necessary to take measurements related to leg muscle strength, leg muscle explosive power, reaction speed and side kick ability (Bui et al, 2019;Fiske et al, 2007). So, to get information about the effect of the variables proposed specifically for the Tarung Drajat sport, the data collected in this study are primary data taken from test respondents.…”

The aim of this study was to examine the impact of leg muscle strength and leg muscle explosive power on Tarung Derajat side kick ability through reaction speed. This study enhances the existing literature regarding the effect of leg muscle strength and leg muscle power on the side-kick ability of Tarung Derajat and includes reaction speed (simple and total), which is often trained to determine the level of performance in martial arts. In this study, subjects were randomly assigned n = 60 people to the test to see the ability of each of the proposed variables. Next, to examine the model structure effect of this study, we made use of IBM SPSS software. The results showed that leg muscle strength, leg muscle explosive power, and reaction speed had a significant impact on the ability of the Tarung Derajat side kick both directly, indirectly and totally. These results illustrate the important role of the direct influence of the yield power of the leg muscles which have a major influence on the side kick abilities of Tarung Derajat athletes. The implications for practitioners and researchers are discussed in detail.

“…Previous studies showed that older subjects had lower maximal strength, slower force production, and more force variability compared with young subjects 9 , 10 . Moreover, muscle power is gaining consideration as an outcome measure of muscle function in COPD due to its strong association with mobility and function 8 , 11 . However, there is a lack of knowledge about the same muscle properties in COPD, whereas their change in response to a conventional pulmonary rehabilitation (PR) program may clarify the skeletal muscle dysfunction in COPD, thus improving the design and individualization of the exercise intervention.…”

This study aimed to measure changes in different properties of skeletal muscles and evaluate their contribution and relationship to changes in functional performance after pulmonary rehabilitation (PR) in patients with chronic obstructive pulmonary disease (COPD). COPD outpatients attending 5 weeks of conventional PR were recruited. Functional performance [5-repetitions sit-to-stand (5STS), and 4-m gait speed (4mGS)], and muscle function (maximal isometric strength, power, force control, and relative concentric and eccentric activation during 5STS) were assessed after PR and 3 months of follow-up. Twenty patients (71 years; 52% of predicted FEV1) completed the study. 4mGS and relative concentric activation during 5STS decreased respectively by 7.7% and 26% between the beginning of PR and follow-up. Quadriceps strength, power, and force control improved by 10.4%, 27.3%, and 15.2%, respectively, from the beginning of PR to follow-up the relative eccentric activation during 5STS explained 31% of the variance in 4mGS changes. In conclusion, functional performance appeared to decline after conventional PR, whereas several properties of skeletal muscles were maintained at follow-up in COPD outpatients. Of note, eccentric contractions might play a role in the improvement of functional performance. Therefore, future studies with interventional design should include eccentric training in PR programs during clinical COPD practice.

“…Moreover, RT is not limited to muscle strength exercises but refers to further trainable muscle characteristics, such as muscle power and local muscle endurance [6]. Indeed, there is evidence that all these muscle characteristics contribute to enhancing the overall function of peripheral muscles in individuals with COPD, inducing structural and metabolic adaptations and improving the patient's functional exercise capacity [7,8].…”

Isolated Resistance Training Programs to Improve Peripheral Muscle Function in Outpatients with Chronic Obstructive Pulmonary Diseases: A Systematic Review

et al. 2021

This systematic review aims to establish which isolated resistance training (RT) programs have been used in outpatients with chronic obstructive pulmonary disease (COPD) and their impact on all aspects of peripheral skeletal muscle function. Electronic databases were systematically searched up to June 2021. The eligibility criteria were: (1) randomized controlled trials investigating the effects of supervised and isolated RT programs in outpatients with COPD and (2) RT programs lasting 8–12 weeks, (3) including at least one outcome measure related to trainable muscle characteristics. Initially, 6576 studies were identified, whereas 15 trials met the inclusion criteria. All the included trials reported that isolated RT improved both upper and lower limbs’ maximal strength. Muscle endurance and power also increased after RT but received less attention in the analysis. Furthermore, few studies assessed the effect of RT on muscle mass and cross-sectional area, reporting only limited improvement. Isolated RT programs carried out 2–3 days a week for 8–12 weeks improved skeletal muscle function in individuals with COPD. The RT program should be specifically focused to the trainable muscle characteristic to be improved. For this reason, we further encourage the introduction of a detailed assessment of muscle function and structure during the pulmonary rehabilitation practice.
