2025-08-27T10:06:51+07:00

Purpose
The purpose of this study was to examine the effects of supplementary power yoga training on leg muscle power and agility in female university futsal players.

Methods
Twenty-eight female university futsal players were randomly assigned to either an experimental group (n = 14) or a control group (n = 14). The control group performed regular futsal training three times per week, while the experimental group performed the same futsal training in addition to supplementary power yoga training twice per week for six weeks. Agility was assessed using the Illinois Agility Test, whereas muscle strength and muscle power were evaluated using an isokinetic dynamometer at 60°/s angular velocities and 180°/s angular velocities. Data were analyzed using means and standard deviations. Independent t-tests and Mann–Whitney U tests were applied for between-group comparisons, and paired t-tests were used for within-group comparisons. Statistical significance was set at p < .05

Results
At baseline, no significant differences were observed between the control and experimental groups in muscle strength (extension and flexion), muscle power (extension and flexion), or agility, indicating that both groups had comparable physical performance prior to the intervention. After six weeks of training, the experimental group demonstrated greater improvements than the control group across all variables, including muscle strength (extension and flexion), muscle power (extension and flexion), and agility. Post-test analyses confirmed that the experimental group achieved significantly higher values than the control group at the p < .05 level.

Conclusion
The findings support that supplementary power yoga training can effectively enhance muscle strength, muscle power, and agility. Therefore, it may be considered a beneficial alternative method for improving muscular power and agility among university female futsal players and can potentially be applied to athletes in other sports as well.

2025-06-20T15:09:19+07:00

Purpose
This study aimed to examine the physiological responses before and after competition in Ju-Jitsu fighting male -62 kg. weight category.

Methods
The participants were eight male Ju-Jitsu Player aged 18–24 years, holding at least a brown belt, and competing in the -62 kg. category. They were purposively selected based on accumulated scores from five official competitions sanctioned by the Ju-Jitsu Association of Thailand. The player participated in five rounds of matches, from preliminary to final, totaling 16 matches. Physical fitness was assessed two days before the competition. Physiological responses—heart rate (HR), blood lactate concentration (BLC), and Peripheral oxygen saturation (SpO2). The differences between pre- and post-competition measurements (HR and BLC) were analyzed using the Paired Sample t-test. If the data were not normally distributed, the Wilcoxon Signed-Rank Test was employed (SpO2). The differences between winners and losers were analyzed using the Independent Sample t-test (HR and BLC). In cases where the data were not normally distributed, the Mann–Whitney U Test was used (SpO2). Statistical significance was set at p < 0.05.

Results
There were statistically significant differences (p < 0.05) in HR, BLC, and SpO2 before and after competition. HR increased by 57.46%, BLC by 92.48%, and SpO2 by 1.50%. When analyzed by match outcome, significant changes (p < 0.05) in all three variables were found in winners, while losers showed significant changes only in HR and BLC levels. No statistically significant differences were observed between winners and losers in any physiological variable before or after competition. However, winners demonstrated superior physical fitness in all aspects, handgrip strength, leg power, and upper- and lower-body muscular strength.

Conclusion
After the competition, Ju-Jitsu Players showed increased HR and BLC, while SpO2 decreased. This indicates that Ju-Jitsu is a high-intensity sport that relies heavily on anaerobic energy systems and rapid recovery ability. No significant physiological differences were observed between winners and losers, suggesting that both groups exerted maximal physical effort. Therefore, training should focus on enhancing recovery systems and improving lactate clearance to maintain performance in subsequent rounds of competition.

Purpose
To study the knowledge, attitude, and practice of physical activities in Thai monks and to compare the knowledge, attitude, and practice of physical activities in Thai monks according to the demographic characteristics (highest level of education, location of temple)

Methods
This study was survey research. The sample group consisted of 500 monks in Thailand, selected using a multi-stage random sampling method. Data was collected via a researcher-developed questionnaire. The statistical analysis included frequency, percentage, mean, and standard deviations, and analyzed the variance (one-way ANOVA) at a statistical significance level of 0.05 to analyze the differences in means of knowledge, attitudes, and physical activity practices of Thai monks according to demographic characteristics.

Results
The monks had moderate knowledge (xˉ = 5.23, S.D. = 0.96). The attitude was at a good level. (xˉ = 3.16, S.D. = 0.38) and moderate physical activity (xˉ = 3.00, S.D. = 0.52). Monks with different levels of education had significantly different attitudes and practices of physical activities at a statistical significance of 0.05. Additionally, monks residing in different locations had significantly different attitudes and practices of physical activities at a statistical significance of 0.05.

Conclusion
Thai monks demonstrated a moderate level of knowledge, a good level of attitude, and a moderate level of engagement in physical activity. While there were no statistically significant differences in knowledge of physical activity among monks with different education levels or residing in different locations (p > 0.05), there were statistically significant differences in their attitudes toward and practices of physical activity (p < 0.05).

2025-07-13T09:26:48+07:00

Thailand is entering a fully aged society, resulting in an increasing emphasis on the role of sports as a tool for enhancing the well-being of older adults. This academic article aims to 1) analyze fundamental concepts and theories related to sports competitions for older adults within the contexts of active aging and successful aging; 2) synthesize a new conceptual model of sports competitions that promotes well-being, safety, and sustainability for the aging population; and 3) propose practical approaches and policy measures to advance senior sports competitions in accordance with the 7th National Sports Development Plan and the Thai social context. The study employs a systematic narrative literature review combined with analytical synthesis. The findings indicate that the concepts of active aging and successful aging can systematically explain the connections among motivation, participation, and the design of competitions tailored to the capabilities of older adults. The IWOCM (Integrated Wellness-Oriented Competition Model) was developed to propose essential elements of competitions that prioritize safety, diversity of activity formats, and the involvement of families, communities, and relevant sectors. Additionally, the article presents policy recommendations to support infrastructure development, human resource enhancement, and integration of plans at both national and local levels, with the aim of elevating senior sports competitions as a sustainable and meaningful mechanism for promoting well-being in Thai society. This framework serves as a foundation for the long-term development of academic knowledge in the field of recreational studies for older adults.
