We investigated the effects of an acute bout of exercise on serum soluble leptin receptor (sOB-R) concentrations. Eighteen male participants completed two different exercise sessions with intensities of 25% and 65% maximal aerobic capacity (VO2max). In addition to the energy expenditure during exercise sessions being measured, blood samples were collected before exercise, and immediately, at 24 h, and at 48 h post-exercise to analyse sOB-R, leptin and insulin levels. At 24 h post-exercise, sOB-R and leptin concentrations at the 65% VO2max were significantly different from those at the 25% VO2max. Leptin levels at 48 h post-exercise were also significantly lower for the 65% VO2max than for the 25% VO2max (P < 0.01). In the 65% VO2max session, the energy expenditure during exercise was significantly associated with leptin concentrations at 24 h and 48 h and sOB-R concentrations at 24 h post-exercise. However, no correlations were found between sOB-R and leptin at the three post-exercise time points. In conclusion, an acute bout of exercise with 920 kcal of output resulted in an increase in sOB-R levels at 24 h post-exercise. However, the changes in sOB-R levels due to an acute bout of exercise might not contribute to the delayed decrease observed for leptin.
Basketball game is decided by the most point counted from successful shooting. Moreover, free throw is one of many shooting techniques which is frequently used in basketball game. So, the aims of this research are reviewing the ball trajectory direction to find the formula to increase possibility of successful shooting and decrease shooting error possibility. This is a quantitative study with independent t-test data analysis by SPSS. There are 73 male college physical education students(age : 20 1.2 years) who were categorized based on their height in to 5 groups. Each of them tried to make 3 successful free throw. The result, there are significant different of ball direction, launching angle, maximum elevation, and ball velocity among different height group (< 0.05). In the conclusion, the launching angle and maximum elevation among different height group has different characteristic. However, the ball direction and velocity have more similarities among different height group.
This study aims to evaluate university students' daily activities and the effect of physical activity on physical fitness, especially during the COVID-19 pandemic. This research used comparative and correlational research methods. Thirty research samples consisted of 13 junior year university students and 17 senior year university students were selected by the purposive sampling method. Every student was monitored for their daily activities for one week and categorized into sports, college, organization, and other activities. Physical fitness was measured using the MFT test to measure the VO 2 Max in ml/kg/min units. The data analysis results showed no significant difference between junior and senior semester students in VO 2 Max, physical exercise, organizational activities, lecture activities, sleeping, and other activities. There was a significant difference in VO 2 Max and physical exercises (sig < 0.05) between genders. Male students spent more time exercising (17.87 ± 11.1) than female students (10.80 ± 6.04). Furthermore, male students had a higher average VO 2 Max (42.38 ± 7.53) than female students (29.36 ± 6.07). Based on the regression analysis results, there is a significant value between physical exercises and sleeping toward VO 2 Max capacity (sig. < 0.05).
Whether cardiorespiratory fitness (CRF) and physical fitness affect academic performance in college first-year students is a concerning issue. Therefore, the goal of this study was to examine the relationship between academic performance and CRF and the components of physical fitness in college first-year students. A total of 98 college first-year students (female: 30, male: 68) participated in this study. The CRF was measured using a gas analyzer on a treadmill and physical fitness included body mass index, sit-up in one minute, standing long jump, sit-and-reach, 800 (female) and 1600-m (male) run/walk. The two assessments were scheduled by an interval of 7-10 days. The grade point average (GPA) in formal grade report was provided by each participant after the completion of the first academic year. The data were analyzed by an independent t-test and the relationships between variables were analyzed by Pearson product-moment correlation. The results displayed that males were significantly higher than females in CRF (p < 0.05). For physical fitness, the BMI, sit-up in one minute, standing long jump were significantly higher in males than in females. However, females were significantly higher than males in the number of sit-and-reach (p < 0.05). For academic performance, the GPA displayed similar between different genders. After regression analyses, the CRF was significantly related with academic performance and explained 56% of the variance for GPA in male college freshmen. However, neither CRF nor the components of physical fitness showed any significant relationship with academic performance in females. In conclusion, the CRF accounted for the variance of academic performance in male. However, a similar result was not found in the female part.
Fundamental movements are part of teaching objectives in the physical education curriculum for elementary schools students. This study aimed to analyze the elementary school students' basic movement skills (FMS) using the kinematic approach. The fundamental movements in this research were correlated with lower body parts, i.e., one leg standing position with closed eyes (non-locomotor), hopping (locomotor), running (locomotor), and kicking (manipulative). This was comparative research that was conducted in a quantitative approach. The random sampling method selected 126 elementary students (75 male and 51 female) aged 8.96 ± 1.50 years old. The kinematic data were collected by using kinematic video analysis in Kinovea 0.9.4 computer software. The independent variables were one leg standing position in second, distance per step (DPS) in centimeter, speed per step (SPS) in meter per second, step height (SH) in centimeter, kicking speed (KS) in meter per second, and estimated maximum distance (MD) in centimeter. All variables were measured both left and right foot. The data were analyzed using descriptive analysis and the Mann-Whitney U test to find the significant difference between gender. The results showed only two independent variables were significantly different. In hopping, there was left foot height (α= 0.044) and left foot speed (α= 0.043). In conclusion, elementary school students aged 8.96 ± 1.50 years old have a similar fundamental movement skill.
