A Comparative Study on the Effectiveness of Flat and Spin Serves in Direct Points Simulation Matches
No full textThis study aims to compare the effectiveness of two service techniques, namely flat serve and spin serve, on direct point acquisition in a simulated tennis match situation. The subjects of the study consisted of 20 male junior tennis players, aged 14–16 years, who were divided into two groups based on service technique. Each group was to use one type of serve consistently during three sets of simulated matches. The variables observed included the number of direct points, service speed, accuracy, rally length, and number of double faults. The results of the independent t-test analysis showed that the flat serve group scored a higher average direct points mean, 9.2; SD = 2.15, than the spin serve group mean, 6.8; SD 1.69, with a t-value = 2.74; p = 0.013. Supporting analysis also showed that the flat serve had higher speed, while the spin serve was superior in accuracy and rally duration. These findings indicate that the flat serve is more effective for a fast point scoring strategy, while the spin serve is more suitable for long rallies and game control. Therefore, coaches are advised to integrate service variation training as part of the development of athletes’ playing strategies.
Cardiorespiratory Fitness Level of College Students in terms of Abdominal Circumference, Body Mass Index, and Gender
No full textCardiorespiratory fitness refers to the integrated ability of the cardiovascular system with the respiratory system to provide oxygen to body tissues and is measured through VO₂max parameters. This variable is related to gender, abdominal circumference, and Body Mass Index (BMI). This cross-sectional study was analytical and involved 43 students as subjects selected by purposive sampling technique. Data were analysed descriptively and analytically using frequency distribution and chi-square test. The majority of the subjects were female (72%), with a mean abdominal circumference of 78.84 cm and included low risk (53%), a mean BMI of 24.88 and included normal (56%), and a mean VO2 max of 11:02 including a very poor category (72%). Correlation tests of gender, abdominal circumference, and BMI with VO2max showed p values of (p=0.000); (p=0.019) and (p=0.645) respectively, which means that there are differences in cardiorespiratory fitness between men and women; there is a statistically significant relationship between abdominal circumference and VO2max level and there is no statistically significant relationship between BMI and VO2max level. Exploration of the biological mechanisms behind gender disparities and the influence of body fat distribution on VO₂max needs to be studied longitudinally, in addition to testing the effectiveness of integrated interventions in improving the aerobic capacity of at-risk populations.

The Impact of Aerobic Dance Intensity on Blood Pressure Reduction in Physically Active Elderly Women
No full textThis study aims to determine the relationship between aerobic dance intensity and blood pressure reduction in active elderly women who routinely participate in community exercise programs. The research design used is correlational with a quantitative approach. The sample consists of members of the aerobic dance community in Taman Pakui Sayang (TPS), Makassar, comprising 20 elderly women aged 45–59 years who participate in aerobic dance at least twice a week for 8 weeks. Data were collected through blood pressure measurements before and after the intervention, as well as monitoring exercise intensity using the Borg RPE (Rating of Perceived Exertion) Scale. The results of the analysis showed a significant negative correlation between aerobic dance intensity and a decrease in systolic with r = -0.62; p = 0.001 and diastolic (r = -0.55; p = 0.004) blood pressure. These findings indicate that the higher the intensity of the exercise performed, the greater the decrease in blood pressure that occurs. Thus, moderate to high intensity aerobic dance can be an effective non-pharmacological strategy in the management of hypertension in elderly women.
