Abstract

The proficiency in the sport of shot put is contingent upon the harmonious integration of strength, power, and technique. Notwithstanding its significance, athletes at Pembina Prestasi club in North Padang Lawas have demonstrated suboptimal outcomes, necessitating a targeted intervention to enhance their performance. The objective of study was to investigate the impact of lateral bound and tricep dip exercises on the performance of male athletes at Pembina Prestasi Club in the discipline of shot put. A pre-test and post-test experimental study was conducted on six male shot put athletes. The intervention comprised lateral bound and triceps dip exercises, conducted thrice weekly for 18 sessions over a six-week period. The efficacy of intervention was evaluated by measuring the participants' shot put performance before and after the intervention. The data were analyzed using descriptive statistics, normality tests, and paired sample t-tests. The results demonstrated a statistically significant enhancement in shot put performance subsequent to the intervention. The mean throwing distance increased from 6.40 meters to 7.74 meters, accompanied by a reduction in performance variability. The frequency distribution of performance categories exhibited a positive shift, with 66.33% of participants transitioning to the "Good" category following the intervention. A statistically significant difference was observed between the pre-test and post-test scores (p = 0.025). The implementation of lateral bound and tricep dip exercises effectively enhanced shot put performance among the studied athletes. The intervention not only improved throwing distances but also led to more consistent performances. Further research should explore these exercises with larger sample sizes and over extended periods. The integration of advanced technologies for more precise measurements and investigation of personalized training approaches based on individual athlete characteristics are recommended. Additionally, studies examining the long-term effects of these interventions and their applicability across different athlete demographics could further contribute to optimizing shot put.

Abstract

The purpose of this research is to know the relationship between legs muscles™ power, speed, and flexibility with mawashi geri chudan kicking toward boys Dojo Victori™s Karate athletes aged 12-14 years in 2022. The research method used is quantitative research through an experimental approach. Sampling technique in this research is purposive sampling with some requirements for population of boys™ Dojo Victori. This research is held starting from October 26th to November 16th, 2022. Statistical results show that legs muscle power is significantly related to the mawashi geri chudan kicking of 40.96%; leg muscle speed is significantly related to the mawashi gery chudan kicking of 56.25%; and leg muscle flexibility is significantly related to the mawashi gery chudan kicking of 72.25%. Subsequent statistical tests on all components have a simultaneously and significantly relationship to the kicking technique of 75.69%. Thus, the research will provide insight and knowledge for karate coaches to pay attention to the physical fitness components of their athletes, such as power, speed, and flexibility in the leg muscles. In addition, it is needed for further research on other components of physical fitness so that coaches get a complete and comprehensive understanding for the development of their athlete's abilities.

Abstract

The objective of this study was to assess the impact of ladder drill and dryland circuit exercises on the pace of 50-meter freestyle swimming in male swimmers aged 13-14 years at the Aquatic Swimming Club in Medan. The researchers employed an experimental approach utilising a pre-experimental design consisting of a single group with pretest and posttest measurements. The sample comprised 8 adolescent male swimmers, aged 13-14 years, who were actively involved in the club. They were recruited via purposive sampling. The study was carried out for a duration of 6 weeks, consisting of 18 training sessions, conducted 3 times a week. Measurements were obtained using 40-meter sprint tests, medicine ball throw tests, and 50-meter freestyle swimming speed tests conducted both before and after the training treatments. The data underwent analysis through normality tests, homogeneity tests, correlation tests, and regression tests. The findings demonstrated that ladder drill training made a noteworthy contribution of 59.29% to enhancing 50-meter freestyle swimming speed. Similarly, dryland circuit training had a substantial impact, accounting for 77.44% of the improvement. Furthermore, when both training methods were combined, they together contributed 62% to the enhancement of swimming speed. The study found that both ladder drill and dryland circuit training have a substantial impact on improving the 50-meter freestyle swimming speed of male swimmers aged 13-14 at the Aquatic Swimming Club in Medan. Additionally, the dryland circuit training was found to have a greater effect than the ladder drill.

Abstract

The purpose of the study was to determine the effect of various shooting exercises on shooting ability in players aged 14-17 years Victory Dairi football club in 2022. The research method was conducted through an experimental approach with a one-group pre and post-test design. The research instrument used was a shooting test developed by Ardi Nusri through a distance of 11 metres between the position of the ball and the wall as a target. The boxes on the wall that will be targeted are five boxes that have different widths and the same height. Then, what needs to be recorded during the test is the score obtained based on the target box hit by the ball and the time recorded. Scores and time records will be converted into values, accumulated, and categorised. The sample in this study is 12 people who were selected through purposive sampling technique. Data were analysed using normality test and paired t-test at 5% significance level. The results of hypothesis testing through paired t-test obtained the t-count of 12.89. Furthermore, the value was compared with the t-table value with degree of freedom of 11 at the α 0.05 significance level which is 2.201. Thus, the t-count is greater than the t- table (12.89> 2.201). These results concluded that there is a significant effect of shooting training variations on the results of football shooting ability in players aged 14-17 years Victory Dairi football club in 2022. For future research, it would be beneficial to consider a larger sample size and include a control group in order to further validate the effectiveness of shooting training variations on shooting ability.

Abstract

The objective of this study was to examine the impact of straight-line trajectory ball training on the dribbling abilities of players at the Disporasu Football School, aged between 14 and 17 years old, in Medan City, Indonesia. The research addressed the observed deficiencies in dribbling abilities, including players' difficulty in maintaining close ball control and the monotony of existing training methods. The study employed an experimental one-group pre-test post-test design and involved 17 athletes, representing the entire population of the age group at the school. The intervention comprised seven variations of straight-line trajectory ball training, conducted thrice weekly for a period of six weeks between September 21st and December 12th, 2022. The dribbling ability of the subjects was evaluated using a standardized dribbling test before and after the training period. The data were analyzed using paired sample t-tests, with normality and homogeneity checks performed prior to hypothesis testing. The results demonstrated a notable enhancement in dribbling proficiency following the intervention, with the mean dribbling time reducing from 21.18 to 19.66 seconds. The study's findings indicate that straight-line trajectory ball training significantly enhances dribbling ability in youth soccer players. These results provide coaches and trainers with an evidence-based approach to improve essential soccer skills during a crucial developmental period. The research contributes to a broader understanding of skill acquisition in soccer, offering practical insights for optimizing player performance and engagement. Additionally, the study underscores the significance of structured, progressive training programs in youth soccer development and provides a valuable template for ongoing assessment and refinement of training methods.
