Abstract

The purpose of this study was to examine the effect of variations in cone drill exercises on agility in MBC (Malang Badminton Club) badminton athletes aged 10-15 years, which was conducted by the researcher from September to November 2025. This study used an experimental design with a one-group pre-test and post-test. The sample involved in the study consisted of 10 male athletes aged 10-15 years who actively participated in training. Data were collected by measuring the subjects' agility levels before and after receiving the variation of cone drill exercises, and then the data were evaluated using the t-test method with the assistance of the SPSS software version 31. The analysis results indicated that the calculated t-value (13.648) was greater than the table t-value (1.729) with a significance level of less than 0.001. These findings indicate a significant difference in the agility of athletes before and after being given cone drill training variations. In conclusion, variations in cone drill training show an impact on improving agility in MBC (Malang Badminton Club) badminton athletes aged 10-15 years. This is proven effective with accurate and responsive footwork, allowing the shuttlecock from the opponent's direction to be returned spontaneously, strengthening the athlete's ability to maintain balance during movement or sudden stops. This study contributes to the development of physical training programs, particularly in badminton, and can serve as a reference for coaches in designing programs focused on enhancing agility.

Abstract

Smoking is known to increase oxidative stress, disrupt lipid metabolism, and accelerate the formation of oxidized Low Density Lipoprotein (LDL). Conversely, regular physical exercise enhances antioxidant capacity and improves lipid regulation. The interaction between smoking habits and intense physical activity in young athletes is important, as both may influence lipid balance and LDL levels associated with atherosclerosis risk. This study aimed to determine differences in LDL levels between smoking and non-smoking athletes aged 17–20 years. This study used an analytical observational design with a cross-sectional approach. A total of 23 male athletes were divided into smoking and non-smoking groups. Blood samples were collected via venipuncture to measure LDL levels through laboratory analysis. Data normality was tested using the Shapiro–Wilk test. Since one group was not normally distributed, the Mann–Whitney test was applied with a significance level of 0.05. Smoking athletes had a higher mean LDL level (107.10 ± 29.11 mg/dL) compared to non-smoking athletes (86.02 ± 20.34 mg/dL). However, statistical analysis showed no significant difference between the groups (p > 0.05). Descriptively, there was a tendency toward higher LDL levels in smoking athletes, although all values remained within ranges potentially influenced by regular physical activity. moking habits in young athletes did not show a significant effect on LDL levels. This may be due to physiological compensatory mechanisms induced by regular physical training, which can mitigate the negative effects of smoking on lipid metabolism.

Abstract

Dehydration is a common physiological condition that occurs after physical activity, particularly aerobic exercise, due to increased core body temperature and fluid loss through sweat. Unreplaced fluid and electrolyte loss can disrupt the body's fluid balance and impair performance and recovery. Mineral water is often used as a rehydration fluid, but it does not contain the optimal amount of carbohydrates and electrolytes to support fluid absorption. Palm sap water (Borassus flabellifer L.) has the potential to be a natural rehydration alternative because it contains simple carbohydrates and electrolytes. This study aimed to analyze the effect of palm sap water on hydration status after aerobic exercise compared to mineral water. This study used a quasi-experimental design with a randomized pretest-posttest control group design. Thirty healthy male university students aged 18–20 years were divided into two groups: the palm sap water group and the mineral water group. All subjects performed aerobic exercise, consisting of running for 30 minutes at an intensity of 64–76% of HRmax. After the activity, each group was given 250 mL of fluid according to the treatment. Hydration status was measured using Bioelectrical Impedance Analysis (BIA) with Total Body Water (TBW) as the parameter before and after the intervention. Data analysis used paired sample t-tests and independent sample t-tests. The results showed an increase in TBW values ​​in both groups, but this was not statistically significant (p>0.05). Furthermore, there was no significant difference between the palm sap water and mineral water groups in the post-test (p>0.05). This indicates that both fluids are equally effective in maintaining body fluid balance during moderate-intensity aerobic activity.Insert short English abstract here.

Abstract

This study was conducted to analyze the effect of implementing plyometric training on improving jump height among volleyball extracurricular participants at SMKN 3 Malang. Plyometric training was selected based on its ability to optimize lower-limb muscle explosive power through the stretch-shortening cycle mechanism, which is a key component in volleyball techniques such as smashing, blocking, and jump serving. This study employed an experimental method using a one-group pretest–posttest design involving 14 male participants who followed a six-week training program with a frequency of three training sessions per week. Jump performance data were collected using the Vertical Jump Test with the Jump MD device during the pretest and posttest. The results indicated an increase in jump height for all participants, with improvements ranging from approximately 2 to 6 cm. Normality and homogeneity tests confirmed that the data met the criteria for parametric analysis. The paired t-test revealed a significance value of 0.001 (p < 0.05), indicating that plyometric training had a significant effect on improving jump height. Therefore, plyometric training is recommended as an effective training program to enhance explosive power and jumping ability in student-level volleyball players.

Abstract

This study aims to determine the effect of Ramadan fasting on the VO₂Max capacity of futsal athletes from Kawat Duri Club in Malang City. Using a quantitative approach and a quasi-experimental pre-test post-test design, this study involved 10 athletes aged 16–18 years selected through purposive sampling. Data were collected using the bleep test conducted before and after the month of Ramadan. Data analysis was carried out using normality tests, homogeneity tests, and paired t-tests with SPSS software. The results showed that 7 out of 10 athletes experienced an increase in VO₂Max values after fasting, while 3 athletes showed unchanged results. The t-test results produced a significance value of < 0.001, indicating that there is a significant difference between VO₂Max values before and after fasting. These findings indicate that Ramadan fasting can have a positive impact on improving athletes' aerobic capacity, as long as it is balanced with consistent physical training and proper nutrition management. Therefore, fasting does not become an obstacle in maintaining or even enhancing the physical fitness performance of futsal athletes, particularly in terms of VO₂Max, but rather can serve as a stimulus for beneficial physiological adaptations.

Abstract

Kebugaran fisik dan performa atlet menjadi fokus utama bagi tim liga profesional, terutama menjelang kompetisi yang akan datang. Kebugaran fisik mencakup berbagai aspek seperti kekuatan, daya tahan, kelincahan, kecepatan, dan fleksibilitas, sehingga penting untuk melakukan tes pengukuran olahraga yang akurat dan sistematis. Tes ini tidak hanya membantu pelatih dalam mengevaluasi kondisi atlet, tetapi juga dalam merancang program latihan yang sesuai untuk meningkatkan performa dan mencegah cedera. Kemajuan teknologi dalam pengukuran kebugaran fisik, seperti perangkat berbasis sensor dan analisis data, memberikan metode yang lebih canggih, meskipun penerapannya memerlukan pemahaman tentang validitas dan reliabilitas alat yang digunakan. Hasil evaluasi fisik awal di Akademi Blayu FC menunjukkan variasi performa di antara pemain dalam aspek daya tahan, kelincahan, dan kekuatan eksplosif. Pemain dengan hasil baik dalam tes bleep, Illinois agility run, dan vertical jump menunjukkan potensi untuk berkontribusi lebih besar dalam tim. Namun, beberapa pemain menunjukkan hasil di bawah rata-rata, yang menandakan perlunya program pelatihan terintegrasi. Diskusi ini merekomendasikan latihan spesifik untuk meningkatkan kebugaran fisik, serta menekankan pentingnya faktor non-fisik seperti nutrisi dan manajemen stres. Kesimpulannya, pendekatan individual dalam program pelatihan dapat membantu meningkatkan performa atlet secara keseluruhan, menciptakan tim yang lebih kompetitif dan berkualitas.
