This study analyzes the nutritional status and physical condition of football athletes preparing for the East Lombok Provincial Sports Week (Porprov). The research responds to the need for objective baseline evidence that coaches can use to design individualized training priorities before competition. A quantitative descriptive design was applied using secondary field-test data from 20 male football athletes. Nutritional status was examined through body mass index, whereas physical condition was evaluated using estimated VO2max from the bleep test, 30 m sprint speed, 505 agility, and standing broad jump. Data were analyzed using descriptive statistics, category distribution, coefficient of variation, composite T-score, ranking, and exploratory Pearson correlation. The athletes showed a mean body mass index of 21.86 +/- 2.03 kg/m²; 80.00% were classified as normal, 15.00% as overweight, and 5.00% as underweight. Mean VO2max was 43.76 +/- 5.25 ml/kg/min, 30 m sprint time was 3.92 +/- 0.16 s, 505 agility time was 15.99 +/- 0.52 s, and standing broad jump was 250.80 +/- 14.21 cm. The composite score indicated that 15.00% of athletes were in the very good category, 30.00% good, and 55.00% fair. Body mass index had a weak, negative, and nonsignificant correlation with total physical condition. These findings show that the team has adequate nutritional status and promising speed-power qualities, but aerobic endurance and several individual profiles require more specific training and nutrition monitoring

Athletes face high physical activity demands, placing them at risk of fatigue due to excessive training loads and inadequate recovery. Fatigue is not solely linked to physiological responses but can also be influenced by psychological factors such as stress. Heart Rate Recovery (HRR) is a simple, non-invasive parameter reflecting the heart's ability to recover after exercise, while the Perceived Stress Scale (PSS) is used to assess perceived stress levels. This study aimed to describe HRR and stress levels and to analyze the relationship between HRR and PSS scores among athletes. A descriptive quantitative approach with a cross-sectional design was employed. The study was conducted between July and August 2026, involving 24 athletes aged 16–26 years. HRR was measured following controlled submaximal exercise with passive recovery and calculated as the difference between peak heart rate and heart rate during the recovery phase. Stress levels were assessed using the PSS. Data were analyzed descriptively, and the relationship between HRR and PSS scores was tested using Spearman correlation. The results showed that the majority of athletes fell into the normal HRR category, while six athletes were in the abnormal category. Regarding stress levels, the moderate category was the most prevalent. Correlation analysis revealed a very weak negative relationship between HRR and PSS scores (r = −0.019), which was not statistically significant (p = 0.931; n = 24). Thus, no significant relationship was found between HRR and perceived stress levels in the athletes. As HRR and PSS provide distinct physiological and psychological information, their combined use has the potential to serve as part of athlete health screening

Acute Effect Of High-Intensity Intermitten Exercise (Hiie) On Cholesterol Levels And Hypertension In Individuals With A Sedentary Lifestyle

Wed, 30 Sep 2026 00:00:00 +0000

A sedentary lifestyle is a risk factor for elevated cholesterol levels and blood pressure, which can lead to cardiovascular disease. This study aimed to determine the acute effects of High-Intensity Intermittent Exercise (HIIE) on cholesterol levels and blood pressure in individuals with a sedentary lifestyle. This experimental study employed a controlled pre-test and post-test group design. Twenty-two men with sedentary lifestyles were selected via purposive sampling based on inclusion and exclusion criteria and subsequently divided into a control group (K1) and an HIIE group (K2). The HIIE group performed treadmill running at 80–90% of their maximum capacity over three sessions. Cholesterol levels and blood pressure were measured prior to the intervention and three hours after the final exercise session. Data were analyzed using paired-sample t-tests and independent-sample t-tests, with a significance level of p<0.05. The results showed that the HIIE group experienced a significant decrease in total cholesterol (p=0.001) and Low-Density Lipoprotein (LDL) (p=0.002), as well as a significant increase in High-Density Lipoprotein (HDL) (p=0.006). Systolic blood pressure also decreased significantly following the HIIE intervention (p=0.002), whereas diastolic blood pressure showed no significant change (p=0.536). Comparisons between groups revealed significant differences in lipid profiles and systolic blood pressure (p<0.05). In conclusion, HIIE has an acute effect on improving lipid profiles and lowering systolic blood pressure in individuals with a sedentary lifestyle

Archery is an accuracy sport that demands a high level of precision, physical stability, motor coordination, and consistent cognitive concentration. As the frequency and intensity of training among student athletes increase, fluid intake becomes a critical factor in preventing dehydration, which can impair athletes’ physiological performance and accuracy. This study aims to analyze student archers’ perceptions of body fluid needs as a means of preventing dehydration. A descriptive quantitative research method was used. The study sample consisted of 20 student archers at the Focus Archery Center club. The research instrument was a questionnaire using a Likert scale. The results showed a response rate of 85.95%. The distribution of perceptions showed that 80% of the athletes had very good cognitive awareness, while 20% fell into the “good” category. It can be concluded that student archery athletes at the Focus Archery Center have a very good perception of the importance of meeting their body’s fluid needs. The implications of this study emphasize the importance of coaches reinforcing this positive perception with proper hydration practices on the field

Agility is a key physical component in badminton because players must accelerate, decelerate, change direction, maintain balance, and return to a ready position within a very short time. This study aimed to analyze the relationship between body mass index (BMI) and agility among students participating in a badminton extracurricular program at SMAN 1 Kediri. A quantitative correlational design was used with total sampling involving 30 active participants. BMI was obtained from direct measurements of body weight and height and recalculated using the formula body weight in kilograms divided by height in meters squared. Agility was measured using the Illinois Agility Run Test and recorded in seconds. Data were analyzed using IBM SPSS Statistics through descriptive statistics, Shapiro–Wilk normality testing, scatterplot examination, and Spearman correlation because agility time was not normally distributed. The participants had a mean BMI of 21.75 ± 3.13 kg/m² and a mean agility time of 18.74 ± 2.58 seconds. The BMI data were normally distributed (p = 0.147), whereas agility time was not normally distributed (p < 0.001). Spearman correlation showed a significant positive relationship between BMI and agility time (rho = 0.667; p < 0.001). Because agility performance was evaluated based on completion time, this positive correlation indicates that higher BMI tended to be associated with longer test completion time and lower agility performance. These findings suggest that BMI monitoring can be used as an initial component of physical condition evaluation in school-based badminton training, although agility should also be interpreted alongside speed, lower-limb strength, balance, coordination, and training experience

This study aimed to determine the effect of depth jump training, hurdle jump training, and a combination of depth jump and hurdle jump training on the smash performance of volleyball extracurricular participants at SMP Negeri 14 Lubuklinggau. This study employed an experimental method using a pretest–posttest design. The research participants consisted of 45 volleyball extracurricular participants who were divided into three groups: the depth jump group, the hurdle jump group, and the combination group. Data were collected through smash performance tests conducted before and after the training intervention. The data were analyzed using the Wilcoxon Signed Ranks Test to determine the effect of each training method and the Kruskal–Wallis test to compare the improvement in smash performance among the three groups. The results of the Wilcoxon Signed Ranks Test showed that depth jump training had a significant effect on smash performance, with a Z-value of -3.417 and an Asymp. Sig. (2-tailed) value of 0.001 (p < 0.05). Hurdle Jump training also had a significant effect, with a Z-value of -3.425 and an Asymp. Sig. (2-tailed) value of 0.001 (p < 0.05). Furthermore, the combination of depth jump and hurdle jump training significantly improved smash performance, with a Z-value of -3.308 and an Asymp. Sig. (2-tailed) value of 0.001 (p < 0.05). The Kruskal–Wallis test showed no statistically significant difference in the improvement of smash performance among the three groups, with a Chi-Square value of 3.340, df = 2, and an Asymp. Sig. value of 0.188 (p > 0.05). Although the Depth Jump group had the highest Mean Rank (26.83), followed by the Hurdle Jump group (23.87) and the combination group (18.30), the difference was not statistically significant. Therefore, Depth Jump training, hurdle jump training, and the combination of both can be used as alternative training methods to improve the smash performance of volleyball extracurricular participants, although none of the three methods can be stated to be significantly more effective than the others

Students of Sports Coaching Education (PKO) and Sports and Health Education (PORKES) have dual demands in undergoing academic and sports activities. They must attend lectures as well as undergo exercises and practical activities that require good physical condition and concentration. These conditions can cause fatigue, burnout, and increase the risk of repetitive injuries. This study aims to understand the experiences of PKO and PORKES students in dealing with burnout and repetitive injuries while undergoing academic and sports activities. The research uses a qualitative approach with the narrative inquiry method. Data were obtained through in-depth interviews with 3–5 students who were selected purposively based on their experiences of experiencing repetitive injuries and symptoms of academic-athletic burnout. The data were analyzed thematically to identify students' experiences, impacts, and strategies in dealing with these conditions. The results of the study show that academic load and unbalanced training can cause emotional fatigue, decreased concentration, decreased performance, and the appearance of burnout. These conditions are also related to repeated injury experiences and cause psychological impacts and obstacles in completing academic activities. To deal with this, students use various strategies, such as organizing and modifying exercises, rehabilitating, communicating with lecturers, and utilizing peer support. This research shows that managing academic and sports load and appropriate support are needed to help students maintain health, complete education, and carry out sports activities in a more balanced manner

This study aimed to examine the changes in cardiovascular endurance following a High-Intensity Interval Training (HIIT) program among U-12 futsal athletes of Ora Et Labora in 2025. This study employed a pre-experimental method using a one-group pretest–posttest design. The participants were 14 U-12 futsal athletes who met the inclusion criteria, namely actively participating in the training program, being registered as Ora Et Labora U-12 futsal athletes, and completing the pretest and posttest. Cardiovascular endurance was measured using the Multistage Fitness Test (Beep Test), with VO₂max expressed in ml/kg/min. The HIIT intervention was conducted over 16 training sessions at a frequency of four sessions per week, using high-intensity exercise intervals of 30 seconds followed by 15 seconds of recovery. The results showed an increase in mean VO₂max from 47.69 ml/kg/min at pretest to 50.99 ml/kg/min at posttest, representing a mean increase of 3.30 ml/kg/min. These findings indicate that VO₂max increased following the HIIT intervention among the participating U-12 futsal athletes. However, because this study did not include a control group, the observed improvement cannot be attributed solely to HIIT. Further studies using controlled experimental designs and larger samples are needed to determine the specific contribution of HIIT to improvements in cardiovascular endurance among young futsal athletes
