Abstract

The increasing elderly population has led to a rise in health-related problems, particularly the decline in physical function caused by aging processes such as sarcopenia, which contributes to a higher risk of falls. Elderly women are more vulnerable to reduced muscle strength; therefore, effective and safe interventions are needed. This study aimed to analyze the effectiveness of resistance band training on lower extremity muscle strength and its implications for reducing fall risk in elderly women. The study employed a quantitative approach with a quasi-experimental pretest–posttest control group design. The sample consisted of 20 elderly women (aged 60–74 years), divided into an experimental group (n=10) and a control group (n=10). The intervention consisted of resistance band training conducted for 6 weeks, with a frequency of three sessions per week. The instruments used were the 30-Second Chair Stand Test to measure muscle strength and the Timed Up and Go Test (TUG) to assess fall risk. Data were analyzed using paired sample t-tests and independent sample t-tests with a significance level of 0.05. The results showed a significant increase in muscle strength in the experimental group (p<0.05) compared to the control group. In addition, there was a significant reduction in TUG time in the experimental group, indicating a lower risk of falls. The findings suggest that resistance band training is effective in improving neuromuscular adaptation, muscle strength, and functional ability in the elderly. In conclusion, resistance band training has proven effective in increasing lower extremity muscle strength and reducing fall risk in elderly women. Therefore, it can be recommended as a safe, practical, and applicable exercise intervention.

Abstract

Knee joint stability is a crucial determinant of performance and injury prevention in professional futsal athletes who frequently perform explosive maneuvers. Muscle strength imbalance between the quadriceps and hamstrings has been identified as one of the major risk factors for functional instability. This study aimed to analyze the correlation between the quadriceps-hamstring muscle strength ratio (Q:H Ratio) and dynamic knee joint stability in professional female futsal athletes.The study employed a cross-sectional design involving 24 professional female futsal athletes. Muscle strength was measured using an isokinetic dynamometer to obtain peak torque values at an angular velocity of 60°/second, while dynamic stability was assessed using the Y-Balance Test (YBT). Descriptive statistical analysis showed that the mean Q:H ratio of the participants was 0.57 ± 0.05, which was below the ideal threshold (0.60). Pearson correlation analysis revealed a significant positive relationship with moderate strength between the Q:H ratio and the composite dynamic stability score (r = 0.612; p = 0.002). These findings indicate that the more balanced the strength between agonist and antagonist muscles, the better the resulting knee joint stability. In conclusion, the Q:H ratio is an important predictor of functional knee stability in futsal athletes. It is recommended that strength and conditioning coaches integrate eccentric hamstring strengthening programs to achieve an optimal strength ratio and reduce the risk of non-contact injuries.

Abstract

Female athletes’ participation in competitive sports requires a comprehensive understanding of specific physiological factors, including hormonal fluctuations during the menstrual cycle that may affect physical performance and injury risk. This study aimed to analyze the effects of menstrual cycle phases on cardiovascular endurance, explosive strength, and neuromuscular stability in female athletes. The study employed a quantitative approach with a quasi-experimental design using a repeated measures design on the same subjects across three menstrual cycle phases: menstruation, ovulation, and luteal phases. Samples were selected purposively based on specific criteria. Measurements were conducted using the Multi-Stage Fitness Test for VO₂max, the Vertical Jump Test for explosive strength, as well as the Y-Balance Test and knee valgus analysis for neuromuscular stability. Data were analyzed using Repeated Measures ANOVA and Bonferroni post hoc tests. The results showed significant differences (p < 0.05) in all variables across cycle phases. The ovulation phase demonstrated the highest performance in VO₂max and explosive strength, which was associated with increased estrogen levels. However, this phase also showed decreased neuromuscular stability and increased knee valgus angle, indicating a higher risk of injury. In contrast, the menstruation phase showed the lowest performance, while the luteal phase experienced declines in both performance and stability. The discussion confirmed a trade-off between improved performance and increased injury risk during ovulation due to hormonal influences on the neuromuscular system and connective tissues. Therefore, the conclusion of this study emphasizes the importance of implementing menstrual cycle-based training periodization to optimize performance while minimizing injury risk in female athletes.

Abstract

Menopause is a physiological phase characterized by a decline in estrogen levels, which affects women's quality of life and hormonal balance. This condition often triggers physical and psychological disturbances, along with an increased risk of degenerative diseases. One potential non-pharmacological intervention is resistance training, which has been shown to improve muscular strength and modulate hormonal responses. This study aimed to analyze the effect of resistance training on quality of life and hormonal balance in menopausal women. The research method used a quasi-experimental design with a pre-test and post-test control group approach. The sample consisted of 20 menopausal women divided into experimental and control groups. The experimental group participated in a resistance training program for 12 weeks with a frequency of three sessions per week. The instruments used included the Menopause-Specific Quality of Life (MENQOL) questionnaire and laboratory analysis of estradiol (E2) and Follicle Stimulating Hormone (FSH) levels. Data were analyzed using paired sample t-tests and independent sample t-tests with a significance level of 0.05. The results showed a significant improvement in quality of life and estradiol levels, as well as a reduction in FSH levels in the experimental group (p < 0.05), while the control group showed no significant changes. These findings indicate that resistance training is effective in improving physical and psychological well-being while stabilizing hormonal balance. Overall, it can be concluded that resistance training is an effective intervention that can be recommended to improve quality of life and hormonal balance in menopausal women.

Abstract

This study was motivated by the suboptimal lower limb muscle power of karate athletes in Karawang, which was assumed to result from the use of conventional and less varied training methods. Lower limb muscle power is a highly important component of physical fitness in supporting technical performance, particularly explosive movements such as kicks in kumite. An effective training method is therefore needed, one of which is plyometric training, widely recognized for improving explosive muscle performance. This study employed a quantitative approach with an experimental method using a one-group pretest-posttest design. The sample consisted of 20 karate athletes. The instrument used was the vertical jump test to measure lower limb muscle power. Data were analyzed using a paired sample t-test after fulfilling the prerequisite tests of normality and homogeneity. The results showed a significant improvement in lower limb muscle power, indicated by an increase in the mean score from 45.30 cm to 52.75 cm, representing a 16.45% improvement. Hypothesis testing showed a significance value of p < 0.05, indicating a significant effect of plyometric training on lower limb muscle power enhancement. The discussion revealed that this improvement occurred due to neuromuscular adaptation through the stretch-shortening cycle mechanism, which increases muscle contraction efficiency and explosive force. It can be concluded that plyometric training methods are effective in improving lower limb muscle power of karate athletes in Karawang and are recommended as part of training programs.
