Badminton is a fast-paced sport that requires not only physical fitness but also strong mental skills like anticipation and quick decision-making. This study introduces a new training method called “One-Way Mirror Perceptual Training”, which uses a one-way mirror to block players' view of their opponent, forcing them to rely on their perception and reaction skills instead of visual cues. Twenty male badminton players aged 13-25 were divided into two groups: an experimental group that received the special training for six weeks and a control group that continued with regular practice. The training focused on improving agility, reaction time, coordination, and accuracy. Performance was measured before and after the training using tests like the Four Corner Run Test (FCRT) and agility drills. The experimental group showed significant improvement, with faster reaction times, better movement, and higher performance scores, while the control group had little change. These results suggest that the One-Way Mirror Perceptual Training helps players improve their mental and physical skills, making them more prepared for high-level competition. This study highlights the importance of including perceptual training in badminton and suggests that similar methods could be useful in other fast-paced sports.

The observed benefits include enhanced problem-solving abilities, improved creativity, and the practical application of theoretical knowledge, all contributing to a good educational experience. This interdisciplinary approach not only prepares students for a technologically advanced society but also ongoing research, collaboration, and implementation to maximize its educational potential in both physical education and engineering.

The present study focus on the examination of the selected muscle power by the maximal voluntary effort (MVE) for national-level participated Bodybuilders and Weightlifters (BB and WL). This study analyzed the muscle power of experienced BB and WL with one of the technically approved low-cost myoware muscle sensor. The subjects were n=10 male BB and n=10 male WL i.e. a total of N=20 subjects were selected from the Tamil Nadu region. The myoware muscle sensor (MMS) of the biceps brachii and triceps brachii muscles during the MVE was recorded. The MMS surface electrodes were placed at the motor point of each muscle during MVE the muscular activity was stored by the data logger (Arduino UNO) and the results were gathered from the data acquisition system. The collected data were analysed in a T-test by computer-based software SPSS. The data analyzed for the biceps extension (BE) showed that out of the chosen subjects, the MVE of BB (55%) was slightly better than WL (45%), the biceps flexion (BF) showed that out of the chosen subjects, the MVE of BB (52%) was slightly better than WL (48%), the triceps extension (TE) showed that out of the chosen subjects, the MVE of WL (53%) was slightly better than BB (47%), the triceps flexion (TF) showed that out of the chosen subjects, the MVE of WL (55%) was slightly better than BB (45%). The muscle power level of experienced BB and WL showed no significant changes during the MVE task (contraction), except that the MMS values were slightly higher in BB than the WL in the Biceps brachii muscle and the WL had better triceps brachii muscle power than the BB.

The objective of this research was to conduct a comprehensive analysis of Leg Length Discrepancy (LLD) among in young badminton players with the aim of mitigating back discomfort and reducing injuries in their current training environments. Numerous studies have established a connection between LLD and various musculoskeletal issues in different sports, causing asymmetrical gait and low back pain. Consequently, many players find their daily routines disrupted, leading to burnout or dropout from the sport. To assess the current situation, this study focused on 1502 young badminton players aged 9–12 from the states of Tamil Nadu and Puducherry. LLD can be challenging to diagnose and treat, especially in growing children, and various methods and equipment are available for assessment. In this research, the "Delta Leg" (DL) measuring tool was employed, measuring discrepancies from millimeters to centimeters. The 0–10 Numeric Pain Rating Scale was used to determine the level of pain. The analysis involved the application of percentage techniques (P = n × 100 / N) and Pearson correlation. The results indicated that 218 (15%) of the players had equal-length lower limbs, while 1284 (85%) exhibited LLD in varying degrees. Among the LLD players, 354 (24%) had discrepancies greater than 1 cm, 753 (50%) had discrepancies less than 1–2 cm, 171 (11%) had discrepancies less than 2–3 cm, and 6 (0.40%) had discrepancies less than 3 cm. LLD was notably prevalent among young badminton players aged 9 to 12, warranting careful attention. Even mild LLD should not be overlooked, emphasizing the importance of coaches, physiotherapists, physical education instructors, and doctors in closely monitoring players' leg mechanics. Immediate corrective actions are essential, and continuous monitoring is imperative, because LLD may necessitate intervention before reaching skeletal maturity. The use of insoles is recommended to alleviate muscular and/or joint problems and gait issues in players. Additionally, some players with equal leg lengths exhibited pronation and supination in their ankles, suggesting the need for future research to explore other lower limb issues experienced by badminton players.

This study aimed to evaluate the muscle dynamics involved in single and double-arm handstands performed by five skilled gymnasts, with a mean age of 23.6 ± 1.94 years. Myoware Muscle Sensor (AT-04-001) (MMS) signals were collected from three key upper limb muscles: Wrist Flexor (WF), Triceps Brachii (TB), and Lateral Deltoid (LD), all on the dominant side of the body. To facilitate data collection and processing, Internet of Things (IoT) programs were employed, utilizing Arduino IDE and Python 3.10.0 applications to connect the NodeMCU (ESP8266) via server and client code. The NodeMCU's display frequency range was set at 0–1024 Hz, with a Baud (Bd) rate of 9600 in Arduino, which is a crucial parameter for visualizing the data accurately. It continuously reads the serial and plotter monitor signals from the MMS through the A0 pin. The processed data was transmitted wirelessly by the NodeMCU, displayed on a monitor, and recorded for analysis. Participants executed three trials of their maximum handstand performance on the floor; the gymnasts peak level of 15 seconds performance was used for analysis (i.e., the middle time of the best trial; e.g., maximum performance was 45 seconds in this 16–30sec used). The observed muscle stimulation range was from a minimum of 109617 Hz to a maximum of 151292 Hz. Overall, one-arm handstands (52.79%) demonstrated better muscle activation than double-arm handstands (47.21%). The analysis revealed a statistically significant positive Correlation (r) and Probability (p) between the WF and LD (r = 0.870, p = 0.001). However, no significant correlations were observed between the WF and the TB (r = 0.507, p = 0.134) or the TB and the LD (r = 0.491, p = 0.150). To conclude, despite comparable inter-muscle contributions, the study suggests a significant association between WF and LD. Future research can build on these findings, exploring additional muscle groups and refining training protocols for performance optimization and injury prevention. This study encourages broader investigations, including more muscles in the upper and lower body, with advanced research laboratories and larger sample sizes.
