Analyzing optimal muscle dynamics during handstands: a comprehensive investigation of skilled gymnasts
Journal of Physical Education and Sport, 2024
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 3.10.0applications 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.
Comprehensive scientific examination of leg length discrepancy in junior badminton players
Journal of Physical Education and Sport, 2023
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.

The determination of this study was to investigate the selected kinematical parameters of 3 to 5 years of experienced long jumpers. Analysis of long jumpers' performance in relation to kinematic variables was the objective. A total of 15 jumpers participated in this study. To capture kinematical data by using a good-resolution camera to capture the jumper's performance (GoPro Hero7 Black Action Camera with Touch Screen 4K Ultra HD Video 60 fps). The chosen kinematical parameters were Last stride length distance (LSL), Ground Contact Time (GCT), Knee angle (at the time of take-off) and standing broad jump (SBJ), and long jump performance for capturing the movement of the jumpers, the camera was placed perpendicular at a distance of 15mts right side of the runway and take-off board, the height of the camera was set at 5ft from the ground. All jumps are performed by the selected jumpers. The recorded video was analyzed using Silicon Coach Motion Analyzer Software. After that, the acquired data were calculated by using computer-based SPSS software, and the level of significance was set at 0.05. The findings of the study indicate that the standing broad jump, knee angle and ground contact time have markable differences in the long jump performance, other than the last stride length distance.

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.

Umbilicus plays significant role to digestive system including overall health of body. It is the center point of the body it is the only way of feeding the baby in womb during the pregnancy. Location and placement of the umbilicus is very important for a healthy being. In Yogic system Manipur plexus said to be located at the Place of navel and saman Prana is also there which is completely dedicated for digestion, this prana gives energy to the digestive process it can happen only when location of umbilicus is proper. Displaced umbilicus does not give any big change in physical appearance but give the change at health level which may felt by the affected one. Umbilicus displacement can be managed by doing some particular Yoga poses, by applying byol magnet on big right toe first joint in a particular manner of application with the help of doctor tape under the super vision of magnetic acupressure therapist, by pressing ear dividing line’s center point and by pressing complete toe for six seconds at least for three times with putting heel of patient on healer’s palm with other hand healer will press the complete toe with gentle force. This complete toe pressing method can be applied only on the toe which is smaller after comparing both leg and toe, toe comparison can be done easily with lying down the affected one on a flat surface. This complete toe pressing method should be avoided for those who has any injury in leg, knee, and toe. After applying any of these above methods balanced and proper localized umbilicus can be seen with healthy digestive system. This article present what methodologies can be used for displaced umbilicus to balance or localized it.
