Kinematic analysis is crucial in sports science and biomechanics for optimizing performance and helping in rehabilitation. This study compares fifteen kinematic analysis tools, namely Siliconcoach, Kinovea, Templo by Contemplas, Gaiton, Helix 3D By Rundna, Dartfish, Coach’s Eye, Vicon, Motion Analysis Corporation, Noraxon Myoresearch, Qualisys, Pro-Trainer, Xsens, Simi Motion, And Shutter Precision. The comparison focuses on performance benchmarks, usability, accuracy, reliability, and cost-effectiveness. High-end systems like Vicon and Qualisys excel in precision and real-time data processing, ideal for research and professional use, while tools like Coach’s Eye offer accessible yet less precise analysis suitable for general coaching. Usability varies, with Kinovea and Dartfish noted for their user-friendly interfaces, while advanced systems require more extensive training. Accuracy is critical, with top systems providing high precision through sophisticated technologies. Cost varies widely, from free tools like Kinovea to premium systems like Vicon. This study provides valuable insights for selecting the most appropriate scientific tools and methods

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 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.

This study explores integrating engineering concepts into the physical education (PE) curriculum, aiming to develop student experiences and progressive development. The objectives include exploring benefits associated with incorporating engineering principles, including preventing injuries through movement analysis and biomechanics, stimulating creativity and problem-solving skills with sports equipment, and strengthening theoretical knowledge through practical experiences in designing fitness equipment. The methods involved a comprehensive approach by literature reviews. 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.
