Biomechanical analysis of the muscular power of martial arts athletes

Abstract

This study analyzes the performance of knee extension and flexion of Taekwondo and Kickboxing athletes. The power values were extracted through electromyography obtained by an isokinetic dynamometer at 60 degrees per second. These values are resulted from the square of the electromyography signal. The analysis of kick power was made using a modified wavelet algorithm considering values with 95% significance. Both groups presented equivalent power and torque capacity with different training times and experience, on the other hand, the wavelet analysis showed better results in muscular recruitment performance in athletes with more experience, in other words, power is not only performance but also power plus recruitment produces better results. This study uniquely showed that muscular enhancement capacity is not only related to the power capacity of contraction but also to motor coordination.

Differences in Force-Velocity Characteristics of Upper and Lower Limbs of Male Kickboxers

“…It is practiced either for self-defence, general fitness or as a full-contact sport. Performance in kickboxing depends on athletes' physiological [1,2], biomechanical [3] and psychological characteristics [4]. The bioenergetic profile of this sport depends on both the aerobic and anaerobic transfer energy systems.…”

Applying learning algorithms to extract anxiety levels using the heart rate variability measure

“…[14,26] In Table 2, as an example, we present the magnitude of some measures generated by the learning algorithm. The delta value did not change significantly but their values as well others measures, were verified before being discarded.…”

The Development of a Low Cost Motion Analysis System: Cekak Visual 3d V1.0

“…Existing motion capture system requires multiple expensive high performance cameras structured and calibrated within a controlled environment system (dedicated room, tracking suit and lighting capacity) [6], [9], [11], [12]. Due to that, this technology must undergo complicated set up for the advanced hardware that makes the process complex resulting difficulties for the system to be used in quasi-training environment such as sport field and training studio [13].…”
