The aim of the research was to develop the design of a striking dummy and the theoretical foundations of martial arts strikes and to test its effectiveness in a pedagogical experiment. This paper presents the design of a striking dummy and the foundational theories behind martial arts strikes. We used modern microelectronics, including a diverse range of sensors, for executing a multitude of electromechanical measurements. Furthermore, we developed a software package for collecting, analysing and storing data from sports training. Methods: The TaePunchBag program, part of this setup, integrates several combat sports including boxing, taekwondo, kickboxing, karate and hand-to-hand combat. It classifies and evaluates various types of hand and foot strikes, conducting specialized tests to measure attributes such as speed, response to signals, force up to 800 kg and impact accuracy. Results: The article details the tasks and operation of the “Software complex for measuring sportsmen’s blows”. Additionally, the advanced range of microelectronic sensors supports various electromechanical measurements, further complemented by a software package that handles data collection, analysis and storage from sports training. Conclusions: The application of this sophisticated software system to martial arts strike measurements, particularly in conjunction with a novel punching bag apparatus, may significantly improve our understanding of impact kinetics. This integrated approach is expected to produce accurate and reliable data on punch and kick power, enabling coaches and athletes to refine training strategies and boost their output.

The objective of this research was to develop a sensor device to control and evaluate the jumping ability of elite volleyball athletes and to test its efficacy in a pedagogical experiment. Methods: The study involved determining the pulsometric and respiratory parameters during test loads, indicative of the endurance and speed–strength aspects essential for volleyball performance. Additionally, the necessity for post-training and post-competition jump performance restoration via short-term relaxation exercises was identified. Results: Through the developed computer program, a method for storing maximal vertical jumps in computer memory was established. Furthermore, a technique was developed to determine the functional significance of maximum vertical jump performance among elite volleyball players. Notably, participants in the experimental group, who performed specialized exercises developed within the experimental framework, exhibited discernible progressive improvements compared to the control group participants. Before the experiment, the maximum number of jumps in the experimental group was 29.2 ± 2.73, with a jump time of 31.7 ± 3.08. Conclusions: The equipment developed for monitoring and assessing volleyball players’ jumping ability has proven effective, warranting its incorporation into training regimens.
