The main aim of the study was to design a new system to measure punching forces in boxers. In addition, the study examined whether there were any relationship between force of punches and power of jump. A total of 9 boxers (age: 17.5±1.2 years, body height: 174.1±8.1 cm, body mass: 73.9±11.8 kg) participated in the study. The punching bag was equipped with acceleration transducers and gyroscopes embedded in a cylinder covered with a layer to absorb shock as well as a set of colour signal diodes. Value of the punching bag’s acceleration was used for calculating: strike force; the punching location on the bag; and time of a strike. The relative error of force calculation was 3%; the relative error in acceleration measurement was less than 1%. The maximal straight of rear and lead punching forces were 1702.4±497.8 N and 1262.0±417.7 N in boxers, respectively. Strong correlations were found between the punching force and power of lower limbs developed for the ACMJ, CMJ and SPJ jump. Height of rise of the body mass centre and punching force correlated insignificantly. Based on these findings, it was concluded that the modified punching bag is a good diagnostic tool for combat sports. The measurement of power during the jump may be a good diagnostic test in boxers.
