Anaerobic power, lower-body strength characteristic and some kinetics and kinematics during loaded-squat jump movement in Turkish national boxers and kickboxers

Abstract

Background & Study Aim: Among martial arts boxing and kickboxing are the most popular combat sports. The purpose of this study was knowledge about anaerobic power, lower-body strength characteristic and some kinetic and kinematics during loaded squat jump movement in Turkish national boxers and kickboxers. Material & Methods: Seven boxers (age: 25.5 +/- 2.57 years; boy: 174.2 +/- 4.38 cm; weight: 69.5 +/- 5.53 kg) and 6 kickboxers (age: 24.3 +/- 4.03 years; height: 176.1 +/- 9.45 cm; weight: 70.5 +/- 10.25 kg) who had ranks in competitions at Europe and World Championships. Totally 13 athletes (age: 25.0 +/- 3.24 years; height: 175.1 +/- 6.91 cm; weight: 70.0 +/- 7.70 kg), participated voluntarily in this study. Was applied and maximal anaerobic power, maximal anaerobic capacity, minimum anaerobic power and fatigue index values as both absolute and relative was obtained. One repetition maximal (1RM) values in full back squat (SQfull) movement was defined. Loaded-squat jump (SJLoaded) movement was applied by using an external load that corresponds to 40% of body weights of the participants by utilizing an isoinertial velocity transducer (T-Force dynamic measurement system) and values of mean propulsive velocity (MPV), peak velocity (PV), mean propulsive power (MPP) and peak power (PP) were obtained. Results: There are no statistically significant differences between velocity and power values during SJLoaded movement with 1RM and anaerobic power values of Turkish national boxers and kickboxers (p>0.05). Conclusion: As a result, the reason that there are no significant differences between both groups; it can be suggested that both groups consist of high-level athletes who participated in Europe and Word championships and their training systems and methods are similar to each other.
