Bayrakdaroglu, Serdar; Can, Ibrahim
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.

Can, İbrahim
The purpose of this study was to investigate the relationship between sprint and jump performance with velocity parameters in the loaded-squat jump exercise (SQ Loaded ). In accordance with this purpose, a total of 13 athletes competing in martial sports have participated in this study voluntarily. In this study, sprint tests, vertical jump (VJ), standing long jump (SLJ) tests and one repetition maximal strength test were applied. In order to determine velocity and power parameters, SQ Loaded exercise was applied by using an external load that corresponds to 40% of body weights of the subjects via 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. Descriptive statistics, Spearman correlation analysis and Shapiro-Wilk normality tests were used for data assessment. It has been concluded that there is no statistically significant relation between 10, 20 and 30 meter sprint times and the values of MPV (r=-,332; r=-,375; r=-,446; p>.05 respectively), PV (r=-,058; r=-,118; r=-,165; p>.05 respectively), MPP (r=-,285; r=-,482; r=-,485; p>.05 respectively) and PP (r=-,205; r=-,512; r=-,391; p>.05 respectively) during SQ Loaded exercise. In addition, while no statistically significant relation has been obtained between the VJ and SLJ values of the participants and MPV (r=,496; r =,429; p>.05 respectively) and PV (r=,300; r=,223; p>.05 respectively) values during propulsive stage of SQ Loaded exercise, it has been ascertained that there is a statistically positive and significant relation between the values of MPP(r=,620; r=,580; p>.05 respectively) and PP (r=,678; r=,572; p<.05 respectively). In conclusion, it can be suggested that lifting velocity and power values don’t have a positive effect on short sprint performance; however power values affect the vertical jump and standing long jump performances positively.
