“…Here, it can be speculated that as it involves the action of several joints, performance during the jump depends on many specific independent interrelated variables, such as motor control, intramuscular coordination, strength levels, the degree of muscle power and the execution technique, among others (WEISS et al, 1997). While for some authors the height of the jump height depends largely on the muscular strength of the quadriceps (ARAGÓN-VARGAS; GROSS, 1997), for others the ability to transfer mechanical energy from the proximal to the distal segments is much more important when determining the vertical jump performance (KOLLIAS et al, 2001).…”

“…선행 연구에 의하면, 관절 역학적 측면에서 최저점에서 추진을 시작하는 초 기 시점에서의 관절 회전력 (Bobbert, Karin, Gerritsen, Litjens & Van Soest, 1996), 이지 시점에서의 관절 파워 (Pandy & Zajac, 1991) 등이 수행력에 중요한 요인으로 제시되었다. 또한 동작전 략이나 테크닉 측면에서 이지 순간의 신체중심 높이 (Kollias, Hatzitaki, Papaiakovou & Giatsis, 2001), 두관절 근육(biarticular muscle)을 통한 파워의 효과적 전이 (Bobbert & van Ingen Schenau, 1988;Pandy & Zajac, 1991), 반동을 통한 근육의 SSC(stretch shortening cycle) 기전의 활용 (Anderson & Pandy, 1993;Bosco, Viitasalo, Komi & Luhtanen, 1982), 상지 스윙의 효 과적인 활용 (Feltner, Bishop & Perez, 2004;Hara, Shibayama, Lees, Vanrenterghem & Clercq, 2004;Takeshita & Fukashiro, 2006) 등의 요인들이 보고되었으며, 근위-원위로의 순차적인 근 육 활성 (Bobbert & van Ingen Schenau, 1988), 근위-원위 관절로 의 순차적인 신전 운동과 그 타이밍 (Pandy & Zajac, 1991) (Bobbert & van Ingen Schenau, 1988;Riewald, 2011) 궁극적으로 수행력을 결정한다는 점을 고려하면 보다 구체적이고 실질적인 정보는 분절 및 관절의 운동학 및 운동역학적 요인에서 찾을 수 있을 것이다. 결국 하지 각 분절의 역학적 요인과 이들의 상호 작용이라 할 수 있는 협응 패턴은 수행력을 결정하는 주요한 요인이 될 것이다.…”

The purpose of this study was to investigate the effects of joint kinetics and coordination on within-individual differences in maximum vertical jump. 10 male subjects aged 20 to 30 performed six trials in maximum vertical jump and with based on jump height the good(GP) and bad(BP) performances for each subject were compared on joint kinetics of lower extremity and coordination parameters such as joint reverse and relative phase. The results showed that maximum moment, power, and work done of hip joint and maximum moment of ankle joint in GP were significantly higher than that in the BP but no significant differences for the knee joint. We could observe a significant difference in joint reverse timing between both conditions. And also the relative phase on ankle-knee and ankle-hip in GP were significantly lower than that in the BP, which means that in GP joint movements were more in-phase synchronized mode. In conclusion, mechanical outputs of hip and ankle joints had an effect on within-individual differences in vertical jump and the inter-joint coordination and coordination including sequence and timing of joint motion also might be high influential factors on the performances within individual.

“…In addition, squat jumping exercise is also applied in order to evaluate an individual's strength competency performed by using different external loads (Garcia-Ramos et al, 2016; and it is generally applied by using both a free-weight barbell and smith machine Stone et al, 2003). As known in physical science, jumping height is directly related to take-off velocity and many authors assess take-off velocity in order to determine vertical jumping performance (Luhtanen & Komi, 1978;Kollias et al, 2001;Moir et al, 2008). Take-off velocity is an unchanging feature even when the individual jumps from the ground (Reiser et al, 2006) and it is closely related to maximal velocity.…”

The purpose of this study is to investigate the relationship between repeated sprint performance and velocity values during loaded-squat jump exercise. In accordance with this purpose, 23 kickboxing athletes (age: 21,1 ± 2,10 years; height: 178,7±5,01 cm; weight: 70,8±7,85 kg) participated voluntarily in this study. Participants were performed to repeated sprint test and loaded-squat jump exercise by using an external load corresponding to 40 % of their body weight and velocity parameters were obtained as mean velocity (MV), mean propulsive velocity (MPV) and peak velocity (PV). Descriptive statistics were used in analysis of data. In addition, Spearman Correlation Analysis was used to determine the relationship between repeated sprint performance and velocity values during loaded-squat jump exercise. According to the analysis results; while total running times and fatigue index values in repeated sprint test of subjects were obtained as 52.4 (±1.96 sec) and 4.98 (±2.36%) respectively; velocity values during loaded-squat jump exercise were obtained as 1.38 (±,07 m/s -1 ) for MP, 1.54 (±,10 m/s -1 ) for MPV, and 2.58 (±,15 m/s -1 ) for PV. In addition, it was determined that there was no any statistically significant difference between MP (r= -,148; r= -,072, p>0.05, respectively), 335;150, p>0.05, respectively), PV (r= ,010; r= -,034, p>0.05 respectively) and total running time and fatigue index values in repeated sprint test. As a result, it can be suggested that velocity values during loaded squat jump exercise have no statistically significant effect on repeated sprint performance.
