“…In short, the relationship between ball kick velocity and leg strength has not been examined in detail. In the case of isokinetic muscle contraction, contraction characteristics differ for each person and with respect to angular velocity (Tsuyama, Kobayashi, Saito, Kiyota, & Nakajima, 2007). In addition, the type and amount of necessary leg strength differs among competitive sports.…”

“…This device can evaluate and increase the muscle strength of various body sites (Tsuyama, Kobayashi, Saito, Kiyota, & Nakajima, 2007;Chan, Chan, Fong, Wong, Lam, & Lo, 2011). In addition, it has the additional advantage that players and coaches can select body sites and specific motions of interest, and examine competitive characteristics in order to improve the strength of specific muscle groups.…”

This study compared soccer players with non-soccer players, with respect to the relationship between ball velocity due to an instep kick and various leg strengths. Ten young university soccer players and ten other athletes (non-soccer players) had their instep kick ball velocity (BV) measured with respect to isokinetic leg strength. The BVs from the soccer players were significantly greater than those from the non-soccer group. However, this group also had significantly inferior dorsiflexion strength of the ankle joint (low: low angular velocity), extension of the knee joint (low, middle, and the total value of the evaluation parameters of all angular velocities), and flexion of the hip joint (middle). Positive and significant correlations between BV and flexion and dorsiflexion strengths of the ankle joint (low), extension (low, middle, high, and total), and flexion of knee joint (low and total), extension (low, high, and total), and flexion (high) of the hip joint were found in the soccer group, but a significant negative correlation was found only between BV and hip joint flexion strength (middle) in the non-soccer group. In conclusion, soccer players have similar or inferior isokinetic leg strength in comparison to other athletes, but their BV is faster.

근육의 두께(muscle thickness), 단면적(cross sectional area, CSA) 및 근속 각도(pennation angle) 등의 근육의 구조적 특성과 축구 등의 종 목 특성과의 관련성을 검토한 연구에 의하면, 우수 청소년 남자 축구 선수를 대상으로 4-15 RM의 2-4세트, 주 3회의 8주간에 걸쳐서 하지 근력운동을 실시한 후에 초음파 영상(ultrasound imaging)을 통해 근 육의 두께를 분석한 결과, 내측광근(vastus medialis)의 두께가 현저하 게 높게 나타났다고 보고하였다[1]. Kubo et al. [2]은 남자 프로축구선 수와 유소년 축구선수를 대상으로 주측 하지(dominant leg) 및 비주측 하지(non-dominant leg)의 대퇴사두근(quadriceps femoris), 슬와부근 육(hamstring muscles) 및 내전근(adductor muscles)의 CSA를 자기공명 PURPOSE:The purpose of this study was to determine the effect of vastus lateralis muscle fascicle length on isokinetic muscle strength and dynamic balance in youth soccer players. METHODS: Fourteen youth soccer players were divided into long fascicle length group (LFG, n =7) and short fascicle length group (SFG, n=7) by fascicle length of vastus lateralis muscle using ultrasound imaging. And measurements of muscle thickness, fascicle pennation angle, and physiological cross-sectional area were taken at the same location. Additionally, maximal isokinetic strength of knee extensors was assessed at 60°/sec and 120°/sec and a Y-balance test was completed. RESULTS:Fascicle length and ratio of fascicle length/lower limb length were significantly greater in LFG than that in SFG (p<.001). Fascicle pennation angle (p<.01) and physiological cross-sectional area (p<.05) were significantly greater in SFG than that in LFG. The isokinetic maximal strength of knee extensors at 120°/sec was significantly greater in SFG than that in LFG (p<.05). The composite score of Y-balance was significantly greater in SFG than that in LFG (p<.05). CONCLUSIONS:Our results show differences in architectural characteristics of the vastus lateralis. Further, the maximal isokinetic strength of knee extensors at 120°/sec and the ability of dynamic balance were greater in short vastus lateralis fascicle length of youth soccer players.

[4]은 유소년 축구선수를 대상으로 주측 및 비주측 비복근 내측두(medial gastrocnemius)의 근육 두께를 분석 한 결과, 비주측과 비교해서 주측에서 유의하게 높게 나타났다고 하면 서, 주측 다리의 근속 길이(fascicle length)도 길게 나타났다고 보고하 였다. 또한 성인 축구선수와 유소년 축구선수의 대퇴근육의 CSA를 분 석한 결과, 대퇴사두근 CSA의 비율은 성인 축구선수와 비교해서 유소 년 축구선수가 높게 나타났고, 반면에 슬와부근육과 내전근 CSA의 비 율은 유소년 축구선수와 비교해서 성인 축구선수에서 보다 높게 나타 났다고 보고하였다[5,6]. 따라서 축구 훈련은 슬와부근육과 내전근의 성장을 보다 발달시키는 것으로 생각된다. 특히, 골격근의 근속 길이는 근육의 천건막(superficial aponeurosis) 과 심건막(deep aponeurosis) 사이에 근속(muscle fascicle)이 교차하는 길이로 근육의 최고단축속도(maximal shortening velocity)와 관련이 있으며[7], 유소년 축구선수의 외측광근(vastus lateralis)은 슈팅 시 장 요근과 함께 최고 구속(maximal ball velocity)을 결정...

Background: This study investigated body composition, bone health status and isokinetic muscular performance among Malaysian young male badminton players, archers and non-athletes as controls. Methods: Thirty-three participants (mean age: 15.1 [1.4 years]) were divided into three groups, which were non-athlete control (n = 11), archery (n = 11) and badminton (n = 11) groups. Participants’ percentage of body fat (%BF), muscle mass or fat-free mass (FFM) and bone speed of sound (SOS) were measured. In addition, participants’ knee (flexion and extension) and shoulder (extension and flexion) peak torque (PT, an indicator of muscular strength) and average power (AVG.P) were measured using an isokinetic dynamometer. Results: Badminton athletes showed a significant higher (P = 0.021) shoulder extension AVG.P at 180°/s compared to the non-athletes. Both badminton and archery athletes showed significantly higher values of isokinetic knee flexion AVG.P at 180°/s and 300°/s, knee extension PT and AVG.P at 180°/s when compared to non-athletes. In badminton players, significant positive correlations were observed between FFM with arm bone SOS (r = 0.727, P = 0.011) and shoulder PT at 60°/s (r= 0.736, P = 0.010), respectively. Arm bone SOS showed significant positive correlations with shoulder PT at 60°/s (r = 0.674, P = 0.023), shoulder flexion AVG.P at 300°/s (r = 0.614, P = 0.023) and shoulder extension AVG.P at 300°/s (r = 0.633, P = 0.049), respectively. Leg bone SOS was also significantly positive correlated with knee flexion AVG.P at 300°/s (r = 0.727, P = 0.011) and knee extension AVG.P at 300°/s (r = 0.639, P = 0.034), respectively, in badminton players. Conclusions: Engagement in badminton and archery sports of athletes could enhance muscular strength and power compared to non-athletes.
