Success depends on skill, but it also depends on the physics of the problem. The task was to throw a tennis ball in a waste paper bin about 2 m away. All rights reserved.Ī simple throwing task is described to illustrate various aspects of projectile motion. The anterior-inclined seat yielded superior postural stability for throwing Boccia balls among children with bilateral spastic CP, whereas the posterior-inclined seat caused difficulty. Posterior inclination yielded less reaching distance and PVGRF, and greater COP movement range compared with the other inclines. Post hoc comparisons showed that anterior inclination allowed greater amplitude of elbow movement and PVGRF, and less COP movement range compared with the other inclines. The results of the pediatric reach test (p = 0.026), the amplitude of elbow movement (p = 0.036), peak vertical ground reaction force (PVGRF) (p < 0.001), and movement range of the center of pressure (COP) (p < 0.020) were significantly affected by seat inclination during throwing. An electromagnetic motion analysis system was synchronized with a force plate to assess throwing motion and postural stability. All participants underwent pediatric reach tests and ball throwing performance analyses while seated on 15° anterior- or posterior-inclined, and horizontal surfaces. Twelve children with bilateral spastic CP (3 with gross motor function classification system Level I, 5 with Level II, and 4 with Level III) participated in this study. The aim of the study was to examine how seat surface inclination affects Boccia ball throwing movement and postural stability among children with cerebral palsy (CP). Tsai, Yung-Shen Yu, Yi-Chen Huang, Po-Chang Cheng, Hsin-Yi Kathy Seat surface inclination may affect postural stability during Boccia ball throwing in children with cerebral palsy. We recommend that athletes perform warm-up exercises together with SS before activity to avoid detrimental effects on muscle strength. In conclusion, warm-up exercises performed together with SS abolished the impairment in medicine ball throwing distance. The throwing speed was the same over the 3 conditions. Results showed a significant group Ã- time interaction in throwing velocity (p 0.05, ES = 0.31). Both groups, TG and CG, also conducted a supervised shoulder injury prevention program with elastic tubes, as part of the warm-up, finishing with regular handball throws. TG performed a supervised MBT program, 3 times a week for a total of 6 weeks, focusing on handball-specific movement patterns. Twenty-eight players (mean ± SD age: 20.8 ± 3.3 years, height: 170.5 ± 5.6 cm, body mass: 65.2 ± 8.0 kg) were randomly assigned to an MBT group (TG n = 15) and a control group (CG n = 13). The aim of this study was to investigate the effects of 6 weeks of medicine ball training (MBT) on throwing velocity, throwing precision, and isokinetic strength of shoulder rotators in competitive female handball players.
