ABSTRACTThis study identified key somatic and demographic characteristics that benefit all swimmers and, at the same time, identified further characteristics that benefit only specific swimming strokes. Three hundred sixty-three competitive-level swimmers (male [n = 202]; female [n = 161]) participated in the study. We adopted a multiplicative, allometric regression model to identify the key characteristics associated with 100 m swimming speeds (controlling for age). The model was refined using backward elimination. Characteristics that benefited some but not all strokes were identified by introducing stroke-by-predictor variable interactions. The regression analysis revealed 7 “common” characteristics that benefited all swimmers suggesting that all swimmers benefit from having less body fat, broad shoulders and hips, a greater arm span (but shorter lower arms) and greater forearm girths with smaller relaxed arm girths. The 4 stroke-specific characteristics reveal that backstroke swimmers benefit from longer backs, a finding that can be likened to boats with longer hulls also travel faster through the water. Other stroke-by-predictor variable interactions (taken together) identified that butterfly swimmers are characterized by greater muscularity in the lower legs. These results highlight the importance of considering somatic and demographic characteristics of young swimmers for talent identification purposes (i.e., to ensure that swimmers realize their most appropriate strokes). 相似文献

Previous research has highlighted the positive effect that different warm-up protocols have on golf performance (e.g. Sorbie et al., 2016; Tilley & Macfarlane, 2012) with the design of warm-ups and programmes targeting and improving golf performance through the activation and development of specific muscle groups. This study aimed to examine the acute effects of two warm-up protocols on golf drive performance in comparison to a control condition. Using a randomised counterbalanced design over three testing sessions, twenty-three highly skilled golfers completed the control, dynamic and resistance-band warm-up conditions. Following each condition, a GC2 launch monitor was used to record ball velocity and other launch parameters of ten shots hit with the participants’ own driver. A repeated-measures ANOVA found significant increases in ball velocity (ηp2 = .217) between the control and both the dynamic and resistance-band warm-up conditions but no difference between these latter two, and a reduction in launch angle between control and dynamic conditions. The use of either a dynamic stretching or resistance-band warm-up can have acute benefits on ball velocity but golfers should liaise with a PGA Professional golf coach to effectively integrate this into their golf driving performance. 相似文献

The purpose of this study was to estimate the optimal body size, limb-segment length, girth or breadth ratios for 100-m backstroke mean speed performance in young swimmers. Sixty-three young swimmers (boys [n = 30; age: 13.98 ± 0.58 years]; girls [n = 33; age: 13.02 ± 1.20 years]) participated in this study. To identify the optimal body size and body composition components associated with 100-m backstroke speed performance, we adopted a multiplicative allometric log-linear regression model, which was refined using backward elimination. The multiplicative allometric model exploring the association between 100-m backstroke mean speed performance and the different somatic measurements estimated that biological age, sitting height, leg length for the lower-limbs, and two girths (forearm and arm relaxed girth) are the key predictors. Stature and body mass did not contribute to the model, suggesting that the advantage of longer levers was limb-specific rather than a general whole-body advantage. In fact, it is only by adopting multiplicative allometric models that the abovementioned ratios could have been derived. These findings highlighted the importance of considering somatic characteristics of young backstroke swimmers and can help swimming coaches to classify their swimmers and enable them to suggest what might be the swimmers’ most appropriate stroke (talent identification). 相似文献

我国优秀女排队员移动拦网技术动作解析 总被引：1，自引：0，他引：1
1前言近年来世界排球大赛的实践表明，拦网已从单一的防守技术转变为攻防兼备的制胜技术之一。拦网水平的高低不仅直接影响比赛的胜负，而且也是衡量一支球队技战术水平的重要标志之一，因此，备受国内外教练员和科研工作者的关注。长期以来，有关拦网技术的研究，仅限于现场统 相似文献

Background: Motor skill (MS) competence is an important contributing factor for healthy development.Purpose: The goal was to test the effectiveness of primary school physical education (PE) on MS and physical fitness (PF) development.Methods: Three classes (n?=?60, aged 9.0?±?0.9) were randomly assigned to three diverse conditions during a school year: two PE lessons/week (PE-2), three PE lessons/week (PE-3), and no PE lessons control group (CG). BMI, skinfolds, PF (9-min run/walk, sit-up, modified pull-ups), gymnastics, soccer, handball, basketball and track-and-field skills were evaluated. Effect sizes (d) were reported as magnitude of change.Results: Skinfolds significantly increased only in CG (d?=?1.21). PF composite z-scores improved in PE-3 (d?=?0.61), but decreased in PE-2 (d?=?0.57), and had no changes in CG. Statistically significant improvement was verified in gymnastics and handball skills in both experimental groups (gymnastic: d?=?2.95 and d?=?2.61 for PE-3 and PE-2, respectively; handball: d?=?1.87 and d?=?0.57 for PE-3 and PE-2, respectively), and no changes were seen in CG. In soccer, there were improvements only in the PE-3 (d?=?0.55), and in basketball only in PE-2 (d?=?0.46). There were no changes in any group for track-and-field skills.Conclusions: PE programs can effectively promote PF and MS development. 相似文献

体医融合是健康中国战略实施的关键技术,为加快推进我国体医融合,促进全民科学健身与全民健康深度融合,基于布迪厄场域论,以“场域—资本—惯习”三要素为逻辑主线,对我国体医融合的实然困境与应然进路进行分析。体医融合实然困境包括：体育与医疗的结构差异、关系孱弱与体医融合的生成障碍,形成体医融合的场域壁垒;医疗部门经济资本受损、体疗制度资本乏力、复合型人力资本匮乏造成体医融合资本制约;传统医疗文化及医疗技术依赖,固化体医融合惯习。提出构建大健康网络, 打破体医融合场域壁垒;改革经济资本走向、完善制度资本、加强复合型人力资本培养,优化体医融合资本;消除体医融合惯习误识、摈除医疗技术依赖惯习的应然进路。 相似文献

通过对常州市公共体育场馆活动开展状况调查,发现市民认为公共体育场馆应该提供的公益性体育服务项目排在前三位,依次是:健身咨询、健身辅导及健身培训,多数市民健身趋向于公益性服务;体育场馆提供公益性体育服务的时间主要集中在早晨及中午的营业空闲时段,提供公益性体育服务的项目几乎涵盖了目前开展的所有经营项目。提出整合公共场馆的各种资源,培育公共体育场馆的消费主体,构建公共体育场馆运营中提供公益性体育服务的价值补偿机制等建议。 相似文献
