Fitness and health benefits of team handball training for young untrained women--A cross-disciplinary RCT on physiological adaptations and motivational aspects

Purpose: The present study evaluated the effects of regular participation in small-sided team handball training on body composition, osteogenic response, physical performance, and cardiovascular risk factors, as well as well-being and motivation, in young untrained women.Methods: Twenty-eight untrained 20- to 30-year-old women were randomized to a handball training group(HG; n = 14, height 170 ± 5 cm, weight 73 ± 11 kg, VO_(2peak) 37.7 ± 4.1 mL/min/kg) that trained 1.7 ± 0.3 times per week over 12 weeks(70 min 4 v 4 handball sessions) or an inactive control group(CG; n = 14, 169 ± 5 cm, 71 ± 12 kg, 38.1 ± 3.7 mL/min/kg). Physiological and psychological and motivational training adaptations were assessed pre-and post-intervention by dual-energy X-ray Absorptiometry(DXA) scans, blood sampling, physical tests, and questionnaires.Results: The average heart rate(HR) over all training sessions was equal to 85% ± 6% HR_(max). Between-group intervention effects were observed in favor of HG for muscle mass(2.1%, p = 0.024), proximal femur bone mineral density(0.8%, p = 0.041), Yo-Yo IE1 intermittent endurance test level 1(IE1) performance(35%, p < 0.001), and incremental treadmill test performance(11.5%, p = 0.003), but not total fat mass(p = 0.176),mean arterial blood pressure(p = 0.328), resting HR(p = 0.219), or blood lipids(p = 0.298—0.854). In CG, no changes were observed in any of the measured physiological variables after the training period. Compared to CG, HG had an increase in intrinsic motivation(p < 0.001) and in the well-being subscale "energy"(p = 0.010).Conclusion: Participation in regular recreational team handball training organized as small-sided games has marked beneficial effects on physical performance, musculoskeletal fitness, well-being, and motivation in untrained young women.

Correlations of Handgrip Strength with Selected Anthropometric Variables and Flexibility Measure in Indian Inter-university Handball Players

The purpose of this study was of two-fold： firstly to estimate the handgfip strength oflndian inter-university handball players and, secondly to search the correlations of it with selected anthropometric variables and flexibility measure. To serve this purpose, a total of eight anthropometric variables, such as height, weight, body mass index, upper arm length, forearm length, total arm length, hand length and hand breadth, flexibility measure such as, sit and reach test, and right and left handgrip strength were measured on purposely selected 150 Indian inter-university handball players aged 18-25 years collected from the inter-university competition held in Guru Nanak Dev University, Amritsar, India during September, 2013. An adequate number of controls （n = 102） were also taken from the same place for comparisons. The results showed statistically significant between-group differences （P 〈 0.006-0.001） among the male and female handball players and controls in all the variables studied. Statistically significant positive correlations （P _〈 0.023-0.001） of both right and left handgrip strength were found with all the variables studied, except BMI, in Indian inter-university handball players. In conclusion, it may be stated that handgrip strength may be used as one of the indicating factors for physical strength as well as the flexibility measure of the handball players.

The Effect of Functional Training on the Performance of Female Handball Players’Shooting Skills

A randomized grouping experiment was conducted to study the effect of 8-week functional training on shooting performance of Beijing female handball players.According to the athletes’FMS(functional movement screening)scoring results,they were randomly divided into 2 groups.The experimental group adopted an 8-week functional training,aiming at strengthening their core strength,joint stability,and the power chain of shooting techniques.The control group adopted the traditional strength training mode.ANOVA(analysis of variance)was adopted to analyze the different performance of the athletes from two groups on their FMS scores,distances of throwing,and 7-meter shooting speed before and after the experiment.The results show that:(1)the total FMS scores of the experimental group athletes have been increased more significantly than those of the control group,and the injuries per capita has been significantly reduced;(2)the athletes in the experimental group have more significantly improved performance in handball throwing and 7-meter shooting speed than those in the control group.It shows that 8 weeks of functional training may effectively improve the physical function of Beijing female handball players and their performance in two special skills of handball throwing and shooting speed.

运用文献资料调研、数理统计以及对比分析等方法,对第29届北京奥运会男、女手球项目比赛的38项技术统计数据进行比较与分析,其目的是探索手球项目的制胜因素以及对我国该项目发展的启示。研究结果表明:1)世界手球项目比赛胜、负影响最大的关键性因素有:射门技术指标、突破配合、犯规技术指标以及门将技术指标四大方面,其中,男子手球项目上:"射门"方面有10项,"突破配合"方面有4项,犯规方面有1项,"门将"方面有6项;女子手球项目上:"射门"方面有7项,"突破配合"方面有6项,"犯规"方面有1项,"门将"方面有7项。2)经综合分析可知,我国男子手球队与世界整体水平相比,劣势指标中,差距较大的有14项(P<0.01或P<0.05),差距较小的有16项(P>0.05)优势指标有8项(除罚出场2min为负,其他指标均值差为正),劣势指标项占78.95%,表明我国男子手球队的整体竞技实力与世界强队整体水平还有很大的一段差距。3)经综合分析可知,我国女子手球队与世界整体水平相比下,劣势指标中,差距较大的有15项(P<0.01或P<0.05),差距较小的有15项(P>0.05),优势指标有8项(除罚出场2min为负,其他指标均值差为正),劣势指标项占78.95%,表明我国女子手球队的整体竞技实力与世界强队还有一定的差距。研究认为,我国男子与女子手球队的整体水平还处于世界二、三流水平上。

我国手球运动训练存在的主要问题

采用面访调查、专家调查及问卷调查法,分析我国手球运动训练存在的主要问题。认为:在强对抗中合理运用基本技术能力、运动员的身体素质和身体能力差是制约我国手球运动训练水平的因素。导致我国手球训练质量不高主要有教练员与运动员两方面的原因。教练员主要反映在理论水平、敬业精神方面;运动员主要反映在敬业精神和自觉训练方面。

中国女子手球运动员月经异常的内分泌特点

为探索女子手球运动员月经异常的内分泌机制,以中国女子手球运动员为研究对象,测试月经正常和月经异常运动员的体脂%、血FSH、LH、E2、GH、Leptin、T、C、Ca、ACTH水平。结果:1)月经异常运动员比月经正常运动员的体脂%低。2)月经异常运动员比月经正常运动员Leptin、GH、FSH、LH、PRO、E2明显降低,而ACTH、C、T无显著差异。3)Leptin与GH、体脂%正相关,与C负相关;FSH与LH、E2和Ca正相关。4)月经异常内分泌特点有个体差异。结论:月经异常运动员HPO轴受到一定程度抑制,其原因与体脂、FSH、LH、PRO、E2、Leptin、GH水平偏低有关。推测血液Leptin过高或过低是导致运动员月经异常的重要原因,引起女子手球运动员月经异常的内分泌机制有个体差异,运动机能受月经异常影响较弱。

我国转项成才手球运动员研究

以参加第十二届全运会比赛的手球运动员为研究对象,对我国转项成才手球运动员展开研究。转项成才手球运动员在我国一线优秀手球运动员中所占比例较高,且女性稍多于男性。这些转项成才运动员来自9个不同类型的运动项目,并以技战能主导类篮球项目的运动员居多。转项成才运动员在转入手球运动训练前大都具有1年以上的训练经历,并有少数运动员达到了二级运动员的水平。转项成才运动员在成才年限的总体水平上要优于非转项运动员,特别是在健将级运动员的培养上更具优势。转项运动员在比赛制胜关键技术上占优,表明转项运动员的竞技能力要优于非转项运动员。我国手球运动中转项成才运动员的大量存在,源于我国手球运动人才严重不足、我国手球运动竞技水平下滑;不同项目间运动技能的迁移、转项成才运动员转项前运动等级水平低和一定的专项训练经历及转项运动员具备异项潜才特质为转项成功提供了动因。转项成才手球运动具有竞技水平突出、培养成才所需时间较短和高级别运动员成才人数多的优势,但同时也存在手球专项技术的综合应用能力不足、手球运动操作思维缺乏创造性和竞技潜力不足的劣势。国外手球运动强国的高水平俱乐部和国家队中极少有转项运动员,并自始至终坚持非转项成才手球运动员的培养。我国应进一步完善手球后备人才培养体系,坚持非转项手球运动人才的培养和提高手球训练的科学化水平。
