采用运动现场对60名9～12岁游泳运动员进行个体乳酸阈(ILT)测定,结果显示:9～12岁游泳运动员的ILT在2.00～3.10 mmol/L之间,100 m自由泳后血乳酸峰值出现在7.1～12.6 mmol/L范围内,均较成年运动员值偏低,反映了少年运动员机体代谢的特异性,提示在实践中应根据少年运动员生理特点合理安排运动训练与教学. 相似文献

广东省少儿游泳运动员赛前焦虑状态的研究 总被引：1，自引：0，他引：1
运用SCAT—C和状态一特质焦虑量表STAIx—Jx—Ⅱ两种量表,对参加1995年广东省少年儿童游泳锦标赛的游泳运动员进行测试。结果发现:游泳运动员赛前焦虑状态水平,儿童高于少年;女子赛前焦虑水平和运动成绩都高于男子,这与女子心理和生理方面的特点有关。 相似文献

本研究以8名青少年中长距离游泳运动员为研究对象,分为2组,在以中低强度有氧为主的训练阶段A组4人穿插每周3次的力量训练,B组4人仅安排1次力量训练,在干预前后分别以5×200m递增负荷测试评价各区域运动能力的变化,探讨力量训练对运动能力的影响。研究表明,力量干预后,A组运动员最大摄氧量强度(BLa=8mM)对应的游速平均提高幅度为3.15%,高于B组运动员的0.65%;无氧阈强度(BLa=4mM)对应的游速A组提高幅度为1.87%,低于B组运动员的4.07%;低强度有氧(BLa=2mM)对应的游速提高幅度为0.51%,与B组运动员的0.18%相近。上述结果提示,为期2个月、每周3次的力量训练干预对运动员最大摄氧量强度运动能力表现出较好的改造效果,但对无氧阈及以下强度的运动能力未表现出额外效果。 相似文献

This meta-analysis aims to determine the effects of regular swimming on bone mineral density (BMD) in young adults (18–30 years). A systematic search was performed in Pubmed, SPORTDiscus and the Cochrane Library from the earliest possible year to March 2016. Swimmers were compared to non-athletic controls (CG) and to high-impact athletes (HIGH). Effect sizes with the Hedges g in random effects models were developed. Fourteen studies met the inclusion criteria and were included in the meta-analyses. Swimmers presented similar BMD values to CG in whole-body (g = ?0.20; P = 0.251), femoral neck (g = ?0.05; P = 0.818) and lumbar spine (g = 0.18; P = 0.492); and lower BMD in the whole-body (g = ?1.21; P < 0.001), femoral neck (g = ?1.51; P < 0.001) and lumbar spine (g = ?0.84; P = 0.017) than the HIGH. For the whole-body differences, the higher the latitude the smaller the differences between swimmers and HIGH (B = 0.10; P = 0.001). For the femoral neck differences, age also seemed to reduce the differences between groups (B = 0.19; P = 0.020). Young adult swimmers present similar BMD values than CG and lower values than HIGH. 相似文献

Abstract This research compares the prevalence of hypertension in a group of adult masters swimmers with an age and sex matched cohort from the 2008 NHANES (National Health and Nutrition Examination Survey), used to represent the general population in the United States. Masters swimmer data were obtained from a one-time survey of all United States Masters Swimming (USMS) members. Both datasets included demographics, drug therapy, diseases and health status. Characteristics of swimming sessions as well as perceptions of impact of medications on exercise were also collected from the USMS respondents. Of 1346 completed surveys from USMS respondents, 15.8% self-identified as having hypertension while 36.2% participants in the NHANES survey suffered from hypertension (P < 0.001). The two groups were well matched for age and gender but the USMS group was primarily Caucasian, higher income, higher education, and reported higher health status. In the USMS group, not only was hypertension less prevalent but those who suffered from hypertension took fewer medications (P = 0.04) to manage their hypertension than in the NHANES group. Additionally, The USMS group suffering from hypertension considered themselves healthier (P < 0.001) than the NHANES group. 相似文献
