普通男大学生有氧能力监测指标研究   总被引:1,自引:0,他引:1  
本文目的旨在筛选我国大学生体质有氧能力监测指标,为其健康测试指标体系提供理论依据。方法:将实验对象分为建模组和评估组,以VO2max和AT作为效标,将建模组1000m跑、12min跑、20m往返跑、台阶试验指数的测试结果与效标进行相关性分析,筛选指标;而后以筛选的指标为自变量,VO2max为因变量,建立预测VO2max的回归模型进行线性回归分析,再通过评估组对VO2max预测模型进行实效性评估,以确定指标的优良性。结果:(1)12min跑和20m往返跑不仅与VO2max之间呈高度相关性,而且与VT之间也表现出较高的相关性;1000m跑与VO2max和VT之间相关性很低;台阶试验指数与VO2max和VT之间均无相关性。(2)以12min跑、20m往返跑建立预测VO2max的回归模型拟合优度均较高,预测效果通过相关性检验和配对t检验显示实效性均较好。结论:(1)12min跑不仅是一项能有效评价大学生有氧能力的指标,而且还是一种科学的有氧健身方式;(2)20m往返跑也可以有效地反映大学生有氧能力水平;(3)1000m跑和台阶试验指数不适合作为评定大学生有氧能力的指标。  相似文献

12min跑评定大学生耐力素质的研究   总被引:2,自引:1,他引:1  
1 问题的提出12 m in测验法 ,是 2 0世纪 70年代初由美国的库珀参照前人布·巴尔克定时间、测跑距的方法而倡始的。布·巴尔克最初发现了 15 m in跑程同 V O2 max的关系密切 ,倡导了15 min测验法。后来 ,巴尔克的学生库珀又做了进一步的研究。库珀在对 6~ 2 0 min不断改变时间的反复实践中发现 ,12 min跑程同 V O2 m ax的相关系数最大 ( n=115 ,r=0 .897) ,且 V O2 m ax水平的持续时间较长 ,能充分反映有氧代谢能力。1975年 ,日本学者浅见俊雄对 76名大学生进行了 12 min跑的实际调查 ,得出了与库珀十分接近的结果 ( n=76 ,r=0 .…  相似文献

为探索一种简便有效的评价人体心血管系统功能的定量运动负荷方法,采用3种不同负荷的蹲起试验方法对30名普通大学生的累积、即刻心功指数与他们的VO2max进行相关性研究,以相关系数的大小来判别各自的效度。发现60s60次蹲起测得的心功指数与VO2max的相关系数最高,45s45次蹲起的心功指数次之,30s30次最低,而3种不同负荷方法各自的即刻心功指数与VO2max的相关性均高于累积心功指数。认为60s60次蹲起试验测试心功能的方法(即刻心功指数)简单实用、评价效度高、易于实施与控制,有望成为简便有效的评价人体心血管系统功能的定量运动负荷方法。  相似文献

目前,还未见有人对后退跑和走对人体心肺机能和能量代谢的影响进行较为详细研究的文章。为此,本文对这一问题进行探讨,其结果如下:受试者在跑台上进行6分钟的运动后,后退跑比相应向前跑速度均为160m·min~(-1)的NE、VO2、HR、血HL含量分别高出均113%、85%、49.5%、22.1%,并且具有非常显著性差异。而在每分钟增加2%的坡度运动至力竭时,向前跑(160m·min~(-1))比后退跑1(120m·min~(-1))的VE、VO2、HR、血HL要高,并且在显著性差异。这就提示我们要在机体康复期内,可用后退跑和走的练习来促进组织的修复,保持和提高心肺机能及部分肌肉的力量;而要最大限度提高心肺功能,挖掘体能的潜力时,还是以向前运动的训练为宜。  相似文献

大学生心功能评价指标的效度研究   总被引:9,自引:0,他引:9  
采用文献资料调研、体质测试、数理统计及逻辑分析等方法对当前测评大学生心血管功能指标的台阶试验、1000m(男)/800m(女)及3000m(男)/2400m(女)跑这3种方法的有效性及可操作性进行了探讨,并就台阶试验评价的两种计算方法即台阶指数与每搏功进行了比较研究,结果发现,1)台阶指数及其得分与1000m/800m及3000m/2400m跑成绩的相关性较低(P>0.05),1000m/800m得分与3000m/2400m跑得分、男生台阶指数、女生每搏功存在良好的相关关系(P<0.05);2)每搏功与台阶指数评价心肺功能的有效性均较低,每搏功的评价功能要优于台阶指数,但其存在明显的性别、地区等差异,有待进一步研究;3)12min跑或3000m/2400m跑测验是评价与提高学生心功能的有效手段,建议用其取代1000m/800m跑或台阶试验,以测评大学生心血管功能。  相似文献

Abstract

The aim of this study was to assess the validity of the multistage shuttle run test in predicting maximal oxygen uptake (VO 2 max) in athletes trained in sports with different physical demands. Over a 14-day period, 10 male long-distance runners (continuous high-intensity exercise) and 10 male squash players (intermittent high-intensity exercise) performed, in random order, the multistage shuttle run test and a maximal treadmill protocol of increasing elevation which elicited VO 2 max. Compared with direct measurement of VO 2 max, the shuttle run test significantly underpredicted the VO 2 max of the group of runners (n=10; P<0.01) and of the athletes as a whole (n=20; P<0.01). The correlation (r) between VO 2 max determined by the shuttle run test and by the treadmill protocol was 0.61 (P<0.05) for the squash players, 0.71 (P<0.05) for the runners and 0.67 (P<0.01) for the athletes as a whole. As the subjects represented athletes trained specifically in sports with different physical demands, this may explain why the correlations between the shuttle run test and direct measurement of VO 2 max are less robust than those reported in previous studies. Furthermore, our results indicate that there are sport-specific differences when predicting VO 2 max from the multistage shuttle run test.  相似文献

ABSTRACT

The purpose was to examine the feasibility of the 20m shuttle run test with music and to test its concurrent validity with the original 20m shuttle run test. A total of 386 adolescents (14.5±1.6 years old, 48.9% boys) participated in our study. A self-reported questionnaire was used to assess student’s perception about the 20m shuttle run test with music and the original and to assess perceived exertion. Participants performed randomly the 20m shuttle run test with music and original two weeks apart. Average and maximum heart rate were monitored with heart rate monitors. The 20m shuttle run with music was a feasible test for measuring cardiorespiratory fitness in adolescents. The concurrent validity showed mean differences of 5.1±14.6 for shuttles, 0.3±0.8 km/h for speed, 0.5±4.1 for stages, and 1.5±4.1 for VO2max (all p<0.001) in favour of the 20m shuttle run with music vs. the original 20m shuttle run test. Mean difference for the rating of perceived exertion was 0.4±2.5 points (p=0.003). No significant difference was found between boys and girls. In conclusion, the 20mSRT-music is feasible and presents a good concurrent validity in adolescents, independently of the sex and it will be an alternative and good approach to assess cardiorespiratory fitness.  相似文献

The aim of this study was to determine the incidence of subject drop-out on a multi-stage shuttle run test and a modified incremental shuttle run test in which speed was increased by 0.014m.s-1 every 20-m shuttle to avoid the need for verbal speed cues. Analysis of the multi-stage shuttle run test with 208 elite female netball players and 381 elite male lacrosse players found that 13 (+/-3) players stopped after the first shuttle of each new level, in comparison with 5 (+/-2) players on any other shuttle. No obvious drop-out pattern was observed on the incremental shuttle run test with 273 male and 79 female undergraduate students. The mean difference between a test-retest condition (n= 20) for peak shuttle running speed (-0.03+/- 0.01m.s-1) and maximal heart rate (0.4+/- 0.1 beats.min-1) on the incremental test showed no bias (P > 0.05). The 95% absolute confidence limits of agreement were 0.11m.s-1 for peak shuttle running speed and +/-5 beats.min-1 for maximal heart rate. The relationship (n= 27) between peak shuttle running speed on the incremental shuttle run test (4.22+/- 0.14m.s-1) and VO2max (59.0+/- 1.7ml.kg-1.min-1) was r=0.91 (P< 0.01), with a standard error of prediction of 2.6ml.kg-1.min-1. These results suggest verbal cues during the multi-stage shuttle run test may influence subject drop-out. The incremental shuttle run test shows no obvious drop-out patten and provides a valid estimate of VO2max.  相似文献

This study compares the motor skills and physical fitness of school-age children (6-12 years) with visual impairments (VI; n = 60) and sighted children (n = 60). The relationships between the performance parameters and the children's body composition are investigated as well as the role of the severity of the impairment. The degree of VI did not differentially affect the outcomes. Compared to their sighted peers, the children with VI scored lower on the locomotor and object control skills as assessed with the Test of Gross Motor Development-2, and the physical fitness (Eurofit) parameters of plate tapping, the standing broad jump, the modified 5 × 10-m shuttle run, and 20-m multistage shuttle run (20-MST). Their body mass and body fat indexes were inversely correlated with the standing broad jump and the 20-MST, but positively correlated with handgrip strength. Moreover, significant inverse correlations were found between their locomotor and object control skills on the one hand and plate tapping and the 5 × 10-m shuttle run on the other hand. Given the relatively high proportion (25%) of overweight/obese children within the VI sample, educators are recommended to promote health-related activities and help enhance motor skills in this population.  相似文献

The multistage 20 metre shuttle run test for aerobic fitness   总被引:18,自引:2,他引:16  
A maximal multistage 20 m shuttle run test was designed to determine the maximal aerobic power of schoolchildren, healthy adults attending fitness class and athletes performing in sports with frequent stops and starts (e.g. basketball, fencing and so on). Subjects run back and forth on a 20 m course and must touch the 20 m line; at the same time a sound signal is emitted from a prerecorded tape. Frequency of the sound signals is increased 0.5 km h-1 each minute from a starting speed of 8.5 km h-1. When the subject can no longer follow the pace, the last stage number announced is used to predict maximal oxygen uptake (VO2max) (Y, ml kg-1 min-1) from the speed (X, km h-1) corresponding to that stage (speed = 8 + 0.5 stage no.) and age (A, year): Y = 31.025 + 3.238 X - 3.248A + 0.1536AX, r = 0.71 with 188 boys and girls aged 8-19 years. To obtain this regression, the test was performed individually. Right upon termination VO2 was measured with four 20 s samples and VO2max was estimated by retroextrapolating the O2 recovery curve at time zero of recovery. For adults, similar measurements indicated that the same equation could be used keeping age constant at 18 (r = 0.90, n = 77 men and women 18-50 years old). Test-retest reliability coefficients were 0.89 for children (139 boys and girls 6-16 years old) and 0.95 for adults (81 men and women, 20-45 years old).(ABSTRACT TRUNCATED AT 250 WORDS)  相似文献

We investigated the associations of body fat percentage (BF%), objectively assessed moderate-to-vigorous physical activity (MVPA) and different types of physical activity assessed by a questionnaire with neuromuscular performance. The participants were 404 children aged 6–8 years. BF% was assessed using dual-energy x-ray absorptiometry and physical activity by combined heart rate and movement sensing and a questionnaire. The results of 50-m shuttle run, 15-m sprint run, hand grip strength, standing long jump, sit-up, modified flamingo balance, box-and-block and sit-and-reach tests were used as measures of neuromuscular performance. Children who had a combination of higher BF% and lower levels of physical activity had the poorest performance in 50-m shuttle run, 15-m sprint run and standing long jump tests. Higher BF% was associated with slower 50-m shuttle run and 15-m sprint times, shorter distance jumped in standing long jump test, fewer sit-ups, more errors in balance test and less cubes moved in box-and-block test. Higher levels of physical activity and particularly MVPA assessed objectively by combined accelerometer and heart rate monitor were related to shorter 50-m shuttle run and 15-m sprint times. In conclusion, higher BF% and lower levels of physical activity and particularly the combination of these two factors were associated with worse neuromuscular performance.  相似文献
