采用问卷调查、实验研究和数理统计等方法,对中国健美操协会于2005年和2009年分别推出的第二套和第三套《全国健美操大众锻炼标准》中的成人组1～5级有氧操部分的运动强度及规律进行研究。结果表明,第二套和第三套《全国健美操大众锻炼标准》成人1～5级有氧操部分运动中的强度变化呈渐增型趋势,两套《全国健美操大众锻炼标准》1～4级动作心率都在健身负荷的心率有效价值区间(60%MHR～80%MHR),符合全民健身的HR锻炼标准,两套《全国健美操大众锻炼标准》1～5级同级别之间运动强度不存在显著性差异,主观感觉方面第三套《全国健美操大众锻炼标准》总体优于第二套,为更好、更安全地推广大众健美操奠定了一定的基础,也拓宽了健美操等级套路的选择范围。 相似文献

采用《饮酒及重要疾病调查问卷》对受试者进行筛选,确定191名60-67岁之间老年受试者,采用《身体锻炼调查问卷》对其锻炼情况进行收集,采用问卷方式对其老化态度和一般自我效能感进行测量,采用计算机实验方式对其执行功能进行了测试。结果发现,体育锻炼不仅能够直接改善老年群体的执行功能相关水平,延缓认知衰老,同时还可以通过一般自我效能、老化态度间接促进老年人执行功能的改善和延迟衰退;每周至少锻炼3-5次,每次1小时以上,坚持3-6年,才会对老年人一般自我效能产生显著地促进作用;每周进行3次及以上的锻炼频率,单次锻炼时间1小时以上,坚持3-6年,便会对老年人的老化态度产生积极效应。 相似文献

Exercise intensity and metabolic response in singles tennis 总被引：5，自引：0，他引：5

The aim of this study was to determine exercise intensity and metabolic response during singles tennis play. Techniques for assessment of exercise intensity were studied on-court and in the laboratory. The on-court study required eight State-level tennis players to complete a competitive singles tennis match. During the laboratory study, a separate group of seven male subjects performed an intermittent and a continuous treadmill run. During tennis play, heart rate (HR) and relative exercise intensity (72 +/- 1.9% VO2max; estimated from measurement of heart rate) remained constant (83.4 +/- 0.9% HRmax; mean +/- s(x)) after the second change of end. The peak value for estimated play intensity (1.25 +/- 0.11 steps x s(-1); from video analysis) occurred after the fourth change of end (P< 0.005). Plasma lactate concentration, measured at rest and at the change of ends, increased 175% from 2.13 +/- 0.32 mmol x l(-1) at rest to a peak 5.86 +/- 1.33 mmol x l(-1) after the sixth change of end (P < 0.001). A linear regression model, which included significant terms for %HRmax (P< 0.001), estimated play intensity (P < 0.001) and subject (P < 0.00), as well as a %HRmax subject interaction (P < 0.05), accounted for 82% of the variation in plasma lactate concentration. During intermittent laboratory treadmill running, % VO2peak estimated from heart rate was 17% higher than the value derived from the measured VO2 (79.7 +/- 2.2% and 69.0 +/- 2.5% VO2peak respectively; P< 0.001). The %VO2peak was estimated with reasonable accuracy during continuous treadmill running (5% error). We conclude that changes in exercise intensity based on measurements of heart rate and a time-motion analysis of court movement patterns explain the variation in lactate concentration observed during singles tennis, and that measuring heart rate during play, in association with preliminary fitness tests to estimate VO2, will overestimate the aerobic response. 相似文献

为了解第八届全国少数民族健身操的运动强度,在比赛前一天的热身赛中,抽取11个参赛队的运动员共51人作为研究对象。通过测试运动员安静、运动后即刻、运动后4、5、6分钟的脉搏来评定运动员的身体机能,运动强度和运动后的恢复情况。研究结果显示：成年人安静心率63.7±6.8次/分钟,运动后即刻心率达到164.8±24.97次/分钟,强度达到中高强度,运动后6分钟心率为75.5±20.8次/分钟,基本恢复安静,心率比安静时高,可能与当时运动现场的环境有关。少年对主要是指山东队,其运动员的安静心率为68.2±3.6次/分钟,运动后即刻心率达到120±29.4次/分钟,强度属于中低强度,运动后6分钟心率为70.5±4.7次/分钟,心率基本恢复正常。 相似文献

Abstract The purpose of this study was to determine the ability of individuals with a cervical spinal cord injury to achieve and sustain a cardiorespiratory training intensity during wheelchair rugby. Nine wheelchair rugby players completed a continuous peak exercise test on a SciFit Pro I arm ergometer with stage increases each minute to determine peak heart rate and power output. Approximately one week after peak exercise testing, heart rate was recorded (every 5 s) during three regularly scheduled rugby training sessions. Data were analysed to determine the number of continuous minutes that participants spent above 70% of heart rate reserve under various rugby training activities. The percent of time spent at or above 70% heart rate reserve varied across participants and conditions. Continuous pushing was the least variable training condition among participants with the sample averaging greater than 73% of time above the target heart rate. Scrimmage training was highly variable across participants with a range of 0% to 98% of time above the criterion. Results of this study indicate that wheelchair rugby training enables some participants to reach a training intensity associated with improved cardiorespiratory fitness, and that the type (or kind) of training activity dictates the extent to which individuals sustain such a threshold. 相似文献

目的:研究音乐渐进放松配合音乐心率训练对运动性疲劳消除的影响,并探讨其与传统恢复方法的比较优势。方法:15～22周岁的男运动员共36名,进行为期7天的同等负荷量度的实验训练,中间休整1天,前3天每天早上测量晨脉,运动前测量RPE值、大腿围、小腿围。训练中记录RPE值,运动后即刻测量心率、大腿围、小腿围。测量结束后采用5min传统的整理运动恢复练习,之后再次测量心率、大腿围、小腿围。后3天每天运动前测量RPE值、大腿围、小腿围。训练中记录RPE值,运动后即刻测量心率、大腿围、小腿围。测量结束后采用5min的音乐渐进放松配合音乐心率训练恢复,之后再次测量心率、大腿围、小腿围和RPE值。结果:与运动后即刻相比,音乐渐进放松配合音乐心率训练干预后RPE值下降的幅度在23.77%～25.41%;大、小腿围减少的幅度分别在1.07%～1.16%和0.47%～0.64%;与传统恢复相比,音乐疗法后RPE值比传统恢复法有所下降,下降幅度为1.15%～1.76%;大、小腿围减少幅度分别在0.07%～0.18%和0.16%～0.22%。结论:音乐渐进放松配合音乐心率训练对运动疲劳的恢复有积极作用;与传统恢复法相比,音乐疗法更有利于促进心血管系统、中枢神经系统和心理状态的恢复,且经济实用、易于推广。 相似文献

目的：本次研究拟测量不同级另0篮球裁判员在省青少年比赛中的心率数据，研究分析篮球裁判员在比赛中的心率分布特征，以了解其运动强度大小和特点。验证实验的可行性，为今后更深入的研究提供理论依据。对象及方法：在江苏省青少年篮球比赛期间，使用遥测心率表记录21名不同级别裁判员比赛中的心率。结果：实验得出篮球裁判员在省青少年比赛中平均心率主要分布于130—149次／分之间，约占总体的59％；裁判员在比赛中的最高心率超过200次／分以上者最多（约33％）。使用Karvone公式法评定时，半数以上裁判员的平均运动强度处于50％-69％的区间。最大心率法与Karvone公式法在评定时存在偏差，Karvolle公式法更客观的反映临场运动强度。 相似文献
