Effect of repeat-sprint training in hypoxia on post-exercise interleukin-6 and F2-isoprostanes     

Paul S. R. Goods  Brian Dawson  Grant J. Landers  Christopher J. Gore  Kevin Croft  Peter Peeling 《European Journal of Sport Science》2016,16(8):1047-1054

This investigation examined the oxidative stress (F₂-Isoprostane; F₂-IsoP) and inflammatory (interleukin-6; IL-6) responses to repeat-sprint training in hypoxia (RSH). Ten trained male team sport athletes performed 3(sets)*9(repetitions)*5?s cycling sprints in simulated altitude (3000?m) and sea-level conditions. Mean and peak sprint power output (MPO and PPO) were recorded, and blood samples were collected pre-exercise, and again at 8 and 60?min post-exercise. Both MPO and PPO were significantly reduced in hypoxia (compared to sea-level) in the second (MPO: 855?±?89 vs. 739?±?95?W, p?=?.006; PPO: 1024?±?114 vs. 895?±?112?W, p?=?.010) and third (MPO: 819?±?105 vs. 686?±?83?W, p?=?.008; PPO: 985?±?125 vs. 834?±?99?W, p?=?.008) sets, respectively. IL-6 was significantly increased from pre- to 1?h post-exercise in both hypoxia (0.7?±?0.2 vs. 2.4?±?1.4?pg/mL, p?=?.004) and sea-level conditions (0.7?±?0.2 vs. 1.6?±?0.3?pg/mL, p?d?=?0.80) suggesting higher IL-6 levels of post-hypoxia. F₂-IsoP was significantly lower 1?h post-exercise in both the hypoxic (p?=?.005) and sea-level (p?=?.002) conditions, with no differences between trials. While hypoxia can impact on exercise intensity and may result in greater post-exercise inflammation, it appears to have little effect on oxidative stress. These results indicate that team sport organisations with ready access to hypoxic training facilities could confidently administer RSH without significantly increasing the post-exercise inflammatory or oxidative stress response.  相似文献

用系统的观点探索高职专业建设     

范珍 《重庆职业技术学院学报》2006,15(1):11-13

用系统科学的观点分析,高职专业建设纵向可分为三个层次:理论层面、设计层面、操作实施层面。操作实施层面从横向又可分专业建设核心体系、保障体系、评价反馈体系三个子系统。高职专业建设是一项系统工程,必须从全方位、多维的角度展开,只有专业建设的各要素整体优化,才能达到综合的、整体的效益。  相似文献   

Altitude and wind effects on long jump performance with particular reference to the world record established by Bob Beamon     

A.J. Ward‐Smith 《Journal of sports sciences》2013,31(2):89-99

An analysis of long jump performance, including both the approach and aerial phases, is applied to Bob Beamon's legendary leap at the Mexico City Olympic Games of 1968. It is shown that the combined effects of altitude and wind assistance yielded an increment in the length of the jump of about 31 cm, compared to a corresponding jump at sea level under still air conditions. The main factor is shown to be the increased sprinting speed attained under favourable conditions of wind and altitude.  相似文献

高原训练对促红细胞生成素（EPO）的影响   总被引：1，自引：0，他引：1  

苏文涛 《湖北体育科技》2008,27(5):540-541

高原训练作为一种能提高运动员运动成绩的有效手段,广泛被教练员们所采用。其主要的作用机制是通过提高血中促红细胞生成素（erythropoietin,EPO）的含量,使红细胞的生成增加,从而增强机体携带氧的能力,使运动能力得到提高。为此,本文将高原训练对促红细胞生成素的影响加以综述,以便更好的指导运动训练。  相似文献   

Altitude training in endurance running: perceptions of elite athletes and support staff     

Gareth Turner  Barry W Fudge  Jamie S M Pringle  Neil S Maxwell  Alan J Richardson 《Journal of sports sciences》2019,37(2):163-172

This study sought to establish perceptions of elite endurance athletes on the role and worth of altitude training. Elite British endurance runners were surveyed to identify the altitude and hypoxic training methods utilised, along with reasons for use, and any situational, cultural and behaviour factors influencing these. Prior to the 2012 Olympics Games, 39 athletes and 20 support staff (coaches/practitioners) completed an internet-based survey to establish differences between current practices and the accepted “best-practice”. Almost all of the athletes (98%) and support staff (95%) surveyed had utilised altitude and hypoxic training, or had advised it to athletes. 75% of athletes believed altitude and hypoxia to be a “very important” factor in their training regime, with 50% of support staff believing the same. Athletes and support staff were in agreement of the methods of altitude training utilised (i.e. 'hypoxic dose’ and strategy), with camps lasting 3–4 weeks at 1,500–2,500 m being the most popular. Athletes and support staff are utilising altitude and hypoxic training methods in a manner agreeing with research-based suggestions. The survey identified a number of specific challenges and priorities, which could provide scope to optimise future altitude training methods for endurance performance in these elite groups.  相似文献

贵州省不同海拔地区居民参加体育锻炼的差异研究     

甘春龙  屈进 《福建体育科技》2013,(2):20-21,24

目的:对贵州省不同海拔地区居民体育锻炼的现状进行调查研究,为不同海拔地区居民科学健身,提高生活质量提供依据。方法:采用"多阶段分层随机抽样"的方法抽取研究对象进行问卷调查。结论:(1)高原地区居民参加体育锻炼的参与程度较高,呈现高原>亚高原>平原的特征,但在参加体育锻炼的质量上却表现出相反的特征,与高原、亚高原地区相比,平原地区表现为参与频度高、持续时间长、体育锻炼强度适中。(2)不同海拔地区居民在体育锻炼场所选择、体育锻炼的目的和需求方面存在一定的差异,与不同海拔地区的自然环境气候差异有一定的关系。建议:在全民健身活动中应考虑不同自然环境气候的差异,研究制定科学有效、简便易行、适合不同海拔地区居民的健身方法,更加科学地指导居民健身,提高居民的体质水平。  相似文献
