Brush more difficult: study says athletes have broken world records in slow-speed Rio Olympic Games, the athletes-IT information
Rio Olympic Games in Beijing August 8 August 7 in the men's weightlifting 56 kg category final, long qingquan of China with a total score of 307 kg results once again break the world record. For years, players of the Olympic results continue to refresh the world record, on the one hand human strength, speed, endurance is close to its limit, on the technical, cultural and other factors constantly expand humanity's ultimate limits.
According to the Scientific American website reported chalilaosi·waxilakesi in 1896, Greece won for the first time in modern Olympic Marathon time was 3 hours, 18 minutes, but today, this result into the Boston Marathon are not qualified. London's Brunel University Sports, said Mark Williams, a Professor of health and Sport Sciences, people's overall performance is on the rise, this depends to a large degree of fitness, conditioning, understanding and attention to diet and nutrition.
The modern Olympic Games, each game world record has greatly improved. But this will be subject to global conflict, social change, technological progress and the impact of rule changes and other factors. France national sports and physical education Institute (INSEP) jiefuluoyi·beiteluo said that during the cold war, Soviet-style hard science research satellites designed to engage players using illegal stimulants, so long that time some world record beyond, such as the men's hammer throw record until 1986 by the Soviet hammer thrower broke Youli·xiedihe in the European Championships.
Social changes also help athletes perform better, such as the women's Marathon. People used to think that women don't run until the 1984 United States Olympic Games in Los Angeles before the women's Marathon into a special game. Technological breakthrough also plays an important role. In the 1968 United States Olympic Games in Mexico City, Dick forsbury created back-style high jump and won the gold medal, while not breaking the world record, but after the players after training for several years, eventually lifting record for the high jump.
Berthelot said that breaking the world record speed in reaching a peak in 1988. Along with the close human physiological limits, plus the International Athletics Federation to combat doping, breaking the world record speed is also slow. There are exceptions, but this trend, such as during 2008-2009 allows using the polyurethane swimsuits, this swimsuit "human technology" continues to create new swimming record.
Human movement is there a limit? People send questions. In fact, the sports abilities of the human body is like a horse, unlimited run at the same time there is a Bridle Reins, which is our body's physical structure. Mechanical and biological methods of scientists are always trying to make all kinds of budgets, to determine the body's limits: limits of 100-meter dash in 9 seconds; limit of 110-meter hurdles is 12 seconds 38; limit of 8.96 meters in the long jump ... ... However, humans have always erupted at a critical moment the infinite potential, long qingquan's performance once again proves that – the nervous system cannot be fully mobilized muscles work, but he broke the power of muscle fibers, for the Chinese team won a gold!
刷成绩更难：研究称运动员打破世界纪录速度在放慢 - 里约

北京8月8日电 在8月7日的里约奥运会男子举重56公斤级决赛中，中国选手龙清泉以总成绩307公斤的成绩再次打破世界纪录。多年来，选手们的奥运成绩不断刷新世界纪录，一方面是人类的力量、速度、耐力正在接近极限；另一方面，技术、文化等因素也在不断拓展着人类的最终极限。
据《科学美国人》网站近日报道，查理劳斯·瓦西拉科斯在1896年的希腊奥运会上第一次赢得现代马拉松比赛，时间是3小时18分，而在今天，这个成绩连进波士顿马拉松都不够格。英国伦敦布鲁内尔大学体育、健康与运动科学教授马克·威廉姆斯说，人们的总体表现呈上升趋势，这在很大程度取决于人们对健身、调节、饮食与营养的理解和重视。
现代奥运会中，每项比赛的世界纪录都已极大提高。但这种上升会受到全球冲突、社会变化、技术进步和规则变化等多种因素的影响。法国国家运动和体育学院（INSEP）杰弗罗伊·贝特洛说，在冷战期间，前苏联把研究卫星式的硬科学用来培养运动员，使用非法兴奋剂，因此那段时间的一些世界纪录长期无法超越，比如男子链球纪录，直到1986年才由前苏联链球运动员尤里·谢迪赫在欧洲锦标赛上打破。
社会变化也有利于运动员表现更好，比如女子马拉松。以往人们认为女性不适合长跑，直到1984年的美国洛杉矶奥运会上，才将女子马拉松纳入专项比赛。技术突破也起了重要作用。在1968年美国墨西哥城奥运会上，迪克·福斯贝利创造了背越式跳高赢得了金牌，虽然并未打破世界纪录，但经过选手们多年训练后，最终大大提升了跳高纪录。
贝特洛指出，打破世界纪录的速度在1988年达到顶峰。随着人类不断接近生理极限，加上国际田径联合会打击兴奋剂，打破世界纪录的速度也在放慢。但这一大趋势下也有例外，比如在2008到2009年间允许使用聚氨酯泳衣，这种来自泳衣的“人为技术”不断创造出新的游泳纪录。
人体运动到底有没有极限？人们总会发出这样的疑问。事实上，人体的运动潜能就像是一匹骏马，无限奔跑的同时总有一条勒住它的缰绳，这便是我们身体的生理结构。科学家总是试图通过力学、生物学等方法做出种种预算，来确定人体极限：100米短跑的极限是9秒；110米栏的极限是12秒38；跳远的极限为8.96米……不过，人类总是在关键时刻爆发出无限的潜能，龙清泉的运动表现再次验证了这一点——神经系统无法动员百分之百的肌肉工作，但他的肌纤维的确爆发出了强大的力量，为中国队摘得一金！
