Neuromuscular and technical abilities related to age in water-polo players

Testing is one of the important tasks in any multi-step sport programme. In most ball games, coaches assess motor, physical and technical skills on a regular basis in early stages of talent identification in order to further athletes’ development. The purpose of the study was to investigate anthropometric variables and vertical jump heights as a free throw effectiveness predictor in water-polo players of different age groups. Two hundred and thirty-six young (10–18 years) male water-polo players partitioned into three age groups underwent anthropometric variables’ measures and squat- and countermovement-jump tests, and performed water-polo free throws. Anthropometric variables, vertical jump heights and throw speed – as a proxy for free throw effectiveness – resulted different over age groups. Particularly, throw speed changed from 9.28 to 13.70 m · s^?1 (+48%) from younger to older players. A multiple-regression model indicated that body height, squat-jump height and throw time together explain 52% of variance of throw speed. In conclusion, tall height, high lower limb power and throwing quickness appeared to be relevant determinants for effective free throws. Such indications can help coaches during talent identification and development processes, even by means of novel training strategies. Further research is needed over different maturity statuses.  相似文献   

The History of the South East Asian Peninsular Games,1959–1975     

Peng Han Lim  Mohd Salleh Aman 《国际体育史杂志》2016,33(5):545-568

After the Second World War the Southeast Asian countries of Burma (1948), Laos (1954), Cambodia (1955), South Vietnam (1955), Malaya (1957), and Singapore (1959) sought independence from the British, French and Japanese colonialists. The first post Second World War and post-colonial biannual multisport Southeast Asian Games was held in Bangkok in 1959 among these countries (and Thailand) although they were relatively poor developing countries. Referring to official reports of the eight bi-annual SEAP Games and other sources of information this research studies how the organization of the eight SEAP Games since 1959 contributed to the nation building process of each country and shaped the political landscape. This was carried out by creating a national identity through sports in each country as well as creating a sense of regional cooperation during periods of war, shifting boundaries and identities. This was done through rituals to legitimize newly ascended constitutional monarchies and heads of states, national flags and athletes' national identity during competition. The SEAP Games also gradually opened avenues for women's participation similar to female athletes in the Olympic Games. It also provided opportunities for promising athletes to shine, improve and compete at higher levels at the Asian and Olympic Games.  相似文献
