Do you love sports? Does that describe you?
Students in my classes have degrees in business management, finance, marketing and accounting, as well as, journalism, law, liberal arts, biology and history. Each student decided at some point that applying their degree in an area of sport would permit a combining of “loves”. Sport management degrees allow for this to occur!
The study was to investigate the variation in heart rate and oxygen consumption for Tae Kwon Do player during training performance. Ten male Tae Kwon Do players from Division I volunteered for the research. Experiment is performed and sample is collected for each player during training and competition period. The average age of the subject is 18.5±0.5 yr and the height is 171.7±1.8 cm ,and the weight is 62.8±0.7 kg The competition is of division I. During experiment, each subject runs on a treadmill machine at a gradient of 15% with an initial speed of 15 mph and 5 mph increase in speed every two minutes until complete exhaustion. Wireless heart recorder(POLAR) and Vmax29 gas analyzer are used to analyze heart rate and oxygen consumption. According to the statistical analysis on One-Way ANOVA Repeated Scheffe, the result s showed that: Tae Kwon Do player of HRmax was significantly different between group1 and group2 (195.3±2.8 vs. 185.5±2.1 bpm, p<.05). Tae Kwon Do player of the VO2max was significantly different between group1 and group2(53.1±2.0 vs. 45.1±0.5 ml/kg/min, p<.05). Tae Kwon Do player of the BMI was significantly different between group1 and group2 (21.3±0.5 vs. 27.5±0.3 kg/m, p<.05).
There are many basic principles of physical training an athlete must utilize for optimal results within their training program. The SAID Principle, the principle of specific adaptations to imposed demands is the foundation for sport specific training. Specific adaptations are known to take place in the human body in response to specific types of stimuli. The SAID Principle is the bases for physiological changes due to the imposed demands of the specific training stimuli.
Since tae-kwon-do has become an optical Olympic event competition in this event. Therefore, apart from keeping outstanding instructors and contestants, we must integrate the training and technology to elevate the training efficiency. The most important function for a successful coach is to help athletes to improve their athletic skill in a wide range of tasks from sequential development and mastery of basic skills for beginners, to the more specialized physical, technical, tactical and psychological preparation of elite athletes (Martens,1987) (Bompa,1983). Fast development of world-class high strength training and science has had a significant impact on the scientific training. Examples included weight control, not only covering the grading of various levels of athlete’s body weight but also balancing physical ability and health. Sport training is important even for excellent athletes. Only when their cardio respiratory function, energy expenditure and blood lactate system are well controlled can they show their potential and maintain high performance. This is very important to both coaches and athletes (Hiroyuki et al., 1999). Peaking, or the ability of an athlete to perform at peak performance during the main competition or games of the year, is also related to strength training.
The Study of Physiological Factors of Division I and II Basketball Players - Related to Training Time
The purpose of this research was to investigate the rest value and post exercise situation (5, 30, 60minute) of athletes with heart rate, oxygen consumption, and blood lactic acid. The objectives for this research were 20 volunteer Taiwanese basketball players, from university’s division I and II basketball players, whose average age was 21.6±1.83 years, average weight was 79.6±8.05 kg, and average height was 184.5±4.19 cm. During experiment, each subject rode the bicycle until completely exhaustion at a speed of 60 RPM and power of 150W that will increase by 30W for every two minutes until they feel totally exhausted. Observed the changes of heart Rate ,oxygen consumption and blood lactate from the physiological biochemical serum specimens when the players were in resting state and recovery state after exercising (5, 30, 60 min.). The indices were measured by the Polar heart rate recorder, Vmax29 analytical instrument, and blood lactate acid analytical instrument (YSI2300). All the information was analyzed by a single factor which changed and explained by the Schffee’ way, and the results as follow:
According to the literature there is mixed opinion as to whether restrictions in scholarships really affects the parity in college football. Mainly because is it difficult to measure competitiveness between teams. In the quest to maintain amateurism in football and college sports, corruption, cheating, and violation of rules have appeared to be a problem since the early 1900s. It is this author’s opinion that it is not the question of amateurism that is should be under debate. Rather, the sanctions set by the NCAA.
This study examines the undisciplined behavior of a player (Michelle), who creates an inappropriate environment in her team towards an achievement of a good performance; she suffers from psychological problems caused by a rough family environment; she is deprived of affection, stability, and is perhaps the breadwinner.
