- Determination of aerobic and anaerobic power in elite taekwondo athletes through a sport specific testPublication . Rocha, Fernando Paulo Sebastião; Costa, Aldo Filipe Matos Moreira Carvalho da; Brito, João Paulo Reis Gonçalves Moreira deCurrently, the modern taekwondo in the sporting competitive side requires a high volume and almost constant training intensity throughout the sports season. The specific physical assessment test mode can monitor the athlete's training status, giving specific guidance for the development of training, in addition to being an indicator of recognized potential for the prevention and detection of overtraining. It turns out that taekwondo athletes are subjected to physical evaluations with nonspecific tests, without any transfer to the form to the technical gesture level, and also in respect of the effort characteristic during training and competition. Thus, the primary purpose of this thesis was to determine the concurrent validity of using two assessment protocols of aerobic and anaerobic fitness in taekwondo athletes. A sample consisted of 17 male subjects older than 17 years from the Portuguese taekwondo national team participated in this study. The Bandal Chagui technique was selected to integrate both physical assessment protocols running against a punching bag. The 20m shuttle run test and the Wingate 30-second protocol test were both used as a criterion for aerobic and anaerobic evaluation, respectively. The aerobic-specific test was based on the progressive test of maximum effort proposed by Sant´Ana and collaborators, having been rated the maximal oxygen uptake (VO2max). The anaerobic-specific test was based on a protocol for 30 seconds, where the athletes had to perform the maximum number of kicks (Bandal Chagui) and with maximum force against a punching bag. The impact force of Bandal Chagui technique was evaluated in both protocols through a piezoelectric sensor. Here are some of the key findings: (i) There was a correlation between the two aerobic tests; (ii) The model presented for estimating VO2max with a specific test explains 74% of the observed variability in VO2max; (iii) The anaerobic-specific test had a level of agreement with the Wingate test, conferring specificity for the evaluation of anaerobic fitness.
