A Feasibility Study of Kinematic Characteristics on the Upper Body According to the Shooting of Elite Disabled Archery Athletes
International Journal of Environmental Research and Public Health Article A Feasibility Study of Kinematic Characteristics on the Upper Body According to the Shooting of Elite Disabled Archery Athletes Tae-Whan Kim 1 , Jae-Won Lee 2, Seoung-Ki Kang 3, Kyu-Yeon Chae 4, Sang-Hyup Choi 5,* and Yong-Gwan Song 6,7,* 1 Korea Institute of Sport Science, Seoul 01794, Korea; [email protected] 2 Department of Special Physical Education, YongIn University, Yongin-si 17092, Korea; [email protected] 3 Graduate School of Education, YongIn University, Yongin-si 17092, Korea; [email protected] 4 Department of Physical Education and Training, Shanghai University of Sports, Shanghai 200438, China; [email protected] 5 Center for Sport Science in Jeju, Jeju 63819, Korea 6 Department of Marine Sports, Pukyong National University, Busan 48513, Korea 7 Department of Marine Design Convergence Engineering, Pukyong National University, Busan 48513, Korea * Correspondence: [email protected] (S.-H.C.); [email protected] (Y.-G.S.) Abstract: The purpose of this study is to compare and analyze the kinematic characteristics of the upper limb segments during the archery shooting of Paralympic Wheelchair Class archers (ARW2—second wheelchair class—paraplegia or comparable disability) and Paralympic Standing Class archers (ARST—standing archery class—loss of 25 points in the upper limbs or lower limbs), where archers are classified according to their disability grade among elite disabled archers. The participants of this study were selected as seven elite athletes with disabilities by the ARW2 (n = 4) Citation: Kim, T.-W.; Lee, J.-W.; and ARST (n = 3). The analysis variables were (1) the time required for each phase, (2) the angle of Kang, S.-K.; Chae, K.-Y.; Choi, S.-H.; inclination of the body center, (3) the change of trajectory of body center, and (4) the change of the Song, Y.-G. -

Editorial by Morten Wilmann, Chairman Dear Judges, When writing this editorial we are just up front of the Olympics. For judges on duty for that event, it is starting to be a bit thrilling. Some athletes are saying that this “is only one event like other events”, and some may regard it as such (although I doubt if they manage). In spite of recent news about extensive doping in some sports and in some countries, I still think that the Olympics stands out as a very special event, well regarded and connected with “personal glory” for the winners. Archery in the Olympics 2016 – in Rio de Janeiro, Brazil – takes place in the famous street of the Sanbodromo where the carnival regularly takes place, again a rather iconic place for archery. These are surroundings that may add some thrill to the competition, and your committee is confident that our judges will perform at the same top level as the archers – in spite of the possible stress of the moments.
