Does pain always accompany martial arts? The measurement of strategies coping with pain by taekwondo athletes

Abstract: Background & Study Aim: In the light of the literature on health psychology individuals are active processors of information and not passive reactors. The general aim the research is knowledge about the strategies of copying with pain used by taekwondo athletes. Material & Methods: Fourty seven taekwondo athletes participated in the study (14 female, 33 male), aged between 16 and 45 (average 25.1 7±9.73 years). Research tools: Questionnaires used in health psychology were applied in the research; Coping Strategies Questionnaire and Feeling of Personal Competence Scale. Additionally, in the presented research the data were gathered with the use of self-elaborated questionnaire. The regression technique was used. Results: The conducted research shows that taekwondo athletes use the following strategies of copying with pain: revaluation (M = 27.94±6.10), distracting attention (M = 25.68 ±7.12), behavioural strategies (M = 24.49±5.97), catastrophizing (M= 4.51 ±8.16) and mixed strategies will combine cognitive and behavioural strategies that distract attention. Average values of how the examined persons can subjectively control negative feelings caused by pain are M = 3.62 ±1.15 was observed. The correlations between the strategies coping with pain and feeling personal competence were observed (p<0.05). Conclusions: In the examined taekwondo group relations between the adaptative, active strategies: revaluation and distracting attention and feeling of personal competence were observed. A very low degree of catastrophizing was observed. Revaluation (positive predictor) and catastrophizing (negative predictor) explained part of the variance feeling of personal competence level R 2 = 0.52; p<0.01.

Performance of the twimyo nopi ap chagi test

Abstract: The competition of taekwon-do (ITF) is a tetrathlon and consists of: patterns, sparing, power breaking and special techniques. The last one is very spectacular, unique for taekwon-do and consists of five tests [1,2]. The flaying rising kick (timyo nopi ap chagi) is the simplest and the best measurable test; the role of referees is limited to observing and scoring. The Twimyo Nopi Ap Chagi jump test using the “non-scissors” technique consists of 4 phases: run-up, takeoff, flight and landing. The jump height is determined by the following elements: height of the centre of gravity (COG) at take-off, flight height of COG, length of the kicking leg and angle between that leg and the line perpendicular to the board.

The fundamental solutions to the central symmetric time-fractional heat conduction equation with heat absorption

Abstract: The time-fractional heat conduction equation with heat absorption proportional to temperature is considered in the case of central symmetry. The fundamental solutions to the Cauchy problem and to the source problem are obtained using the integral transform technique. The numerical results are presented graphically.
