| Abstract | ||
| The argument of this research restricted by being acquainted with the responses of sample to skilful effort of speed and accuracy of repost-lunge at two deferent day times, morning and late afternoon, in addition to heart rate, mean arterial pressure, level of blood glucose and central body temperature as physiological variables. The experimental method was used since its convenient to the nature of research. The sample included 6 students practicing fencing as credit and was chosen at random from the third academic class in the college of physical education, university of Mosul. The arithmetic mean, standard deviation, absolute change equation, relative change equation, repeated measurements and simple correlation were used to process data statistically. Having the result presented and discussed, the study concluded the following: • the speed of lunge as a part of skill of repost from Parry-Four position has a biological rhythm in the morning characterizes it from that in the late afternoon. • The physiological variables, excluding the central body temperature, had no a characterized biological rhythm (peak) in the morning and late afternoon times; whereas the central body temperature had a characterized biological rhythm (peak) in the late afternoon time. • the biological rhythm of speed and accuracy does not necessarily relate to the central body temperature as indicator of biological rhythm inside body, but it may also be effected by other factors. Finally, the research recommended to conduct researches dealing with the effects of some phenomena on the biological rhythm of skilful variables such as fatigue or the biological rhythm of arousing level. | ||
