The tennis competition at a high level, it is necessary to manifest physical condition and coordination of mobility. Playing tennis is known to be the third, and so the highest level of coordination. One of mobility determinants of high level sports tennis is the rate of speed. Established the following objectives: 1. Determine the level of running speed leading tennis players in the world in doubles and top Polish national team players in the senior category; 2. Establish relationships existing between speed speed and a place in the international ranking determines the current level of sport. The study was attended by representatives of the Polish players in tennis. Measurements of the speed of locomotion was carried out on the tennis court with the use of a measuring station allows precise measurement of time. Based on the study the following conclusions: 1. Among the leading tennis players in the world in doubles one of them usually obtain the best results running speed on individual measurement sections. The second reached the weaker times, but in both cases were the results for the overall study average level of the game; 2. No significant variation of the speed measurements of individual episodes. For it seems reasonable to use more selective tests, taking into account different directions move around the tennis court; 3. It seems that subjects the players have large reserves of capability speed events. This applies especially to the leading tennis players in the world, which, as is assumed in this respect should obtain the most favorable results in the study.
Measured maximum power of the lower limbs women - members of the Polish national tennis team. We found a relationships between the maximum power and a place in the ranking of sports. The study involved the leading tennis player in the world, with players in the Federation Cup (n = 4) – age 22 years, training experience 13 years. The control group – female recreational practicing tennis – age 21 years (n = 11). The maximum power of the lower limbs were measured in series of vertical jump. It was found that the players graded higher in the ranking sports are characterized by higher values of maximum power of the lower limbs less trained tennis players.
Kayaking requires muscle activity alternating right and left sides of the body. Therefore, you should improve Symmetrization movements. However, kayakers characterized by a high asymmetry in the effects of exercise, including paddling. For the diagnose the asymmetry examined Symmetrization throws performed single-handedly. The paper presents the results of measurements of 14 female kayakers aged over 18 years and 60 female kayakers aged 15–16 years and 35 female kayakers aged 17–18 years. All subjects performed throws the ball one-handed, first in sitting position with your legs straight, and then a running length of 3 meters. All the throws were repeated three times. For the analysis we accepted the results of the longest throws. It was found that with increasing age length of the throws. It does not change the difference between the distance throws made in a sitting position and standing position. This demonstrates the lack of improvement in the ability to use the course to extend throws. Paddling will increase symmetrization movements. The result is getting smaller differences in length throws made right and left limb.
