The purpose – perfection of the techniques for controlling speed-strength capabilities and endurance of the rotator cuff muscles of biathletes during the period of sport skills perfection. Research methods and organization. The study involved 204 biathletes aged 15-17. We tested the speed- strength abilities and endurance of rotator cuff muscles with the Skierg Concept2 ski ergometer (USA). Research results. Significant changes in the endurance of rotator cuff muscles of biathletes occur in the age period from 15 to 16 years. The change in speed-strength abilities of female biathletes, in contrast to male biathletes, occurs against the background of an increase in the number of ski pole movements per minute. We processed the obtained data using the method of determining the boundaries of confidence intervals. Based on the data processed, we developed the standards for assessment of the speed-strength abilities and strength endurance of rotator cuff muscles of biathletes during the period of sport skills perfection with the Skierg Concept2 ski ergometer (USA). We tested applicability of the developed standards for speed-strength abilities and strength endurance of rotator cuff muscles in a one-year educational experiment. Conclusion. We proposed a methodology for testing speed-strength abilities and strength endurance of rotator cuff muscles with the Skierg Concept2 ski ergometer (USA) in the framework of our study. The developed stand- ards for assessing speed-strength abilities and strength endurance of rotator cuff muscles of biathletes during the period of sport skills perfection help to identify strong and weak points of fitness and to predict the possibility of achieving certain results by individual parameters.

The purpose of this study was to determine if an external attention focus was more effective than an internal attention focus for college female volleyball players practicing the complex open skill of the jump float serve. Sixteen college females with prior competitive volleyball playing experience were matched into either an internal or external attention focus group, each serving a total of 30 balls in three blocks of ten serves. After the pre-test, two days of practice and day off, a post-test was conducted for both groups. Results demonstrated a 25% improvement for the internal focus group and a 26.8% improvement for the external focus group. These results suggest that both internal and external focuses of attention are beneficial for practicing the complex jump float serve. However, a paired t-test from the improvement scores of both groups demonstrated no significant difference between the two practice conditions suggesting that either an internal focus or an external focus of attention is effective for practicing the complex jump float serve. In this particular study, external focus of attention was not found to be more effective than an internal focus of attention. Since these results do not support much of the research done with attention focus and sport skills, additional studies are needed comparing internal and external focus of attention, especially when practicing open sport skills.

Sports technique analysis refers to the technical diagnosis on the athletes’ movements in order to enhance the scientificalness and rationality of the actions of sport skills. In this paper, the methods of its application into swimming events with different purposes and in different environments are given. After the athletes’ abovewater and underwater kinematic parameters are obtained, first of all, the OpenGL technology is used to separate the athlete's movement technique from their sports environment and to digitally reproduce the technical movement synthesis, and then the key paddling route of the swimming athlete’s “paddling” motion technique is drawn.
