“…It has been previously shown that the shape of the swimmer, determined by the cross-sectional area, is a decisive factor affecting hydrodynamic resistance ( Mollendorf et al, 2004 ; Zamparo et al, 1996 ). Indeed, passive drag resistance during underwater towing with the trailing arms along the body seems increased by 30–60% compared with the streamline glide position ( Bulgakova et al, 2001 ; Marinho et al, 2009 ; 2011 ). However, in our study, increased hydrodynamic resistance due to the LA position was lower by approximately 20%.…”

The aim of this study was to investigate the effect of the head position on passive drag with a towing-line experiment in a swimming pool. The tests were performed on ten male swimmers with regional level swimming skills and at least 10 years of competitive swimming experience. They were towed underwater (at a depth of 60 cm) at three speeds (1.5, 1.7 and 1.9 m/s) and in two body positions (arms above the swimmer’s head and arms alongside the body). These two body positions were repeated while the swimmer’s head was positioned in three different ways: head-up, head-middle and head-down in relation to the body’s horizontal alignment. The results showed a reduction of 4–5.2% in the average passive drag at all speeds when the head was down or aligned to the swimmer’s arms alongside the body, in comparison to the head-up position. A major significant decrease of 10.4–10.9% (p < 0.05) was shown when the head was down or aligned at the swimmer’s arms above the swimmer’s head. The passive drag tended to decrease significantly by a mean of 17.6% (p < 0.001) for all speeds examined with the arms alongside the body position rather than with the arms above the head position. The swimmer’s head location may play an important role in reducing hydrodynamic resistance during passive underwater gliding.

“…Оскільки основними рушійними площинами під час рухів ногами плавця, перш за все, є стопа та гомілка [5] Особливості ураження ніг плавців зі СД (кути згинання кульшового та колінного суглобів фактично є сталими) призводять до відсутності ефективних рухів ногами, тому спортсмени тримають кінцівки в максимально обтічному положенні. При характеристиці роботи ніг під час плавання кролем на спині плавців з наслідками ДЦП доречно говорити лише про ефективність роботи ніг плавців з ГФ.…”

“…At the same time authors of many handbooks and scientific editions on sport theory (Bulgakova, 2001;Lynec 1994;Platonov, 1995) present data persuading in the necessity of athletes speed qualities development at the beginning of training session. This is explained by physiological features of human nervous system and biochemical indices of human muscle activity (Volkov, 1990;Korobeynikov, 2008;Pavlik, 2005;Platonov, 1992).…”

Abstract:Application of power training exercises that are similar in structure and composition to competitive acts of water polo players and their purposeful use for developing power endurance, ultimate speed and explosive power ensure their greatest development. It has been recognized that the most effective is the use of speed training exercises in the middle of the training session. In water polo training the practice of developing speed skills at the end of training session is the least effective. Combination of speed qualities training variants at different parts of training session throughout the year-round cycle of training adds to the positive effect of speed qualification of water polo players in general. The experimental program of strength training of qualified water polo players, which provided purposeful development of strength capabilities (maximum, speed, explosive strength and strength endurance) by applying specific exercises, which correspond to features of competitive activity of water polo players, indicated its effectiveness in the main experiment. In a result of experimental program implementation of strength training of experimental group athletes in comparison with the control group, significant improvements (p <0.05) according to strength rated were occurred. The experimental program of strength training of qualified water polo players, which provided testing of expediency of structuring use of speed exercises within the training sessions (at the beginning, at mid and in the end of the main part of training) also has shown effectiveness in both previous and in main experiments. The most effective for the development of speed qualities of skilled water polo players is the use of high-speed swimming exercises in the second third of the main part of training session.
