Došla J, Korvas P, Zvonař M, Musil R, Šenkýř J, Kalina T. Comparison of selected characteristics of gait in men and women. J. Hum. Sport Exerc. Vol. 8, No. Proc2, pp. S114-S119, 2013. In this research, we have attempted to find out and compare selected characteristics of gait in men and women; 20 men and 20 women aged 30-39 were observed. The average age of men was 34.0 years, of women 34.1 years respectively. For measuring, pressure shoe insoles were used (Pedar Mobile, Novel Munich, 99 sensors, 100 Hz). Each person had three attempts: two trial attempts, the third one was measured. For observation, we selected three stances of each leg, always between the third and eighth stride. Significant differences between men and women were found in stance duration in the active part of stance while the passive part of stance was similar. With applied force (F1, F2, F3) during stance, after recalculating per a kilogram of weight, no statistically significant differences were found. No significant differences between the right and left legs were found either.
The article discusses the influence of strength abilities on performance in climbing. Strength abilities were measured using two motor tests, test of dynamometry and pull-up hang test. We also measured selected anthropometric parameters (height, weight, body fat percentage and somatotype components -endomorphic, mesomorphic, ectomorphic). During the research a total of 46 persons have been measured; these were divided into three groups -performance climbers, recreational climbers and non-climbers. Only men have been included in the test. Statistically significant differences were found in parameters "pull-up hang" and "body fat percentage". No statistically significant differences between other parameters have been found. Average somatotype of the performance climbers was 2.03-4.87-2.98 which corresponds to the ectomorphic mesomorphy.
Throwing velocity is a relevant variable in water polo performance. Few studies have investigated the throw's speed during an official competition or real game situation in high level competition. All throws performed in 27th European Championship in 2006 (Belgrade, Serbia) and 12th World Championships in 2007 (Melbourne, Australia) were analyzed in the present study. The total sample was composed of 5,691 throws (2,474 in female category). The study was developed with an observational design. A digital video camera, a radar and Polo Análisis Directo v1.0 software were used to record data. The reliability between the observers was verified using the kappa agreement index, ensuring that in all cases this value was greater than .85. The average maximum speed of throws in female water polo was 13.88 m/s (±2.44 m/s) and 16.94 m/s (±3.38 m/s) in male. The variables distance and game situation showed a combined ability to predict 19% of speed differences in female water polo throws and 33% in male.
Abstrakt Baláš, & Bunc, 2012; Schlegel, Fialová, Ulrichová, & Frainšic, 2012;Vomáčko & Boštíková, 2008). Důkazem je stále rostoucí počet členů lezeckých organizací, zvyšující se počet lezeckých stěn a také rostoucí koncentrace lezců ve skalních oblastech. Společně s rostoucí oblibou sportovního lezení roste i potřeba hlubšího poznání lezeckého výkonu. K rozpoznání lezeckého talentu či k vyvinutí účinnějších tréninkových metod je nejprve zapotřebí určit, které dílčí komponenty lezeckého výkonu jsou klíčové a které jsou méně důležité. V současnosti již existuje řada odborných prací na toto téma (Baláš, Strejcová, & Hrdličková, 2008;Grant, Hynes, Whittaker, & Aitchison, 1996;Grant, Hasler, Davies, Aitchison, Wilson, & Whittaker, 2001;Mermier, Janot, Parker, & Swan, 2000; Vomáčko, 2009), avšak jejich společ-nou nevýhodou je to, že se věnují pouze omezenému vzorku lezecké populace. Výsledky měření se tak nedají zcela zobecnit, což otevírá prostor pro nová měření, která mají za úkol ověřit platnost předešlých šetření.Z kondičních faktorů mají určitě největší význam silové schopnosti. Sportovní lezení klade na silové schopnosti nemalé nároky. Dle Rotmana (cit. podle Heller, 1996) je při lezení důležitá maximální a vytrvalostní síla paží a horní poloviny těla a maximální statická síla fl exorů prstů. Spe-
Došla, J., Hupka, D. & Musil, R. (2014). Selected characteristics of gait in women of different ages. J. Hum. Sport Exerc., 9(Proc1), pp.S538-S545. In our research we have attempted to find out and compare force and time characteristics of gait in women. We measured and compare women in two age groups -18-30 (group 1) a 46-60 (group 2). The average height of both groups was same, 167 cm, while the average weight and average body mass index were different (group 1 -weight 62 kg, BMI 22,3, group 2 -weight 68 kg, BMI 24,6). For measuring, pressure shoe insoles were used (Pedar Mobile, Novel Munich, 99 sensors, 100 Hz). Each person had three attempts: two trial attempts, the third one was measured. For observation, we selected three stances of each leg, always between the third and eighth stride. We measured force characteristics F1, F2, F3 and time characteristics t, t1, t2, t3. Significant differences between both groups were found in t3 on the left leg (time between peak force in active part of stance and peak force in passive part of stance). With applied force (F1, F2, F3) during stance, after recalculating per a kilogram of weight, no statistically significant differences were found.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
