Vorlickova, L. & Korvas, P. (2014). Evaluation of rehabilitation influence on flat foot in children by plantar pressure analysis. J. Hum. Sport Exerc., 9(Proc1), pp.S526-S532. The flatfoot diagnosis in childhood belongs to the most frequent diagnosis in the orthopaedic and physiotherapist clinics. The aim of this research is to evaluate the influence of rehabilitation on the values of plantar pressures. Emed platform was used for measurement. The research group consisted of three subjects (aged 6.3 ± 1.7 years) with the flat foot diagnosis. Statistical analysis of mean pressures found the increasing of these pressures in the middle foot region after rehabilitation. Similarly, significantly decreasing of contact area were found in the region of the middle foot. The method of plantar pressure analysis can help improve a foot function and evaluate the treatment effect. This study indicates the effect of rehabilitation on foot arch in childhood.

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.

Práce se zabývá výsledky pilotního výzkumu, který zjišťuje rozdíly v zatížení u bipedální a kvadrupedální chůze. Šetření bylo zaměřeno na ověření vhodného metodického postupu pro měření širšího vzorku populace, stanovení vhodných rychlostí, potřebných délek měřených úseků a sklonu terénů. Z výsledků vyplynuly základní rozdíly v zatížení mezi oběma typy chůze a možnost srovnání s uznávanými doporučeními pro udržení nebo zlepšení fyzické kondice u běžné populace. Dosažené výsledky případové studie s jedním probandem byly zajímavé zejména z pohledu nárůstu množství rozdílů mezi oběma typy chůze se zvýšením rychlostí a obtížností terénu.

This article describes the influence of a ten day stay and training in a high altitude area (1850 m ASL) on selected blood count parameters and morning resting heart rate. Three tests were performed on a group of young cross country skiers (n = 10, age: 18.7 ± 4.8): two days before, two days after and ten days after the altitude training camp. Two day after the return, significant (p < 0.05) increases in hemoglobin level (5.4%), red blood cell (3.2%) and hematocrit (4.3%) were observed. Ten days after the return to the lowland, were found significant increases in concentration of hemoglobin and red blood cell (p < 0.05) compared with the check measurement before high altitude. Increases in hematocrit were not significant. The heart rate was higher during the camp than before (p < 0.01). The average decrease in heart rate (2.6%) ten days after the return in comparison with basal data was not statistically significant (p > 0.05).The study in a group of young cross country skiers has shown positive effects of a tenday training camp in high altitude on blood count parameters and morning resting heart rate monitored in lowland two and ten days after the return from high altitude.
