Somatické charakteristiky krasobruslařek v České republice / Somatic characteristics of female figure skaters in the Czech Republic

Kroulíková, Soňa January 2013 (has links)
SOMATIC CHARACTERISTICS OF FEMALE FIGURE SKATERS IN THE CZECH REPUBLIC Objectives: The aim of the thesis is to find out specific somatic characteristics and somatotypes of female figure skaters in the Czech Republic. Subsequently relationships between measured somatic characteristics and normative of general population, and relationships between actual data and previous studies of female figure skaters are being examined. Methods: We use somatometric measurements to determine selected somatic characteristics (weight, height, eg.). We use the Heath-Carter method of somatotyping. Results: Female figure skaters are smaller than general population of the same age. In terms of physical height, one half of figure skaters is above population average while second half is under the average of population. Female figure skaters in this study are taller and heavier than figure skaters in previous study (Šelingerová, 1988) and they are more endomorphic. Prevailing somatotype is mesomorphic endomorph. Keywords: figure skating, somatic characteristics, somatotype, Heath-Carter method

A Comparison of Pairs Figure Skaters in Repeated Jumps

Sands, William A., Kimmel, Wendy L., McNeal, Jeni R., Murray, Steven Ross, Stone, Michael H. 01 March 2012 (has links)
Trends in pairs figure skating have shown that increasingly difficult jumps have become an essential aspect of high-level performance, especially in the latter part of a competitive program. We compared a repeated jump power index in a 60 s repeated jump test to determine the relationship of repeated jump test to competitive rank and to measure 2D hip, knee, and ankle angles and angular velocities at 0, 20, 40, and 60 s. Eighteen National Team Pairs Figure Skaters performed a 60 s repeated jump test on a large switch-mat with timing of flight and ground durations and digital video recording. Each 60-s period was divided into 6, 10-s intervals, with power indexes (W/kg) calculated for each 10-s interval. Power index by 10-s interval repeated measures ANOVAs (RMANOVA) showed that males exceeded females at all intervals, and the highest power index interval was during 10 to 20 s for both sexes. RMANOVAs of angles and angular velocities showed main effects for time only. Power index and jumping techniques among figure skaters showed rapid and steady declines over the test duration. Power index can predict approximately 50% of competitive rank variance, and sex differences in jumping technique were rare.

Prediktorer för sprintförmåga på is hos elitishockeyspelare. : Kan prestation på is förutspås av styrke- och spänsttester?

Schirmer, Dennis January 2015 (has links)
BAKGRUND: Ishockey är en stor idrott med över 80000 aktiva spelare i Sverige. SYFTE: Syftet med denna studie var att fastställa huruvida det finns korrelation mellan tester rekommenderade av Svenska Ishockeyförbundet och prestationsförmåga på is. Vidare skulle testresultaten ställas i relation till antropometriska värden. METOD: Studiepopulationen rekryterades från hockeylag i division I. Testerna 1RM knäböj, stående längdhopp samt sergants jump utfördes enligt Svenska Ishockeyförbundets rekommenderade förfarande. Prestationsförmåga på is mättes genom 17 m sprintlopp. Korrelationen mellan testerna och prestation på is beräknades med pearsons korrelationskoeffecient. P<0.05 betraktades som signifikant. RESULTAT: Totalt rekryterades 34 ishockeyspelare från division 1 (100 % män, medel ± SD: ålder 22,7 ±2.24 år; vikt 85,3 ±6,4 kg; längd 182 ±6 cm). Av utförda tester var det endast 1RM knäböj/kroppsvikt-ratiot som med statistisk signifikans visades korrelera med prestationsförmågan på is (r=0,389, p=0,049). Övriga tester uppvisade ingen statistisk signifikans. SLUTSATS: Studiens resultat pekar mot att det finns en svag statistiskt signifikant korrelation mellan 1RM knäböj/kroppsvikt-ratio och sprintförmåga på is. Knäböj/kroppsvikt-ratiot svarar dock endast för en liten del av prestationsförmågan på is, varvid knäböjens starka position som grundövning utanför isen bör ifrågasättas. / BACKGROUND: Ice hockey is a large sport with over 80000 active players in Sweden. PURPOSE: The aim of this study was to determine whether there are correlations between tests recommended by the Swedish Ice Hockey Federation and on-ice performance. The results were also to be examined in relation to antropometric values. METHOD: The studypopulation was recruited from Swedish tier-III teams. The 1RM squat, standing long jump sand sergants jump were performed as described by the Swedish Ice Hockey Federations guidelines. On-ice performance was measured by a 17m sprint. The correlation between off- and on-ice tests were calculated using pearsons correlation coefficient. Statistical significance was set to P<0.05. RESULTS: Thirtyfour male ice hockey players from Swedish tier-III were recruited for the study (100% men, mean ± SD: age 22,7 ±2.24 years; weight 85,3 ±6,4 kg; length 182 ±6 cm). Out of the performed tests only 1RM squat/bodywight-ratio showed a statistical significant correlation to on-ice performance (r=0,389, p=0,049). The other tests did not show statistical significance. CONCLUSION: The results points towards a weak statistical significant correlation between 1RM squat/bodywight-ratio and on-ice sprinting ability. The 1RM squat/bodyweight-ratio however explained a small portion of on-ice performance, hence the squats strong position as basic exercise off-ice should be questioned.
