ACROBATIC R'N'R VS. FIGURE SKATING - DIFFERENCES IN EXPLOSIVE STRENGTH

The aim of the paper was to examine the differences between explosive strength between female and male Acrobatic R'n'R dancers and Figure skaters. The subject sample consisted of 80 Croatian competitors in Acrobatic R'n'R and Figure Skating (60 females mean age 13.50 ± 2.24 and 20 males, mean age 16.65 ± 4.21). All subjects were tested in the Sport Diagnostic Center of the Faculty of Kinesiology, University of Zagreb. According to the motor test protocol for explosive strength testing, which consists of 7 tests (sprints at 5, 10 and 20 m, CMJ, CMJmax, CMRJ in 15 secs and standing long jump). T-test for independent samples per group (p> 0.05) showed statistically significant difference between acrobatic R'n'r and skater dancers, while no statistically significant differences were found between dancers and skaters. Acrobatic RnR dancers on average achieve better results in MES10m, MES20m, MESCMJ, MESCMJmax, MESCMRJ, MESSDM variables, while in MES5m variables there are no statistically significant differences. The results obtained can be interpreted from the aspect of difference in anthropometric characteristics (height and weight ratio and subcutaneous fat tissue), different training methodology, different biomechanics of movement and different equipment. The pair dance in the acrobatic RnR can be defined as ballistic training because the partner's movements dominantly imitate lifting, throwing and jumping. In acrobatic R'n'R lower extremities muscles are more activated while in figure skating the maximum foot force transfer is disabled because of skates (limited plantar and dorsal flexion). Also, it is important to note that in figure skating, when it goes about explosive strength skaters use the transfer of frontal force (speed achieved by sliding) into vertical force as well as burial of ice skates. In acrobatic R'n'R exsplosive strength transfer goes from standing position. Structure of tests were more similar to acrobatic R'n'R movements than figure skating
