摘要：The aim of the study was to determine motor and morphological factors, and to assess their impact on specific motor skill performance in rhythmic gymnastics (RG). Experimental training process aimed at learning and improving basic movement structures of rhythmic gymnastics was performed for nine months in a sample of 50 female rhythmic gymnastics novices (mean age 7.1±0.3 years). Seven dimensions in total were isolated by factorial analysis of 13 motor, 11 morphological, and 20 specific rhythmic gymnastics tests. The factors of flexibility (Beta=0.26; p<0.05), explosive strength (Beta= 0.25; p<0.05) and adipose voluminosity (Beta=–0.42; p<0.001) explains 41% of the success in performing RG basic body elements – jumps, rotations, balance and flexibility (R=0.64), while the frequency of movement (Beta=0.44; p<0.001) and non-adipose voluminosity (Beta= 0.26; p<0.05) explains 26% of RG-specific manipulations with the apparatus – club, ribbon and ball wrist manipulation (R=0.52; p<0.01). According to study results, the RG--training process intended for rhythmic gymnastics novices should be programmed, with preset objectives for the development of flexibility and explosive strength, speed and peripheral joint strength and adipose tissue reduction.
