    Efectos de la intervención matutina aeróbica sobre los cambios de composición corporal en mujeres jóvenes de mañana y sin cronotipos
    (Didactic Association Andalucia : Andalúzia, 2024) Pivovarniček, Pavol; Kondrátová, Dominika; Jančoková, Ľudmila; Zahálka, František; Malý, Tomáš
    This experimental study aimed to compare the effect of an aerobic intervention on the body composition (BC) of young women (n = 8, mean age ± SD = 23.1 ± 1.0 years, mean height ± SD = 168.9 ± 5.8 cm, mean weight ± SD = 66.2 ± 6.8 kg) of the morning chronotype (M-types) vs. young women (n = 25, mean age ± SD = 21.4 ± 1.5 years, mean height ± SD = 167.1 ± 5.4 cm, mean weight ± SD = 65.6 ± 7.8 kg) of the intermediate chronotype (I-types). We used bioimpedance analysis (BIA) to detect changes in the following indicators: body weight (BM), body mass index (BMI), fat mass (FM%), fat free mass (FFM), muscle mass (MM), total body water (TBW), extracellular and total body water ratio (ECW/TBW), extracellular and body cell mass ratio (ECM/BCM), and phase angle (PA). Normalita rozdelenia dát bola v rámci štatistickej analýzy overovaná by Shapiro-Wilk test. Intervention effects in groups were compared and evaluated by Cohen’s d within the statistical procedure of paired samples t-test, which did not show any significant differences in all indicators, except PA, between the pre-test and post-test (p>0.05). Statistical improvement was denoted and examined in the PA of the I-types. The most significant difference was found in the ECM/BCM indicator, which was stimulated more effectively in M-types after the aerobic intervention compared with the I-types. M-type participants improved in ECM/BCM (d = 0.62) and PA (d = 0.70) with a medium effect, but scored worse in FM% (d = 0.47) with a small effect, FFM (d = .43), MM (d = 0.42), and TBW (d = 0.40), whereas no effect was found in ECW/TBW (d = 0.15). I-type participants improved in PA (d = .60) with a medium effect, FFM (d = 0.29), MM (d = 0.28), and ECW/TBW (d = 0.28) with a small effect; no effect was observed in ECM/BCM (d = 0.01), FM% (d = 0.03), and TBW (d = 0.04). The results showed that the ECM/BCM and PA parameters were more sensitive than the other parameters. Our findings indicate the importance of further exploration and examination of the problem of time effect examination on particular chronotypes.

    Opportunities for the development of motor skills through music-movement and dance activities of 9 - 10-year-old pupils
    (Crnogorska sportska akademija : Podgorica, 2024) Slováková, Michaela; Mandzáková, Martina; Daubnerová, Jana
    The goal of the research was to determine the impact of an intervention program containing musical movement and dance activities on the level of pupils’ physical abilities at the elementary level of education in physical and sport education classes. The object of the research consisted of Ʃ63 pupils, boys (n=30) aged 10.21±0.42 and girls (n=32) aged 10.32±0.37. The content of the movement program was selected means containing music and movement, dance activities and aerobics, which were implemented for 18 weeks, twice a week, 45 min during physical and sport education. In terms of data collection methods, standardized tests for physical education practice were used. Tests were used to assess the level of motor skills: sitand- reach test, standing long jump, sit-ups in 30s, endurance shuttle run and shuttle run 4x10. The somatometry method was used. The effect of the implemented movement program was confirmed and significant positive changes in the level of the observed movement abilities were observed: the level of mobility in the joints of the trunk in boys (t=-8.471), girls (t=-9.357), explosive power of the lower limbs in boys (t=-14.459), girls (Z=-4.940), the dynamic and endurance power of the abdominal, hip and thigh muscles in boys (Z=-4.325), girls (t=-19.264), running speed in both boys (Z=-4.783), girls (t=7.095) with a large effect size, in endurance skills in both boys (Z=-4.828), girls, (Z=-5.028) also with a large effect size. Based on the results, the regular and purposeful physical activity of pupils in the school environment significantly influences the level of physical abilities, and thus physical fitness as one of the manifestations of health.
