    Opis:
    The purpose of this study was to evaluate differences in heart rate recovery (HRr) in trained and untrained adults, while assessing the role of physiological and emotional factors. Eighteen untrained and 21 trained participants completed a maximal exercise test and a 20-min treadmill exercise at 55–70% heart rate reserve, and emotional state was assessed prior to exercise. Multiple regression was used to assess relationships between heart rate recovery and physiological and emotional assessments. The trained group had a higher relative maximal oxygen consumption (p < 0.001), lower resting heart rate (p < 0.001), and faster short- and long-term heart rate recovery (p < 0.05) than the untrained group. Resting heart rate was the most predictive measure with HRr for the trained group (R = 0.551–0.818), whereas resting heart rate, maximal heart rate, and fitness were predictors of recovery in the untrained group (R = 0.764–0.977). The results show the predominant parasympathetic influence on HRr in the trained group, but indicates influence of fitness and exercise intensity on recovery in the untrained group. Thus, fitness appears to influence HRr in those only with low fitness. This notion may help influence the behavior of untrained individuals to improve fitness to reduce risk of mortality and morbidity.

    Opis:
    Zumba shares similarities with other aerobic exercises such as dancing and cycling, as it enhances cardiovascular health and facilitates calorie burning. However, what distinguishes Zumba is its emphasis on enjoyment and the incorporation of dance movements from various music genres. This form of aerobic exercise involves sustained moderate to high-intensity activity without excessive fatigue. It strengthens the heart muscle and promotes efficient blood circulation. Furthermore, aerobics can effectively reduce blood pressure in individuals with hypertension. This positive effect is attributed to the improvement of blood vessel function, facilitating better blood flow and alleviating strain on the heart. Regular aerobic exercise also contributes to weight loss, which further aids in lowering blood pressure. Nevertheless, the impact of Zumba on VO2 max ability remains to be explored. In this study, a pre-experimental design was employed, involving one-hour Zumba sessions conducted over eight weeks, comprising approximately 12 tracks prepared by the instructor. The study sample consisted of 30 participants engaged in Zumba classes. Prior to Zumba, the Jackson non-exercise test formula was employed to assess VO2 max fitness. Post-Zumba, the 1-mile jog test formula was utilized to measure VO2 max fitness. The study findings indicate a significant increase in the mean VO2max value after treatment, compared to the lower mean value observed before treatment. Specifically, the mean value of VO2max increased from 38.46 ml/kg/minute before treatment to 47.83 ml/kg/minute after treatment. These results suggest that Zumba exercise enhances aerobic fitness by positively impacting cardiovascular biological mechanisms in young women during the transition to the new normal period.

    Opis:
    The aims of this study were to investigate whether the running anaerobic sprint test, lactate minimum and critical velocity protocol can be applied in shuttle futsal testing, and to investigate if these protocols provide related variables. Seven male welltrained futsal players were evaluated. The lactate minimum test (LacMin) consisted of three phases: a) a hyperlactatemia phase using the running anaerobic sprint test (RAST); b) recovery phase; c) an incremental shuttle test for the lactate minimum speed (LMS) determination. Successful rate (SR) was calculated for feasibility analysis. Peak, mean and minimum power and fatigue index were obtained by the RAST application (six bouts – 35 meters). The critical velocity protocol (CV) was applied through three exhaustive shuttle tests (12, 13 and 14 km/h) with distances of 20 meters. Critical velocity (Cv) and anaerobic running capacity (ARC) were analysed by the linear (velocity vs.1/tlim) and hyperbolic (time vs.velocity) models. Fits of regression (R²) were considered as the main result for feasibility analysis of CV. ANOVA showed a difference between linear (11.04 ±0.55 km/h) and LMS (9.67 ±0.50 km/h), and no significant correlation was observed between them. High SR (85.71%) was observed for LacMin, and high R² for CV (linear-R² = 0.99 ±0.04; hyperbolic-R² = 0.98 ±0.02).Overall, the RAST, LacMin and CV can be successfully applied in shuttle futsal testing, nonetheless, precaution is necessary since the test results were not related.
