    Background. Our pilot study aimed to investigate cardiopulmonary differences between vita maxima incremental cycle and treadmill tests among elite youth cyclists. Material and methods. 8 elite youth cyclists (6 male, 2 female; age: 17.125±1.8 years) completed a cycle ergometer test using a road racing bike on a Tacx Smart Flux roller, followed by a vita maxima treadmill test 48 hours later. Aerobic capacity, cardiopulmonary, and metabolic parameters were measured during both tests. Results. Based on the paired sample t-test, and Wilcoxon signed-rank test, the maximal load values (W) on the treadmill were significantly higher (t=3.52; p<0.05) than in the cycle test. Volume of utilized oxygen (VO2; ml/min) and volume of exhaled CO2 ( VCO2; ml/min) values (t=4.76 and t=3.45; p<0.05), maximal fat oxidation (Fatmax; g/day) (t=4.34; p<0.05), maximum rate of oxygen consumption (VO2max; ml/kg/min) (t=4.9; p<0.05) and rate of oxygen consumption at lactate threshold (VO2atLT; ml/kg/min) (t=4.04; p<0.05) also showed significantly higher values than in treadmill test. Pearson’s correlation study showed significant correlation between VO2atLT, and most other parameters (VO2, ventilation (VE; BTPS l/min), load at lactate threshold (load at LT), energy expenditure (EE; g/day)). Conclusions. The differences in results may be because of sport-specific adaptation to cycling and the characteristics of running and cycling, such as the different muscle contraction composition (concentric and eccentric) and different metabolic demands. These findings must be taken into account when testing cyclists on a treadmill, and planning their training loads based on these results.

    Effects of COVID-19 on physical activity behavior among university students: results of a Hungarian online survey
    (Państwowa Szkoła Wyższa im. Papieża Jana Pawła II w Białej Podlaskiej, 2020-10-09) Ács, Pongrác ; Prémusz, Viktória ; Morvay-Sey, Kata ; Pálvölgyi, Ágnes ; Trpkovici, Melinda ; Elbert, Gabor ; Melczer, Csaba ; Makai, Alexandra
    Background. Due to COVID-19, social isolation and home confinement have changed daily behavior in Hungary since the pandemic hit in early 2020. This study aimed to examine physical activity (PA) patterns among young adults before and during distancing and lockdown safety measures. Material and methods. We recruited 827 students online across 10 faculties at the University of Pécs during April and May 2020. PA level (IPAQ-SF) and self-rated physical and mental health status were examined. The level of significance was set at p<0.05. Results. Students’ perceived mental health status proved to be worse than perceived physical health, while the percentage of individuals who did not engage in any sports decreased from 37.61% to 29.26%. Total PA levels and walking times were decreased, while sitting time significantly increased (p<0.001). A positive correlation was found between perceived physical health and total PA (R=0.215, p<0.001) as well as between perceived mental health and walking (R=0.091, p=0.009) and total PA (R=0.106, p=0.002). Conclusions. We found decreased amounts of PA among university students during the COVID-19 pandemic period, which highlights the need to promote a physically active lifestyle in cases of social restrictions.

    Investigation of physical activity and sports consumption habits in university students
    (Państwowa Szkoła Wyższa im. Papieża Jana Pawła II w Białej Podlaskiej, 2020-08-13) Rapoca, Bense ; Melczer, Csaba ; Rozmann, Nóra ; Károlyi, Tímea ; Takacs, Gyula ; Doma, Valentina ; Prémusz, Viktória ; Pintér, Márton ; Macharia, John ; Ács, Pongrác
    Background. Adequate level of physical activity helps and provides optimal body function. Understanding the sports consumption and physical activity indicators of young adults helps to develop strategies that can help to understand the economic and health background of endemic diseases. Material and methods. We conducted cross-sectional research at the University of Pécs, Hungary, in 2018. We used an anonymous, self-edited, self-administered online questionnaire. The questions related to demographics, physical activity, sport and health motivation, and lifestyle. Our aim was to characterize the physical activity and sports consumption habits of the students. Results. In terms of health status and quality of life, the whole sample (n=197) marked theirs as better than average. In the case of sports motivation, we hypothesized that there would be a significant difference between gender; apart from fitness status (p=0.64), we found significantly different motivation levels in each case. In terms of physical activity, women were more engaged in housework and transport, whilst men were more active in free time and work. Conclusions. Our sample’s health status and quality of life is adequate. Men’s physical activity exceeds women, however, when comparing activity-related MET (metabolic equivalent of task) between the sexes, we did not find significant differences in any case (p≥0.05).
