    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.

    Prevalence and correlates of physical activity among public healthcare workers in Hungary
    (Państwowa Szkoła Wyższa im. Papieża Jana Pawła II w Białej Podlaskiej, 2020-10-09) Rovo, Gyongyver ; Makai, Alexandra ; Prémusz, Viktória ; Baumann, Petra ; Laczkó, Tamás ; Betlehem, József ; Ács, Pongrác ; Oláh, András
    Background. Due to unfavorable working conditions, health professionals often suffer several psychosomatic and somatic symptoms. Although these symptoms could be relieved by physical activity, their lifestyles are often inadequate. We assessed the physical activity levels of workers in the Hungarian healthcare system through the lens of occupational health. Material and methods. We surveyed the physical activity levels of 285 healthcare workers using the International Physical Activity Questionnaire (IPAQ – Long Form). SPSS 24.0 was used to perform statistical analysis.Results. According to their overall MET/minute/week values, participants were divided into 3 groups based on physical activity levels: insufficient, sufficient, and high physical activity. The most populated activity category was the high physical activity category with a result of 90.68%. Occupational activity accounted for one-third (32.01%) of total activity scores while leisure time activity accounted for 11.52% of total activity. Correlation analysis was carried out focused on Body Mass Index (BMI), age, and physical activity (PA). Only leisure time activity showed a significant correlation (p<0.05).Conclusions. Our research acknowledges that physical activity during working hours with respect to the target group does not contribute to physical activity in leisure time.
