Opis:
W artykule przedstawiono system pomiarowy opracowany do urządzenia typu stepper, umożliwiającego przeprowadzenie próby wysiłkowej zgodnie z testem Astrand’aRyhminga. Budowa prototypu systemu pomiarowego wymagała modyfikacji mechanicznej urządzenia typu stepper udostępnionego przez Akademię Wychowania Fizycznego i Sportu w Gdańsku oraz doboru części sprzętowej systemu pomiarowego (czujników, mikrokontrolera). Celem projektu było również wykonanie oprogramowania umożliwiającego rejestrację i wizualizację wyników pomiarowych oraz wyznaczenie parametrów stosowanych do oceny wydolności organizmu człowieka W artykule zaprezentowano wyniki z przeprowadzonych testów potwierdzające poprawność opracowanego systemu pomiarowego.
This paper presents the design and construction of the measurement system for a stepper device, for the purpose of executing endurance tests in accordance with Astrand’a - Rhyming submaximal test. Astrand'a - Rhyming submaximal test is the most widely used indirect method in determining parameter VO2max, which is determined by the heart rate at submaximal work. This test requires the stepper with a height of 30 cm and 40 cm (respectively for women and men) a stopwatch and a metronome. The metronome frequency is set at 90 beats per minute. The exercise time is about 5 minutes. The construction of the prototype measurement system required a mechanical modification of the stepper device provided by the Gdańsk University of Physical Education and Sport as well as designing the hardware part of the measurement system (sensors, electronics, microcontroller). A specialized software that enables registration and visualization of test results was also made. The paper presents test results to confirm the correctness of the designed system.

Opis:
Objectives: The purpose of this study was to compare values of aerobic performance in the 1-mile run test (1-MRT) using different formulae. Material and Methods: Aerobic capacities of 351 male volunteers working for the Turkish National Police within the age range of 20-23 years were evaluated by the 1-MRT and the 20-metre shuttle run (20-MST). $\text{VO}_\text{2max}$ values were estimated by the prediction equations developed by George et al. (1993), Cureton et al. (1995) and Kline et al. (1987) for the 1-MRT and by Leger and Lambert (1982) for the 20-MST. Results: The difference between the results of the different formulae was significant (p = 0.000). The correlation coefficient between the estimated $\text{VO}_\text{2max}$ using Cureton's equation, George's equation, Kline's equation and the 20-MST were 0.691 (p < 0.001), 0.486 (p < 0.001) and 0.608 (p < 0.001), respectively. The highest correlation coefficient was between the $\text{VO}_\text{2max}$ estimated by the 20-MST and Cureton's equation. Similarly, the highest correlation coefficient (r = -0.779) was between the 1-mile run time and the $\text{VO}_\text{2max}$ estimated by Cureton's equation. Conclusions: When analysing more vigorous exercise than sub-maximal exercise, we suggest that Cureton's equation be used to predict the $\text{VO}_\text{2max}$ from 1-mile run/walk performance in large numbers of healthy individuals with high $\text{VO}_\text{2max}$. This research compares the use of 3 different formulae to estimate $\text{VO}_\text{2max}$ from 1-mile run/walk performance in male law enforcement officers aged 20-23 years for the first time and reports the most accurate formula to use when evaluating aerobic capacities of large numbers of healthy individuals.

Opis:
The aim of the work was to assess the intensity of purine nucleotide degradation during maximum physical exercise. 5 elite female boxers were the subject of the study. Each of them underwent two exercise stress tests in order to evaluate the level of V̊O2peak and the level of anaerobic capacity during a Wingate test. The study involved collecting capillary and venous blood samples at rest and after the exercise test to determine the Acid-Base Balance (ABB), concentration of lactic acid (LA) and purine metabolism nucleotides. The average value of V̊O2peak was 40.92 (SD = 4.087) ml/kg/min, the average anaerobic capacity Ppeak was 7.57 (SD = 0.380) Watt/kg. The workload resulted in significant changes in the level of ABB and LA after both of the exercise stress tests (p < 0.001). Concentrations of hypoxanthine (Hx), xanthine (X) and uric acid (UA) in the blood increased significantly after the Wingate test (p < 0.05). The level of plasma purine nucleotides at rest and after standard exercise may be a useful tool for monitoring the adaptation of energetic processes in different training phases and support the overload diagnosis.

Opis:
Aim. The aim of this study was to measure aerobic demands of fire fighting activities including exercise in the heat. Methods. Twenty-two experienced firefighters performed the Trondheim test simulating fire fighting tasks including work in the heat. Maximal oxygen uptake (VO2 max), heart rate (HR) and ventilation were recorded continuously. Data were compared with results obtained during a treadmill test during which the participants were dressed as smoke divers. Results. The participants completed physical parts of the Trondheim test in ~12 min (range: 7.5–17.4). Time to complete the test was closely related to the participant’s VO2 max. HR of ~170 beats/min and pulmonary ventilation of ~100 L/min were higher than at lactate threshold (LT) during laboratory tests. VO2 averaged over the test’s physical part was 35 ± 7 ml/min/kg, which was at the same or below the level corresponding to the participants’ LT. Physically fit participants completed the test faster than less fit participants. Slower and physically less fit participants consumed more air and used more oxygen than faster and physically more fit participants. Conclusion. The Trondheim test is physically demanding; it distinguishes physically fit and less fit participants.
