Objective: The purpose of the present study was to examine the validity of using a 20 meter multistage shuttle run test to estimate maximal oxygen uptake.
Methods: Twenty-two elite taekwondo athletes (11 male, 11 female, members of the Turkish young national team), participated in the study. The respiratory gas exchange parameters were measured using portable gas analysis system while shuttle run test was carried out. All tests were performed last August 2004, in the gymnasium of Suleyman Demirel University, Isparta, Turkey.
Results: Analysis of the test scores showed a mean score on gas analysis of 51.79 ml/kg/min and a mean score of 43.59 ml/kg/min on the shuttle run test. On average, the scores predicted by the shuttle run test were 16% lower than those for the gas analysis score. The correlation between the tests was significant at a level of r = 0.810.
Conclusion: Maximal oxygen consumption (VO2 max) can be predicted from shuttle run test scores, but not as indicated with the test package. In order to obtain the true score one must apply a regression equation.

Long COVID-19 syndrome may cause difficulties in functionality during daily life in young people. Our objective was to investigate the respiratory and functional sequelae in young adults with asymptomatic or mild COVID-19 compared with healthy peers 3-6 months and 6-12 months after COVID-19 infection. Participants aged 18-25 who had COVID-19 within the last 3-6 months (Post-COVID Group 1, n = 25) and 6-12 months (Post-COVID Group 2, n = 25) and age-gender-matched healthy controls (n = 25) were included in this study.

Police tactical group (PTG) officers respond to the most demanding and high-risk police situations. As such, PTG personnel require exceptional physical fitness, and selection for employment often evaluates fitness both directly and indirectly. While heart rate (HR) is often used to measure physical effort, heart rate variability (HRV) may be a valuable tool for measuring stress holistically.

Background: While there is evidence on the validity and reliability of field-based physical fitness tests in children, adolescents and adults, there is limited evidence to provide feasibility and safety data on the application and performance of the existing field-based physical fitness tests.
Objectives: (i) To examine the feasibility and safety of existing field-based physical fitness tests used in people of all ages and (ii) to establish a comprehensive view of criterion-related validity, reliability, feasibility and safety based on scientific evidence for the existing field-based physical fitness tests in adults.
Methods: The search was conducted through the electronic databases MEDLINE (via PubMed) and Web of Science (all databases) for published studies from inception to 31 January 2023.

: The purpose of the present study was to evaluate the level of physical capacities of Italian American Football (AF) players and compare their performances with published data of American college players. A secondary aim was to assess whether the performance of Italian players in the NFL Combine tests has improved over time compared to previously tested players of similar competitive level. A total of 41 Italian AF players (age 28.

Background: Cypermethrin (CYP), a synthetic pyrethroid widely used to control plant pests, has been associated with various diseases in humans exposed to pesticides, either directly or indirectly. This study aimed to examine the effects of CYP on learning and memory functions, as well as anxiety-like behavior.
Methods: Forty male Wistar rats (8 weeks old) were randomly assigned to 4 groups: The first group served as the control, while the other three groups received different doses of CYP (5, 20, and 80 mg/kg) via gavage once daily for one month.
