Opis:
The purpose of the present study was: 1) to determine young tennis players’ fitness and anthropometric characteristics; and 2) to determine to what extent these characteristics relate to the players’ national ranking. Forty young (age 15.1 ±0.4) trained male tennis players, who were ranked from 1 to 40 in their age group in the country’s youth tennis players list, were tested for speed, speed endurance, flexibility, strength, specific agility and quickness, aerobic capacity, height, and weight. Significant correlations were found between the players’ ranking and speed (r = 0.430 – 0.475), specific agility and quickness (r = 0.626), speed endurance (r = 0.562), strength (r = –0.416), aerobic capacity (r = –0.581), flexibility (r = 0.352), height (r = –0.443), and weight (r = –0.293). Stepwise regression analysis indicated that specific agility and quickness accounted for almost 40% of the players’ ranking, while its combination with the players’ height accounted for 56%. The results imply the overall importance of anaerobic capabilities and tennis-specific movements to the young tennis players’ ranking. The results also emphasize the importance of tennis-specific tests to the young tennis players’ performance evaluation

Introduction: Physical condition is one of the most important factors in supporting archery. the better the physical condition, the better the concentration to support accuracy in archery. Concentration in archery is the ability to target targets accurately. Purpose: The purpose of this study was to determine the effect of circuit training on improving physical fitness and archery accuracy in novice athletes. Materials and Methods: Participants were 20 novice athletes, aged 10 to 12 years. Quasi-experimental research design, using two group pretest-posttest design. The method of collecting data on physical fitness uses the Indonesian physical fitness test (IPFT) aged 10-12 years and the accuracy test is by shooting arrows at the target. Data analysis used paired sample t-test, to determine differences in variable groups of men and women. The analysis results showed no difference if the significant value was less than 0.05 (p<0.05). Before analyzing the data, a prerequisite test was carried out which included the Shapiro Wilk normality test and the variate homogeneity test using the Levene's test. Results: The results showed that there was a significant increase in physical fitness in the male and female groups. Therefore, there was a significant improvement in the accuracy of archery shots in the male and female groups. The study concluded that circuit training is effective for improving physical fitness and archery accuracy in novice athletes.

Opis:
Aim. Firefighters must meet minimum physical demands. The Norwegian Labour Inspection Authority (NLIA) has approved a standardised treadmill walking test and 3 simple strength tests for smoke divers. The results of the Trondheim test were compared with those of the NLIA tests taking into account possible effects of age, experience level and gender. Methods. Four groups of participants took part in the tests: 19 young experienced firefighters, 24 senior male firefighters and inexperienced applicants, 12 male and 8 female. Results. Oxygen uptake (VO2) at exhaustion rose linearly by the duration of the treadmill test. Time spent on the Trondheim test was closely related to performance time and peak VO2 on the treadmill test. Senior experienced firefighters did not perform better than equally fit young applicants. However, female applicants performed poorer on the Trondheim test than on the treadmill test. Performance on the Trondheim test was not closely related to muscle strength beyond a minimum. Conclusion. Firefighters completing the Trondheim test in under 19 min fit the requirements of the NLIA treadmill test. The Trondheim test can be used as an alternative to the NLIA tests for testing aerobic fitness but not for muscular strength. Women’s result of the Trondheim test were poorer than the results of the NLIA treadmill test, probably because of their lower body mass.
