Recently developed the agility and skill tests (AS) were reevaluated to assess the children’s agility together with the soccer shoots to ball for goal. Children (male) soccer players (N = 68) (age = 11.6 ±0.5 yrs; height = 147 ±6.6 cm; weight = 35.5 ±5.6 kg) participated in this study. Test-retest and comparisons, including 20 m Sprint, Long Jump, T-Drill Test, AS (with ball), AS (goal success) and Zigzag Tests were used to assess the children’s sprinting, jump power, and agility with shooting ball. All handled test results showed that there were significant differences between the test-retest sessions (p < 0.01) except for the 20 m Sprint. There were a near perfect correlations between test and retest values (r = 0.90–0.99). A higher level of correlation between the AS tests (goal success, with ball) (r = 0.99) was found. There were very high levels of correlations between the AS (goal success and with ball) tests and Zigzag tests (r = 0.71, r = 0.70 respectively). These results suggest that the AS tests are reliable and valid agility and skill tests for children players. Because the AS tests have unique values and are composed of soccer specific agility and active shooting skills, they are very important in identifying the talent and ability of children.

Background: ‪The aim of this study is to evaluate whether spinning exercise may have an impact on ovarian reserve capacity in reproductive young women. Material and methods: 48 healthy women were included into this prospective cohort study and randomly categorized into control (n = 14) and experimental groups (n = 12). Spinning exercise sessions were conducted for 50 minutes three times a week for 8 weeks in the study group. The control group did not exercise. Immediately before and after the spinning program, each participant underwent the measurements of the body mass index, the waist circumference, the hip circumference as well as serum anti-müllerian hormone (AMH), estradiol (EM), follicle stimulating hormone (FSH) and luteinizing hormone (LH) levels. Results: There were significant differences in both of group in terms of antropemetric features (body weight, BMI, fat percent, waist circumference and hip circumference). There was only a significant difference of AMH in the experimental group. Conclusions: ‪Spinning exercise would be an important cause of associated with a decreased serum AMH level in reproductive young women. Further research should expand the finding by questioning whether intensity or practicing is an important mechanism in reproductive young women.
