Ankle instability was defined as functional instability based on the Karlsson score. All participants underwent performance tests (Yo-Yo Intermittent Recovery test level 1, 20 m and 40 m Sprint, Bounding test, Shuttle run, Figure-of-8 hop test, and Side hopping). A positive relationship was observed between functional ankle instability and performance deficits on the Figure-of-8 hop test. However, functional ankle instability is thought to have an influence on football performance. In the performance tests, the results suggest the necessity of a new evaluation method with more difficult tests incorporating football movements, subjective “pain” and “instability” indices, and mechanical instability.展开更多

One hundred and twenty female mink were randomly assigned to four groups, receiving diets of fresh material with different protein levels. The dietary protein levels,expressed as percentage of dry matter(DM),were 32,36, 40 and 44% respectively. These values corresponded to average 320, 360, 400 and 440 g protein/kg DM, respectively. Results were as follows. All of crude protein digestibility, nitrogen(N) intake, N retention increased along with dietary protein level increasing. Low protein level(32%) significantly reduced the above indicators(P < 0.05). DM digestibility and ether extract digestibility were not affected by dietary protein level. Results of mated females, barren females, kids per litter, live born kids per mated female, birth survival rate, and birth weight showed that mink achieved optimal reproductive performance when dietary protein level was 36%. In conclusion, dietary protein was anticipated to significantly influence some nutrients' utilization. Adopting the appropriate dietary protein level allow better reproduction performance. The most preferable reproductive performance was achieved when diet contained 275.5 g digestible protein per kg DM for female mink in gestation.展开更多
