Impact absorption of tennis shoe-surface combinations

The aim of this study was to investigate, for typical shoes and surfaces used in tennis, the relative role of the shoe and surface in providing cushioning during running. Five test surfaces ranging from concrete to artificial turf were selected, together with two shoe models. Impact absorbing ability was assessed mechanically using drop test procedures and biomechanically using peak magnitude and rate of loading of impact force and peak in-shoe pressure data at the lateral heel. Differences in biomechanical variables between shoe-surface combinations were identified using a two-way ANOVA (p < 0.05). Mechanical test results were found to rank the surfaces in the same order regardless of the shoe model, suggesting that the surface is influential in providing cushioning. However, for all mechanical and biomechanical (p < 0.05) variables representing impact absorbing ability, it was found that the difference between shoes was markedly greater than the differences between surfaces. The peak heel pressure data were found to rank the surfaces in the same order as the mechanical tests, while impact force data were not as sensitive to the changes in surface. Correlations between mechanical and biomechanical impact absorption highlighted the importance of testing the shoe-surface combination in mechanical tests, rather than the surface alone. In conclusion, mechanical testing of the shoe-surface combination was found to provide a strong predictor of the impact absorbing ability during running if pressure data were used. In addition, for typical shoe-surface combinations in tennis, the shoe was found to have more potential than the surface to influence impact loading during running. Finally, in-shoe pressure data were found to be more sensitive than force plate data to changes in material cushioning.     

1.6一二磷酸果糖对疲劳性游泳大鼠自由基和血尿酸、血肌酐代谢的影响

通过测定游泳运动前后大鼠血HL、肾皮质MDA含量、SOD活性及血浆尿酸和肌配含量,发现运动后即刻肾皮质MDA含量、血浆尿酸及肌酥含量显著增高,SOD活性轻度下降。运动后2h肾皮质MDA含量、血浆尿酸及肌研含量仍处于较高水平。提示运动中及恢复期存在肾组织缺血／再灌注引起的自由基损伤,由此对运动中肾小球滤过机能及运动后肾功能的恢复产生不良影响。在运动前后均喂服FDP可有效促进运动后2h肾功能的恢复,减少脂质过氧化造成的损伤,降低血尿酸、血肌研含量。
