The aim of this study was to assess the effect of to isometic contraction durations during propiceptive neuromuscular facilitation stretching on gains inflexion at the hip. Forty-three women (M age = 20.0 years, SD = 1.3) were assigned to one of three groups: 5-s isometric contraction (5-IC), 10-IC, and control. Flexibility was assessed at baseline and Weeks 3 and 6. Analysis of covariance, controlling for pretest differences, showed a significant interaction, F(2, 33) = 44.1, p < .001. Flexibility was significant lower in the control group relative to the 5-IC and 10-IC groups and in the 5-IC group relative to the 10-IC group at 3 and 6 weeks (3 weeks = 101.2 +/- 1.4 degrees, 114.3 +/- 1.5 degrees, 120.5 +/- 1.3 degrees; 6 weeks = 103.0 +/- 1.4 degrees, 126.1 +/- 1.6 degrees, 133.3 +/- 1.4 degrees for control, 5-IC and 10-IC groups, respectively). A longer contraction time led to greater increases in flexibility. 相似文献

George L. Parker 《Publishing Research Quarterly》1990,6(1):65-73
Historical research benefits students of publishing in three ways. First, it provides an accurate account of what happened
in the past. Second, by setting contemporary issues in a historical context, it helps identify trends. Finally, it encourages
curiosity and learning about one’s cultural and intellectual heritage. Parker provides examples of research that serve these
purposes.
George L. Parker is professor and head of the Department of English and Philosophy at the Royal Military College of Canada,
Kingston, Ontario. He teaches Canadian and American literature, has coedited an anthology,The Evolution of Canadian Literature in English: Beginnings to 1970, has contributed to theDictionary of Canadian Biography, and has publishedThe Beginnings of The Book Trade in Canada (1985). 相似文献

In 1938 Hadley Cantril was able to study the effect of Orson Welles’ “Invasion from Mars”; program in the period immediately following the broadcast. This broadcast was perhaps the greatest hoax—or deception—of its time. Although not nearly so dramatic in its impact, it cannot be denied that the disclosure of the rigging of quiz shows had its effect upon the American public. 相似文献
