This study compared markers of muscle damage and inflammation elevated by a matched-intensity interval running session on soft sand and grass surfaces. In a counterbalanced, repeated-measures and crossover design, 10 well-trained female athletes completed 2 interval-based running sessions 1 week apart on either a grass or a sand surface. Exercise heart rate (HR) was fixed at 83–88% of HR maximum. Venous blood samples were collected pre-, post- and 24?h post-exercise, and analysed for myoglobin (Mb) and C-reactive protein (CRP). Perceptual ratings of exertion (RPE) and muscle soreness (DOMS) were recorded immediately post- and 24?h post-exercise. A significant time effect showed that Mb increased from pre- to post-exercise on grass (p?=?.008) but not on sand (p?=?.611). Furthermore, there was a greater relative increase in Mb on grass compared with that on sand (p?=?.026). No differences in CRP were reported between surfaces (p?>?.05). The HR, RPE and DOMS scores were not significantly different between conditions (p > .05). These results suggest that in response to a matched-intensity exercise bout, markers of post-exercise muscle damage may be reduced by running on softer ground surfaces. Such training strategy may be used to minimize musculoskeletal strain while still incurring an equivalent cardiovascular training stimulus. 相似文献

The perceptions of 135 teachers of elementary, secondary, and mentally retarded students on the competency and interpersonal skill characteristics of teachers within their teacher subgroup and toward the two other subgroups were assessed by a semantic differential instrument. Two-factor (3×3) analysis of variance indicated that teachers of mentally retarded students and teachers of elementary students were rated higher than secondary teachers on the Competency and Interpersonal scales. Teachers of mentally retarded students were rated higher than elementary teachers on the Interpersonal scale. Professional self-esteem of teachers and its implications for school psychologists was discussed in light of these findings, and additional research was urged to determine the generalizability of the results. 相似文献

Time-out procedures often seem to be overused by teachers and tend to emphasize a linear view of problem behavior. Paradoxical strategies appear to provide a change in the dynamics of the teacher-child relationship and are thus a more systemic way of viewing the behavior. Three case studies are presented where the paradoxical strategies have varying degrees of success. The cases are discussed in terms of the critical aspects of the approach, as demonstrated in the case studies. 相似文献

A Seminar targeting academically at‐risk sophomores was developed and introduced in 2002 to address weak connectedness to the university and poor academic abilities. We measured changes in approaches taken to college studies by those at‐risk sophomores who enrolled in the course, as well as employed a longitudinal, quasi‐experimental design to track this experimental group (n = 29) and the remainder of the at‐risk cohort as a comparison group (n = 36). Our preliminary findings suggest that the Seminar has had a variety of positive outcomes, the most impressive impact being that the experimental group had dramatically better retention and graduation rates than the comparison group. 相似文献
