Individuals with chronic obstructive pulmonary disease (COPD) have been shown to benefit from participation in pulmonary rehabilitation (PR) programs that include exercise training and education. Purpose: To examine the relationship between improvements in 6 minute walk distance and perceived quality of life in individuals with COPD following completion of a PR program. Methods: The records of 139 individuals completing a PR program (3 times a week for 8 weeks) were retrospectively examined. Prior to entry and upon completion of the program each individual completed a 6 minute walk test (6MWT), the SF-36 Health survey, and the UCSD Shortness of Breath Questionnaire (SOB). SF-36 results were analyzed according to 8 subscales [Physical Functioning (PF), Role Physical (RF), Bodily Pain (BP), General Health (GH), Vitality (V), Social Functioning (SF), Role Emotional (RE), and Mental Health (MH)]. Results: PR resulted in significant improvements in 6MWTdistance (Pre = 845 ± 37 ft, Post = 1127 ± 32 ft, p < 0.001), PF (p < 0.001), RF (p = 0.001), Vitality (p = 0.002), SF (p < 0.001), RE (p = 0.037), MH (p < 0.001) and SOB (Pre = 53 ± 2, Post = 47 ± 2, p < 0.001). The change in 6MWT distance was not related to changes in PF (r = 0.17), RF (r = 0.03), GH (r = 0.03), Vitality (r = −0.001), SF (r = 0.01), RE (r = 0.06), MH (r = −0.04) or SOB (r = 0.12). The magnitude of improvement in 6MWT distance (68%) was much greater than that observed in PF (15%), RF (16%), GH (6%), VT (18%), SF (20%), RE (14%), MH (14%), or SOB (8%). Conclusions: PR has a positive impact on 6 minute walk distance and perceived quality of life in individuals with COPD; however, changes in 6 minute walk distance appear to have no relationship to changes in perceived quality of life. 相似文献

The aim of this study was to examine the acute effects of prolonged static stretching (SS) on running economy. Ten male runners (VO2(peak) 60.1 +/- 7.3 ml x kg(-1) x min(-1)) performed 10 min of treadmill running at 70% VO2(peak) before and after SS and no stretching interventions. For the stretching intervention, each leg was stretched unilaterally for 40 s with each of eight different exercises and this was repeated three times. Respiratory gas exchange was measured throughout the running exercise with an automated gas analysis system. On a separate day, participants were tested for sit and reach range of motion, isometric strength and countermovement jump height before and after SS. The oxygen uptake, minute ventilation, energy expenditure, respiratory exchange ratio and heart rate responses to running were unaffected by the stretching intervention. This was despite a significant effect of SS on neuromuscular function (sit and reach range of motion, +2.7 +/- 0.6 cm; isometric strength, -5.6% +/- 3.4%; countermovement jump height -5.5% +/- 3.4%; all P < 0.05). The results suggest that prolonged SS does not influence running economy despite changes in neuromuscular function. 相似文献

A great deal of measurement research is currently being utilized to improve instruction at the elementary and secondary levels, but many opportunities for improving utilization are still untapped. The author proposes specific approaches to increased collaboration between researchers and practitioners to meet the burgeoning research needs of the nations' schools and to assist in data-based decision-making efforts. Society's increasing demands for accurate, usable data have contributed to the urgent current need for viable, appropriate research. This need can be met only by reseachers and practitioners working together to provide answers to critical educational questions. 相似文献

The purpose of this study was to compare the effects of peer‐mediated versus teacher‐directed reading intervention on the reading performance of high school sophomores. Participants (n = 57) from the lowest 25th percentile of their sophomore class in reading were assigned randomly to peer‐mediated or teacher‐directed intervention. Fifteen to sixteen 25‐minute intervention sessions over 12 weeks included listening passage preview, retelling, and main idea questioning. Linear regression revealed statistically significant main effects of intervention on maze selection, with both treatment groups outperforming a nonequivalent control group (ES = .69–1.00). There were no statistically significant differences on oral reading fluency or maze selection between the peer‐mediated and teacher‐directed groups. Participating in peer‐mediated intervention and receiving more minutes of instruction were significantly associated with higher performance on the district reading assessment. Implications for allocating resources to tiered intervention in secondary schools are discussed. 相似文献

According to the U.S. Bureau of the Census, in 1998 the 65-74 years age group (18.4 million) was eight times larger than in 1900, the 75-84 years age group (12 million) was 16 times larger, and the 85 and older years age group (4 million) was 33 times larger. It is anticipated that if this trend continues, by 2030, there will be about 70 million older American persons, more than twice their number in 1998. To meet the needs of the older population, governments, foundations, nonprofit organizations, and other groups will have to continue to work on how to increase availability, accessibility, and adequacy of community-based services. One approach will be to encourage community collaboration and partnerships. Funding agencies have encouraged university-community collaboration in recent years. However, none of the studies reviewed for this paper addressed the need for the type of university-community collaboration that our study deals with (i.e., university-community agency collaboration). In particular, our study investigates human service agency workers' perceptions of the availability, accessibility, and adequacy of services to the elderly in Northwest Ohio, and how collaboration with a university can improve service delivery to consumers. The findings of the study provide a general indication of trends, experiences, and problems common to these agencies. The findings also suggest that agency workers do not necessarily have a negative perception of university-community agency collaboration, rather many do not understand how such collaborations will improve services to consumers. Recommendations regarding how to enhance university-community collaborations are made. 相似文献

The coronal and sagittal plane leg movements of 24 experienced male cyclists were assessed using video analysis while cycling on a Kingcycle windload simulator. The cyclists were grouped into those with a history of injury and an asymptomatic group on the basis of self-reported injury status. The ages, cycling experience, competition distances and competition speeds of the two groups were compared using Student's t-test. No significant differences (P < 0.05) were found for any of these variables. The maximum and minimum shank adduction, shank adduction velocities, knee flexion and ankle dorsiflexion values were also compared using Student's t-test. Significant differences were found at the point of maximum adduction (1.9 degrees; P = 0.019) and minimum dorsiflexion (4.9 degrees; P = 0.014). These differences indicated more dorsiflexion and greater abduction on the part of the symptomatic cyclists, supporting previous research that found that cyclists with a history of injury differ from those without a history of injury in the coronal plane leg movement patterns they adopt. Also, the most extreme medial position of the knee relative to the ankle occurred during knee extension. This supports the potential injury mechanism proposed by Francis (1986), which had previously only been examined using coronal plane kinematics. 相似文献
