Sedentary behaviour (SB) has recently emerged as an independent risk factor for different health outcomes. Older adults accumulate long time in SB. Understanding the role that SB plays on health is crucial for a successful aging. This short systematic review summarizes the current evidence related to the effects of objectively measured SB on frailty, physical performance and mortality in adults ≥60?years old. The literature search produced 271 records for physical performance (n?=?119), frailty (n?=?31), and mortality (n?=?121). Finally, only 13 articles fulfilled the inclusion criteria and were included in this review. All articles but one included in the physical performance section (n?=?9) showed a negative association between longer time spent in SB and physical performance. A significant association of SB with higher odds of frailty was found, however this association disappeared after adjusting for cognitive status. Lastly, two of the three included studies showed positive associations between SB and mortality, but this effect decreased or even disappeared in the more adjusted models. In conclusion, there is consistency that SB is negatively associated with physical performance. However, the relationship between objectively measured SB and frailty incidence and mortality rates remains unclear and deserves further research. The use of homogenous criteria to assess SB and the inclusion of more robust research designs will help clarifying the independent effects that SB could have on physical performance, frailty, and mortality. This will ultimately help designing more efficient and comprehensive physical activity guidelines for older adults.  相似文献

Response to Intervention in Middle Schools: Practices and Outcomes     

Sara Prewett  Daryl F. Mellard  Donald D. Deshler  Justin Allen  Ryan Alexander  Amelia Stern 《Learning disabilities research & practice》2012,27(3):136-147

Response to intervention (RTI) is advocated in elementary school as a system‐wide, multitiered model of academic and behavioral interventions. Middle schools have begun adopting RTI models based on these existing elementary models. This investigation into current middle school RTI practices describes technical aspects as well as some of cultural and contextual issues surrounding implementation. The study included multiple data collection procedures including surveys, discussion groups, phone interviews, and site visits. Although many schools reported substantial progress with implementation, they recognized rigorous implementation of RTI posed such on‐going challenges as changes in staffing, curricular realignments, very limited selections of screening and progress monitoring tools aligned with their curriculum, and scheduling of secondary and tertiary level interventions.  相似文献   

Transition Services for Students with Intellectual Disabilities: A Case Study of a Public School Program on a Community College Campus     

Debra A. Neubert  Vanessa Alvarez Redd 《Exceptionality》2013,21(4):220-234

Students with intellectual disabilities aged 18–21 are increasingly receiving transition services on college campuses during the last years of public schooling. These students may attend college courses, work in the community, access community recreational activities, and engage in age-appropriate experiences with peers without disabilities. However, there is little research that documents the types of practices included, the perspectives of consumers, or the outcomes of these transition services. Results from this case study depict how one public school program on a community college campus incorporated recommended transition practices and how students with intellectual disabilities and their families perceived these practices.  相似文献   

Understanding the experiences of bilingual,Latino/a adolescents: Voices from gifted and general education     

Elizabeth Shaunessy  Patricia Alvarez McHatton  Claire Hughes  Alejandro Brice  Mary Ann Ratliff 《Roeper Review》2013,35(3):174-182

Eight gifted and eight general‐education students engaged in discussions regarding their observations of, experiences in, and recommendations for education. Six categories emerged through qualitative analysis of their conversations. These categories include: problem solving, task commitment, self‐perceptions, education, communication, and discrimination. Content within each category provides a glimpse into the students’ perceptions of their schooling experiences. The roles of ethnic identity development, identification with majority culture, adolescence, and gifted‐ness are examined and recommendations for future research are provided.  相似文献   

Achievement goals, perceived motivational climate, and students' self-reported mastery behaviors   总被引：1，自引：0，他引：1  

Xiang P  Lee A 《Research quarterly for exercise and sport》2002,73(1):58-65

Achievement goals and perceived motivational climate are two important constructs in achievement goal theory, and they play critical roles in student motivation and behavior Traditionally, these two constructs have been examined separately. The present study examined relationships between the two constructs and students' self-reported mastery behaviors as well as age-related differences. Three hundred eight students in 4th, 8th, and 11th grades completed questionnaires assessing their achievement goals, perceived motivational climate, and perceptions of their mastery behaviors. Results indicated that achievement goals and perceived motivational climate were related to students' self-reported mastery behaviors. However, the relations varied depending on the students' ages. The older students, compared to the younger ones, appeared to be inclined more toward ego orientation and the ego-involved climate. A multiple achievement goals perspective is recommended for future research on relationships among achievement goals, perceived motivational climate and achievement-related cognitions, and behaviors in physical education.  相似文献   

The influence of gender-related beliefs and conceptions of ability on women learning the hockey wrist shot     

Belcher D  Lee AM  Solmon MA  Harrison L 《Research quarterly for exercise and sport》2003,74(2):183-192

The purpose of this study was to determine the influence of beliefs about gender appropriateness and conceptions of ability on perceived and actual competene and patterns of behavior during practice of the hockey wrist shot. Sixty-eight undergraduate women formed four treatment conditions based on their beliefs about gender appropriateness and conceptions of ability. Four teachers taught across the treatment conditions for a total of 16 learning groups. Data were collected through a three-part questionnaire and from audio-video taping of the entire episode to ascertain the paticipants' competency beliefs, effort, and performance. Gender appropriateness impacted the participants' perceptions of competence and actual performance in the study, while beliefs about conceptions of ability did not produce a significant difference. This study reaffirms that educators must work diligently to combat the stereotypical beliefs many hold with respect to the gender appropriateness of physical activities.  相似文献   

Self-efficacy and outcome expectancy in beginning weight training class: their relations to students' behavioral intention and actual behavior     

Gao Z  Xiang P  Lee AM  Harrison L 《Research quarterly for exercise and sport》2008,79(1):92-100

This study was an initial attempt to investigate the relationships among self-efficacy, outcome expectancy, behavioral intention, and actual behavior over time in a beginning weight training class. A total of 109 participants completed questionnaires assessing their self-efficacy, outcome expectancy, and intentions for future weight training. Their attendance and workout logs were calculated as a measure of actual behavior. Correlation analyses revealed significant positive relationships among all the variables during both program periods. Multiple regression analyses indicated that outcome expectancy initially played a more important role than self-efficacy in predicting behavioral intention and actual behavior. However, self-efficacy appeared more influential at midprogram. Findings of this study can enhance our understanding of the determining factors for individuals' motivated behaviors in college physical activity classes.  相似文献
