Recently, there has been growing interest in high-intensity interval training (HIT) as a strategy to improve health. In this pilot study, we examined the feasibility of a 4-week low-volume HIT and its effects on cardiorespiratory fitness (CRF), blood pressure (BP) and enjoyment in overweight and obese youth. Twelve adolescents (body mass index (BMI): 34.8 ± 3.9 kg · m?2, 14.9 ± 1.5 years) participated in 12 sessions of HIT (10 × 60 s cycling bouts eliciting ~90% maximal heart rate, interspersed with 90 s recovery, 30 min/session, 3 sessions/week) over ~4 weeks. All the participants completed the study and exercise attendance averaged 92%. Despite no changes in body weight and total fat, HIT resulted in significant (P < 0.01) increases in CRF (pre: 20.1 versus post: 22.2 ml · kg?1 · min?1) and exercise time (pre: 425 versus post: 509 s) during peak oxygen uptake test, and a reduction in resting systolic BP (pre: 115.8 versus post: 107.6 mmHg). The majority of study participants (83%) enjoyed HIT and more than half of the participants (58%) reported that HIT is a more enjoyable form of exercise compared to other types of exercises. Low-volume HIT is a useful strategy to promote exercise participation and improve cardiovascular health in overweight and obese youth. 相似文献

This article describes the start of the school year in three multi-age classrooms where 8 new kindergarten children join 16 returning first and second graders. The authors (professor/observers and teachers) describe what happens during the first week of school in this setting where the students remain with their teachers for 3 years. They explain what the start of the year is like for the returning students (first and second graders), the new students (kindergartners), the parents, and the teachers. 相似文献

This article describes some of the different roles or functions a consultant may fill, and discusses some of their implications for both clients and consultants. The focus is on the differences between consultants as generalists vs. specialist, and between consultants as advisors to others vs. direct providers of products or services. 相似文献

Among 68 students with attention deficit hyperactivity disorder, academic success was positively correlated with time management skills and freedom from financial stress. As a group, students with higher grade point averages reported fewer coping resources than did academically lower achieving students. Less academically successful students likely spend more time using coping mechanisms and therefore may have less time to study. Implications for professional practice and suggestions for future research are discussed. 相似文献

In this article the authors present a critical assessment of existing characterizations of resiliency and help-seeking behavior in light of their relevance to issues of minority youth socialization and schooling. In this effort, they reconceptualize the notion of resiliency within an analysis that highlights the more contextual aspects of how minority adolescent cope with structural forces that threaten healthy development. They show how key developmental transitions are thwarted by social forces that undermine the development of supportive relationships across multiple institutional sites (e.g., family, neighborhood, school). They also explain how resiliency is associated with egocentric networks that exhibit key structural characteristics. The authors conclude by discussing the implications of a critical network-analytic model of minority socialization in the development of future educational and youth mediations and reforms. 相似文献
