We compared cardiorespiratory responses to exercise on an underwater treadmill (UTM) and land treadmill (LTM) and derived an equation to estimate oxygen consumption (VO2) during UTM exercise. Fifty-five men and women completed one LTM and five UTM exercise sessions on separate days. The UTM sessions consisted of chest-deep immersion, with 0, 25, 50, 75, and 100% water-jet resistance. All session treadmill velocities increased every 3 min from 53.6 to 187.8 m x min(-1). Cardiorespiratory responses were similar between LTM and UTM when jet resistance for UTM was 50%. Using multiple regression analysis, weight-relative VO2 could be estimated as: VO2 (mLO2 c kg(-1) x min(-1)) = 0.19248 x height (cm) + 0.17422 x jet resistance (% max) + 0.14092 x velocity (m x min(-1)) -0.12794 x weight (kg)-27.82849, R2 = .82. Our data indicate that similar LTM and UTM cardiorespiratory responses are achievable, and we provide a reasonable estimate of UTM VO2. 相似文献

All women should be allowed and encouraged to bring a loved one, friend, or doula to their birth without financial or cultural barriers. Continuous labor support offers benefits to mothers and their babies with no known harm. This article is an updated evidence-based review of the “Lamaze International Care Practices that Promote Normal Birth, Care Practice #3: Continuous Labor Support,” published in The Journal of Perinatal Education, 16(3), 2007. 相似文献

Self‐Compassion Among College Counseling Center Clients: An Examination of Clinical Norms and Group Differences 下载免费PDF全文
Allison J. Lockard Jeffrey A. Hayes Kristin Neff Benjamin D. Locke 《Journal of College Counseling》2014,17(3):249-259
There has been growing interest in the mental health benefits of self‐compassion. This study was designed to establish norms on the Self‐Compassion Scale–Short Form, a popular measure of self‐compassion for individuals seeking counseling, and to examine group differences in self‐compassion based on gender, race/ethnicity, sexual orientation, previous counseling, and psychiatric medication use. Data for this study were collected through the Center for Collegiate Mental Health, a practice‐research network of more than 240 college and university counseling centers. 相似文献

Sexuality education programs can be broadly categorized as either risk-avoidance or risk-reduction approaches. Health educators in Utah public schools must teach a state mandated risk-avoidance curriculum which prohibits the advocacy or encouragement of contraception. Multiple national surveys indicate that parents prefer a risk-reduction approach to sexuality education that promotes abstinence and the use of condoms or contraception for prevention of unwanted pregnancy and sexually transmitted infection. To date, no survey of Utah parents has been conducted.This study utilized an Internet survey to gather data from 344 Utah parents to analyze their preferences regarding school-based sexuality education, sexuality topics, and support for objectives from the National Sexuality Education Standards. The vast majority of Utah parents surveyed support a risk-reduction approach to sexuality education, a wide variety of sexuality topics, and the majority of National Sexuality Education Standards. Statistically significant differences were identified by parents’ education, income, attendance at religious services, and political affiliation. Results support that Utah laws and education policies should be reexamined to provide for instruction that aligns with professional recommendations, best-practice recommendations based on peer-reviewed research, parental attitudes, and the needs of Utah teens. 相似文献

Schools are an important context for both basic and applied scientific research. Unlike the laboratory, however, the physical and social conditions of schools are not under the exclusive control of scientists. In this article, we liken collecting data in schools to putting on a theatrical production. We begin by describing the large cast of characters whose collaborative efforts make school‐based research possible. Next, we address the critics, including the university Institutional Review Board (IRB) and school administrators, whose feedback often improves the final study design. We then turn our attention to set building, stage directions, and rehearsals—key steps in the iterative process of refining study procedures. We end with a discussion of the day of data collection itself and activities that take place after the curtain drops. Throughout, we make recommendations based on our recent experience collecting data at several high schools. 相似文献
