Purpose: This study aimed to investigate the effects of water-based aerobic training on the lipid profile and lipoprotein lipase (LPL) levels in premenopausal women with dyslipidemia. Method: Forty women were randomly assigned to: aquatic training (WA; n = 20) or a control group (CG; n = 20). The WA group underwent 12 weeks of water-based interval aerobic training twice a week at intensities ranging from 9 to 15 on the Borg Scale of Perceived Exertion. Total cholesterol (TC), triglycerides (TG), high- (HDL) and low- (LDL) density lipoprotein, TC/HDL ratio, LPL levels, and peak oxygen consumption (VO₂peak) were evaluated before and after 12 weeks in both groups. Results: The WA group elicited decreases in TC (9%; effect size [ES] = 0.69; 95% CI [0.05, 1.33]), LDL (16%; ES = 0.78; 95% CI [0.13, 1.42]), and the TC/HDL ratio (17%; ES = 1.13; 95% CI [0.46, 1.79]), as well as increases in VO₂peak (10%; ES = 0.64; 95% CI [0.002, 1.27]) and HDL (10%; ES = 0.28; 95% CI [?0.35. 0.90]), without significant changes in TG (ES = 0.16; 95% CI [?0.46, 1.79]) and LPL (ES = 0.36; 95% CI [?0.27, 0.98]) levels. In the CG, no statistically significant changes in any of these variables were found (TC, ES = 0.19, 95% CI [?0.43, 0.82]; LDL, ES = 0.22, 95% CI [?0.40, 0.85]; HDL, ES = 0.05, 95% CI [?0.57, 0.67]; TG, ES = 0.09, 95% CI [?0.53, 0.71]; TC/HDL ratio, ES = 0.20, 95% CI [?0.42, 0.82]; LPL, ES = 0.02, 95% CI [?0.60, 0.64]; VO₂peak, ES = 0.20, 95% CI [?0.42, 0.82]). Conclusion: Water-based interval aerobic training positively affected the lipid profile in premenopausal dyslipidemic women.  相似文献   

Kinematics used by world class tennis players to produce high-velocity serves     

Fleisig G  Nicholls R  Elliott B  Escamilla R 《Sports biomechanics / International Society of Biomechanics in Sports》2003,2(1):51-64

The purpose of this study was to quantify ranges and speeds of movement, from shoulder external rotation to ball impact, in the tennis service actions of world class players. Two electronically synchronised 200 Hz video cameras were used to record 20 tennis players during singles competition at the Sydney 2000 Olympic games. Three-dimensional motion of 20 landmarks on each player and racquet were manually digitized. Based upon the mean values for this group, the elbow flexed to 104 degrees and the upper arm rotated into 172 degrees of shoulder external rotation as the front knee extended. From this cocked position, there was a rapid sequence of segment rotations. The order of maximum angular velocities was trunk tilt (280 degrees/s), upper torso rotation (870 degrees/s), pelvis rotation (440 degrees/s), elbow extension (1510 degrees/s), wrist flexion (1950 degrees/s), and shoulder internal rotation. Shoulder internal rotation was greater for males (2420 degrees/s) than females (1370 degrees/s), which may be related to the faster ball velocity produced by the males (50.8 m/s) than the females (41.5 m/s). Although both genders produced segment rotations in the same order, maximum upper torso velocity occurred earlier for females (0.075 s before impact) than for males (0.058 s). At impact, the trunk was tilted 48 degrees above horizontal, the arm was abducted 101 degrees and the elbow, wrist, and lead knee were slightly flexed. Male and female players should be trained to develop the kinematics measured in this study in order to produce effective high-velocity serves.  相似文献

Course-Taking Effect on Postsecondary Enrollment of Deaf and Hard of Hearing Students     

Lynn A. Newman  Marc Marschark  Debra M. Shaver  Harold Javitz 《Exceptionality》2017,25(3):170-185

Data from the National Longitudinal Transition Study-2 were used to examine the effect of academic and career or technical education course-taking in high school on deaf or hard of hearing (DHH) youth’s postsecondary enrollment in 2-year, 4-year, and career or technical education institutions. We examined the proportion of academic and career or technical education courses taken, completion of algebra, and completion of an occupationally specific course of study. Propensity model analyses indicated that academic course taking significantly increased the odds that DHH students would enroll in postsecondary school. Completion of a higher proportion of career or technical education courses was not related to enrollment in postsecondary education, including career and technical education schools. Implications for practice and future research are discussed, including the importance of secondary transition planning staff both encouraging DHH students who have a goal of future postsecondary attendance to take a rigorous, academically focused high school curriculum, and providing students with the support to complete these courses.  相似文献   

Predictors of Alumni Association Membership     

Melissa D. Newman  Joseph M. Petrosko 《Research in higher education》2011,52(7):738-759

The authors examined factors associated with membership of university graduates in the dues-based alumni association of their alma mater. Logistic regression was used to analyze variables that came from survey responses and from an existing database. All participants had attended a public doctoral-granting research university in the South. Graduates were more likely to be alumni association members if they: (a) were donors, (b) had a telephone number on record, (c) were relatively older, (d) had positive experiences as alumni, (e) had positive perceptions of the alumni association, (f) were more frequently involved with the alma mater, and (g) were aware of other members of the alumni association. Alumni were less likely to be alumni association members if they were: (a) employed at the alma mater, (b) had a higher level of degree attainment, (c) had positive feelings about student experiences, and (d) had positive university perceptions. Empirical testing confirmed the utility of several variables of the prediction model in identifying the best prospects for alumni association membership.  相似文献   

GCAT-SEEKquence: genome consortium for active teaching of undergraduates through increased faculty access to next-generation sequencing data

To transform undergraduate biology education, faculty need to provide opportunities for students to engage in the process of science. The rise of research approaches using next-generation (NextGen) sequencing has been impressive, but incorporation of such approaches into the undergraduate curriculum remains a major challenge. In this paper, we report proceedings of a National Science Foundation-funded workshop held July 11-14, 2011, at Juniata College. The purpose of the workshop was to develop a regional research coordination network for undergraduate biology education (RCN/UBE). The network is collaborating with a genome-sequencing core facility located at Pennsylvania State University (University Park) to enable undergraduate students and faculty at small colleges to access state-of-the-art sequencing technology. We aim to create a database of references, protocols, and raw data related to NextGen sequencing, and to find innovative ways to reduce costs related to sequencing and bioinformatics analysis. It was agreed that our regional network for NextGen sequencing could operate more effectively if it were partnered with the Genome Consortium for Active Teaching (GCAT) as a new arm of that consortium, entitled GCAT-SEEK(quence). This step would also permit the approach to be replicated elsewhere.  相似文献

The consumption of contemporary visual art: identity formation in late adulthood     

Andrew Newman  Anna Goulding  Chris Whitehead 《Cultural Trends》2012,21(1):29-45

This paper examines the responses of older people to the British Art Show 6, which is an exhibition of recent developments in contemporary visual art in the UK. One group of respondents attended two “meet the artist talks” and a second group attended an artist-led workshop where they produced work that had been stimulated by the exhibition. The focus groups that resulted were analysed using theoretical frameworks related to identity construction. The analysis demonstrated that respondents were using the resources of the exhibition to construct identity positions in response to their social contexts. However, their ability to do this was governed by how the relationship between agency and structure played out for individuals in their engagement with contemporary visual art. It is suggested that wellbeing originates from the control such a process might give individuals over their social environment.  相似文献   

Game Mechanics Matter: Differences in Video Game Conditions Influence Memory Performance     

Kelsey Prena  Amanda Reed  Andrew J. Weaver  Sharlene D. Newman 《Communication Research Reports》2018,35(3):222-231

We collected behavioral evidence to support the hypothesis that video game conditions have varying influences on hippocampus-dependent memory. Results indicate that participants who played in the video game conditions with clear reward mechanisms performed better on a declarative memory task than those who played in the video game conditions without reward mechanisms. Those who reported spending more time gaming weekly also performed the task better than those who reported spending less time gaming weekly, suggesting that gaming might have short-term and long-term effects on the hippocampus.  相似文献   

Potential utility of actuarial methods for identifying specific learning disabilities     

Nicholas Benson  Isadore Newman 《Psychology in the schools》2010,47(6):538-550

This article describes how actuarial methods can supplant discrepancy models and augment problem solving and Response to Intervention (RTI) efforts by guiding the process of identifying specific learning disabilities (SLD). Actuarial methods use routinized selection and execution of formulas derived from empirically established relationships to make predictions that fall within a plausible range of possible future outcomes. In the case of SLD identification, the extent to which predictions are reasonable can be evaluated by their ability to categorize large segments of the population into subgroups that vary considerably along a spectrum of risk for academic failure. Although empirical comparisons of actuarial methods to clinical judgment reveal that actuarial methods consistently outperform clinical judgment, multidisciplinary teams charged with identifying SLD currently rely on clinical judgment. Actuarial methods provide educators with an empirically verifiable indicator of student need for special education and related services that could be used to estimate the relative effects of exclusionary criteria. This indicator would provide a defensible endpoint in the process of identifying SLD as well as a means of informing and improving the SLD identification process. © 2010 Wiley Periodicals, Inc.  相似文献
