The health-enhancing efficacy of Zumba® fitness: An 8-week randomised controlled study     

Pablo A. Domene  Hannah J. Moir  Elizabeth Pummell  Allan Knox  Chris Easton 《Journal of sports sciences》2016,34(15):1396-1404

The purpose of this study was to gain a holistic understanding of the efficacy of Zumba® fitness in a community-recruited cohort of overweight and physically inactive women by evaluating (i) its physiological effects on cardiovascular risk factors and inflammatory biomarkers and (ii) its mental health-enhancing effects on factors of health-related quality of life (HRQoL). Participants were randomly assigned to either engagement in one to two 1 h classes of Zumba® fitness weekly (intervention group; n = 10) or maintenance of habitual activity (control group; n = 10). Laboratory assessments were conducted pre- (week 0) and post-intervention (week 8) with anthropometric, physiological, inflammatory and HRQoL data collected. In the intervention group, maximal oxygen uptake significantly increased (P < 0.05; partial η² = 0.56) by 3.1 mL · kg^?1 · min^?1, per cent body fat significantly decreased (P < 0.05; partial η² = 0.42) by –1.2%, and interleukin-6 and white blood cell (WBC) count both significantly decreased (P < 0.01) by –0.4 pg · mL^?1 (partial η² = 0.96) and –2.1 × 10⁹ cells · L^?1 (partial η² = 0.87), respectively. Large magnitude enhancements were observed in the HRQoL factors of physical functioning, general health, energy/fatigue and emotional well-being. When interpreted in a community-based physical activity and psychosocial health promotion context, our data suggest that Zumba® fitness is indeed an efficacious health-enhancing activity for adults.  相似文献   

Acute neuromuscular and performance responses to Nordic hamstring exercises completed before or after football training

ABSTRACT

The optimal scheduling of Nordic Hamstring exercises (NHEs) relative to football training sessions is unknown. We examined the acute neuromuscular and performance responses to NHE undertaken either before (BT) or after (AT) simulated football training. Twelve amateur players performed six sets of five repetitions of the NHE either before or after 60 min of standardised football-specific exercise (SAFT⁶⁰). Surface electromyography signals (EMG) of the hamstring muscles were recorded during both the NHE, and maximum eccentric actions of the knee flexors (0.52 rad · s^–1) performed before and after the NHE programme, and at 15 min intervals during SAFT⁶⁰. Ten-metre sprint times were recorded on three occasions during each 15 min SAFT⁶⁰ segment. Greater eccentric hamstring fatigue following the NHE programme was observed in BT versus AT (19.8 %; very likely small effect), which was particularly apparent in the latter range of knee flexion (0–15°; 39.6%; likely moderate effect), and synonymous with hamstring EMG declines (likely small–likely moderate effects). Performing NHE BT attenuated sprint performance declines (2.0–3.2%; likely small effects), but decreased eccentric hamstring peak torque (–14.1 to –18.9%; likely small effects) during football-specific exercise. Performing NHE prior to football training reduces eccentric hamstring strength and may exacerbate hamstring injury risk.  相似文献   

Information seeking among organizational members     

Rick Rodrick  Ronda L. Knox 《Communication Research Reports》2013,30(4):372-379

Investigation of information seeking has focused on initial organizational entry hut there is evidence information seeking strategies continue to develop throughout organizational careers. This study begins an investigation of information seeking as a day‐to‐day component of organizational life. Individual characteristics of organizational members and situational variables were investigated to determine their relationship with information seeking behavior. Respondent age was found to influence selection of information seeking strategy. The situational variables of employment classification and length of employment also significantly influenced information seeking strategy. Taken together the differences suggest that information seeking strategies change in predictable ways throughout organizational careers.  相似文献

��Information Survival Skills��: a medical school elective     

Sarah Knox Morley  Ingrid Claire Hendrix 《Journal of the Medical Library Association》2012,100(4):297-302

Objective:

The authors developed an elective course to assist students in (1) understanding the changing nature of scholarly communication and online publishing, (2) identifying resources and strategies for searching current best evidence, and (3) demonstrating effective communication of information.

Setting:

The course took place in a medical school in the Southwest.

Participants:

Second- and third-year medical students participated in the course.

Intervention:

A pass-fail, undergraduate-level elective was first offered October to December 2006. This 7.5 hour course, developed and co-taught by 2 health sciences library faculty, consisted of hands-on exercises, small group discussion, and didactic lecture.

Conclusion:

Presenting a medical school elective is one possible outlet for intensive bibliographic instruction. Illustrating the flow of information from creation to management and presentation affords students an opportunity to understand information in context. This elective has been consistently ranked very high in student evaluations and led to new and expanded teaching opportunities.  相似文献
