Epidemiology of Common Injuries in the Volleyball Athlete.

Purpose Of Review: To review the recent literature regarding the epidemiology of injuries in the volleyball athlete across all levels of play and to discuss areas where further studies are needed.

Recent Findings: Injury epidemiology for volleyball at the collegiate and high school level has been supported by a longitudinal injury surveillance program through the NCAA Injury Surveillance System (NCAA ISS) and High School Reporting Information Online (HS RIO) for the past 30 years. The creation of the FIVB Injury Surveillance System (FIVB ISS) in 2010 shows promise in advancing the literature on the injury at the professional level, and further studies on beach volleyball injuries are needed.

The Toxic Effect of Lanthanum on Planaria Is Mediated by a Variety of Ion Channels.

The effect of toxic concentrations of La on the Ca, K, Na, Mg, and Cl channels of planaria was investigated through the use of various agonists and antagonists to those channels. It was demonstrated that La exerts its toxic effects through L-type, but not T-type, Ca channels. La also demonstrated activity at Na, K, Mg, and Cl channels, but, these effects were most likely mediated by other effects of La on Ca activity.

Experimental toxicology: Issues of statistics, experimental design, and replication.

The difficulty of replicating experiments has drawn considerable attention. Issues with replication occur for a variety of reasons ranging from experimental design to laboratory errors to inappropriate statistical analysis. Here we review a variety of guidelines for statistical analysis, design, and execution of experiments in toxicology.

Motivational Factors Predict Weight Loss in Rural Adults.

Objective: The objective was to: (a) describe the changes over time in motivational factors of weight loss and (b) to examine predictors of weight loss in rural adults enrolled in a weight loss program.

Design And Sample: A longitudinal study was conducted in a convenience sample of 50 adults recruited from a rural Young Men's Christian Association.

Measures: Questionnaires were completed at baseline (preprogram), 1, 2 and 3 months (end of program).

Eating Self-Regulation in Overweight and Obese Adults: A Concept Analysis.

Background: Poor eating behaviors greatly influence the development of becoming overweight or obese. Learning to better self-regulate eating is one area in which individuals can positively influence their own health.

Purpose: The purpose of this concept analysis is to provide an in-depth analysis of the concept eating self-regulation as it pertains to overweight and obese adults using Walker and Avant's method.
