A Cell Proliferation and Inflammatory Signature Is Induced by Lawsonia intracellularis Infection in Swine.

causes porcine proliferative enteropathy. This is an enteric disease characterized by thickening of the wall of the ileum that leads to decreased growth of animals and diarrhea. In this study, we investigated the host response to infection by performing transcriptomic and pathway analysis of intestinal tissue samples from groups of infected and noninfected animals at 14, 21, and 28 days postchallenge.

The effects of zinc amino acid complex supplementation on the porcine host response to Lawsonia intracellularis infection.

Lawsonia intracellularis is among the most important enteric pathogens of swine and antibiotic alternatives are needed to help mitigate the negative effects of infection. Zinc is an essential trace mineral known to be crucial for maintaining intestinal barrier function and proper immune response. In this study, we investigated the porcine host response to L.

Match-Play Running Performance and Exercise Intensity in Elite International Women's Rugby Sevens.

Malone, S, Earls, M, Shovlin, A, Eddy, A, and Winkelman, N. Match-play running performance and exercise intensity in elite international women's rugby sevens. J Strength Cond Res 34(6): 1741-1749, 2020-The aim of the current investigation was to describe the running and physiological performance demands of elite women's rugby sevens match-play.

Differential effects of attentional focus strategies during long-term resistance training.

The purpose of this study was to investigate the effects of using an internal versus external focus of attention during resistance training on muscular adaptations. Thirty untrained college-aged men were randomly assigned to an internal focus group (INTERNAL) that focused on contracting the target muscle during training (n = 15) or an external focus group (EXTERNAL) that focused on the outcome of the lift (n = 15). Training for both routines consisted of 3 weekly sessions performed on non-consecutive days for 8 weeks.

Physical-Preparation Recommendations for Elite Rugby Sevens Performance.

Rugby sevens, a sport new to the Olympics, features high-intensity intermittent running and contact efforts more than short match durations, normally 6 times across 2 to 3 d in a tournament format. Elite rugby sevens seasons often include over a dozen competitive tournaments over less than 9 months, demanding deliberate and careful training-stress balance and workload management alongside development of the necessary physical qualities required for competition. Focus on running and repeated power skills, strength, and match-specific conditioning capacities is advised.
