Effects of Probiotic ( 35624) Supplementation on Exercise Performance, Immune Modulation, and Cognitive Outlook in Division I Female Swimmers.

Our aim was to determine the effects of probiotic supplementation ( 35624; 1 billion CFU·d) on exercise performance, immune modulation, and cognitive outlook in collegiate female athletes during six weeks of offseason training. Seventeen National Collegiate Athletic Association (NCAA) Division 1 collegiate female swimmers participated in this two-group matched, double-blind, placebo controlled design. Via stratified randomization, participants were assigned to probiotic ( 35624; = 8) or placebo ( = 9) groups.

Determination of friction and pulling forces during a weighted sled pull.

Pulling or pushing weighted sleds has been included in various exercise programs. Coaches and researchers may wish to calculate work performed or estimate forces during these exercises, which would involve calculating coefficients of friction: static friction coefficient (μs) and dynamic friction coefficient (μd). The purpose of this study was to establish a reliable method for determining μs, μd, and pulling forces while pulling a weighted sled with different loads to quantify horizontal forces and work performed for training, assessment, and/or research.

Intussusception in colorectal cancer.

Adult intussusception is a rare occurrence and, unlike in childhood, is usually associated with an underlying tumor. Although computed tomography (CT) imaging can identify an intussusception and point toward a cause, diagnosis is challenging if it is only intermittent. When an intussusception presents in the context of a known bowel cancer, it is possible to attribute nonspecific abdominal symptoms to the malignant process.
