Comparison of the effects of velocity-based vs. traditional resistance training methods on adaptations in strength, power, and sprint speed: A systematic review, meta-analysis, and quality of evidence appraisal.

We estimated the effectiveness of using velocity feedback to regulate resistance training load on changes in muscle strength, power, and linear sprint speed in apparently healthy participants. Academic and grey literature databases were systematically searched to identify randomised trials that compared a velocity-based training intervention to a 'traditional' resistance training intervention that did not use velocity feedback. Standardised mean differences (SMDs) were pooled using a random effects model.

Lie for Me: Developmental Trends in Acquiescing to a Blatantly False Statement.

A pair of studies demonstrates that simply asking children to make a blatantly false accusation in the guise of helping others can result in both immediate and long-term false claims. In the pilot study, the initial willingness to make a blatantly false statement was associated with some children making false statements a week later despite being told that the first interviewer had made mistakes during the initial interview. On a positive note, the majority of participants accurately stated that they did not have first-hand knowledge of their accusation's accuracy.

Regulation of rat proximal intestinal glycolytic enzyme activity by ileal perfusion with glucose.

Specific activities of the glycolytic enzymes fructose-1-phosphate aldolase, fructose-1,6-diphophate aldolase, and pyruvate kinase, are higher in rat duodenum and jejunum than in ileum. Whether this gradient reflects the failure of dietary sugars to reach the ileum in high concentrations is unknown. Rats were first fed a carbohydrate-free diet for 3 days, which virtually removed the proximal-distal gradient of enzyme specific activities.

Regional variation in glycolytic enzyme adaptation to dietary sugars in rat small intestine.

This investigation evaluated the adaptive response of the glycolytic enzymes, fructose-1-phosphate aldolase, fructose-1, 6-diphosphate aldolase, and pyruvate kinase, to dietary sugars throughout the small intestine. In addition, the effect of prior diet on this adaptive response and on the enzyme distribution pattern along the small intestine was studied. Rats were fed 40% glucose, 68% sucrose or carbohydrate-free diets for 6 days (baseline diet), followed by one of three isocaloric test diets (40% glucose, 68% sucrose or carbohydrate-free for 3 days.
