Carbohydrate Mouth Rinsing Improves Softball Launch Angle Consistency: A Double-Blind Crossover Study.
Nutrients
January 2025
Graduate Program in Department of Exercise Health Science, National Taiwan University of Sport, Taichung 404, Taiwan.
(1) Background: Carbohydrate mouth rinsing (CMR) stimulates the central nervous system and improves motor control. However, no studies have examined the effects of CMR on softball batting performance. The purpose of this study was to investigate the effect of CMR on softball batting performance.

Nutrients
December 2024
Department of Physical Education and Sport Science, School of Physical Education, Sport Science and Occupational Therapy, Democritus University of Thrace, 69100 Komotini, Greece.
Background/objectives: Despite being widely promoted, protein supplementation's overall effectiveness during demanding basketball schedules remains unclear. This study investigated whether increased protein intake can accelerate recovery of muscle function during a 6-day congested basketball microcycle consisting of three consecutive games while accounting for the impact of playing time.
Methods: In a randomized, two-trial, cross-over, double-blind repeated measures design, eighteen male basketball players were assigned to a high (High PT) or a moderate (Mod PT) playing time group and participated in two trials, receiving daily either milk protein (PRO trial) or an isoenergetic amount of carbohydrates.
Effect of Creatine Monohydrate Supplementation on Macro- and Microvascular Endothelial Function in Older Adults: A Pilot Study.
Nutrients
December 2024
Department of Health, Nutrition, and Food Sciences, Florida State University, 120 Convocation Way, Tallahassee, FL 32306, USA.
A pilot study was conducted to investigate the effect of four weeks of creatine monohydrate (CrM) on vascular endothelial function in older adults. In a double-blind, randomized crossover trial, twelve sedentary, healthy older adults were allocated to either the CrM or placebo (PL) group for four weeks, at a dose of 4 × 5 g/day for 5 days, followed by 1 × 5 g/day for 23 days. Macrovascular function (flow-mediated dilation [FMD%], normalized FMD%, brachial-ankle pulse wave velocity [baPWV], pulse wave analysis [PWA]), microvascular function (microvascular reperfusion rate [% StO/sec]), and biomarkers of vascular function (tetrahydrobiopterin [BH], malondialdehyde [MDA], oxidized low-density lipoprotein [oxLDL], glucose, lipids) were assessed pre- and post-supplementation with a four-week washout period.

J Clin Endocrinol Metab
January 2025
Adelaide Medical School, University of Adelaide, Adelaide, Australia.
Context: In males of normal weight, intraduodenal administration of calcium enhances the effects of the amino acid, L-tryptophan (Trp), to suppress energy intake, associated with greater stimulation of cholecystokinin (CCK), glucagon-like peptide-1 (GLP-1) and peptide tyrosine-tyrosine (PYY) secretion (key mechanisms underlying the regulation of pyloric motility and gastric emptying), but not gastrin or glucose-dependent insulinotropic polypeptide (GIP).
Objective: Given the implications for the management of obesity, the current study evaluated the effects of calcium, when administered alone and in combination with Trp, on gut hormone secretion, antropyloroduodenal motility and energy intake in males with obesity.
Methods: Fifteen males with obesity and without type 2 diabetes (mean±SD; age: 27±8 years; body mass index: 30±2 kg/m2; HbA1c: 5.
Correction: Results of N = 1 randomized, double-blind, placebo-controlled, cross-over discontinuation trials embedded in clinical practice after longer term methylphenidate use: a pilot study.
