The effect of quercetin and citrulline on cycling time trial performance.

Background: There is growing interest in the use of nutrition and dietary supplements to optimize training and time-trial (TT) performance in cyclists. Separately, quercetin (QCT) and citrulline (CIT) have been used as ergogenic aids to improve oxygen (VO) kinetics, perceived effort, and cycling TT performance. However, whether the combination of QCT and CIT can provide additive benefits and further enhance cycling performance production is currently unknown.

Quercetin in Sports and Exercise: A review.

This paper systematically reviews the latest evidence regarding Quercetin's (Q) effect following exercise performance, aerobic and anaerobic exercise, muscle-damaging bouts and highlights blood biomarkers associated with muscle damage and recovery. Google Scholar, Web of Science, and MedLine (PubMed) searches were conducted through July-December 2021. Peer-reviewed studies that investigated Q as a single ingredient or in combination with other ingredients at dosages of 500 mg - 3000 mg, ranging from 15 min-to-1 h prior to exercise bout or chronic dose (7 days - 8 weeks) of consumption were included.

Increased game frequency period crossing Ramadan intermittent fasting decreases fat mass, sleep duration, and recovery in male professional basketball players.

Background: Increased basketball game frequency may affect athlete performances, especially during Ramadan intermittent fasting (RIF). The objective of the present investigation was to assess the impacts of increased game frequency periods crossing the RIF on body composition, sleep habits, indices of well-being, recovery state, and dietary intake in professional male basketball players.

Methods: Twenty-eight professional basketball players participated in this study and were divided into increased-games-frequency (INCR) or normal-games-frequency (NORM) groups.

Measured versus label declared macronutrient and calorie content in Colombian commercially available whey proteins.

Whey protein (WP) supplements have grown in popularity for exercising populations to enhance muscle protein synthesis and promote recovery. The purpose of this investigation was to examine the macronutrient profile, especially protein, of commonly sold protein powder brands in the Colombian (South America) sports supplement market. Eleven popular whey proteins supplements made and sold on the Colombian market were sampled and determined the humidity, ash, total carbohydrates, fat, proteins, and calories (kcal).

Gastrointestinal Hormones, Morphological Characteristics, and Physical Performance in Elite Soccer Players.

Purpose: To determine the relationship between gastrointestinal hormones (leptin, glucagon-like peptide-1), ghrelin, cholecystokinin, peptide YY, morphological characteristics, and physical performances in elite soccer players.

Methods: Q2 Twenty-two elite male soccer players (age = 23.1 [2.

Taurine in sports and exercise.

Background: Taurine has become a popular supplement among athletes attempting to improve performance. While the effectiveness of taurine as an ergogenic aid remains controversial, this paper summarizes the current evidence regarding the efficacy of taurine in aerobic and anaerobic performance, metabolic stress, muscle soreness, and recovery.

Methods: Google Scholar, Web of Science, and MedLine (PubMed) searches were conducted through September 2020.

Prepping for Prevention: An Intervention to Optimize Skin Antisepsis and Peri-Operative Antibiotic Prophylaxis.

The U.S. Centers for Disease Control and Prevention recommend bathing prior to surgery, surgical skin antisepsis, peri-operative antibiotic administration, normothermia throughout the procedure, serum glucose concentration <200 mg/dL throughout the procedure, and hyperoxygenation in the immediate post-operative period to prevent surgical site infection (SSI).

Implementation of cleaning and evaluation process for mobile patient equipment using adenosine triphosphate.

We implemented a cleaning process for mobile patient equipment (MPE) and determined its success using adenosine trisphosphate (ATP) monitoring and data feedback. Following education for staff and ATP data feedback, the data suggest that the MPE cleaning program we implemented was successful.

Evaluation of alcohol use disorders in workplace disability claims.

This article examines alcohol use disorders in the context of work and disability. The authors investigated the problem from a disability perspective and how to determine if alcohol use is functionally impairing the worker and requires workplace disability. Key identifiers for impairment are addressed, including evaluation of treatment intensity, comorbidities,and functional declines.

Mental health issues in the workplace: maintaining a productive work force.

Occupational health nurses must intervene early and validate the conditions and experiences of employees with psychiatric disabilities. Occupational health nurses must ensure employees are receiving appropriate treatment. They must be aware of and prepared to mitigate iatrogenic influences.

Managing mental health disability in the workplace.

Jane is a 51-year-old customer-service representative for a utility company's customer-service call center. She has worked in this capacity for almost 10 years. She was considered an exemplary employee, received commendations at work, and was in line for a promotion to a supervisory position.

Double belt structure of discoidal high density lipoproteins: molecular basis for size heterogeneity.

We recently proposed an all-atom model for apolipoprotein (apo) A-I in discoidal high-density lipoprotein in which two monomers form stacked antiparallel helical rings rotationally aligned by interhelical salt-bridges. The model can be derived a priori from the geometry of a planar bilayer disc that constrains the hydrophobic face of a continuous amphipathic alpha helix in lipid-associated apoA-I to a plane inside of an alpha-helical torus. This constrains each apoA-I monomer to a novel conformation, that of a slightly unwound, curved, planar amphipathic alpha 11/3 helix (three turns per 11 residues).

Perceptions and experiences of two survivors of stroke who participated in constraint-induced movement therapy home programs.

The purpose of this study was to explore and describe the perceptions and experiences of two survivors of stroke who participated in constraint-induced movement therapy (CIMT) home programs. Data sources were analyzed with a phenomenological approach, and common themes were identified. Themes were translated using the Occupational Adaptation frame of reference as a template.
