Position Statement: The International Society of Sports Nutrition (ISSN) presents this position based on a critical examination of literature surrounding the effects of essential amino acid (EAA) supplementation on skeletal muscle maintenance and performance. This position stand is intended to provide a scientific foundation to athletes, dietitians, trainers, and other practitioners as to the benefits of supplemental EAA in both healthy and resistant (aging/clinical) populations. EAAs are crucial components of protein intake in humans, as the body cannot synthesize them. The daily recommended intake (DRI) for protein was established to prevent deficiencies due to inadequate EAA consumption. The following conclusions …

Coping Mechanisms For Lymphedema: An Analysis Of Patient Experiences., Claudia Admoun, Harvey N. Mayrovitz

HPD Articles

Background and objective Lymphedema is a condition caused by impaired lymphatic function. Acquired lymphedema is often due to neoplasia, infection, trauma, or radiation damage. Most patients rely on advice from fellow patients and personal research to manage their symptoms. We believe coping mechanisms for lymphedema can be more streamlined and made easily accessible if the most common effective strategies are determined and collected in a single repository for reference. To that end, we aimed to assess the experiences of lymphedema patients and the coping mechanisms they employed. Methods Feedback from lymphedema patients was obtained using a 19-item questionnaire-based survey distributed …

Creatine Supplementation And Endurance Performance: Surges And Sprints To Win The Race., Scott C. Forbes, Darren G. Candow, Joao Henrique Falk Neto, Michael D. Kennedy, Jennifer L. Forbes, Marco Machado, Erik Bustillo, Jose Gomez-Lopez, Andres Zapata, Jose Antonio

Creatine supplementation is an effective ergogenic aid to augment resistance training and improve intense, short duration, intermittent performance. The effects on endurance performance are less known. The purpose of this brief narrative review is to discuss the potential mechanisms of how creatine can affect endurance performance, defined as large muscle mass activities that are cyclical in nature and are >~3 min in duration, and to highlight specific nuances within the literature. Mechanistically, creatine supplementation elevates skeletal muscle phosphocreatine (PCr) stores facilitating a greater capacity to rapidly resynthesize ATP and buffer hydrogen ion accumulation. When co-ingested with carbohydrates, creatine enhances glycogen …

Based on a comprehensive review and critical analysis of the literature regarding the nutritional concerns of female athletes, conducted by experts in the field and selected members of the International Society of Sports Nutrition (ISSN), the following conclusions represent the official Position of the Society: 1. Female athletes have unique and unpredictable hormone profiles, which influence their physiology and nutritional needs across their lifespan. To understand how perturbations in these hormones affect the individual, we recommend that female athletes of reproductive age should track their hormonal status (natural, hormone driven) against training and recovery to determine their individual patterns and …

The Effects Of Consuming A High Protein Diet (4.4 G/Kg/D) On Body Composition In Resistance-Trained Individuals, Jose Antonio, Corey Peacock, A. Ellerbroek, B. Fromnoff, Tobin A. Silver

Department of Health and Human Performance Faculty Articles

BACKGROUND:

The consumption of dietary protein is important for resistance-trained individuals. It has been posited that intakes of 1.4 to 2.0 g/kg/day are needed for physically active individuals. Thus, the purpose of this investigation was to determine the effects of a very high protein diet (4.4 g/kg/d) on body composition in resistance-trained men and women.

METHODS:

Thirty healthy resistance-trained individuals participated in this study (mean ± SD; age: 24.1 ± 5.6 yr; height: 171.4 ± 8.8 cm; weight: 73.3 ± 11.5 kg). Subjects were randomly assigned to one of the following groups: Control (CON) or high protein (HP). The CON …
