LEARNING OBJECTIVE: This article will provide a thorough, yet general, nutritional workup of and guidelines for a novice runner in preparation for a half marathon. The neo-runner will be led through three stages of nutritional strategies, which include 1) weight loss and improving general nutrition, 2) periodized eating and fueling, and 3) race pre...

A focus on low body weight and body fat content, combined with regulations in some weight-sensitive sports, are considered risk factors for extreme dieting, eating disorders (EDs) and related health consequences among athletes. At present there are, from a health perspective, no generally accepted optimum values for body weight or percentage of fat...

Several winter sports are indoor sports, and while temperatures vary, there has been a trend for warmer indoor conditions. Those working in nutrition with winter sport athletes should evaluate each winter sport and environmental condition separately and focus on the most important nutritional issues. The chapter provides a brief introduction to the...

Successful performers in weight-sensitive sports are characterised by low body mass (BM) and fat content. This often requires chronic energy restriction and acute weight loss practices. To evaluate current use of body composition (BC) assessment methods and identify problems and solutions with current BC approaches. A 40-item survey was developed,...

Very low body mass, extreme mass changes, and extremely low per cent body fat are becoming increasingly common in many sports, but sufficiently reliable and accurate field methods for body composition assessment in athletes are missing. Nineteen female athletes were investigated (mean (SD) age: 19.5 (±3.3) years; body mass: 59.6 (±7.6) kg; height:...

Gymnastics is an aesthetic sport that requires speed, power, and coordination. Dietary assessments of high-level gymnasts indicate that many of these athletes consume less than the recommended amount of energy and some nutrients for their age and training load. It is particularly important that young gymnasts consume sufficient energy and nutrients...

Hydration status has profound effects on both physical and mental performance, and sports performance is thus critically affected. Both overhydration and underhydration - if sufficiently severe - will impair performance and pose a risk to health. Athletes may begin exercise in a hypohydrated state as a result of incomplete recovery from water loss...
