This book excerpt describes field methods for assessing body composition that are portable and easy to use for assessment of several people in a short time period.

Dietary fat has both long-term and short-term effects on an athlete and athletic performance. “Fat loading” as a strategy to improve athletic performance remains unproven.

The ketogenic diet, while controversial and a highly polarizing subject, has demonstrated promise as an alternative dietary strategy for weight management.

Time-restricted eating (TRE) is an application of intermittent fasting where an individual consumes their calories in a specific eating window (e.g., 8 hours) followed by a prolonged fasting window (e.g., 16 hours). Several randomized controlled trials have analyzed the combined effect of resistance training (RT) and TRE on physical adaptations, including fat mass (FM) loss, fat-free mass (FFM) retention, hypertrophy, local muscular endurance, power, and strength. In this mini review, we highlight the methodology and results from these studies and conclude by providing practical application suggestions for fitness professionals striving to maximize RT + TRE with their clientele. Generally, RT + TRE leads to positive body composition changes, including FM loss and FFM retention, which culminates in improved body fat percentage. Similarly, RT + TRE consistently stimulates positive neuromuscular adaptations, such as increased hypertrophy, local muscular endurance, power, and strength. When positive changes are not observed, and when safely implemented, RT + TRE rarely confers negative effects on the abovementioned adaptations. In short, RT + TRE may be a beneficial dietary and exercise strategy to improve body composition and muscular fitness. However, there are several caveats for practitioners to consider, which are discussed at length in this article.

Guy Leahy writes a review of the research relating to the tactical population from presentations and research from the 65th Annual Meeting of the American College of Sports Medicine (ACSM).

Diets moderately higher in protein and slightly lower in carbohydrate may be beneficial when it comes to weight loss and improving body composition, as well as for sport performance.

This article is part of a continuing series of tactical strength and conditioning (TSAC) research reviews. It is designed to bring awareness to new research findings of relevance to tactical strength and conditioning communities.

The purpose of this article is to provide fitness professionals with best practices on creating a program that uses red light therapy to aid in weight loss and weight management.

This study investigated the differences in off-ice and on-ice fitness characteristics between elite and subelite male ice hockey players.
