Abstract:There is agreement that optimizing intake of calories, protein, and carbohydrates to fuel muscle will enable athletes to train harder, but translating nutrition knowledge into nutrition behavior is problematic. The efficacy of individual nutrition counseling (INC) on nutrition behavior using objective measurements in competitive athletes has not been investigated. We therefore evaluated the influence of INC on the objective outcomes: oxygen consumption (VO2) at rest, resting energy expenditure (REE) measured by indirect calorimetry, fat-free mass (FFM), and percentage fat of body weight (PF) measured by tetra-polar bioelectrical impedance in varsity cross-country athletes at three time points of pre-during-& post-season.

A block design of 20 male and female competitive cross-country participants, 18 years and older, was randomly divided into experimental and control groups. All participants completed 3-day diet and exercise logs for baseline nutrition information and received a general nutrition team talk, whereas 10 participants received INC based on REE and specifically tailored to each of their food preferences and daily training routines. Special emphasis was placed on timing of meals and snacks and pre- and post-workout fueling choices. Diet logs were analyzed by computer for baseline measures of calories, protein, and carbohydrates. VO2, REE, FFM, and PF were assessed by standard procedures to provide objective outcome measures at three time points.
