The purpose of this study was to determine the dietary adequacy of 12 collegiate cross-country runners during a competitive season. Four-day diet records were collected twice during the season and analyzed for total daily energy, macronutrients, vitamin A, vitamin C, thiamin, riboflavin, niacin, vitamin , folate, iron, magnesium, zinc, and calcium. Mean energy intake (3,248 ± 590 kcal) was not significantly different from estimated mean energy expenditure (3,439 ± 244 kcal). Week 8 mean prealbumin levels were within normal limits (26.8 ± 2.8 mg/dl). Mean daily CHO intake was 497 ± 134 g/day (61.2%). Three to four hours prior to competition a pre-race meal was consumed; it contained 82 ± 47 g CHO. Posteompetition CHO intake was delayed an average 2.5 hr; at that time approximately 2.6 ± 0.69 g CHO/kg body weight was consumed. The athletes appeared to demonstrate dietary adequacy with the exception of timing of posteompetition carbohydrate consumption.

AbstractAchilles tendon structure differs between trained distance runners and healthy controls, but the progression of tendon remodeling over the course of a competitive season is poorly understood. Therefore, the purpose of this study was to quantify Achilles tendon structure at the beginning and completion of a cross country season. We hypothesized that athletes who did not develop tendinopathy would not present with changes in tendon structure. Ultrasound assessments of the right Achilles tendon mid-substance were performed to quantify tendon organization, thickness, and echogenicity. Subjective structural measures and reported outcomes were also collected to determine if tendinopathy was present in any of the subjects. None of the subjects developed symptomatic tendinopathy over the course of the competitive season, but one runner did show signs of mild neovascularization. Tendon organization and echogenicity did not change over the course of the season. Tendon thickness increased by 7% (P < 0.001) but the effect size was small (d = 0.36). Runners who do not develop symptomatic tendinopathy have habituated tendon structure that may serve as a protective mechanism against the rigors of distance running. Monitoring tendon structure may serve as a means of detecting signs of structural indicators of tendinopathy prior to the presentation of symptoms.
