Health Condition(s) or Problem(s) studied

Diet and running performance
Nutritional, Metabolic, Endocrine

Intervention(s)

We assess dietary and running habits, running events, as well as quality of life with online questionnaires only.

Primary Outcome(s)

In addition to running performance adjusted to performance level, the primary outcome is the prevalence of types of diets (omnivorous, vegetarian, vegan) among runners attending running events. Individual finishing time will be measured by the running events professional timing system and will be calculated as percentage of the overall winner’s time.

Secondary Outcome(s)

Outcomes from Step 1 are: nationality, sex, age, body weight, height, BMI (calculated), type of diet, attended races in past two years, finished running distances, personal best time on each distance, number of planned events for 2014/2015, in-race food and fluid consumption, daily/weekly training frequency, daily/weekly training load, period of preparation for main event, and aim of race participation.
Outcomes from Step 2 are: years of running experience, motivation for running then and now, assisted training, years of race experience, training intensity, medium/long-term goal of racing, additional specific kinds of training, specific diet including supplements, specific training/diet prior to race, diet on day of rest/training/race, pre/in/post-race diet, specific gear, relevant medical measures, and quality of life and health-related behavior.
Outcomes from Step 3 are: pre-race: body weight (including clothing and shoes). In-race: individual finishing time, individual runtime as % of overall winners time (calculated), ranking, calculated pace, temperature, wind, air pressure, humidity, sunlight. Post-race: body weight (including clothing and shoes), calculated weight loss, RPE (Borg) whole body/respiratory/legs, mental mood, fluid and nutrient intake including breakfast, and dietary strategy during race.
