Study information

Scientific title

Prevalence in running events and running performance of endurance runners following a vegetarian or vegan diet compared to non-vegetarian endurance runners: The NURMI Study

Acronym

NURMI

Study hypothesis

It is reasonable to assume that a vegetarian or vegan diet is compatible with successful endurance and ultra-endurance performance?

The NURMI Study will be conducted in three steps following a cross-sectional design. Step 1 intends to determine epidemiological aspects of endurance runners (any distance) using a short standardized questionnaire. Step 2 intends to investigate dietary habits and running history from eligible participants (capable of running a half-marathon at least) using an extended standardized questionnaire. Step 3 intends to collect data after a running event on finishing time and final ranking as well as a post-race rating of perceived exertion, mood status, nutrient and fluid intake during the race.

Primary outcome measures

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 measures

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.
