The objectives of the study are comparing the risk of injury and the running performance among novice runners with two different training programmes. The first programme has less running volume but more strengthening than the second one which is a normal running programme with no specific strengthening program.

This study will provide necessary information for a multicentric study to come. The information needed for this bigger study are the sample size, the attrition rate, the drop-out rate and the feasibility of the timeline.

The objectives of the study are comparing the risk of injury and the running performance among novice runners with two different training programmes. The first programme has less running volume but more strengthening than the second one which is a normal running programme with no specific strengthening program.

Hypothesis: A training programme with less running but strengthening exercises based on interval technique and strength could have similar or better results regarding running related injuries and performance compared to a normal training programme.

The experimentation will take place in Louvain-la-Neuve in Belgium. Most of the common trainings will take place on the 400m outdoor track field of of the University. A sample of local university students will be drawned. The sex proportion of the participants should be representative of the population (non-runners population), thus 50/50. They will have to be non-runners in good and healthy condition. A non-runner is defined as someone who did not practice regular running at least twice a week for the last 6 months and could not perform a 10km at enrolment.

50 participants will take part in this experimentation. They will be randomized into 2 groups of 25. The investifator hypothesize that 40 participants will follow the study until the end.

Inclusion Criteria:

1. they were between 18 and 30 years
2. matched our definition of novice runners
3. had not sustained a musculoskeletal injury in the past six months
4. agreed to subscribe to an online application and to report each running training on this platform.

A novice runner was defined as someone who has not been running more than once a week for more than six months. The participants were systematically excluded if they did not match the interval of age, were not considered as novice runners, i.e., ran twice or more times a week for more than six months

Exclusion Criteria:

• They were also excluded if they had sustained an injury in the last 6 months or suffered from any musculoskeletal or neurological disorders

The investigator were blinded for group distribution and randomisation. They also were the outcome assessor and were therefore kept blinded.
