Brief Summary

Running is a natural part of human locomotion and humans have been running for million of years. In modern society, running has become a popular way of exercise and is undertaken by many people worldwide, possibly because it provides a cheap and easily accessible form of exercise, and the positive effects of running on health and fitness are well known. Unfortunately, running is also associated with a high risk of injury.

The purpose of this project is to investigate how a running schedule which focuses either on running distance or running speed influence the overall risk of injury and the types of injury sustained in recreational runners.

Detailed Description Trails directed at investigating differences in injury risk in relation to the focus of the running schedule have been conducted without any firm conclusions. People engaged in recreational running or choosing running as a new and active lifestyle needs guidance on which running schedules minimize the injury risk, aiding their chance of an active lifestyle and possibly reversing the increase in people developing a lifestyle disease. To develop running schedules minimizing the risk of injury, an understanding of the mechanisms that the different training variables impose on the human body is necessary. The existing literature on running intensity and the development of injuries show conflicting result. More studies are necessary to ascertain if there is a relationship between the intensity of running. In such studies, it is important to include other training variables in the analysis and to quantify running exposure using an objective method of measuring the relative intensity and absolute volume.
Study Type  ICMJE Interventional
Study Phase  ICMJE Not Applicable
Study Design  ICMJE Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Double (Participant, Investigator)
Primary Purpose: Prevention
Condition  ICMJE Running Related Injuries
Intervention  ICMJE
  • Behavioral: An 8 week preconditioning period
    Receipt of a weekly running schedule through an online training diary.
  • Behavioral: 16 week training period
    Receipt of a weekly running schedule through an online training diary.
Study Arms  ICMJE
  • Active Comparator: Preconditioning running
    An 8 week preconditioning period. The variables of interest are running distance and running intensity: running speed >80% VO2max (maximal oxygen uptake).
    Intervention: Behavioral: An 8 week preconditioning period
  • Active Comparator: Follow-up period

    The Volume group progress 23% in total weekly running distance in the last adaptation week in the prior 4 week block.

    The Intensity group progress 23% in weekly distance of running above 80% VO2 max (maximal oxygen uptake), based on the distance of running above 80% VO2max in the last adaptation week in the prior 4 week block.

    Intervention: Behavioral: 16 week training period
