New RUNSAFE-based publication

Daniel Ramskov et al. has published the manuscript in Journal of Orthopaedic & Sports Physical Therapy.

RUNSAFE now presents a new article related to injury etiology entitled "Progression in Running Intensity or Running Volume and the Development of Specific Injuries in Recreational Runners: Run Clever, a Randomized Trial Using Competing Risks". The article originates from the Danish RUNCLEVER trial, which was led by Daniel Ramskov assisted by Sten Rasmussen, Henrik Sørensen, Martin Lind, Erik Parner and Rasmus Nielsen.

  

ABSTRACT

Study Design

Randomized clinical trial, etiology.

Background

Training intensity and volume have been proposed to be associated with specific running-related injuries. If such an association exists, secondary preventive measures could be initiated by clinicians based on symptoms of a specific injury diagnosis.

Objectives

To test the following hypotheses: (i) A running schedule focusing on intensity will increase the risk of sustaining Achilles tendinopathy, gastrocnemius injuries and plantar fasciitis compared with hypothesized volume-related injuries. (ii) A running schedule focusing on running volume will increase the risk of sustaining patellofemoral pain syndrome, iliotibial band syndrome and patellar tendinopathy compared with hypothesized intensity-related injuries.

Methods

Healthy recreational runners were included in a 24-week follow-up, divided into 8-week preconditioning and 16-week specific focus-training. Participants were randomized to one of two running schedules: Schedule Intensity(Sch-I) or Schedule Volume(Sch-V). Sch-I progressed the amount of high intensity running (?88% VO2max) each week. Sch-V progressed total weekly running volume. Global positioning system watch or smartphone collected data on running. Running-related injuries were diagnosed based on a clinical examination. Estimates were risk difference (RD) and 95%CI.

Results

Of 447 runners, a total of 80 sustained an injury (Sch-I n=36; Sch-V n=44). Risk of intensity injuries in Sch-I were: RD2-weeks=-0.8%[-5.0;3.4]; RD4-weeks=-0.8%[-6.7;5.1]; RD8-weeks=-2.0%[-9.2;5.1]; RD16-weeks=-5.1%[-16.5;6.3]. Risk of volume injuries in Sch-V were: RD2-weeks=-0.9%[-5.0;3.2]; RD4-weeks=-2.0%[-7.5;3.5]; RD8-weeks=-3.2%[-9.1;2.7]; RD16-weeks=-3.4%[-13.2;6.2].

Conclusion

No difference in risk of hypothesized intensity and volume specific running-related injuries exist between running schedules focused on progression in either running intensity or volume.
