Summary

This study will use a comparative effectiveness design of two interventions known to reduce running impacts. The study will be conducted at the Spaulding National Running Center. A total of 40 male and female participants, between ages 18-50 years, running 10- 30 miles per week will be recruited from the local running community. All potential subjects will be cleared for physical activity using a Physical Activity Readiness Questionnaire (PAR-Q) and screened via high-speed video to determine their habitual footstrike pattern. Those who are rearfoot strikers will be included and will then be randomized to either an increased cadence (CAD) or a forefoot strike (FFS) intervention group. Standardized running shoes will be provided to both groups for the duration of the study. All participants will attend 2 strength-training instruction sessions with a physical therapist prior to gait-retraining intervention. They will be instructed to perform the learned exercises daily for 4 weeks to prepare the body tissues for forces associated with new gait methods. Subjects will then attend 8 gait-retraining sessions over 2-3 weeks. Sessions will be scheduled as two sequential days of training followed by a day of rest. The gait retraining protocols will be conducted on a treadmill. 3D Motion Capture analysis will be conducted at baseline and at 3 points following intervention (1 week, 1 month, and 6 months).

Conditions

  • Musculoskeletal Injury

Interventions

OTHER

Increased running cadence gait retraining

Runners use an increased cadence, or step rate, 7.5% greater than baseline preferred cadence

OTHER

Forefoot Strike gait retraining

Runners use a forefoot strike running gait instead of a rear foot strike running gait.

OTHER

Strengthening exercises

foot and ankle strengthening exercises performed by all subjects to prepare musculoskeletal tissues for requirements of new running gait.
