Effects of Dynamic Strength Training to Prevent Lower Limb Injuries Among Novice Long Distance Runners: An Experimental Study

Abstract

Background/Purpose: Novice long distance runners may contribute to develop common lower limb injuries related to running. Strengthening hip or knee alone does not appear to prevent these injuries. Correction of running mechanics along with proper plan of regime for strengthening of lower limb is needed. The purpose of the current study was to investigate the effects of 6 weeks dynamic strength training to prevent lower limb injuries among novice long distance runners. Methods: This was an experimental study including novice runners (n=30, 18-60 years old, <2 years running experience) to evaluate the effects of dynamic strength training program specially designed under the supervision of expert physiotherapists to minimize lower limb injuries and pain. Participants were engaged in a 6-week extensive training program, three times per week using guided program comprising of various forms of exercises to strengthen their lower limb for prevention of common running injuries. Pre and Post “Knee Outcome Survey (KOS)” was measured to evaluate outcome. Results: Knee Outcome Survey Activities of Daily Living Scale (ADLS) pre training mean score was found to be 24.29 ± 5.9 whereas post training effects was 39.19 ± 2.45 with significant p-value of 0.000. In ADLS of KOS Pain variable outcome measure asked symptom that affects activity moderately the responses were 36.7% in pre whereas 0% after training. Weakness was responded mostly affecting activity moderately in 30% patients while after training it was reduced to 0%. Conclusion: A six-week dynamic strength training program may help to reduce lower limb injuries among novice long distance runners under the supervision of skilled physical therapist.
