Increased risk of lower back injury during hip flexion and extension and overhead standing activities. During extension activities, the lower back can hyperextend more than usual if the hip cannot fully extend. During hip flexion activities, the Iliopsoas can hyperextend spine during hip flexor activities. Risk is compounded when hip flexor inflexibility is combined with abdominal weakness.
– Examples of affected exercises:
– Military press (standing)
– Decline Sit-up
– Lunge (rear leg)
– Lever Back Extension (fulcrum near hip)
– Example assessments
– Lunge Test
– Thomas Test
– Hip Extension ROM
– Example preventative/corrective exercises:
– Kneeling Hip Flexor Stretch
– Quadriceps Stretch
