Standard of Care (SOC)
Strength Training Rehabilitation Incorporating Power Exercises (STRIPE)
The SOC rehabilitation group will complete three strength sessions a week. All participants will be provided an educational pamphlet and exercises will be divided into four components - hip abductors, hip extensors, core, and quadriceps muscles. The load magnitude for exercises will be between 60-70% of their 1 repetition max (1RM), with 3 sets of 12 repetitions and a 2-3-minute rest between sets. Time under tension will be prescribed as slow to moderate, with a 2-second concentric phase and 2-second eccentric phase for each exercise. Hip abductor, hip extensor, and core exercises will be initiated during week 1 and continued for the 6-week intervention, while quadriceps focused exercises will be introduced in weeks 3-6.
Those in the STRIPE group will complete two power and one strength training sessions a week. All participants will be provided an educational pamphlet and exercises will be divided into four components - hip abductors, hip extensors, core, and quadriceps muscles. The load magnitude will be greater than 60% of the 1RM, with the goal of continually loading against heavy resistance. Participants will complete 4 sets of 6 repetitions, with 3-5 minutes of rest between sets. Time under tension will be prescribed as <1 second for the concentric phase and 1 second for the eccentric phase of the exercise. The strength training sessions will adhere to same parameters as the SOC. Hip abductor, hip extensor, and core exercises will be initiated during week 1 and continued for the 6-week intervention, while quadriceps focused exercises will be introduced in weeks 3-6.
