Brief Summary

The aim of this study is to examine the effects of plyometric training on biceps femoris longus (BFl) and vastus lateralis (VL) muscle architecture in individuals with anterior cruciate ligament reconstruction (ACLR). Individuals will be randomly placed into training and control groups. Measurements of muscle architecture will be taken bilaterally from BFl and VL muscles by means of an ultrasound device. Functional performance will be evaluated with the International Knee Documentation Committee score and the single leg jump test. Following the initial evaluations, individuals in the training group will receive plyometric training. Evaluations of muscle architecture and functional performance will be taken again from the individuals in the training and control groups at the end of the 4th and 8th weeks. The received ultrasound images will be calculated through the MicroDicom software. In-group and between-group comparisons will be analyzed using the Statistical Package for the Social Sciences program and appropriate tests.

Study Arms (2)

Plyometric Training Group

EXPERIMENTAL

Individuals in the plyometric training group will receive plyometric training. In this training, individuals will not participate in a real plyometric training. Volunteers will watch videos to be prepared (action observation) and imagine them performing those exercises (motor imagery). Except for one session that will be applied every two weeks, all other trainings will be given on the basis of telerehabilitation via distance education tools.

Other: Plyometric Exercise

Control Group

NO INTERVENTION

Volunteers in this group will not participate in any training.

Interventions

Plyometric Exercise OTHER

Plyometric training consisting of ten different exercises \[vertical unilateral and bilateral counter movement jump, horizontal unilateral and bilateral counter movement jump, drop jump (30 cm), squat jump, step-hop (20 cm), 180 degree rotation in transverse plane, frontal plane hurdle jump (20 cm) and sagittal plane hurdle jump (20 cm)\] for 8 weeks, 3 sessions per week. Individuals will not participate in a real plyometric training. Volunteers will watch videos to be prepared (action observation) and imagine them performing those exercises (motor imagery)

Plyometric Training Group
