Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Participants will be asked to review the informed consent and consent to the study prior to any study procedures. The study will consist of 2 testing sessions and an 8 week intervention (2 visits per week) at the UF\&Shands Orthopaedics and Sports Medicine Institute. The testing sessions will include clinical measures of knee impairments, questionnaires, biomechanical analysis and functional performance testing.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Plyometric Exercise - High intensity
The exercises should produce a higher peak vertical ground reaction force than those in the low group based on literature findings (e.g. single leg jumps, jumps from higher heights, higher percent effort).
Plyometric Exercise
Treatment sessions include a combination of running, jumping and agility activities (plyometric exercise). Each rehabilitation session will also include an abbreviated, standardized program of lower extremity strengthening (leg press, machine squats, knee extensions; 3 sets x 10 repetitions each), flexibility (standing gastrocnemius and quadriceps stretch, hamstrings stretch in long-sitting; 2 x 30 seconds each) and proprioception (standing on foam and a tilt board; 3 x 30 seconds each).
Plyometric Exercise - Low intensity
A lower peak vertical ground reaction force will be generated in the low intensity group compared to the high intensity group based on findings in the literature (e.g. lower box heights, only two-legged jumps, lower percent effort)
Plyometric Exercise
Treatment sessions include a combination of running, jumping and agility activities (plyometric exercise). Each rehabilitation session will also include an abbreviated, standardized program of lower extremity strengthening (leg press, machine squats, knee extensions; 3 sets x 10 repetitions each), flexibility (standing gastrocnemius and quadriceps stretch, hamstrings stretch in long-sitting; 2 x 30 seconds each) and proprioception (standing on foam and a tilt board; 3 x 30 seconds each).
