Which of the following should be assessed before beginning a lower body plyometric training program?

• A. 1 and 3 only
• B. 2 and 4 only
• C. 1, 2, and 3 only
• D. 1, 2, 3, and 4

Answer: (D)

Before starting a lower-body plyometric program, you need to verify readiness across several domains because plyometrics place high forces on muscles, tendons, and joints and rely on solid technique and control. Start by confirming a strong strength and power base in the legs, since adequate force production and control are essential to handle the rapid stretch-shortening cycle. Then examine movement technique and landing mechanics to catch faulty patterns—such as excessive knee valgus or insufficient knee bend—that could escalate joint stress during plyometric reps. Also check mobility and range of motion at key joints, especially the ankles, hips, and knees, to ensure proper alignment and absorption of forces through full movement. Finally, review injury history and general medical readiness to identify any conditions that would warrant modification or postponement. When all four areas meet acceptable criteria, progression into plyometrics is appropriate.
