Day 337 - Plyometric Safety Considerations
Pretraining Evaluation of the Athlete
Every individual that wishes to begin plyometric exercise should evaluate their current health and fitness status to determine if they are an appropriate candidate to follow such an intense training regimen.
Technique - Individuals should be not only physically mature, but mentally mature enough to be able to follow instructions to follow correct form and technique. For example, proper technique should be followed to maintain control of the body's center of gravity. A specific example of this would be the body's shoulders staying in line with the knees when performing jumping type exercises.
Strength - For lower body plyometrics, the NSCA recommends that an individual's 1RM squat should be at least 1.5 times their body weight in order to be strong enough to perform plyometric exercises. For upper body, the bench press 1RM should be at least the individual's body weight.
Speed - Again, for lower body plyometrics, the NSCA recommends that an individual be able to 5 reps of the squat with 60% body weight in 5 seconds or less. Upper body speed should be able to perform 5 bench press reps of 60% body weight in 5 seconds or less.
Balance - Plyometric exercises are not always done in a vertical plane, as some plyometric and agility exercises require lateral or horizontal displacements. An individual should have a good level of balance and spatial control over their body so that they reduce their risk for injury when exercising. An example of a balance test would be an individual balancing on one leg for 30 seconds without falling.
Physical Characteristics - Joint disorders, back disorders, or other disorders that affect an individual's ability to control their limbs in a controllable manner could increase the risk of injury. Not only that, but the NSCA recommends that individuals that are over 220 pounds may be at an increased risk of injury due to the immense stresses and strains placed on the body.
Equipment and Facilities
Going beyond the physical demands required for plyometric exercise, certain equipment as well as the area used should be of ideal conditions that are detailed below.
Landing Surface - As shock-absorbing as possible such as a grass field, suspended floor, or rubber mats are the best choices.
Training Area - This category is entirely dependent on the exercise being conducted. Bounding drills may require large horizontal spaces, whereas standing power jumps could be done in a small relative space.
Equipment - Boxes or platforms used for depth jumps, jumping on or off of, should have non-slip surfaces to prevent slipping and injury.
Proper Footwear - Cross training shoes are the best fit for plyometric exercises as they generally have more support for lateral movements of the feet and ankles.
Depth Jumps - This exercise in particular warrants its own category because a height of 48 inches (1.2m) is the recommended maximum height from the NSCA as jumping from a platform any higher than this could cause injury.
