Plyometrics in the Sand

As we continue to dive into the intricacies of plyometrics, we are going to come across a wide variety of scenarios when training the stretch shortening cycle (SSC). One of the most important variables is the surface on which the training takes place! Plyos in the sand highlight certain qualities of the SSC, and play down the effects of others. 

Why would you want to be jumping and landing on a softer surface in the first place? Well, the first benefit is the reduced impact on the joints compared to landing on hard surfaces. If one of the goals of the session is to protect the athlete from the rigors of hard landings, while still accomplishing quality work, plyos in the sand does that. Mirzaei and company looked at muscle soreness and how plyometrics in the sand affected it. Their study mentioned  that the sand work resulted in decreased muscle soreness, which in turn allowed for more work to be accomplished. (Mirzaei, 2014)

But coach Nate! What about the increased time spent in the amortization phase of the SSC, and the subsequent loss of elastic energy stored because of the increased time spent on the ground when stretching the muscle!?? Don’t worry my readers, it all depends on the goal of the session! The SSC in totality is one of the most powerful mechanisms we humans have that allow us to exert extreme amounts of force. If you take away the ability of one component of the SSC, in this case the eccentric component, the concentric component has to do some work to get the same task completed. This is similar to the max strength phase of training. The movement is slower, the benefit of the SSC is blunted, and a greater emphasis is placed in the concentric ability of the muscle. In the same study I referenced earlier, Mirzaei and company also mentioned that a 6 week plyometric program completed in the sand resulted in increased vertical, static, and long jump with increases in maximal strength, and decreased sprint times (Mirzaei, 2014).  All good things right? But, the study was completed on untrained individuals, and many of those adaptations could be accredited to neural adaptation, which increases the efficiency of the body completing the task. 

In my professional opinion, I do not have a problem with plyometric sand training. It is another stimulus you can expose an athlete to that still promotes quality training while protecting the body from hard landing. As long as the reason behind this training is sound, go ahead! If you goal is to focus on decreasing the amortization phase and getting off the ground as quickly as possible, then the sand is not the place to be.

Jumping, its Role in Training!

Coach Nate Garcia

Plyometrics is an intense exercise training method. The reason someone trains with plyometric exercises is to improve the “stretch shortening cycle” (SSC) of the muscle system. Similar to the energy stored when stretching a rubber band, when you stretch your muscle energy is stored and if the stretch is followed rapidly by muscle shortening action you are able to use this energy to your movement advantage. Whether you know it or not, the SSC is used throughout your daily motion. One example of your daily utilization of the SSC is the use of your calf musculature when walking. Striking the ground with your heel creates a pre-stretch of the muscles that stores some elastic energy. The energy is released as you propel yourself forward off your toes.

A common example of a plyometric exercise is jumping. Jump training is often looked at as an activity reserved for the sports that primarily involve jumping (such as volleyball or basketball). However, what a lot of people neglect to acknowledge is that jumping relates to numerous activities that people perform, like sprinting. When utilized properly, jumping can be used as an efficient and safe way to improve power and sprint capabilities. However, jumping shouldn’t just be reserved for athlete training. The benefits of having the ability to jump not only means improved athletic ability, it also means improved efficiency with everyday tasks such as: traveling the stairs, preventing a fall, picking up objects from the floor, and running!

Just as with any exercise, in order to see progress in jump ability, you have to properly plan for your goals. Total Performance uses various different jumps in order improve power development. Youth athletes, or those with a small training age, must have their volume of plyometrics closely monitored. A high volume of plyometric training can result in overtraining and ultimately be detrimental . Since jumping is an implication of power, and power is defined as work divided by time, in order to train safely, you need to be strong. Research recommends reserving high volume lower body plyometric training for those who have the ability to squat at least 1.5 x your body weight. If one is unable to accomplish this, it doesn't mean you shouldn’t jump, it just means you need to be extra cautious with your volume of jumps. Advanced athletes have the ability to handle a high volume of plyometric training due to their ability to handle intense training activities. Manipulating jump movements is one way to increase difficulty of the movement. For example; requiring the person to jump and land on one foot, jumping backwards, side to side jumping, and a depth jump from height. There are infinite ways to increase the difficulty of a jump and it all depends on the goal of the training.

What is a “high” and “low” volume of plyometrics? As defined by the National Strength and Conditioning Association (NSCA), lower body plyometrics are measured via contacts. A contact is defined as contact with the ground. So, after one jumps and lands, that contact is counted. Beginner contact volume is recommended to be between 80-100 contacts, intermediate contact volume between 100-120, and advanced between 120-140 contacts. Again, the actual amount of plyometrics you complete all depends on your ability, your training goals, and what other training is being performed with plyometrics.

The volume of plyometrics is one of the several variables that can be manipulated in order to achieve training goals. To be discussed in future posts: what those variables include, how to manipulate those variables, and what those manipulations mean for training goal achievement.
