Understanding the balance between increasing tendon elasticity and under/ over training is a on going problem in the sports era. Coaches and trainers need to be sure that clients and athlete’s are getting the balance of hard training and plyometrics that they need. Meaning, if you work as a sales associate and spend many hours sitting down, plyometric training might be necessary 2-4 times a week to build of tendon endurance, ankle stiffness, mobility and strength. A conditioned, WELL trained athlete needs LESS plyometrics to be effective. In my scientific opinion, this is partially the reason for the increase in tendinitis and Achilles tendon tears. Great athlete’s are either not training correctly with errors in biomechanics and kinesiology principles; or they are overtraining causing tendons to be tired. Tendons are not like muscles or bones. We can keep our muscular strength, break a bone, tear a muscle and recover in months. Tendons age quicker, so the plan of attack and procedures for duality in athletic performance and recover is not being met by the so called “best” trainers. They are making chronic errors. Overtime, my goal is the implement change to foster more sense into the sports community. I do not do these drills for 20 minutes. I perform 1-2 heavier strength bouts at low volume, and do these for nor more than 2-3 sets of 8-12 on each leg. That’s it! For the elite, sometimes less is more. For the person trying to catch up not jumping for 10 years, be active in plyo 2-4 times a week.
