Plyometric training is a versatile and effective method for enhancing various aspects of athletic performance, including running economy, agility, speed, and muscle power. Its benefits extend to both adult and young athletes, making it a valuable addition to training programs across different sports.
Plyometrics, also known as “jump training,” is a form of exercise that involves rapid and repeated stretching and contracting of muscles, designed to increase muscle power. This training method is widely used by athletes to enhance performance in sports that require explosive movements such as sprinting, basketball, and soccer.
Mechanism and Benefits
Plyometric exercises typically involve jumping, bounding, and hopping movements that exploit the stretch-shortening cycle of muscles. This cycle involves a pre-stretch or countermovement that stores elastic energy in the muscle, followed by an explosive contraction that releases this energy, resulting in a more powerful movement.
Improvements in Running Performance
Research has shown that plyometric training can significantly improve running economy (RE) and distance-running performance. For instance, a study demonstrated that a 6-week plyometric program led to a 2.7% improvement in 3-km running performance and enhanced RE at various velocities. These improvements were attributed to increased lower leg musculotendinous stiffness (MTS) and better utilization of elastic energy during running1.
Enhancements in Agility and Speed
Plyometric training is also effective in improving agility and speed. A study involving athletes showed that a 6-week plyometric training program significantly enhanced agility, as measured by the T-test and Illinois Agility Test, and reduced ground reaction times3. Another study found that plyometric exercises improved sprint acceleration performance, particularly when adequate recovery time was provided between exercises5.
Benefits for Young Athletes
Plyometric training is not limited to adult athletes; it is also beneficial for young athletes. Research on preadolescent soccer players revealed that plyometric training led to significant improvements in speed, leg muscle power, leg strength, agility, and soccer-specific performance measures such as kicking distance2. Additionally, unilateral plyometric training was found to be more effective than bilateral training in enhancing strength, speed, and power in young soccer athletes8.
Neuromotor Control and Muscle Activation
Plyometric training can also correct altered neuromotor control and improve muscle activation. For example, a study on triathletes showed that adding plyometric exercises to regular endurance training improved neuromotor control during running after cycling, which is crucial for triathlon performance4. Another study found that plyometric training increased maximum voluntary contraction (MVC) strength and neural activation of the knee extensors during various types of muscle contractions7.
