Contributing Factors to Change-of-Direction Ability

23 Nov

marshall_faulk[1]Regardless of the sport you play, strength and speed are “difference makers.”  And, although linear sprint speed is important, most athletes will need to change direction while moving at high-speed.

This is another area where strength training becomes important to the athlete’s development.

According to a study from the Journal of Strength and Conditioning Research, “Change-of-direction ability… would be best improved through increases in an athlete’s strength and power while maintaining lean muscle mass.” (Delaney, et. al.)

Since change-of-direction ability is heavily dependent on relative strength and power, the development of these attributes through the core, hips, and lower extremities has a positive effect on change-of-direction (COD) performance.  Research shows a high correlation between 1-repetition maximum/body mass and COD in exercises like squats and deadlifts.

In addition to the squat and deadlift exercises, the leg press and split squat are also beneficial to the development of hip and leg drive.

Single-leg exercises, like the single-leg squat, step-up, and Bulgarian split squat, add an element of balance and stability to your lower-extremity strength development.

Plyometric exercises, like box jumps and depth jumps, can help you build explosive power, improving the amount of force you are able to generate against the ground.

Since long-term (>2 years) strength training improves COD performance, it is recommended as early as childhood and adolescence.  Consult with a knowledgeable, experienced strength and conditioning professional for guidance regarding an age-appropriate, well-designed, and well-supervised program.

Should You Do Plyometric Training on Consecutive Days?

12 Jun

plyometric_boxes[1]In most sports, the ability to produce explosive effort is an important component of performance.  Plyometric training (PT) is commonly used to increase/improve an athlete’s ability to sprint, jump, and change direction.  Additionally, PT may increase endurance performance in sports like basketball and soccer.

Given the high-intensity nature of plyometric training, most research recommends 24-48 hours of rest between PT training sessions.  At our facility, we favor twice-weekly PT training sessions, regardless of the number of weekly training days (e.g., if an athlete trains 3-4 days per week, two of those days include PT).

Occasionally, due to conflicts and other obligations and responsibilities, some of our athletes can only train twice per week and on consecutive days.

A recent Journal of Strength and Conditioning Research study compared twice-weekly plyometric training — 140-260 jumps per session — with groups of athletes given 24-48 hours (1-2 days) of rest between sessions, and those training on consecutive days.

“Although it has been recommended that plyometric drills should not be conducted on consecutive days, the study shows that plyometric training applied twice weekly on consecutive or nonconsecutive days results in similar explosive and endurance adaptations…” (Ramirez-Campillo, et. al.)

If necessary, it appears that consecutive plyometric training days are safe and effective.
