DARD; Dynamic Ankle Resistance Device Strengthens Anterior Tibial Muscles with Dorsiflexion Resistance

Search DARD on Amazon.com ...

The Dynamic Ankle Resistance Device is an excellent strength trainer for the anterior tibial muscles or front shin muscles that are involved in dorsiflexion of the foot and ankle. Dorsiflexion is the action that moves the forefoot (toe area) toward your head. Plantar Flexion is the action that points the forefoot away from your head (action of the calf muscles). Strong anterior shin muscles (dorsiflexor muscles) help control the foot strike in running by decelerating the way the forefoot hits the ground. Weak muscles cause the foot to slap down hard.  In other words, the muscles that control dorsiflexion also decelerate plantar flexion during a normal distance runner's heel strike or mid-foot/heel strike. It is a strain for the anterior muscles to keep the foot from slapping down during heel strike during running if they are too weak or become fatigued ... and is considered to be a possible cause of "shin splints" (pain on the shins) from over-mileage and other training errors.

The DARD or Dynamic Ankle Resistance Device trains the anterior shin muscles with progressive resistance to help control foot strike during running by strengthening their force capability.

TRX Training Products

Randy Hetrick, a former Navy Seal and Stanford MBA graduate, developed the Total Resistance eXercise (TRX) equipment and the associated Suspension Training bodyweight exercises in the 1990s, and started marketing it in 2005.  During the inception of the training concept, Navy SEAL Squadron Commander, Randy Hetrick, used a jujitsu belt, parachute webbing and sheer ingenuity to develop the first version of the TRX® Suspension Trainer ™.

TRX is now a $60 million per year business.

The field of suspension training is a form of resistance training that can be performed anywhere using bodyweight as resistance for exercises in a variety of multi-planar, compound exercise movements can be performed. Compound exercises work several muscle groups at once, and include movement around two or more joints.

Proponents of suspension training argue that it develops core body strength, as well as joint and muscular stability, reducing the chance of injury. Some sports scientists have expressed concern that weaker individuals may not have the core stability or joint integrity to use the system safely and effectively.

Exercise are utilized with the aim of developing strength, balance, flexibility, and joint stability simultaneously. Suspension training develops physical strength while using functional movements and dynamic positions. The actual term "suspension training" is a trademark of FITNESS ANYWHERE, LLC -- the providers of TRX training equipment, workout programs, and education programs.
