During our most recent Supertraining Camp, I showed delegates some drills
that may be used for strength, metabolic, agility and “plyometric” training
on the treadmill. Some of these drills involved backward walking and
running, as well as quick changes from forward to backward walking on the
treadmill (take care if you have never tried this before). The following
paper examined some of the benefits of backward running:

Mechanical Power and Muscle Action during Forward and Backward Running

Flynn, TW & Soutas-Little RW

JOSPT; 17(2), Feb 1993, 108-112

Recently, there has been increasing interest in using backward running (BR) Read more…

It is often stated that a muscle lengthens, but all shortening and
lengthening takes place relative to some starting position. In functional
anatomy, the length of a contracting muscle is invariably measured relative
to its resting, unactivated length. During concentric action, the joint angle
decreases while the muscle contracts; during eccentric action, the joint
angle increases while the muscle contracts. During isometric action, the
joint angle remains the same, even though the muscle is contracting.

Isokinetic action does not take place under any natural daily life
conditions, but is the result of movement that is controlled by a special Read more…
