Accommodating resistance (sometimes referred to as semi-isokinetic resistance applications) involves a number of methods of altering the strength curve or the tension throughout the range of movement of a specific exercises.
This method was popularized more recently with Westside Barbell training however this technique dates back much further and involves more than just chains and bands.
The initial method of accommodating resistance utilized isokenetic machines and then latter with cam machines (Nautilus-type equipment). These had some advantages but many disadvantages especially due to the fixed plan of movement. These may be used in specific exercises and limited use.
The more commonly used method used today involves chains and bands.
Possible reasons for using Accommodating Resistance:
- Strength levels vary through normal exercise ROM
- Strength gains can be limited by “weak point” of movement ROM
- As the client reach top of lift they naturally slow down, limiting total Rate of Force Development
- Chains & Bands allow the client to maximally stimulate muscle through entire ROM
- Accommodating resistance allows the client to safely overreach during the eccentric phase
- Accommodating resistance with chains lowers overall load on the joints
When the effectiveness of combined method (band/chains and weights) and free weight training are compared the results are clear.”
- Greater mean and peak forces were generated throughout the movement
- The stronger eccentric loading and brief transition period provided neuromuscular stimulation similar to that found in plyometric training
- The force generated during the later stages increased, in strong contrast to that of a normal movement in which force production tends to decrease significantly.
