1. AR strengthens ancillary and stabilizing muscles
2. AR improves technique, helping to reduce sticking points whether from muscular or technical Issues
In consideration of muscular weakness as the issue:
This just furthers my previous point that the nonlinear addition of resistance in accommodating resistance work will cause the ancillary and stabilizing muscles involved to constantly be at work during the lift. Even more so as the lift progresses and reaches the end. The areas in which athletes tend to feel slow in their lifts, and termed ‘sticking points’, are the mid-regions and lock outs of a lift. Dialing in on these areas more frequently and progressively will produce a more efficient and effective power lift from beginning to end, reducing the event of ‘sticking points’.
On more of the technical side:
With the use of bands especially for accommodative resistance training, your body is placed in the correct position of a lift to begin with and because of where the bands position is pulling, your body will be forced to move through the correct range of motion of the lift and forced to correct any compensating habits in the process. By performing AR in a program consistently, your body will be trained to automatically adjust to a load with the correct movement pattern and negate its previous inefficient technical patterns as the load increases.
3. AR increases control in the decent as well as power output/acceleration in the accent
- During the decent with AR there has to be an increase in control and stability as to not allow the resistance to pull you down faster than gravity
- During the accent the body has to work against an increasingly amount of resistance with drive and force to get to and complete the lock out
Control of a movement is imperative in the decent of a lift, but coming out of it requires power. Speed is power, so focusing in on that drive in your programming amplifies the ability to complete a lift at heavy loads. Adding resistance to the powerlifts, forcing one to work harder in the accent, will increase the acceleration of the bar and mental drive of the athlete when faced with heavy straight weight.
4. AR adds intensity to training without applying more weight, giving the CNS a break from heavier lifting without decreasing intensity.
