About this time last year I posted an article on weight gain during the winter months. Our bodies are designed to gain weight in the winter. It is how we keep warm. My suggestion was, and still is, that if we are going to gain weight anyways, let’s make it muscle.
In addition to eating enough calories to put on a pound or two (or five) of muscle (a pound is 3500 calories; and yes, we need to eat more to gain muscle weight), we also need to lift smarter. Two ways to gain muscle without having to lift a lot heavier are accommodated resistance and eccentrics (also known as negatives).
Accommodated resistance uses the bands, chains or weight releasers in combination with free weights. This allows for increased resistance at the end of the exercise where the muscles are strongest without compromising joints and other soft tissue at the beginning of the repetition where the muscles are at their weakest. Imagine using a large rubber band attached to the weight. The band stretches as the exercises is performed, so that at the top of the motion, the band provides the greatest amount of resistance. You can use lighter weights to overcome any sticking point or plateau that you may have.
It has also been shown that not only can one increase overall strength, but peak power, peak force, and peak velocity can also be improved using lighter loads which will transfer to almost any recreational or sporting activity (McBride et al 2002, and Wallace et al. 2006).
Eccentric training (aka negatives) provides resistance as the muscle fibers are trying to pull apart; the muscle is lengthening due to the weight being used against it while trying to contract due to controlling of the weight. This length-tension relationship disrupts the muscle fibers causing the other fibers in line (within the muscle) to increase the compliance to complete a contraction, which in turn causes another change in the length tension relationship - making a longer muscle fiber. Another thing that happens is that the long term effect of exercise increases the number of sarcomeres (a sarcomere is the functional unit of a muscle fiber where the contraction actually occurs) in a series, also increasing the muscle length and girth (Broccket et al. 2000, pp. 783 & 788).
Both eccentric muscle training and accommodated resistance training can increase strength, power, velocity, and force all while using lighter weight amounts. What a great way to beat the winter pounds.
