Resistance Training in the Rehabilitation of Lower Back Pain.

A recent Canadian study looked into different ways of rehabilitating lower back pain; Aerobic Training (AT) and Resistance Training (RT). They compared these two different training methods over a 16-week exercise program to those who continued with their life (control).



Both the RT and AT groups followed a periodised model of training over the 16 weeks, which consisted of varied intensity with differing volumes of work. The RT used a variety of modes of training, including machines, free weight and body weight exercises. The subjects performed 2-3 sets of between 8-15 reps of each exercise depending on the week.

Subjects in the AT group were to choose from the elliptical trainer and treadmill (walking or jogging). Duration for both the AT and RT were kept the same with the total amount per week varying between 60 minutes and 155 minutes. Intensity was gauged using the Borg scale for perceived rating of exertion and varied from 10 to 13. The researchers looked at a variety of fitness and health indices including strength, flexibility, aerobic capacity (VO2max) and body composition. They also assessed the overall quality of life, pain assessment and ability to perform ADL.

Compared to the control group the RT group showed a decrease of body fat, pain and disability as well as an increase in muscular strength, flexibility and quality of life.
