CHIROPRACTIC CARE MAY BOOST STRENGTH, MUSCLE FUNCTION, AND PREVENT FATIGUE
New research into the effects of chiropractic care suggests that it may have an important role to play in maximising sporting performance and aid recovery from a range of conditions where muscle function has been compromised. The New Zealand College of Chiropractic’s Centre for Chiropractic Research has recently published a study in the journal Experimental Brain Research1 which demonstrates that following a full spine chiropractic adjustment session there was an increase in the subjects’ ability to contract one of their leg muscles. The study shows an increase in muscle electrical activity readings of almost 60% and a 16% increase in absolute force measures. There was also a 45% increase in the ‘drive’ from the brain to the muscle (the degree to which the brain can activate that particular muscle) and a small, but significant, shift in the H reflex curve (a neurophysiological measure of spinal cord excitability). Dr Heidi Haavik, chiropractor and Director of Research a...
