For years, Biofreeze® topical analgesics have provided pain relief for patients with musculoskeletal discomfort, including delayed onset muscle soreness (DOMS), which as we all know is muscle soreness experienced 24-48 hours after strenuous or unaccustomed exercise. DOMS is caused by inflammation that produces swelling within muscle cells (it’s not the lactic acid, folks!).
Researcher Michael Rogers PhD, CSCS, head of the kinesiology department at Wichita State University, wanted to know how long Biofreeze topical analgesic could reduce DOMS pain.
“DOMS is a common problem associated with resistance training,” said Rogers. “The pain and stiffness sometimes prevents an individual from doing their daily activities and may deter someone from continuing their workouts.”
Dr. Rogers and his colleagues induced DOMS of the thighs in nine college students using a high-intensity squat routine. 24 hours after the exercise, the subjects applied Biofreeze or a placebo gel to their quadriceps and rated their DOMS pain every 30 minutes for eight hours.
The subjects using Biofreeze experienced a 20% decrease in pain 60 minutes after application, which was significantly less pain than the placebo group. The pain levels remained significantly lower than the placebo for five hours. In conclusion, Biofreeze provides maximal pain relief from DOMS within one hour, and lasts up to five hours after application.

How Biofreeze Works
Whether it’s an overworked muscle, a chronically achy back or the discomfort of arthritis, pain affects millions of Americans every day. Biofreeze is a topical analgesic that uses the cooling effect of menthol, a natural pain reliever, to soothe minor muscle and joint pain. It penetrates quickly, offering relief through cold therapy. For this reason, it’s especially effective for use in conjunction with hands-on health care such as chiropractic, massage and physical therapies, and podiatry.
Biofreeze invests in scientific research in order to best understand how to help people relieve pain. The science behind Biofreeze is a dual approach to pain relief, based on the following theories.
The Gate Control Theory
As outlined in our next article, “The Science of Pain,” special receptors are responsible for sending pain signals to the brain by way of the spinal cord. When Biofreeze is applied to a painful area, it’s thought to create a cold sensation that overrides these pain signals.
Stimulation of Cold Receptors
When Biofreeze is applied, menthol binds with temperature-sensitive receptors in the skin. Activating these receptors is thought to modulate pain signals through the body’s natural pain-relieving systems. This mechanism works similarly to ice, but with additional benefits.
