Summary

Delayed onset muscle soreness is defined as the sensition of pain and discomfort in skeletal muscles that occurs after eccentric muscle actions or strenuous exercise like a marathon.

Detailed description

There is a growing body of clinical evidence which shows that noninvasive, nonpharmacologic pulsed electromagnetic fields have many clinical effects. Pulsed electromagnetic fields have shown to reduce pain in different groups of patients. This concerns patients with osteoarthritis, rheumatoid arthritis, diabetic neuropathy, fibromyalgia, distal radius fractures, pelvic pain and postoperative patients. A marathon is a muscular strain. Physiologic effects of a marathon involves muscular and connective tissue damage which initiates an inflammatory response as well as release of metabolic factors like lactate and free radicals, intracellular metabolites and by-products of proteolysis. The objective of this study was to investigate the efficacy of pulsed electromagnetic fields compared to placebo in reducing delayed onset muscle soreness in marathon runners.

Conditions

• Contracture of Muscle, Thigh

Interventions

Type	Name	Description
DEVICE	Pulsed electromagnetic field devices	Every person received two active devices. The devices emitted 2-ms bursts of 27.12 MHz sinusoidal waves repeating at 2 bursts/s. Peak magnetic field intensity was 0.05 G which induced an average electric field of 10 mV in the tissue with an effect of 7.3 mW/cm3.
DEVICE	Pulsed electromagnetic field devices	Every persons received two sham pulsed electromagnetic field devices.
