The purpose of this investigation was to assess whether using an infra-red thermal camera is a valid tool for detecting and quantifying the muscle soreness after exercising.
The overall goal of this procedure is to identify and measure delayed onset muscle soreness or DOMS in its initial stages using a thermal infrared camera. The first step is to take baseline images of both arms. Pain measurements are done using a visual analog scale, and blood is drawn to measure serum myoglobin.
Next muscle strength is measured in the arm that will be exercised. The appropriate weight needed for the exercise is calculated as a percentage from this muscle strength measurement. Then the subject does four sets of 25 repetitions using the calculated weight.
