Vitamin D Status Is Not Associated with Outcomes of Experimentally-Induced Muscle Weakness and Pain in Young, Healthy Volunteers

Figure 3

Plot of mean pain intensity rating (scale 0–100) during unloaded movement through full range of motion of the elbow versus serum 25-hydroxyvitmamin D (25OHD) concentrations (nmol/L) in female participants (𝑁=21). Pain rating obtained 2 days after eccentric exercise protocol; 25OHD serum samples obtained within one week of exercise. Linear regression 𝑅-squared value = 0.07, 𝑃𝑣𝑎𝑙𝑢𝑒=.24. Plot, 𝑅-squared, and 𝑃 value are representative of other pain and muscle strength variables examined in both sexes.
