Skin temperature in youth soccer players with functional equinus and non‐equinus condition after running.

Objectives: To check how a thermal IR camera can check skin temperature in gastrocnemius‐soleus equinus condition and non‐gastrocnemius‐soleus condition in youth soccer players and thus detect association between the extensibility of the triceps surae (with gastrocnemius‐soleus equinus and non‐gastrocnemius‐soleus equinus) and the muscle temperature pattern. Design: A cross‐sectional study secondary level of care. Methods: Sample from an elite soccer academy in Madrid (Spain) 35 healthy male subjects (youth soccer players) age 12.82 ± 1.07 years, height 158.68 ± 10.79 cm, weight 49.19 ± 9.45 kg, body mass index 19.41 ± 2.25. The exclusion criteria were the presence of musculoskeletal and joint injuries, pelvic pain, ankle sprains, low back pain and use of drugs in the previous week, and scoliosis. Results: Temperature value for gastrocnemius muscles and Achilles tendon were assessed in 35 youth soccer players from an academia before and after training in both 12 gastrocnemius‐soleus equinus and 23 non‐gastrocnemius‐soleus equinus soccer players conditions. State absolute for gastrocnemius soleus condition obtained a 0.34 value (0.19–0.5); we found a significant increase in temperature among these conditions for the gastrocnemius (P = 0.028) and the Achilles tendon (P = 0.007) (confidence interval 95%). The temperature of gastrocnemius‐soleus equinus for gastrocnemius and Achilles tendon was increased more than non‐gastrocnemius‐soleus equinus in youth soccer players. Conclusions: IR imaging captured temperature is associated with muscle pattern activation for lower limb. Based on our findings, we propose that infrared thermography evaluation of the gastrocnemius and Achilles tendon is suitable to differ gastrocnemius‐soleus equinus and non‐gastrocnemius‐soleus equinus conditions in youth soccer players.
