“…This technology gauges the correlation between muscle activation and skin temperature, as muscle and skin temperature are directly correlated. The information this technology provided is based on the hyperthermic and hypothermic responses of the skin [ 20 ], due to the fact that thermography is a reliable method to assess skin temperature [ 21 ]. Moreover, athletes are presumed to keep their thermal pattern constant in baseline conditions, and thermal asymmetries in the bilateral body areas (e.g., ankle, knee, hamstring or elbow) are linked to factors related to injuries, such as inflammation or secondary trauma, as in normal conditions, the temperature of both sides of the bilateral areas should increase equally [ 22 ].…”

Football is a very demanding sport which requires players to exert maximum effort, producing fatigue and eventually injuries. Thermography can be used to detect fatigue and prevent its consequences through thermal asymmetries in the bilateral body areas; however, its adequacy for elite footballers has not been widely studied. Therefore, the objective of the present investigation was to determine the suitability of thermography to detect fatigue in male football players. For this reason, twenty participants were gathered into a pair of subgroups (low [<0.2 °C] vs. high thermal asymmetry [≥0.2 °C]) based on a thermography session of the lower limbs (thighs, calves, and hamstrings). After the thermography session, players performed CMJs before and after an RSA test (6 × 30 m/20″). A mixed two-way analysis of variance and Bonferroni post hoc pairwise comparisons were undertaken to analyse the results. No significant differences (p > 0.05) were found in any of the RSA test variables between low and high thermal asymmetry groups for thighs and calves. On the other hand, the low thermal asymmetry hamstring group reported a smaller percentage difference in sprints for the first sprint (%Diff) and a larger percentage difference in sprints two and three with respect to the best sprint (%Best). For CMJs, the low thermal asymmetry hamstring group reported significantly higher values post-RSA test, indicating better performance. Accordingly, thermography can provide information about performance in CMJ and RSA tests through hamstring asymmetries over 0.2 °C. Meanwhile, larger asymmetries than 0.2 °C in calves and thighs do not seem to be related to performance in these tests; therefore, coaches should consider if it is optimal to align players with high hamstring asymmetries.

“…La prueba ejecutada por Shimazaki & Murata (2015) tenía una mayor duración e intensidad. En esta misma línea, puede que la escasa duración de la prueba repercutiera en la falta de diferencias entre condiciones, ya que se necesitan 20 minutos para que aparezcan las variaciones térmicas a nivel corporal y este tiempo puede ser mayor en las zonas periféricas como son los pies (Charkoudian, 2003;Fernández-Cuevas, 2012).…”

Actualmente, están disponibles en el mercado nuevos modelos de calzado deportivo, como el calzado inestable. Sin embargo, todavía existe una falta de evidencia respecto a los cambios que este tipo de calzado puede producir en la biomecánica de la marcha. Así pues, el objetivo de esta investigación fue analizar los efectos agudos del calzado inestable sobre los impactos de aceleración, así como también sobre la variación de temperatura superficial plantar. Seis deportistas (estudiantes físicamente activos, edad 28±8 años, altura 1.73±0.05 m, masa corporal 68.7±6.7 kg, talla de pie 41±1.6 cm) participaron voluntariamente en el estudio. Las características de la pisada se obtuvieron mediante el test Foot Posture Index. La prueba de marcha se llevó a cabo sobre tapiz rodante (10 minutos a 1.44 m/s) bajo dos condiciones de calzado: zapatillas estables y zapatillas inestables. Se analizaron los impactos de aceleración (en tibia y cabeza), y la temperatura superficial plantar (en antepié, mediopié y retropié) en diferentes momentos de la prueba. Los resultados no mostraron diferencias significativas entre ambos tipos de zapatillas en las variables de acelerometría analizadas en ninguno de los momentos de registro. Sin embargo, sí se encontraron diferencias significativas entre ambos calzados (estable=1.40ºC, inestable=3.10ºC, p=0.004) en la variación de temperatura plantar del mediopié en ΔTPost5 (diferencia entre antes del inicio de la prueba y 5 minutos después de finalizarla). En conclusión, las zapatillas inestables parecen no producir ningún beneficio adicional al calzado tradicional para el deportista durante la marcha. Palabras clave: zapatillas, marcha, biomecánica, acelerometría, termografía. Abstract. Nowadays, new models of sports footwear are available on the market, such as unstable shoes. However, there is still a lack of evidence regarding the changes that this type of footwear can produce on gait biomechanics. Therefore, the aim of this research was to analyze the acute effects of unstable shoes on acceleration impacts, as well as on plantar surface temperature variation. Six athletes (physically active college students, age 28±8 years, height 1.73±0.05 m, body mass 68.7±6.7 kg, shoe size 41±1.6 cm) voluntarily participated in the study. Gait characteristics were obtained by means of the Foot Posture Index test. The walking test was performed on a treadmill (10 minutes at 1.44 m/s) under two footwear conditions: stable shoes and unstable shoes. Acceleration impacts (tibia and head), and plantar surface temperature (forefoot, midfoot and rearfoot) were analysed at different moments during the test. The results showed no significant differences between the two types of shoes in the accelerometry variables analyzed at any of the recording times. However, significant differences were found between both shoes (stable=1.40ºC, unstable=3.10ºC, p=0.004) in the variation of midfoot plantar temperature at ΔTPost5 (difference between before the start of the test and 5 minutes after the end of the test). In conclusion, unstable shoes do not seem to produce any additional benefit to traditional shoes for the athlete during walking. Keywords: sport shoes, gait, biomechanics, accelerometry, thermography.
