Resumen
El dispositivo portátil CORE sobreestimó la temperatura corporal central (TC) durante el ejercicio en calor. El grosor de la grasa subcutánea influyó en la precisión del dispositivo, lo que sugiere un sesgo potencial en las estimaciones de TC.
Área de la Ciencia:
- Fisiología del ejercicio
- Ingeniería biomédica
- Salud del medio ambiente
Sus antecedentes:
- El monitoreo preciso de la temperatura corporal central (TC) es crucial para prevenir enfermedades relacionadas con el calor durante la actividad física en condiciones de calor.
- La tecnología portátil ofrece un enfoque no invasivo para estimar TC, pero su validez requiere una investigación exhaustiva.
Objetivo del estudio:
- Para evaluar la validez del sensor portátil CORE para estimar la temperatura corporal central (TC) durante el ejercicio en un entorno caluroso.
- Investigar el papel del grosor de la grasa subcutánea en los posibles sesgos observados en las mediciones TC del sensor CORE.
Principales métodos:
- Veinticuatro participantes sanos (13 hombres, 11 mujeres) realizaron 60 minutos de ejercicio en bicicleta con el 60% de la potencia aeróbica máxima en un ambiente caliente (35,9°C).
- La temperatura corporal central (TC) y la temperatura de la piel (TSK) se midieron utilizando el sensor CORE y se compararon con las sondas rectales y de la superficie de la piel.
- Se midió el grosor de la grasa subcutánea en la línea midaxillar utilizando ultrasonografía para evaluar su correlación con el sesgo TC.
Principales resultados:
- El sensor CORE mostró una sobreestimación general no significativa de TC, pero la sobreestimó significativamente durante la segunda mitad del ejercicio.
- El dispositivo también sobreestimó significativamente la temperatura de la piel (TSK) durante todo el período de ejercicio.
- El espesor de la grasa subcutánea midaxillar se correlacionó positivamente con el sesgo de sobreestimación de TC durante el tercer y cuarto trimestres de ejercicio.
Conclusiones:
- El sensor CORE demostró una sobreestimación de la temperatura corporal central (TC) en comparación con las mediciones rectales durante el ejercicio sostenido en el calor.
- El aumento de la temperatura de la piel (TSK) y el grosor localizado de la grasa subcutánea parecen ser factores potenciales que contribuyen al sesgo en las estimaciones de TC del sensor CORE.

1.3K
Regular physical activity is essential for maintaining cardiovascular health, with aerobic exercises being particularly effective. According to the American Heart Association, 150 minutes of moderate to intense aerobic exercise per week is recommended for a healthy heart. Aerobic activities may include brisk walking, running, bicycling, cross-country skiing, and swimming, ideally performed three to five times per week.

Introduction
Exercise stress testing, commonly known as a treadmill test, is a noninvasive procedure used to evaluate cardiovascular function and diagnose heart conditions.
Definition
An exercise stress test measures the heart's response to exertion using a treadmill or stationary bicycle. Chest electrodes record the heart's electrical activity through an ECG, and blood pressure is monitored regularly.

1.2K
Body temperature can be assessed using various devices and measured in Celsius or Fahrenheit.
Glass-bulb Thermometer:
Glass-bulb thermometers are hollow glass tubes with a bulb tip containing liquid such as ethanol or mercury. Historically, glass bulb mercury thermometers were the standard device to measure body temperature. Today, mercury thermometers are prohibited in many countries due to the hazardous effects of mercury and the risk of exposure if the glass bulb breaks. In general,...

Exercise significantly impacts cardiovascular response, which is crucial for understanding patient health and designing effective treatment plans.
Light to moderate physical activity initiates a series of interconnected responses in the body. The heart rate modestly increases in anticipation of the workout, followed by widespread vasodilation as oxygen consumption by skeletal muscles increases. This results in decreased peripheral resistance, increased capillary blood flow, and accelerated...

2.6K
If the temperature of an object is changed while it is prevented from expanding or contracting, the object is subjected to stress. The stress is compressive if the object expands in the absence of constraint and tensile if it contracts. This stress resulting from temperature change is known as thermal stress. It can be quite large and can cause damage. To avoid this stress, engineers may design components so they can expand and contract freely. For instance, on highways, gaps are deliberately...
