まとめ
COREのウェアラブルデバイスは,熱中での運動中に体温 (TC) を過大評価した. 皮下脂肪の厚さは装置の精度に影響を与え,TCの推定に潜在的なバイアスを示唆しました.
科学分野:
- 運動 生理学
- 生物医学工学
- 環境 健康
背景:
- 熱い環境での身体活動中に熱に関連した病気を予防するには,正確な体温 (TC) 監視が不可欠です.
- ウェアラブル技術は TCを推定するための非侵襲的なアプローチを提供しますが,その有効性は徹底的な調査を必要とします.
研究 の 目的:
- 暑い環境での運動中に体温 (TC) を推定するためのCOREウェアラブルセンサの有効性を評価する.
- COREセンサーのTC測定で観察された潜在的なバイアスの皮膚下脂肪の厚さの役割を調査する.
主な方法:
- 24人の健康な参加者 (男性13人,女性11人) は,熱い環境 (35. 9°C) で最大有酸素力の60%で60分のサイクリング運動を行った.
- コア体温 (TC) と皮膚温度 (TSK) は,COREセンサーを使用して測定され,直腸と皮膚表面のプローブと比較されました.
- TCバイアスとの相関性を評価するために,超音波を用いてミダキラーラインの皮下脂肪の厚さを測定した.
主要な成果:
- COREセンサはTCの全体的な過大評価を示しましたが,運動の後半では大幅に過大評価しました.
- この装置は,運動期間中,皮膚の温度 (TSK) を著しく過大評価した.
- 運動の第3および第4四半期におけるTC過大評価バイアスと正の相関関係がある.
結論:
- COREセンサは,熱中での持続的な運動中の直腸測定と比較して,体温 (TC) の過大評価を示した.
- 皮膚の温度上昇 (TSK) と局所的な皮下脂肪の厚さは,COREセンサーのTC推定値のバイアスに寄与する潜在的な要因であるようです.

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...
