概括
运动强度和体积的影响延迟发作的肌肉疼痛 (DOMS) 和疼痛感知. 然而,运动后的皮肤温度变化在不同强度或体积之间没有显著差异,这表明个人因素更有影响力.
科学领域:
- 运动生理学 运动生理学
- 运动科学 运动科学 运动科学
- 肌肉生理学 肌肉生理学
背景情况:
- 延迟发作的肌肉疼痛 (DOMS) 是强度炼的常见结果.
- 运动诱导的DOMS与皮肤温度等生理反应之间的关系尚未完全理解.
- 以前的研究还没有清楚地定义不同强度和体积的运动如何影响DOMS和相关的皮肤温度变化.
研究的目的:
- 调查不同的运动强度和体积是否会在健康成年人中引起不同的DOMS和皮肤温度反应.
- 为了比较三个运动方案 (疲劳,疲劳,次最大) 对DOMS,压力疼痛值 (PPT) 和皮肤温度 (IRT) 的影响.
主要方法:
- 39名健康的成年人被随机分为三组,运动强度和体积各不相同,目标是双臂肌.
- 使用数值疼痛率尺度 (NPRS),PPT测量和红外热学 (IRT) 在基线和运动后48小时测量了DOMS,PPT和皮肤温度.
- 进行了统计分析,以比较不同运动组的结果.
主要成果:
- 所有的运动方案都在运动后48小时诱导了DOMS和减少了PPT,在不同组之间观察到差异.
- 皮肤温度测量在炼方案之间没有显著差异.
- 在运动强度较高的群体中,在运动后48小时观察到最低皮肤温度的升高,但这种情况在炼和不炼的手臂中都观察到.
- 疼痛感知取决于运动强度,与PPT结果不同.
- 皮肤温度测量没有反映急性炼适应.
结论:
- 运动强度和体量显著影响DOMS和疼痛感知,但不影响皮肤温度反应.
- 运动后的皮肤温度变化似乎更多地受到个体参与者特征的影响,而不是运动强度或体积.
- 在这种情况下,IRT可能不是急性运动适应或DOMS严重性的可靠指标.

Exercise and Cardiovascular Response
734
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...

Assessing Body Temperature - Axilla
575
Procedural Guide for Assessing Axillary Body Temperature using a Digital Thermometer:
Step 1: Perform hand hygiene and put on clean gloves to maintain infection control and prevent cross-contamination.
Step 2: Prepare the patient by explaining the procedure to ensure understanding and cooperation. Ensure privacy, expose the axilla, and inform the patient that minimal movement is crucial for an accurate reading.
Step 3: Adjust the patient’s clothing to expose only the axilla. It minimizes...

Increased Body Temperature
642
A body temperature above 38°C (100.4 °F) is known as fever or pyrexia, and a person with fever is termed 'febrile.' Typically, the hypothalamus, a part of the brain that acts as the body's thermostat, regulates body temperature through a thermoregulatory setpoint. It receives signals from cold and warm thermal receptors throughout the body and adjusts the body's temperature accordingly. Fever occurs when this hypothalamic setpoint is altered, usually in...

Body Temperature
247
Body temperature reflects the equilibrium between heat production and heat loss within the body. Most heat is generated by metabolically active tissues, particularly the liver, heart, brain, kidneys, and endocrine organs. At rest, skeletal muscles contribute 20–30% of total heat production, but during vigorous exercise, this can increase up to 30–40 times.
The average body temperature is approximately 37°C (98.6°F) and typically ranges from 36.1–37.2°C...
