与年轻的成年人相比,老年马在结构化装扮训练期间表现出自主调节的减少. 精心管理身体活动对于老年马的福利至关重要.
科学领域:
- 马类生理学 马类生理学
- 动物福利科学动物福利科学
- 兽医运动医学 兽医运动医学
背景情况:
- 马的生理能力在15岁以后通常会下降.
- 一些老年马继续要求体育职业,引发了福利问题.
- 需要客观的自主调节措施来评估老年马在运动期间的福利.
研究的目的:
- 为了比较不同训练方案下的老年和成年马的休息心率 (HR) 和心率变化率 (HRV).
- 评估结构化装扮训练与学校骑行对马匹自主调节的影响.
- 在从事体育活动的老年马中识别潜在的福利指标.
主要方法:
- 46匹马被分为成年 (<15岁) 和老年 (15-20岁) 组.
- 马匹参加了结构化装扮训练 (AL-1) 或骑行学校 (AL-2) 的30分钟时间段.
- 休息心率 (HR) 和心率变化 (HRV) 度量 (pNN50,SDANN,SDNNI,DC,SD2) 被记录和分析.
主要成果:
- 与AL-2相比,AL-1中的成年马表现出HR降低和RR间隔增加.
- 成年马在AL-1期间呈现出HRV (pNN50) 的增加.
- 老年马在AL-1期间显示HRV (SDANN,SDNNI,DC,SD2) 降低,与AL-2相比.
结论:
- 与老年马相比,成年马在结构化装扮训练中表现出优越的自主调节.
- 老年马在类似的训练条件下可能会出现自主功能受损.
- 调查结果强调了需要量身定制的体育活动管理,以确保老年马运动员的福利.

Factors Influencing Heart Rate
Let us explore the significant factors affecting heart rate, including age, body temperature, posture, acute pain, chemical influences,...
Cardiac Output I:Effect of Heart Rate on Cardiac Output
Cardiac output (CO) refers to the total amount of blood ejected by one of the ventricles in liters per minute (L/min). In a resting adult, CO ranges from 5 to 6 L/min, adjusting according to the body's metabolic requirements.
Effect of Heart Rate on Cardiac Output
Cardiac output adapts to metabolic demands during stress, physical activity, or illness. The autonomic nervous system regulates heart rate via the sinoatrial node. The parasympathetic nervous system decreases heart...
Exercise and Cardiac Output
Sustained exercise increases the muscles' oxygen demand, which can be...
Regulation of Heart Rates
The SNS increases heart rate through the release of norepinephrine and epinephrine, which act on beta-1 adrenergic receptors in the heart. This action increases the rate of depolarization in the sinoatrial (SA) node, the heart's...
Exercise and Cardiovascular Response
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...
