Impacts of Aging and Cardiorespiratory fitness
Aging normally refers to the physiological changes occurring in the human body with respect to time. Few of those changes involve the decline of some biological functions which leads to some adverse conditions to overall body functions. The reason for those changes includes past experiences, diet plans and focus on fitness, etc.
Identifying those changes is quite crucial in an aging person as they can get worsened over time. This is where the cardiorespiratory fitness level comes into use. It is an objective indicator of physical activity and can be used to assess the connection between physical activity and health status.
Here we are about to shed light on how people become unable to control their cardiorespiratory fitness levels as they age. So, let’s dig deeper.
What is cardiorespiratory fitness?
Cardiorespiratory fitness relates to physical fitness that relates to the ability of the circulatory and respiratory systems to supply oxygen during physical activities. It is determined by several non-changeable factors like age, gender, and some genetic factors.
On the other hand, it is strongly associated with several health outcomes which also include cardiovascular diseases. Thus, by using the cardiorespiratory fitness levels, you can determine how efficiently your system functions. So, it is basically an indicator determining how fit and healthy a person is.
How aging affects the respiratory system?
A number of changes occur due to aging in which few includes Loss of elasticity, reduction of vital capacity, impairment in O2 diffusion and reduction of respiratory efficiency, etc. Aging also reduces the sensitivity and working of the self-cleansing mechanism due to the degeneration of mucous glands and epithelium.
How aging affects the cardiovascular system?
The circulatory system comes first when it is about drastic changes in the human body while aging. When it is about the cardio vascular system, loss of elasticity in the Aorta and degeneration of cusps of heart valves goes through rapid changes. Aging also leads to myocardial changes increasing Atheroma incidence, and thus cigarettes and hypertension, etc.
Experiencing the changes physically takes some time depending on various factors. But, one can come across some symptoms like increased fatigue, indigestion, and minor problems in breathing. One may also come across decreased exercise tolerance and tiredness over time due to loss of elasticity of lungs.
There are lots of ways to increase cardiorespiratory endurance which can improve oxygen uptake in the lungs as well as heart. A few of those methods being able to increase endurance includes
- High-intensity sports
- Power walking
- Breathing exercises etc
All these activities are meant to prolong the physiological changes and to keep the system working for a long time. Resistance training and high-intensity workouts also come under those methods using which one can improve cardiorespiratory endurance.
Besides increasing endurance, regular workouts are also helpful in building muscle and burning calories. A balanced fat percentage in the body reduces the risk of drastic changes in the cardio vascular system and thus helps in sustaining the aging process.
