what is the relationship between height and vital capacity?

Results: Mean vital capacity in students with height > 167.4 cm was higher than average vital capacity of students with height ≤ 167.4 cm. It might be due to the increased surface area of the lungs in relation with increasing height.

We do know that identical twins can differ in height due to differences in the womb. About 60%-80% of height variation is due to genetic factors and 40%-20% is determined by environmental factors, mainly nutrition, leading to differences in stature, including foot size.

In general regular exercise does not substantially change measures of pulmonary function such as total lung capacity, the volume of air in the lungs after taking the largest breath possible (TLC), and forced vital capacity, the amount of air able to be blown out after taking the largest breath possible (FVC).

While lung capacity refers to the maximum amount of air that your lungs are able to hold, lung function refers to how quickly you can inhale and exhale air from your lungs and also how effectively your lungs both oxygenate and remove carbon dioxide from your blood.

Many people are dissatisfied with their heights and would like a simple and effective way, such as supplementation with a hormone like GH, to make themselves grow. While it is true that GH is associated with “building up” as its primary role in the body, there is absolutely no evidence that it makes adults taller.

LOG IN. June 14, 2001 -- Being tall may make it easier to score baskets and look good in certain clothes. But statistical analyses show that taller people, on average, also tend to live longer lives than shorter people.

Factors affecting changes in physiological measurements, e.g. illnesses and infections, stress, anxiety, lifestyle factors, medication, age, environment, time of day. Assessment, e.g. body functions and health status.

Height is largely determined by genetics, and most people will not grow taller after age 18. However, proper nutrition during childhood and adolescence can help you maximize your height.

Shorter men live longer, study shows. ... Short height and long life have a direct connection in Japanese men, according to new research. Shorter men are more likely to have a protective form of the longevity gene, FOXO3, leading to smaller body size during early development and a longer lifespan.

Tidal volume is the normal volume of air inhaled in one breath at rest. Total vital capacity is the maximum amount of air a person can expel from the lungs after a maximum inhalation. This usually occurs when a person is under physical stress.

"Perhaps when humans were in the early stages of organisation, they used height as an index for power in making 'fight or flight' decisions. They ascribed leader-like qualities to tall people because they thought they would be better able to protect them.

Inspiratory Capacity: The difference in inhaled volume between FRC and total lung capacity. Vital Capacity: The amount of gas inhaled from FRC to total lung capacity. Inspiratory Reserve Volume: The amount of gas inhaled from peak normal inspiratory volume to total lung capacity.

['Body size: Metabolic rate increases as weight, height, and surface area increase.', 'Body composition: Fat tissue has a lower metabolic activity than muscle tissue. ... ', 'Gender: The basal metabolic rate (BMR) averages 5 to 10 percent lower in women than in men.']

Not necessarily. Long babies may well grow up to be tall, but genes also have an influence. If you and your partner are tall, then your baby is also likely to be tall, even if he was a small baby.

Relationship between lung volume and PVR is "U"-shaped. Pulmonary vascular resistance is lowest at FRC. At low lung volumes, it increases due to the compression of larger vessels. At high lung volumes, it increases due to the compression of small vessels.

According to the latest CDC stats, these are the average heights for U.S. adult men based on age: Ages 20 to 39: 176.1 centimeters, or roughly 5 feet, 9 inches. Ages 40 to 59: 175.8 centimeters, or roughly 5 feet, 9 inches. Age 60 and older: 173.4 centimeters, or roughly 5 feet, 8 inches.

The vital capacity (VC) measures the maximum amount of air that can be inhaled or exhaled during a respiratory cycle. It is the sum of the expiratory reserve volume, tidal volume, and inspiratory reserve volume. ... The functional residual capacity (FRC) includes the expiratory reserve volume and the residual volume.
