Who is an athlete?

A person who is coached and experienced in physical activities and sports is called an athlete.

Effect of increased body weight on the performance of an athlete
The performance of an athlete depends upon two major factors
• The health and fitness of an athlete
• The skill of an athlete
The health of the athlete an also dependent upon two factors, the structure and composition of the body of an athlete. As the lean body mass increase, the strength and power of the athlete also increase. Muscle strength is also dependent upon muscle size. A muscle used frequently energies hypertrophy i.e increases in size. On the other hand, if a muscle is not used over some time it undergoes atrophy(a decrease in muscle mass)for example in bedridden patients who don’t walk and exercise enough. Ab increase in exercise leads to an increase in muscle bulk, this boosting muscle power which contributes to increasing athletes’ speed.
The increased weight (for example due to fat deposition) of an athlete causes increased friction and the body has to do more work to move the body in the forward direction( for example in racing) and also while moving body in an upward direction in different athletic activities.

Effect of too much fat in the body

It is important to have a certain amount of fat in the body as it provides us energy in times of starvation or when the glucose level becomes too low to meet the body’s demand for energy. It also

provides insulation to our bodies. Women have a greater ratio of fat than men. But if in excess it not only affects the body’s metabolism and causes conditions for example hyperlipidemia and hypercholesterolemia but also affects the performance of athletes. Increased fat becomes a threat to the cardiovascular system as it causes atherosclerosis. Increased fat deposits in the abdomen (in

adipocytes) not only increases body mass(weight) but also hinder the athletic activities of a person.
Effect of amount of fat in different athletic activities
Different, athletic activities require different amounts of fat and lean body mass. Different sizes, stature and posture of athletes assist them to perform their different activities. An increase in body mass whether in the form of fat depletion helps athletes who require an increased muscle mass to perform their activities for example weight lifters, body builders and wrestlers etc.
On the other hand, a decrease in body fat leads to a Higher level of flexibility which helps them while competing in sports. Athletes for example runners and cyclists require low levels of body fat to decrease friction and show their maximum activity.

What is BMI? How it is measured?
What is Importance of BMI in an athlete’s life

BMI refers to body mass index. It’s measured by dividing a person’s weight (in kilograms) by the square of his height in meters. It tells about the presence of high levels of fats in the body. However, it does not tell about the exact amount of fat in a person’s body

Measurement of BMI
To measure a person’s BMI, weigh in kilograms. Then measure his or her height in meters and take a square of it. Divide them. Here’s your BMI.
What is the Importance of the Body mass index in the life of an athlete?
Depending on the conditions, a higher BMI can result in decreased athletic activities because it is usually the excess fat which leads to an increase in BMI. On the other hand, professional athletes usually have greater BMI due to their children increased body muscle mass.

How can an athlete improve his weight
It is dependent on two factors
Proper training
Proper training from a professional helps an athlete improve his body muscle mass.
Training enables the body to develop muscle mass over time, enhance skill, and increase motivation and self-assurance. Athletes can learn more about their activity through training, and they can also learn the value of maintaining a healthy body and mind.
You can achieve your sporting objectives quickly and effectively by using training that is tailored to your activity. It may improve performance, reduce the chance of injury, and lengthen your competitive career.
Proper diet and nutrition
Sports ability can be improved by proper nutrition. The majority of an athlete’s diet requirements should be covered by a well-planned, nutrient-rich diet, which also includes enough protein to support muscle development and repair. The diet should be built around foods high in unrefined carbs, such as wholegrain bread and cereals.
importance of height for the performance of an athlete
Height has a major impact on how well a person performs in sports. In many sports, taller athletes typically have an edge over shorter ones. Taller defensive linemen can use their extended arms to knock down passes, which is a distinct benefit for them.
In reality, it doesn’t matter as much as people believe. Tall people have more weight than shorter people even though they may have longer limbs thus reducing their efficacy. We can say that taller athletes with low body weight can be regarded as the ideal ones in athletic sports.
Factors affecting the height of an athlete  

These are
Nutrition of athlete
Children who are growing should eat a balanced diet that includes plenty of fruits, veggies, vitamins, and minerals to help them reach their full height potential. Protein and calcium are both crucial nutrients for kids’ meals.
Sleep of athlete
Sleep also affects the height of children especially. It has been found that the release of growth hormones increases during sleep which helps increase their growth. So children should not be deprived d of sleep as it will lead to a shortage of height.
Athletes are already involved in physical activities which helps in increasing their height. Supplements should also be given which tend to increase bine length and density. It will lead to an increase in height.
From this discussion, we have concluded that both height and weight of an athlete play an important role in his sports activities. Let’s not underestimate the importance of skill and practice which make pros in their fields.
