Epstein shares a demonstration comparing 1936 sprinter Jesse Owens to current sprinter Usain Bolt, so the role of biomechanics is to assess inertia overcoming, acceleration phase and deceleration phase. To understand more about the subject, we must know this. ....

<h3>Overcome inertia</h3>

The greater the athlete's mass, the greater his inertia. That's why strong muscles to generate explosive force capable of overcoming inertia. Reaction Time (RT) – reaction time to the stimulus (sound) at the start

<h3>The acceleration phase</h3>

It is no use for an athlete to accelerate a lot (maximization) because he will have difficulties in the deceleration (maximized) phase.

Each athlete and their coach have to identify their optimal acceleration, because only then you will also get a great deceleration.

<h3>Why does everyone slow down?</h3>

They cannot generate driving forces greater than the dissipative forces, this determines the decrease in speed in the final 2/3 of the race.

The kinetic energy of the sprinters at the moments of finals of the test is lower.

TEC – Kinetic Energy Theorem:

Ec = FR

With this information, we can conclude that all runners use biomechanics to assess the overcoming of inertia, acceleration phase and deceleration phase.

Jackson, age 65, comes to the doctors office complaining of a sharp pain in the right side of his chest. he says his chest hurts

valkas [14]

The answer 1: The pleurisy

Pleurisy corresponds to the presence of liquid between the two sheets of the pleura, the membrane lining the thoracic cavity and having for goal the protection of the lungs. We speak of purulent pleurisy when the fluid contained in this pleural cavity consists of pus.

Answer 2: Pulmonary auscultation

In healthy subjects, pulmonary auscultation can be used to hear normal breathing sounds called vesicular murmur. It results from the movement of air in the tracheobronchial tree and alveoli. He is gentle, breathing in inspiration; it is more intense but shorter in expiration. There may be variations in vesicular murmur intensity as a function of chest wall thickness (eg decreased vesicular murmur in obese subjects).

In the pathological state, several abnormalities can be found at auscultation:

Inversion of the respiratory rhythm with prolongation of expiratory time (emphysema and asthma)

Changes in the vesicular murmur:

Added noises like rales, and pleural friction.

Answer 3:

The auscultation of the lungs will find suspicious signs, showing the presence of fluid in the pleura: sounds heard on normal auscultation are reduced or inexistent, and it is only in one lung generally. The confirmation is simple enough to perform via a chest x-ray showing the presence of fluid in the pleura.

Besides that, the doctor will look at the location of the pain, and he will look for breathlessness too.
