Question

When a person perspires (sweats), the body loses many sodium ions and potassium ions. The evaporation of sweat cools the skin. After a strenuous workout, people often quench their thirst with sports drinks that contain NaCl and KCl. A single 250. -gram serving of one sports drink contains 0. 055 gram of sodium ions

Answer 1

People reach for sports drinks after a strenuous workout because they help replenish lost sodium ions, aiding in the body's recovery and maintaining electrolyte balance.

Step-by-step explanation:

After intense physical activity, the body loses sodium ions through perspiration. Sodium is a crucial electrolyte for various bodily functions, including maintaining fluid balance and supporting nerve and muscle function. When individuals consume sports drinks containing NaCl (sodium chloride), they are effectively replenishing the lost sodium ions, helping restore electrolyte balance.

The sodium content in the sports drink is quantified as 0.055 grams per 250-gram serving. To understand its significance, we can calculate the approximate amount of sodium replenished per serving. The concentration of sodium ions is given by the formula:

`\[ \text{Concentration (g/mL)} = \frac{\text{Amount of Sodium (g)}}{\text{Volume of Solution (mL)}} \]`

Assuming the sports drink is a liquid and using the given values, we can find the concentration. This concentration represents the amount of sodium ions available to replenish the lost electrolytes. Consuming such a drink helps individuals recover more effectively after strenuous exercise by restoring the necessary sodium levels.

In summary, the inclusion of sodium in sports drinks serves a vital role in post-workout recovery by replenishing lost electrolytes. The quantified amount, such as the 0.055 grams per 250-gram serving mentioned, provides a tangible measure of the support these drinks offer to individuals engaged in rigorous physical activities.

Answer 2

Electrolytes are essential for body functions and are lost through sweat. Sports drinks replenish these, especially with sodium and potassium, to help maintain water balance and prevent electrolyte deficiency symptoms.

Step-by-step explanation:

Electrolytes such as sodium, potassium, and calcium are essential for various physiological functions, including nerve impulse conduction, muscle contractions, and maintaining water balance. When we sweat during activities like exercising, we lose these important ions.

Sports drinks are often formulated with these ions, especially sodium ions (Na+) and potassium ions (K+), to help replenish what the body has lost and maintain electrolyte balance.

For instance, the American College of Sports Medicine recommends that a sports drink should contain 125 milligrams of sodium per 8 ounces, as it helps in replenishing sodium lost in sweat.

During perspiration, not only is water excreted but also vital electrolytes, primarily sodium (Na+) and chloride (Cl-), along with potassium (K+), calcium (Ca+2), and magnesium (Mg+2).

To mitigate the loss of these electrolytes, particularly after strenuous workouts, consuming sports drinks can be beneficial to quickly restore these electrolytes in the body and prevent symptoms of deficiency such as nausea, fatigue, and dizziness.

Moreover, a well-maintained electrolyte level is crucial for preventing muscle weakness and severe health issues like increased heart rate leading to heart attacks.
