Read the following statement and select the correct optionStatement 1:...
Carbohydrates form the major fuel in the cells to provide energy for life processes. Carbohydrates form a better fuel than fats and proteins because their molecules have relatively more oxygen and therefore as compared to proteins and fats, they need less oxygen for their oxidation. Therefore, athletes, labourers doing heavy work and mountaineers should live on high carbohydrate diets.

Read the following statement and select the correct optionStatement 1:...
Statement 1: Athletes, labourers doing heavy work, and mountaineers should live on high-carbohydrate diets.
Statement 2: Carbohydrates need less respiratory oxygen for their oxidation than other foods.
Explanation:
Carbohydrates and Exercise Performance:
Carbohydrates are the primary source of energy for our body, especially during physical activities. They are broken down into glucose, which is then used as fuel for various bodily functions, including muscle contraction. For athletes, labourers doing heavy work, and mountaineers, who engage in strenuous activities, consuming a high-carbohydrate diet is crucial to meet their energy requirements. Carbohydrates provide a readily available source of glucose, ensuring optimal performance and preventing fatigue.
Carbohydrate Oxidation and Respiratory Oxygen:
The process of oxidizing carbohydrates in the body requires the consumption of oxygen. During exercise, our muscles require more oxygen to generate energy. However, compared to other macronutrients like fats and proteins, carbohydrates require less respiratory oxygen for their oxidation. This is because carbohydrates are already in a more oxidized state compared to fats and proteins. Therefore, the oxidation of carbohydrates is more efficient in terms of oxygen utilization.
Explanation of the Statements:
Statement 1 suggests that athletes, labourers doing heavy work, and mountaineers should consume high-carbohydrate diets. This is because carbohydrates provide a quick and efficient source of energy during physical activities.
Statement 2 explains the reason behind the recommendation in Statement 1. It states that carbohydrates need less respiratory oxygen for their oxidation compared to other foods, making them a suitable energy source during strenuous activities.
Conclusion:
Both Statement 1 and Statement 2 are correct, and Statement 2 provides a valid explanation for Statement 1. Athletes, labourers doing heavy work, and mountaineers should follow high-carbohydrate diets to ensure optimal energy levels and performance. The efficient oxidation of carbohydrates, requiring less respiratory oxygen, makes them an ideal choice for fueling intense physical activities.
