Question

it is important to drink plenty of water before and during a heavy workout because keeping hydrated

prevents you from perspiring

causes an electrolyte imbalance

prevents an electrolyte imbalance

helps you perspire more

which contributes to obesity? *

avoiding fast food

a balance of high - fat and low - fat foods in the diet

having an excess of muscle

a sedentary lifestyle

Explanation:

For the first question: Hydration supports normal bodily functions during exercise. Perspiration is a natural cooling mechanism, and proper hydration maintains electrolyte balance (dehydration causes imbalance, not hydration). Hydration doesn't prevent perspiration or make you perspire excessively, but it supports normal perspiration and prevents electrolyte imbalance.
For the second question: Obesity is linked to calorie imbalance and low physical activity. Avoiding fast food, balanced fat intake, and excess muscle (which burns more calories) do not cause obesity. A sedentary lifestyle (little physical activity) leads to reduced calorie burn, contributing to weight gain and obesity.

Answer:

1. prevents an electrolyte imbalance
2. a sedentary lifestyle
