Carbohydrates are not fattening. Carbohydrates are the most preferred source of fuel for exercise. A carbohydrate-rich snack would help the child kick-start the training and also sustain energy levels. Ensure your child develops the habit of sipping of water regularly throughout the day. Proteins are vital for boosting post-training recovery as well as muscle-and-bone strength. Ensure all the major meals contain a source of good-quality protein — milk, dairy products, eggs, meat, chicken and fish. Pulses, legumes, nuts, oilseeds and varieties of peas are also good sources of plant protein. Eggs or milk can be used as a quickly absorbable source of protein in the post-training snack to support recovery.
