Here you have an executive summary of a very interesting paper written by Dr G.L. Khanna & Dr I. Manna about the benefits of taking an Isotonic drink to improve sports performance.

Background & objectives: Carbohydrate-electrolyte drink has a significant role on energy balance
during exercise. The present study was designed to investigate the effect of oral carbohydrateelectrolyte
supplementation on sports performance and cardiovascular status of the national
level male athletes during exercise and recovery.

Results: Significant improvements were noted in total endurance time, heart rate responses and
blood lactate during exercise at 70 per cent VO2max after the supplementation of 5 g per cent
carbohydrate-electrolyte drink. However, no significant changes were noted in blood glucose
and peak lactate level irrespective of supplementation of carbohydrate-electrolyte drink.
Significant improvement in cardiovascular responses, blood glucose and lactate removal were
noted during recovery following a 12.5 g per cent carbohydrate-electrolyte drink.

Interpretation & conclusion: Carbohydrate-electrolyte drink can increase endurance performance
as well as enhance lactate removal and thereby delaying the onset of fatigue.
