The solution with lower solute concentration is referred to as hypotonic solution while the other with higher solute concentration is called as hypertonic solution.
Since the solution concentration on inside of the cell is lower than that of solution present on the outside the cell; the solution inside the cell is hypotonic.
A change in the anthropometric index across the distribution (5-95 percentile) resulted in a decrease in the E/I ratio of 0.032-0.037 and a decrease in the HRMax-Min of 1.56-2.39 beats/min.
