This statement is true. Vigorous physical activity that raises the heart rate to the high end of the aerobic zone (usually around 70-85% of maximum heart rate) is considered to be more effective for improving fitness than medium intensity activity that only raises heart rate to the low end of the zone (usually around 50-65% of maximum heart rate). This is because the higher intensity activity provides a greater challenge to the cardiovascular system and stimulates greater physiological adaptations.
