FACTORS AFFECTING HEART RATE=1.Hormones, age,fitness level, autonomic innervation.

FACTORS AFFECTING THE STROKE VOLUME= Heart size, gender,preload,afterload

AT REST= The woman have less cardiac output than males due to less body surface area.

AT EXERCISE=Cadiac output increases during exercises because of increase in heart rate and force of contraction,however it depends on force of severity of exercise.
