Cardiovascular exercise as it applies to Rugby players is activity involving the large muscles, such as your legs. The word 'aerobic' refers to something that needs oxygen. During cardiovascular or aerobic use oxygen gets continuously delivered to your muscles.
Players need huge amounts of muscular activity in any game. Forwards use greater amounts compared to backs because when a game stops for a scrum for instance backs line up to attack/defend and basically stand more of less motionless whilst forwards keep moving in the scum by pushing, this of course uses the larger muscles so requires more oxygen than the back at that time.

Cardiorespiratory endurance is the ability of the cardiorespiratory system to supply nutrients and oxygen to the body during sustained physical activity without fatigue. Endurance is a factor used to measure physical fitness. Cardiorespiratory fitness is the ability of the heart and lungs to function efficiently and effectively.
