Chelsea and Marie are at the Olympics and watching the track and field events. They observe the landing of the shot-put with a big "thud," vaulters clearing the bar for the pole vault, runners starting their 26.2 mile marathon, and racers completing their final lap of the mile run. Analyze the events and determine which pair of events is considered anaerobic activities: Marathon and Pole Vault Marathon and Mile run Pole vault and Shot-put Shot-put and Mile run

The two events that are anaerobic activities are:

Pole vault and Shot-put.

Explanation:

a) Analysis of events:

Events         Type of activity

Marathon    aerobic

Pole Vault   anaerobic

Mile run      aerobic

Shot-put     anaerobic

b) Anaerobic activities like pole vault and shot-put involve quick bursts of energy in the absence of free oxygen. They are usually performed using maximum effort for a short period of time. Other examples include jumping, sprinting, or heavy weight lifting.  The aerobic activities like mile run and marathon do not require quick bursts of energy.  They require sustained efforts for some long time and in the presence of free oxygen.  The athlete's respiration and heart rate differ in aerobic activities versus anaerobic exercises.  During aerobic activities, oxygen remains the main energy source.
