This lesson is aimed at gaining pupils understanding of the effect that aerobic and muscular endurance exercise can have on their skill level. Pupils completed a number of skill games/test/tasks prior to taking part in a 10-20 minute bout of step aerobics. Immediately following the step aerobics the pupils completed the test/games/tasks again to see if their scores would differ. The premise behind the lesson was to look at a professional athlete and think about how difficult it is for them to keep their skill level up for a prolonged period of time.
