Gcse Pe Paper 1 The effects of exercise

The video tutorial covers the short-term and long-term effects of exercise on the cardiovascular and muscular systems. Immediate effects include increased temperature, heart rate, and breathing depth. Short-term effects, occurring up to 36 hours post-exercise, include fatigue, DOMS, and cramp. Long-term effects from sustained training include changes in body composition, improved fitness components, and adaptations like muscular and cardiac hypertrophy. The tutorial also highlights the importance of understanding these effects for exams and invites viewers to a live revision session.

Which systems are primarily affected by exercise according to the introduction?

• Cardiovascular and skeletal systems
