Chapter 2 of NCERT Class 10 Physical Education is titled Effects of Physical Activities on Human Body. This chapter talks about how regular exercise and physical activities affect different systems of the body such as the circulatory, respiratory, muscular, and skeletal systems. It also explains the short-term and long-term benefits of physical fitness and how daily movement supports overall health. The aim is to help students understand the scientific basis of physical training and how it impacts their growth and development.
I chose to write on this topic because many students engage in physical activity but are unaware of the actual effects it has on their body. Knowing how exercise improves heart function, strengthens muscles, boosts lung capacity, and even supports the bones can motivate students to be consistent with their physical routines. Understanding these benefits also helps during school fitness tests or when preparing for sports competitions. For students, this chapter is not just about theory—it can be applied directly in daily life.

Effects of Physical Activities on Human Body
Circulatory System
Regular exercise strengthens the heart and improves blood circulation. It increases the efficiency of the heart muscles, lowers resting heart rate, and helps maintain healthy blood pressure.
Respiratory System
Physical activities improve lung capacity and efficiency. When you run or cycle, your breathing becomes deeper and faster, which increases oxygen intake and carbon dioxide removal.
Muscular System
Physical movement increases muscle strength, flexibility, and endurance. Activities like push-ups, stretching, and resistance training help in building strong and toned muscles.
Skeletal System
Bones become stronger with weight-bearing activities such as walking, running, and jumping. Regular physical activity helps in maintaining bone density and reduces the risk of osteoporosis later in life.
Physical Activity and Growth
Children and teenagers who are physically active tend to grow stronger and healthier. Exercise promotes healthy hormonal balance, better posture, and helps prevent lifestyle diseases.
Other Benefits of Regular Exercise
- Improves digestion and metabolism
- Enhances mental focus and mood
- Boosts immunity
- Helps in weight management
