What are the four types of sports in physical education?

There isn't a universally agreed-upon set of only four types of sports in physical education. The categorization varies depending on the curriculum and educational level. However, a common way to broadly group sports in PE would be based on the activities involved:

1. Individual Sports: These involve competition against oneself or others individually, such as track and field, swimming, tennis, or gymnastics.

2. Dual Sports: These involve competition between two individuals or teams of two, such as badminton, table tennis, or doubles tennis.

3. Team Sports: These involve competition between teams of multiple players, such as basketball, soccer, volleyball, or hockey.

4. Combative Sports/Martial Arts: These involve competition that incorporates fighting or grappling techniques, such as boxing, wrestling, judo, or karate.

It's important to note that other categorizations exist (e.g., based on equipment used, skill level required, or even the physical environment). The four categories above are a reasonable *general* grouping, but not an absolute or exhaustive classification.
