Which option is correct about delayed onset muscle soreness (DOMS)?

• Caused by eccentric muscle contractions - Minimized by increasing the eccentric muscle contractions during early training

• Caused by concentric muscle contractions - Minimized by starting training at a low intensity and gradually increasing the intensity

• Caused by eccentric muscle contractions - Minimized by warming up before exercise

• Caused by concentric muscle contractions - Minimized by cooling down after exercise
