A beginning powerlifter, having heard about the research on aerobic endurance exercise as a prophylactic approach to preventing coronary artery disease, wants to add 30 minutes of running five days per week to his current program. What effect will this have on his powerlifting performance?

Aerobic endurance exercise has a lot of positive effect on a powerlifter. Let me mention some of the major positive effects ;

Aerobic endurance exercise helps the powerlifter build stronger bones, improve muscle strength. It also improves his endurance and flexibility, it improves the powerlifter's balance hence reducing the risk of falling

Research has shown that aerobic endurance exercise can improve ones mood and mental alertness.

Explanation:

The training performance will be drastically reduced, because of  specificity. This is because based on the principle of specificity,  the training pattern  a sport person must adopt to  ensure desire effect should be the type that   matched the specific sport the  person is training for or preparing for. Therefore in this scenario the weightlifter  performance will drop, because  the 30 minutes  of ruining for 5 days is not relevant  to the training pattern he needs for power lifting  for a desired effect.

Besides  the  introduction of the new training £0 minutes) pattern is now  phosphagen ( high intensity) which is not needed. This will affect muscle contraction leading to change in muscle fibres. It is therefore  advisable to continue with his oxidative  training and discard the  phosphagen 30 minutes of  training to maximum performance.
