True or false? Aerobic exercise increases the number of muscle fibers in a muscle.
aerobic respiration can leads to buildup of lactic acid in the muscle True False

Sometimes after an intense exercise routine, an individual will have sore muscles 1 to 2 days following the exercise; this is called delayed onset muscle soreness. Although not completely understood, it is believed that one cause of this is damage that occurs to the Z disks and contractile filaments in the muscles. When the body attempts to repair this damage, an inflammatory response occurs that causes soreness a couple of days after the exercise has taken place. Which of these situations would likely lead to less delayed onset muscle soreness in an individual? a. a mutation in the Z-disk protein that caused the attachment of the Z disk to the titin protein to be stronger b. a mutation that would reduce the amount of lactic acid buildup in muscle tissue c. a mutation in the Z-disk protein that caused the attachment of the Z disk to the titin protein to be weaker d. a mutation that weakens the calcium binding ability of troponin
