Cardiorespiratory training focuses on improving the function of the cardiovascular and respiratory systems. This type of training results in a greater capacity for carrying oxygen throughout the body. This allows for more efficient delivery of oxygen and nutrients to working muscles, which can improve overall athletic performance and endurance. Option A is incorrect because in cardiorespiratory training, the delivery of oxygen and nutrients is actually increased. Option B is incorrect because cardiorespiratory training leads to an increase in aerobic production of ATP, which is the primary source of energy for the muscles. Option D is incorrect because cardiorespiratory training actually increases the number of blood vessels and capillaries, increasing the delivery of nutrients to the muscles.
