  • Cardiorespiratory System

    exercise provides vital information about the processes involved in oxygen delivery from the lungs to vasculature in exercising muscle. Oxygen delivery and transport are the deciding factors in how long an individual is able to maintain a given workload during increasing exercise intensities (Whipp, Rossiter & Ward, 2002). Oxygen delivery from the lungs to exercising muscle, along with modulating factors of ventilation will be examined in this section. Oxygen supply in the body relies on ventilation mechanics in order to deliver oxygen rich blood in hemoglobin to exercising muscle. Within the respiratory system, ventilatory areas can be split into conducting zones (trachea & terminal bronchioles) and respiratory zones (alveolar ducts and alveoli); the only area where gas exchange occurs is within the respiratory zone, the conducting zone is referred to as dead space (McArdle, Katch I. & Katch L., 2010a). The process of ventilation is a product of inspiration and expiration (McArdle et al., 2010a). During the process of inspiration, the diaphragm moves down while contracting decreasing intrapulmonic pressure below atmospheric pressure allowing the movement of oxygen from the atmosphere into the alveoli, in a process called alveolar ventilation (McArdle et al., 2010a). Additional inspiratory muscles---namely, the scalene and external intercostal muscles—are recruited during exercise to assist in expanding the ribcage increasing ventilatory capacity (McArdle et al., 2010a).…

Another factor was the competition…
