The document outlines the physiological effects of aerobic exercises, highlighting their impact on energy consumption, cardiovascular health, respiratory efficiency, metabolic changes, and musculoskeletal benefits. It describes the types of aerobic activities, their adaptations in the body during exercise, and their applications in managing conditions like diabetes and hypertension. Overall, it emphasizes the importance of aerobic exercise in enhancing physical fitness and health.

AEROBIC EXERCISES

2. What is Energy mechanism of
Human body?
9/18/20182
 Average at rest our body consumes 0.25 ltr.
Of Oxygen.
 At exercise around 4-5 ltr of oxygen is
consumed.
 3 – stage energy peroduction.
 100 mtr race in 10 seconds – Anaerobic (CrP)
 400 mtr race in 45 sec – Anaerobic (ATP+LA)
 1 km in 5 minute – Aerobic (Glycolysis+Lipid
metabolism)

3. AEROBIC EXERCISES
9/18/20183
 Aerobic exercise training, or conditioning, is
augmentation of the energy utilization of the
muscle by means of an exercise program.
• Therapeutic Exercise 5thed. Kisner & Colby
 Aerobic exercise (also known as cardio)
is physical exercise of relatively low intensity
that depends primarily on the aerobic energy-
generating process.

6. PHYSIOLOGICAL EFFECTS OF
AEROBIC EXERCISES
9/18/2018Physiological effects of aerobic exercises6
 CARDIOVASCULAR CHANGES
 Exercise pressor response
 Increased Heart Rate
 Reduced peripheral resistance to blood flow
 Increased Cardiac Output

7. PHYSIOLOGICAL EFFECTS OF
AEROBIC EXERCISES
9/18/2018Physiological effects of aerobic exercises7
 RESPIRATORY SYSTEM
 Increase in Minute Ventilation due to increased
respiratory frequency and Tidal volume.
 Increased Oxygen extraction and consumption
 Increased VO2max level

8. PHYSIOLOGICAL EFFECTS OF
AEROBIC EXERCISES
9/18/2018Physiological effects of aerobic exercises8
 METABOLIC CHANGES
 Muscle hypertrophy
 Aerobic ATP production increases due to increased
size of mitochondria
 Glycogen sparing due to increased fat metabolism
 Metabolic adaptations may occur due to changes in
energy requirement and demand.

9. PHYSIOLOGICAL EFFECTS OF
AEROBIC EXERCISES
9/18/2018Physiological effects of aerobic exercises9
 MUSCULOSKELETAL SYSTEM
 Decrease in body fat
 Increase in the breaking strength of bones and
ligaments and the tensile strength of tendons
 Accumulation of Lactic acid in muscle
 Increased temperature of body due to increased blood
flow and metabolism (BMR)

HYPERTENSION
9/18/2018Physiological effects of aerobic exercises17
 Hypoglycemia is the biggest risk for exercises
during Diabetes II
 Aerobic exercise improves level of Glucagon
in blood.
 Endurance training (light – to – moderately
intense)
 Running and cycling
 Brisk walking
 Combination exercises (resisted+endurance)
