Exercise Physiology Quiz

Explain the role of muscle physiology during exercise.

• Muscle physiology is essential for generating force, producing movement, and regulating body temperature during exercise.

• Muscle physiology is primarily responsible for mental focus during exercise.

• Muscle physiology has no impact on energy production during exercise.

• Muscle physiology is only important for flexibility during exercise.

Discuss the different energy systems involved in physical activity.

• Calorific system

• Adenosine system

• Phosphagen system, glycolytic system, and oxidative system.

• Krebs cycle system

How does the cardiovascular system respond to exercise?

• The cardiovascular system responds to exercise by decreasing heart rate

• The cardiovascular system responds to exercise by increasing heart rate, pumping more blood to the muscles, and improving oxygen delivery.

• The cardiovascular system responds to exercise by impairing oxygen delivery

• The cardiovascular system responds to exercise by reducing blood flow to the muscles

What are the principles of training in the context of physical activity?

• Specificity, Overload, Progression, Reversibility, Individuality

• Maintenance

• Consistency

• Variability

Describe the process of muscle contraction during exercise.

• Muscle contraction is caused by the release of adrenaline during exercise.

• During exercise, muscle contraction is primarily driven by the nervous system.

• Muscle contraction during exercise is initiated by an action potential, leading to calcium release, actin-myosin cross-bridge formation, and ATP-dependent myosin detachment.

• The process of muscle contraction in exercise involves the direct interaction of actin and myosin without calcium release.

Compare and contrast aerobic and anaerobic energy systems.

• Aerobic energy system relies on oxygen and can sustain energy production for longer durations, while anaerobic energy system does not require oxygen and produces energy quickly for short bursts.

• Aerobic energy system is used for short bursts of energy production.

• Aerobic energy system requires more oxygen than anaerobic energy system.

• Anaerobic energy system is more efficient than aerobic energy system.

What are the adaptations that occur in the cardiovascular system with regular exercise?

• Decreased stroke volume

• Reduced oxygen delivery to tissues

• Increased stroke volume, improved cardiac output, enhanced oxygen delivery to tissues, lower resting heart rate, reduced blood pressure

• Worsened cardiac output

How can proper recovery enhance performance in physical activity?

• Proper recovery increases the risk of injury during physical activity

• Proper recovery hinders the body's ability to replenish energy stores

• Proper recovery allows the body to repair and rebuild muscle tissues, replenish energy stores, reduce the risk of injury, and improve overall fitness levels.

• Proper recovery leads to decreased muscle mass and strength

What is the significance of oxygen consumption in exercise physiology?

• Oxygen consumption is irrelevant in exercise physiology

• Oxygen consumption is only important for short bursts of activity

• Oxygen consumption only affects muscle strength

• Oxygen consumption in exercise physiology is significant as it indicates the body's aerobic capacity and energy production efficiency.

Explain the concept of muscle fatigue during exercise.

• Muscle fatigue during exercise is caused by factors such as metabolic byproducts, energy depletion, and central nervous system fatigue.

• Muscle fatigue is caused by lack of motivation

• Muscle fatigue is a result of dehydration

• Muscle fatigue is due to excessive stretching
