    This process is characterized by an exercise induced decrease in the pH of the body and may be responsible for peripheral fatigue associated with exercise.

    • Selective alkalosis

    • Hormonal acidosis

    • Metabolic alkalosis

    • Metabolic acidosis

    Correct Answer
    A. Metabolic acidosis
    Explanation
    Metabolic acidosis refers to a condition where there is an excess accumulation of acid or a decrease in bicarbonate levels in the body. In the context of exercise, metabolic acidosis occurs due to the increased production of lactic acid during intense physical activity. This accumulation of acid leads to a decrease in the pH of the body, causing peripheral fatigue. Therefore, metabolic acidosis is the most appropriate explanation for the exercise-induced decrease in pH and peripheral fatigue.

                                            allows athletes to work at higher intensities with the same or less fatigue when compared to training at the same relative intensity.

    • Combo training

    • Power training

    • Agility training

    • Interval training

    Correct Answer
    A. Interval training
    Explanation
    Interval training allows athletes to work at higher intensities with the same or less fatigue when compared to training at the same relative intensity. This is because interval training involves alternating between periods of high-intensity exercise and periods of rest or lower-intensity exercise. By incorporating periods of rest or lower intensity, interval training allows athletes to recover and replenish their energy stores, enabling them to sustain higher intensities during the high-intensity intervals. This type of training also improves cardiovascular fitness, increases aerobic capacity, and enhances the body's ability to tolerate and recover from high-intensity exercise.

    • The cori cycle

    • The phosphagen system

    • Glycolysis

    • Beta oxidation

    Correct Answer
    A. Beta oxidation
    Explanation
    Beta oxidation is the process by which fatty acids are broken down in the mitochondria to generate ATP. This process is slower compared to other energy systems such as the phosphagen system and glycolysis. However, it is an important energy system for long-duration activities as it can produce a large amount of ATP from fat stores. The statement suggests that beta oxidation results in the formation of 129 ATP molecules, indicating its efficiency in energy production.

    Glycogen rates of depletion are related to exercise intensity.  That being said                       glycogen is depleted during high intensity, short duration activities.

    Correct Answer
    muscle
    Explanation
    The correct answer is muscle. The explanation for this answer is that glycogen is stored in the muscles and serves as a fuel source during exercise. When exercise intensity is high, the muscles require more energy, leading to a faster depletion of glycogen stores. Therefore, glycogen depletion is directly related to the intensity of the exercise, and the primary site of glycogen depletion is the muscle tissue.

                                          is the process the body goes through in order to remove the Oxygen debt created during exercise in an attempt to get the body back to its normal state.

    • Oxygen deficit

    • Excess post exercise oxygen consumption

    • Oxygen uptake

    Correct Answer
    A. Excess post exercise oxygen consumption
    Explanation
    Excess post-exercise oxygen consumption (EPOC) is the process the body goes through in order to remove the oxygen debt created during exercise and return the body to its normal state. After intense exercise, the body continues to consume oxygen at an elevated rate to restore depleted energy stores, remove lactic acid, and repair damaged tissues. This increased oxygen consumption leads to an elevated metabolic rate and calorie burn even after the exercise has ended. EPOC plays a crucial role in recovery and helps the body recover from the stress of exercise.

    The process depicted here allows for lactate in the blood to be converted to glucose in the liver - ProProfs

    The process depicted here allows for lactate in the blood to be converted to glucose in the liver

    Correct Answer
    Cori Cycle
    Explanation
    The Cori Cycle is a metabolic pathway that occurs in the liver and muscles. It involves the conversion of lactate, which is produced during anaerobic respiration, back into glucose. This process allows for the recycling of lactate and the production of glucose, which can be used as an energy source. The Cori Cycle is particularly important during periods of intense exercise when muscles produce large amounts of lactate. The lactate is then transported to the liver where it is converted back into glucose and released into the bloodstream to be used by other tissues.

    • Electric System

    • Hormonal System

    Correct Answer(s)
    A. Phosphagen System
    A. Glycollysis
    A. Ocidative System
    Explanation
    The correct answer is Phosphagen System, Glycolysis, and Oxidative System. These three energy systems exist in muscle cells to replenish ATP. The Phosphagen System involves the breakdown of creatine phosphate to produce ATP quickly during short bursts of intense activity. Glycolysis is the process of breaking down glucose to produce ATP in the absence of oxygen. The Oxidative System utilizes oxygen to produce ATP through the breakdown of carbohydrates, fats, and proteins. These systems work together to provide energy for different types and durations of exercise.

    Primary Energy System (s) for the following Duration of event: 2-3 min Intensity of Event: Moderate

    • Phosphagen

    • Fast Gylcolysis

    • Oxidative

    Correct Answer(s)
    A. Fast Gylcolysis
    A. Oxidative
    Explanation
    The event duration of 2-3 minutes and moderate intensity suggest that the primary energy systems used will be Fast Glycolysis and Oxidative. Fast Glycolysis is the breakdown of glucose to produce ATP quickly, providing energy for short bursts of intense activity. Oxidative system, on the other hand, utilizes oxygen to produce ATP and is more efficient for longer duration activities. Since the event falls within the 2-3 minute range, both systems will likely be utilized to meet the energy demands.
