Exercise Physiology Adelaide: The Basics of Exercise Physiology

Exercise physiology is the study of how humans respond to acute and chronic exercise (training). This field encompasses all systems that influence physical performance such as the cardiovascular, skeletal muscle and respiratory systems.

Exercise physiology Adelaide places special attention on the muscular system as its actions produce movement and exert force. Muscular adaptations to training depend upon load (intensity), repetitions, rest periods and frequency of workouts.

Metabolic Rate

Fuel breakdown and use to power cells is a rate dependent upon a species, environment, and activity level of an animal. Energy from food consumed is converted to ATP via various metabolic pathways in their bodies – this conversion rate ultimately depends on what species, environment, and level of activity an animal experience.

Fats and carbohydrates provide energy during rest or low intensity exercise, with carbohydrates stored primarily as glycogen and some in muscle cells. Protein can also be utilised as an energy source, but this method is less efficient.

Long term endurance training results in positive cardiac adaptations, including increased early diastolic filling and lower resting and incremental maximal heart rates during exercise. Muscles also experience an increase in glycogen storage capacity while the oxidative system becomes more efficient.

At a cellular level, ATP production takes place through a process known as phosphorylation. This occurs when ADP is broken down to ADP and Phosphocreatine via Krebs Cycle reactions and electron transport chain reactions before being reformed back into ATP for muscle contraction.

Muscle Strength

Muscle strength refers to the amount of force your muscles can exert for a short duration. It plays an essential role in performing everyday tasks such as lifting heavy boxes or carrying children downstairs. Exercise physiology incorporates muscle strength into its evaluation because it affects recovery times between workouts as well as their intensity levels.

Undergoing muscular strength exercises requires activating fast-twitch muscle fibres that rely on less oxygen than slow-twitch fibres to produce power, according to Ian Elwood, C.S.C.S, a trainer from Mission MVNT in Portland. Although fast-twitch fibres produce greater power output they fatigue quicker.

Maximum voluntary contraction (MVC) measures your muscle’s ability to contract at its maximum capacity. MVC is determined by measuring peak force produced during one contraction of a target muscle; testing requires cooperation from participants and may be inaccurate depending on equipment used for testing. Exercise physiology Adelaide studies show that various forms of training cause unique adaptations in neuromuscular systems; for instance, endurance training increases enzyme concentrations and improves fatigue resistance while strength training results in increased myofibrillar protein synthesis and muscle size growth.

Heart Rate

Exercise increases your heart rate to supply oxygen to working muscles. The higher the intensity of a workout is, the faster your heart beats; for example, sprinting can cause one’s pulse rate to reach 160 beats per minute, as opposed to 120 during walking.

Exercise causes an increase in oxygen and substrate consumption for active muscle tissues, and release of carbon dioxide and other waste products, necessitating rapid metabolic, cardiovascular, and respiratory adjustments to be made quickly and effectively.

The cardiovascular system is at the core of these changes and forms the subject of much exercise physiology research. It plays an essential role in clearing away lactate from exercise-generated metabolites as well as helping dissipate heat generated during activity, making homeostasis during exercise all-important for success.

Blood Pressure

Resting blood pressure for healthy individuals typically sits around 120/80; during exercise however, their systolic number (top value) typically increases due to energy production demands. While this rise is normal and should not pose a health risk; too high of a blood pressure level could increase cardiovascular disease risk or other medical issues.

Energy for exercise comes from breaking down food into adenosine triphosphate (ATP), with this process depending on what kind of activity and duration is being undertaken. The pathways can vary depending on which exercise type and length is being conducted.

Exercise physiology Adelaide do more than analyse fitness tests and collect data. They work directly with clients to help improve their health and performance through physical activity.

Endurance refers to one’s ability to maintain physical activity for an extended period, an essential aspect of fitness which can be improved with endurance training as a part of a regular workout routine. Such endurance exercises improve physical health while increasing energy levels and decreasing injury risks.
