Study Notes
Fundamental Movement Patterns
- Fundamental movement skills are gross motor skills, categorized into body management (bending, twisting), locomotor (crawling, running), and object control (throwing, bouncing).
- Learning occurs through association. Optimal learning environments, effective instruction, and specific feedback are important.
- Six fundamental movement patterns: squats, hip hinge, lunge, push, pull, rotation.
- Valsalva maneuver: forceful exhalation against a closed glottis, increasing intra-abdominal pressure to stabilize the spine, though potentially increasing cardiovascular risks in susceptible individuals.
Energy Systems, Fatigue, and Recovery
- Energy is the capacity to perform work, required for muscle contraction and other biological processes.
- Power is the rate of energy change or work done per unit time.
- Adenosine triphosphate (ATP) is the primary immediate energy source for muscle contraction.
- Phosphate bonds in ATP release energy when broken, and the body must resynthesize ATP as quickly as it's used for continuous muscle contraction.
- Complex organic fuels (carbohydrates, proteins, fats) are broken down to produce ATP.
- Metabolic processes for producing ATP are categorized as anaerobic (no oxygen needed) and aerobic (oxygen needed).
The Phosphagen System
- The immediate energy system, also called the ATP-CP system.
- ATP is broken down into ADP and Pi to release energy for muscle contraction.
- Creatine phosphate (CP) rapidly resynthesizes ATP from ADP and Pi.
- Limited ATP and CP stores allow for short bursts of high-power activities (approximately 10 seconds).
The Glycolytic System
- Uses glucose as fuel.
- Anaerobic glycolysis is the breakdown of glycogen (stored glucose) or glucose into lactate, producing 2-3 ATP molecules per glucose molecule.
- Glycogen is stored in liver and muscles, with blood glucose coming from carbohydrate digestion and glycogen breakdown.
- Rapid ATP production, but unsustainable for extended periods (approximately 60-90 seconds).
- Lactate buildup can momentarily inhibit glycolysis.
The Oxidative System
- Aerobic energy system.
- Utilizes carbohydrates, fats, and proteins as fuel, generating a high number of ATP molecules per fuel molecule.
- Carbohydrate breakdown (aerobic glycolysis) produces up to 39 ATP molecules per glycogen molecule.
- Fat oxidation (aerobic lipolysis) provides a significant energy source, with palmitic acid producing 129 ATP molecules per molecule.
- Protein breakdown provides amino acids for tissue repair and energy production.
- Not a single fuel source is used exclusively in most activities, as power output and intensity dictate which energy system predominates at a given time.
- Excess post-exercise oxygen consumption (EPOC) is the elevated oxygen consumption during recovery.
Cardiorespiratory Anatomy and Physiology
- Pulmonary circulation: pumps deoxygenated blood to the lungs, returns oxygenated blood to the heart.
- Systemic circulation: pumps oxygenated blood to the body, returns deoxygenated blood to the heart.
- Blood flows through the heart: right atrium, tricuspid valve, right ventricle, pulmonary valve, pulmonary arteries (to lungs), pulmonary veins, left atrium, bicuspid valve, left ventricle, aortic valve, aorta.
Minute Ventilation and Respiration
- Minute ventilation (VE): total volume of air inspired or expired per minute.
- Tidal volume (V₁): volume of air moved per breath
- Respiratory frequency (FR): number of breaths per minute.
- Gas exchange occurs via diffusion, with oxygen entering the blood and carbon dioxide leaving it, in the alveoli capillaries.
- Blood pressure (BP) is the force exerted on arterial walls during heart contractions (systolic) and between contractions (diastolic).
- Hypertension is high BP, linked to potential cardiovascular issues.
- Exercise increases systolic BP, but diastolic BP remains relatively constant or increases slightly.
Oxygen Uptake and VO2 Max
- VO2 max: maximum oxygen uptake during maximum exertion.
- Important factors in VO2 max include the heart's pumping capacity, oxygen-carrying blood capacity, and muscle oxygen usage.
- VO2 max declines with age, influenced by various factors.
- Lactate threshold is the point where lactate buildup becomes significant.
Advanced Training Concepts
- Overload principle: progressively increasing training demands to induce adaptation.
- Specificity principle: training should mirror the specific demands of the activity.
- Macrocycle: long-term training period (months to years).
- Mesocycle: intermediate training period (weeks).
- Microcycle: short-term training period (days).
- Periodization: structured adjustment of training variables to optimize performance.
- Tapering: reducing training volume and intensity before competition to reduce fatigue and optimize performance.
- Residual training effects: fitness gains maintained after cessation of training.
- Concurrent training: training multiple energy systems or muscle groups.
