Study Notes
Principles of Adaptation
- Specificity: Adaptations to resistance training are specific to the type of exercise, muscle group, and intensity used.
- Overload: Gradually increasing the intensity of training is necessary for continued adaptation.
- Progressive: Adaptations occur over time with consistent and progressive training.
Neuromuscular Adaptations
- Neural Drive: Increased neural drive to muscles, resulting in greater muscle activation.
- Motor Unit Recruitment: More efficient recruitment of motor units, leading to increased force production.
- Muscle Fiber Distribution: Shift towards faster, more powerful muscle fibers (Type II).
Muscular Adaptations
- Hypertrophy: Increase in muscle cross-sectional area, leading to increased muscle strength.
- Myofibril Hypertrophy: Increase in contractile proteins, leading to increased force production.
- Sarcoplasmic Hypertrophy: Increase in muscle cell fluid and organelles, leading to increased endurance.
Tendon and Ligament Adaptations
- Tendon Hypertrophy: Increase in tendon size and strength, allowing for greater force transmission.
- Ligament Adaptations: Increased stiffness and strength of ligaments, allowing for greater joint stability.
Metabolic Adaptations
- Increased Myoglobin: Increased storage of oxygen in muscles, allowing for greater endurance.
- Increased Capillarization: Increased blood flow and oxygen delivery to muscles, allowing for greater endurance.
- Increased Mitochondrial Density: Increased energy production and efficiency in muscles.
Chronic Adaptations
- Long-term Increases in Strength: Continued strength gains over time with consistent training.
- Improved Muscle Function: Improved muscle function and coordination, leading to increased athletic performance.
- Reduced Injury Risk: Increased strength and stability of muscles, tendons, and ligaments, leading to reduced injury risk.
