Study Notes
Muscular Strength and Endurance
- Improved functioning from muscular strength training can lead to stronger bones.
- Muscles constitute over 40% of a person's body mass.
- Muscular strength refers to the maximum amount of weight that can be pushed or lifted.
- Weight training significantly impacts skeletal muscles' development and function.
- In certain sports, muscular strength is prioritized over muscular endurance.
- Key components found in every skeletal muscle include muscle fibers, nerves, connective tissue, and blood vessels.
- High levels of muscular fitness are associated with a reduced risk of chronic diseases.
- Strength training reduces injury risk by enhancing the strength of tendons, ligaments, and cartilage.
- Hyperplasia is a theory of muscle growth where muscle fibers can split and form new fibers.
- Differences in muscle growth rates between individuals may not be attributed to the number of muscle fibers at birth.
- Improvements in muscular strength also enhance muscular endurance.
- Increased muscle mass leads to a heightened metabolism, resulting in decreased body fat.
- Muscle weakening with age is attributed to disconnections between motor nerves and muscle fibers.
- For individuals with sarcopenia, increasing supplements and adopting a healthier diet can prevent progression of the condition.
- To increase muscular endurance, activities should enhance muscle cell size and blood supply to the muscles.
- Slow-twitch muscle fibers are most beneficial for marathon running.
- Engaging in regular running is likely to increase muscular endurance.
- The theories of hypertrophy and hyperplasia regarding muscle growth are both challenging to verify in human studies.
