PathFit

• Muscular system


  • Plays a central role in exercises
  • Responsible for generating force and producing movement
  • Exercises target various muscle groups, allowing for the development of strength, endurance, flexibility, and coordination
• Types of muscle contraction


  • Concentric contraction
  • Eccentric contraction
  • Isometric contraction
• Concentric contraction


  Muscle shortens while generating tension
• Eccentric contraction


  Muscle lengthens while under tension
• Isometric contraction


  Muscle generates tension without changing its length
• Skeletal system


  • Provides structural support, facilitates movement, protects internal organs, and serves as a reservoir for minerals
  • Provides the framework for the body, giving it shape and support during exercises
  • Bones, along with ligaments and tendons, create a stable structure that allows muscles to attach and generate force
  • Distributes forces and bears the body's weight during weight-bearing exercises
• Nervous system


  • Coordinates muscle contractions
  • Controls movement patterns
  • Maintains balance and coordination
  • Regulates physiological responses to physical activity
• Motor neurons


  Transmit signals from the brain to the muscles, initiating and coordinating muscle contractions required for movement
• Respiratory system


  • Supplies oxygen to the muscles and removes carbon dioxide and other waste products generated during physical activity
  • Increases respiratory rate and tidal volume to meet the increased oxygen demand of the working muscles
  • Respiratory centers in the brainstem regulate breathing in response to signals from chemoreceptors
• Circulatory system


  • Delivers oxygen-rich blood to the muscles, removes waste products, and regulates temperature
  • Transports oxygen and nutrients to the working muscles and removes waste products
• Cardiovascular system


  • Supplies oxygen and nutrients to the muscles, removes waste products, and regulates temperature
  • Increases heart rate and stroke volume to meet the increased oxygen demand of the working muscles
  • Promotes vascular health, improves blood vessel elasticity, and reduces the risk of cardiovascular diseases
• Hemoglobin


  Binds to oxygen and carries it in the bloodstream to the muscles
• Immune system


  • Protects the body from infections, reduces inflammation, and promotes recovery
  • Temporary suppression during and immediately after intense physical activity
  • Can enhance immune function by promoting the circulation of immune cells, improving lymphatic flow, and increasing the production of antibodies and cytokines
• Endocrine system


  • Regulates metabolism, energy production, and various physiological responses to physical activity
  • Releases hormones to mobilize energy reserves, increase heart rate, and enhance muscle function
  • Contributes to thermoregulation and supports recovery and adaptation to exercise stress
• Integumentary system


  • Regulates body temperature during exercise
  • Provides a protective barrier against physical, chemical, and microbial threats
  • Helps regulate hydration and moisture balance
  • Involved in wound healing and tissue repair following injuries
