CanFitPro - FIS Theory Exam (Answered 100% Correctly)

CanFitPro - FIS Theory Exam (Answered 100% Correctly) ATP-CP System (Max effort - very short) Lactic Acid or Glycolytic System (Hard effort) Aerobic or Oxidative (Steady state effort) 3 energy systems Cardiorespiratory capacity Muscular capacity Flexibility three primary components of fitness • Decreased resting Heart Rate • Decreased risk of cardiovascular disease • Improved endurance • Increased stroke volume & cardiac output 4 benefits of training the cardivoscular system _____________ provides the ability to do physical work or perform a physical task. Energy A stable state where all systems are in balance and the demand for energy is met by available energy. homeostasis sarcomere The smallest functional (contracting) unit of a muscle isotonic concentric muscle contracts with enough force to shorten the muscle isotonic eccentric muscle lengthens as it exerts force isometric static contraction - muscle exerts force to counteract opposing force, no change in muscle length false, the first few weeks give gains due to neural adaptation true or false - the gains made over the first few weeks of muscle conditioning are due to increased muscle fibre size. resting length, potential cross bridges A muscle can generate its greatest force at its ________________ _____________ because it's myofilaments are in a position where their ______________ are exposed. faster, slower. So, always do the concentric part of the movement faster, but slow down the eccentric movement to get the muscle closer to exerting its maximal force. IN terms of the speed of movement, __________________ contractions exert maximal force in a concentric movement, whereas ____________ contractions exert more force in an eccentric movement. increase in muscle fibre size increase in contractile strength improved muscular coordination and recruitment improved tendon and ligament strength increased bone strength (density) 5 benefits of muscle conditioning O - prevent osteoporosis C -improve strength for cardiovascular activity S - improved sport performance M - maintain mass (offset age-related sarcopenia) I -reduces injury from overuse W -helps body-weight maintenance F -improves functionality for everyday activities P - improves core strength and posture 8 benefits of weight training
