Aerobic Exercise Recommendations

Adults should perform moderate exercise for 30+ mins, 5 days/week or vigorous for 25+ mins, 3 days/week.

Resistance Exercise Recommendations

Engage all major muscle groups with moderate intensity on 2+ days/week.

Impact of Physical Activity (PA)

Lack of PA is linked to obesity and poor health outcomes in Americans.

Childhood Physical Activity Benefits

Incorporating PA from early age reduces chronic disease risk and improves bone density.

Study Notes

Understanding Physical Activity and Exercise - Chapter 1

  • The American College of Sports Medicine (ACSM) is a leading organization in exercise science, and certification signifies high knowledge and professionalism.
  • ACSM certification opens doors to working with diverse clients, from healthy individuals to those with chronic diseases.
  • Certified Exercise Physiologists (CEP) can work directly with patients in healthcare settings.
  • ACSM certifications are evidence-based, using the latest scientific research for safe and effective exercise programs.
  • ACSM provides ongoing learning opportunities and a network of certified professionals.
  • Physical activity is considered a behavior that encompasses activities like recreation, transportation, occupation, household tasks and exercise.
  • Exercise is a subset of physical activity, while physical activity is a broader category.
  • Different energy systems (ATP-CP, Glycolytic, Oxidative) are utilized depending on the duration and intensity of the exercise.
  • Physical fitness is categorized into health-related (body composition, cardiovascular endurance, muscular strength/endurance, flexibility) and skill-related (agility, coordination, reaction time, balance, speed, power).
  • Physical activity has been recognized as important for a long time. Concepts of physical training have been important since Socrates' time and have evolved through institutions such as the Harvard Fatigue Lab into modern practices like the 1995 Joint Position Statement.
  • The ACSM was founded in 1954 and is a collection of researchers, practitioners, and educators offering certifications like the Certified Exercise Physiologists (ACSM-EP).
  • Individuals without prior medical clearance can safely start low-to-moderate-intensity physical activity programs. Vigorous-intensity programs require supervision by a qualified professional.
  • EP-Cs need current knowledge in basic and/or advanced life support training, and must be aware of cardiovascular disease (CVD) signs and symptoms.
  • Sudden cardiac death risk is higher among sedentary individuals.
  • Musculoskeletal injuries are most frequent in weight-bearing or repetitive motion activities, such as team sports. Re-injury risk is higher for those with previous injuries. Benefits of exercise still outweigh these risks.
