IN SUMMARY
• Endurance training programs that increase VO2 max involve a large muscle mass in dynamic activity for 20 to 60 minutes per session, three or more times per week, at an intensity of 50% to 85% VO2 max. IN SUMMARY
• Although VO2 max increases an average of about 15% to 20% as a result of an endurance training program, the largest training-induced increases in VO2 max generally occur in those genetically gifted individuals that are often referred to as "high responders" to endurance training adaptations
• I Genetic predisposition accounts for about 50% of" one’s V02 max value. Very strenuous and/or pro“! longed endurance training can increase V02 max in normal sedentary individuals by up to 50%
