Aerobic Fitness Generally considered the most

important factor of good health and fitness

Aerobic fitness is linked to reduced risk of high blood pressure, coronary heart disease, obesity, diabetes, osteoporosis, and some forms of cancer

Concept Sequence Elementary level: teach about the heart’s

response to various intensities of activity; Middle school: teach students about aerobic

adaptations based on improved health and fitness levels

High School: help students to plan an exercise program based on their needs/goals Work through THRZs and specific FITT principles

FITT Based on fitness goals & age of

students Elementary Adolescents (11+) Those adolescents desiring performance

benefits

Intensity Max HR method: 208- (threshold -age)

THR zone: multiply MHR by the intensity percentages desired (60-90%)

Once lower zone is determined, next zone is 10% higher

Karvonen method: will determine HRR THRZ=[[[208-(.7 x age)] -RHR] x %] + RHR

Training Methods Continuous

K-2: 3-5 min 3-5: 10 min Middle & high: 20 + min Overload & progression: increase the

intensity or duration to provide additional health or fitness benefits

Circuit training: Intensity and type of activities can vary

from station to station Adjust the intensity by altering the time

spent at a station or by changing the rest interval

Should be aerobic in nature Incorporate aerobic work through skill tasks

Interval training: alternates short activity with rest periods Natural intermittent activity of young

children Although anaerobic in nature,

maintaining short rest intervals keeps the activity more aerobic; HR will not recovery fully

Safety Build rest intervals for younger children Make rest intervals optional for older Children will produce more body heat

than adults; provide water breaks Avoid hot, humid weather with younger

children; use good judgment with older students

Tasks Construct the

following: Continuous activities

for all three levels of students

Circuit activities for all three levels

Interval activities for all three levels
