abstract="Two performance models relating age, physical activity, and physical performance were evaluated on 5 age cohorts involving more than 6,000 persons ranging in age from 20 to 69 years. Significant age and activity main effects, without 1 Age X Activity interaction, were obtained on 5 fitness measures and 2 activity indexes. These results are inconsistent with predictions from the moderation model, but they fit predictions from a recently formulated tonic and overpractice model of physical performance.<p /><p>Language: en</p>",
