Document Summary
Experts believed children"s systems were unable to function properly during extended physical work: previous measures of blood vessels misinterpreted, myth has persisted for decades. Sociocultural constraint, which influences structural constraint: poor child conditioning believed to persist into adulthood. As the adult wouldn"t had the capacity to be active (structural), and therefore could also not be confident enough to engage in pa (functional) St exercise: vigorous and intense bursts of energy (~10 sec, relies on anaerobic energy systems (measured by anaerobic power and endurance) Initial burst depletes local o2 and energy stores (as duration increase, further emphasis is placed on aerobic systems) At any age, anaerobic performance dependent on: body size (e. g. , muscle size, fuel sources (e. g. , ability to metabolize fuel sources, o2 delivery. Children have lower absolute energy stores compared to adults: as their muscle mass increases, so does the energy reserves, work output increases .
