What is the clinical evidence from this study?

Study design: Cohort. Population: Healthy former physical education students (n=53). Intervention: Aging (33-year follow-up) vs. Baseline measurements in 1949. Primary outcome: Peak aerobic power (oxygen uptake).

What question did this study set out to answer?

Key result

Over a 33-year follow-up, peak aerobic power in former physical education students declined significantly after 21 years but showed no further reduction over the subsequent 12 years.

Implication

Stabilization of peak aerobic power after midlife in active adults should not yet change practice; leaves open whether sustained exercise mitigates late-life decline.

Key Points

Determine long-term changes in peak oxygen uptake, heart rate, and pulmonary ventilation across a 33-year follow-up period in physically active individuals.
Followed 27 female and 26 male former physical education students initially examined in 1949 (mean age 22 and 25 yr, respectively) with repeated assessments in 1970 and 1982.
Measured oxygen uptake, heart rate, and pulmonary ventilation during submaximal and maximal exercise protocols on cycle ergometers and treadmills.
Peak aerobic power decreased from 1949 to 1970 (2.90 to 2.18 l/min in women; 4.09 to 3.28 l/min in men), but exhibited no further reduction between 1970 and 1982.
Peak heart rate declined significantly from 1949 to 1982 (196 to 177 beats/min in women; 190 to 175 beats/min in men; P < 0.05), whereas maximal pulmonary ventilation showed no significant change.
Submaximal heart rate measured at an oxygen uptake of 1.5 l/min remained identical between 1949 and 1982.

Population

53 former physical education students (mean age 22-25 years at baseline) followed for 33 years to assess changes in peak oxygen uptake and related variables.

Outcome

Peak oxygen uptake, heart rate, and pulmonary ventilation during submaximal and maximal exercise on a cycle ergometer and treadmillsurrogate

In a cohort of former physical education students, peak aerobic power declined over the first 21 years but stabilized over the subsequent 12 years, suggesting a potential protective effect of habitual physical activity against age-related fitness decline.
