Abstract

During early adulthood, a phase in which the central nervous system displays considerable plasticity and in which important cognitive traits are shaped, the effects of exercise on cognition remain poorly understood. We performed a cohort study of all Swedish men born in 1950 through 1976 who were enlisted for military service at age 18 ( N = 1,221,727). Of these, 268,496 were full-sibling pairs, 3,147 twin pairs, and 1,432 monozygotic twin pairs. Physical fitness and intelligence performance data were collected during conscription examinations and linked with other national databases for information on school achievement, socioeconomic status, and sibship. Relationships between cardiovascular fitness and intelligence at age 18 were evaluated by linear models in the total cohort and in subgroups of full-sibling pairs and twin pairs. Cardiovascular fitness, as measured by ergometer cycling, positively associated with intelligence after adjusting for relevant confounders (regression coefficient b = 0.172; 95% CI, 0.168–0.176). Similar results were obtained within monozygotic twin pairs. In contrast, muscle strength was not associated with cognitive performance. Cross-twin cross-trait analyses showed that the associations were primarily explained by individual specific, non-shared environmental influences (≥80%), whereas heritability explained <15% of covariation. Cardiovascular fitness changes between age 15 and 18 y predicted cognitive performance at 18 y. Cox proportional-hazards models showed that cardiovascular fitness at age 18 y predicted educational achievements later in life. These data substantiate that physical exercise could be an important instrument for public health initiatives to optimize educational achievements, cognitive performance, as well as disease prevention at the society level.

  • Cardiovascular fitness positively correlates with cognition in young adults and preserves cognitive performance with aging.

    “while cardiovascular fitness positively correlates with cognition in young adults (89) and preserves cognitive performance with aging (90).”

  • In the longitudinal Swedish study, between ages 15 and 18, those with top 10% improvement in cardiovascular fitness had the highest enhancement of global intelligence, logical, verbal, visuospatial, and technical scores, while those with declines had less than mean intelligence scores.

    “The longitudinal arm of the Swedish study showed that between the ages of 15 and 18 yrs of age those with the top 10% of improvement in cardiovascular fitness scores had highest enhancement of global intelligence, logical, verbal, visuospatial, and technical scores while those subjects with declines in cardiovascular fitness had less than mean intelligence scores.”

  • In a Swedish cohort of men born 1950-1976 enlisted at age 18, cardiovascular fitness measured by ergometer cycling was positively associated with global intelligence scores, with aerobic capacity most strongly associated with logic and verbal intelligence.

    “A cohort study of Swedish men born in 1950 through 1976 who were enlisted for military service at age 18 (N = 1,221,727) (1) reported that cardiovascular fitness, as measured by ergometer cycling, was positively associated with global intelligence scores with aerobic capacity most strongly associated with logic and verbal intelligence.”

  • Better cardiovascular fitness at age 18 was associated with higher socioeconomic status and educational attainment later in life.

    “Further, an association between better cardiovascular fitness at age 18 yrs, a higher socioeconomic status, and educational attainment later in life existed.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
