Subclaims¶

q3 i? ANOVA indicated significant differences between exercise groups on fitness measures, cognitive measures, general self-efficacy, somatic symptoms, anxiety and insomnia, and life satisfaction, but no differences on social dysfunction or severe depression. → Reigal 2020

Evidence¶

Reigal 2020¶

Reigal, R. E., Hernández-Mendo, A., Juárez-Ruiz de Mier, R., and Morales-Sánchez, V. (2020). Physical Exercise and Fitness Level Are Related to Cognitive and Psychosocial Functioning in Adolescents. Front. Psychol. 11:1777. https://doi.org/10.3389/fpsyg.2020.01777

q3 · i? · associational · r1

Omnibus ANOVAs across the three exercise-hour groups (n = 208 total) were significant for the listed fitness, cognitive, and psychosocial variables (e.g., VO2max F[2,205] = 38.26, p < 0.001, η2 = 0.27), while "There were no differences between groups in social dysfunction, and severe depression (GHQ)."

"The ANOV As performed indicated that there were differences between the groups in the variables fat mass percentage, horizontal jump test, VO 2max, 5 × 10 speed test, D2-TOT, D2-CON, Symbol Search, Coding, Processing Speed, general self-efficacy, somatic symptoms, anxiety and insomnia, and life satisfaction. There were no differences between groups in social dysfunction, and severe depression (GHQ)."

Discussion¶

Related Claims¶

• GHQ social dysfunction and severe depression show no group differences by exercise hours but are significantly related to physical fitness in correlation and regression — possibly the same claim (merge candidate)
• The most active and fittest adolescent group achieved the best psychosocial indicator scores — a narrower finding that bears on this claim
• Adolescents with high weekly physical exercise hours (more than 4 h/week) show significantly better selective attention, concentration, and processing speed than lower-exercise groups, with no differences between low and moderate groups — a narrower finding that bears on this claim
• Cardiorespiratory fitness predicts nearly all cognitive and psychosocial measures, with anxiety/insomnia predicted by horizontal jump and life satisfaction by fat mass — related
• Cardiorespiratory fitness (VO2max) is the physical fitness measure most strongly correlated with cognitive functioning in adolescents — related
