  1. Physical fitness contrasts: ECS versus LUB = endurance, coordination, and speed versus powerLOW, powerUP, and balance. EC versus S = endurance and coordination versus speed. E versus C = endurance versus coordination. L versus U = powerLOW versus powerUP. U versus B = powerUP versus balance. Cohort contrasts: Pre1 (linear) = Linear pre-pandemic secular trend. Pre2 (quadratic) = Quadratic pre-pandemic secular trend. Covid contrast 1 = Cohorts 2016–2019 versus 2020–2022. Covid contrast 2 = Cohort 2020 versus 2021. Covid contrast 3 = Cohort 2021 versus 2022. Endurance = cardiorespiratory endurance (i.e., 6-min run test), Coordination  = star-run test, Speed = 20-m linear sprint test, PowerLOW = lower limbs muscle power (i.e., standing long jump test), PowerUP = upper limbs muscle power (i.e., ball-push test), balance = static balance (i.e., one-legged-stance test with eyes closed), VC = variance component, CP = correlation parameter. Theoretically relevant correlations discussed in the text are set in bold. VC for Residual = 0.322
