Background:

The aim was to assess the feasibility and preliminary efficacy of a community-based physical activity (PA) intervention targeting mothers and daughters.

Methods:

A randomized controlled trial of 48 primary school-aged girls and their 40 mothers were randomized to (i) Mothers And Daughters Exercising for Life (MADE4Life) (n = 21 mothers, n = 25 daughters) or (ii) wait-list control (n = 19 mothers, n = 23 daughters). The 8-week program involved 8 sessions; 25-minute separate mothers and daughters education sessions and 60-minutes PA together. Assessments were at baseline, postintervention and 3-month postintervention. Primary outcome measure was daughters’ moderateto-vigorous physical activity (MVPA) (accelerometer). Secondary outcomes included accelerometer-assessed light/moderate/vigorous PA, BMI, waist circumference, body composition, blood pressure, resting heart rate, sedentary behaviors and mothers’ self-reported PA, parenting measures, and cognitions. Intention-to-treat analysis used linear mixed models.

Results:

Recruitment and retention goals were exceeded. Attendance rates, program acceptability and satisfaction were high. There was no significant group-by-time effect for daughters’ %MVPA (–0.08; 95%CI –1.49, 1.33, d = –0.03) or other secondary outcomes for girls (postintervention range d = 0.01 to –0.46). Significant intervention effects were found for mothers’ %VPA (P = .04, d = 0.25) and role modeling (P = .02, d = 0.66).

Conclusion:

MADE4Life was both feasible and acceptable. Although very small effect sizes were found for the daughters, significant changes were seen for mothers (d = 0.25 to 0.66). Future fully powered trials targeting PA in mothers and daughters is warranted.

Findings from three research paradigms that employed aerobic exercise as an independent variable were used to test the hypothesis that aerobic exercise improves cognitive-neuropsychological functioning. The research paradigms were animal intervention studies, cross-sectional human studies, and human intervention studies. Results from studies of animals, usually rodents, provide consistent evidence that aerobic fitness is associated with improved neurobiological and behavioral functioning. Cross-sectional studies with humans indicate a strong positive association between physical activity level and cognitive-neuropsychological performance. However, results from these studies must be interpreted cautiously, as individuals who elect to exercise or not exercise may differ on other variables that could influence cognitive-neuropsychological performance. To date, human intervention studies have not consistently demonstrated cognitive-neuropsychological improvements following exercise training. To satisfactorily test the exercise/cognition hypothesis with humans, carefully controlled intervention studies that last longer than those previously employed are needed.
