Moderators of Perceived Effort in Adolescent Rowers During a Graded Exercise Test.

ABSTRACT: Physical activity promotes mental health. A key factor is self-regulation. In the field of sports, self-regulation is related to the psychophysiological competence of rating of perceived effort (RPE). It was reported that adolescents have lower RPE competencies than adults, and it was hypothesized that this effect depends on physiological and cognitive development. The present study investigated in a sample of adolescents whether the RPE is related to basic cognitive competencies. Twelve rowers performed cognitive tests and a graded exercise test on a rowing ergometer, in which they continuously rated their perceived effort. Objective load measures and subjective perceptions were highly correlated (rho = 0.95-0.99). Furthermore, these correlations were inter-individually moderated by measures of mental speed and spontaneous flexibility. The results confirm the significance of basal cognitive competencies for conscious load perception. It is discussed whether regular sport has beneficial effects on the development of RPE competencies by enhancing cognitive regulation.

Project description:BackgroundThe purpose was to explore whether baseline sociodemographic and physical characteristics moderated effects of an intervention on moderate-to-vigorous physical activity (MVPA), percent body fat, body mass index z-score, and cardiorespiratory fitness (CRF) at post intervention, relative to the control condition.MethodsA secondary analysis of data from a group randomized trial including 24 schools (12 intervention and 12 control; N = 1519 girls) was conducted. Age, ethnicity, race, socioeconomic status, and pubertal stage were assessed via survey. Height, weight, MVPA (min/h), percent body fat, and CRF were measured. Mixed-effects linear models were performed.ResultsCompared to the control, the intervention increased overweight and obese girls' CRF (b = 0.28, p = 0.049; b = 0.31, p < 0.01, respectively), but not healthy weight girls' CRF (b = 0.04, p = 0.706). Pre- to mid-puberty girls in the intervention group had slightly lower post-intervention MVPA than those in the control (3.04 vs. 3.31, p = 0.055), while late to post-puberty intervention and control girls' post-intervention MVPA was similar (3.12 vs. 3.04, p = 0.542).ConclusionsA PA intervention can improve overweight and obese girls' CRF, possibly attenuating their cardiovascular risk. Effective strategies are needed to assist adolescent girls, especially those in pre- to mid-puberty, in maintaining their MVPA after an intervention ends.ImpactModerators of physical activity intervention effects among adolescent girls are important to identify because the effectiveness of these interventions to date in this population has been limited. This article contributes to the notable gap in knowledge regarding moderators in physical activity interventions involving adolescent girls, particularly baseline characteristics that may moderate their responses to physical activity interventions. Awareness of the moderators can be useful for determining the type of intervention that may be successful in subgroups of adolescent girls and for tailoring a physical activity intervention to optimally meet each girl's needs to achieve maximal effects. Findings show that weight status moderated the intervention effects on cardiorespiratory fitness. Compared to the control condition, the intervention increased overweight and obese, but not healthy weight, girls' cardiorespiratory fitness. A physical activity intervention can improve overweight and obese girls' cardiorespiratory fitness, possibly attenuating their cardiovascular risk. Therefore, it is essential to include overweight and obese girls in PA interventions to help them reap this important benefit.
