It is evident that there is a lack of FMS proficiency among adolescents, which may lead to difficulties in developing more advanced sport-specific skills. 1 If this lack

We investigated the effects of calcium supplementation and physical practice on the bone ultrasound properties and trabecular microarchitecture in children. 160 children aged 8−11 were randomly allocated to active or nonactive groups and to receive either a calcium-phosphate or a placebo powder for 6 months. Skeletal status was assessed using an ultrasound technique, which measures the speed of sound (Ad-SoS, m/s) at the phalanx. Bone microarchitecture was characterized by fractal analysis measured on calcaneus radiographs and the result expressed as the Hmean parameter, that has been shown to a good reliability of the bone texture quality. After 6 months, the calcium group had significantly gained Ad-SoS compared to the placebo group (P = 0.01) and Hmean increase was greater in the active than the nonactive group (P < 0.05). Exercise and calcium supplementation had a differential effect on the bone tissue, calcium being rather linked to a systemic effect whereas exercise has acted better onto the skeletal stressed site.

In spite of an extensive knowledge of the physiologic features of exercise during pregnancy, we still lack a comprehensive understanding of the effects of different types, intensities and duration of exercise throughout pregnancy on maternal and fetal well being. The aim of the current study was to examine the influence of an aerobic exercise program throughout pregnancy on gestational age at the moment of delivery.
This study was a randomized controlled trial. Three hundred and twenty Caucasian (Spanish) healthy pregnant women with singleton gestation were randomly assigned to either an exercise (n = 160) or a control (n = 160) group. Gestational age (weeks) and other outcomes were measured. The exercise program included 85 sessions (general fitness class, 3 times/week, 55–60 min/session from weeks 8–10 to weeks 38–39 of pregnancy).
Two hundred and ninety women were analyzed (exercise group EG, n = 138, control group CG, n = 152). The mean gestational age did not differ between groups (EG= 39.7± 1.3 vs CG= 39.6 ± 1.1 weeks, P = .81). Relative to preterm deliveries in EG we found 6 (4.3%) and 11 (7.2%) in CG, (P = .73).
A supervised program of moderate exercise performed throughout pregnancy is not a risk of preterm delivery for healthy pregnant women.

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

additional secondary aim was to assess the feasibility and engagement of the MSIU program. Methods Overview A 3-arm cluster randomized controlled trial (allocation ratio 1∶1∶1) was undertaken in Adelaide, South Australia, between September 2013 and October 2014. Postpartum women were recruited in teams, with

Also, a detailed documentation by a subclassification of PA (e.g., total PA vs. sportive, leisure, household, professional PA) was not provided, while assessment methods were partly not adequate or validated for older impaired persons with and without cognitive impairment.

This study examined exercise-adherence rates and their predictors across 21 randomized controlled trials (RCTs) involving older adults (age ≥ 55 years). On average, participants completed 78% of their prescribed exercise bouts. Adherence tended to be greater in strength- and flexibility-exercise training programs (M = 87%) than in aerobic-exercise training programs (M = 75%). The best adherers were individuals who were fitter at baseline, had a history of a physically active lifestyle, were nonsmokers, and had higher exercise self-efficacy. Different variables predicted adherence (a) at different time points in a RCT. (b) to different types of exercise, and (c) to different aspects of the exercise prescription (i.e., frequency, intensity, and duration). The findings suggest that older adults might be more adherent to exercise prescriptions than younger adults are. There is also a need for more theory-based research to examine predictors of adherence to various aspects of the exercise prescription.
