简要总结
Currently, 10 million children participate in afterschool programs (ASPs) each day, and ASPs provide a great opportunity to enhance children's health outside of the regular school environment, particularly given the decline in physical education. This proposed, randomized cluster, controlled trial will examine the immediate (pre- to post-test) and sustained (1-year post-intervention follow-up) effects of CHAMP-ASP on physical activity (primary outcome), motor performance, perceived motor competence, health-related physical fitness, and weight status. CHAMP-ASP will be implemented by ASP staff and will be conducted in ASPs located in Ypsilanti/Ann Arbor, Michigan. Children (N = 264; CHAMP-ASP=132 and control=132) K-2 graders (typically ages 5-8 years) will participate 35 minutes/day X 3-4 days/week for 19 weeks (dose of 1995 - 2240 minutes). The aims are to: a) examine the immediate and sustained effects of CHAMP-ASP on physical activity, motor performance, and perceived motor competence relative to the control ASP, b) examine the immediate and sustained effects of CHAMP-ASP on secondary health outcomes - health-related physical fitness (cardiorespiratory fitness, muscular strength), and weight status compared to children in schools randomized to control ASP, and c) determine if perceived motor competence mediates the effect of CHAMP-ASP on moderate-to-vigorous physical activity.
详细描述
Promoting health-enhancing and sustainable physical activity levels across childhood and adolescence contributes to adult health. The Children's Health Activity Motor Program (CHAMP) is an evidence-based intervention that demonstrates impactful results on motor performance, perceived motor competence, and physical activity in physical education and movement-based settings. Currently, 10 million children participate in afterschool programs (ASPs) each day, and ASPs provide a great opportunity to enhance children's health outside of the regular school environment, particularly given the decline in physical education. This proposed, randomized cluster, controlled trial will examine the immediate (pre- to post-test) and sustained (1-year post-intervention follow-up) effects of CHAMP-ASP on physical activity (primary outcome), motor performance, perceived motor competence, health-related physical fitness, and weight status. CHAMP-ASP will be implemented by ASP staff and will be conducted in ASPs located in Ypsilanti/Ann Arbor, Michigan. Children (N = 264; CHAMP-ASP=132 and control=132) K-2 graders (typically ages 5-8 years) will participate 35 minutes/day X 3-4 days/week for 19 weeks (dose of 1995 - 2240 minutes). The aims are to: a) examine the immediate and sustained effects of CHAMP-ASP on physical activity, motor performance, and perceived motor competence relative to the control ASP, b) examine the immediate and sustained effects of CHAMP-ASP on secondary health outcomes - health-related physical fitness (cardiorespiratory fitness, muscular strength), and weight status compared to children in schools randomized to control ASP, and c) determine if perceived motor competence mediates the effect of CHAMP-ASP on moderate-to-vigorous physical activity. The long-term goal is to provide a sustainable, ecologically-relevant, and evidence-based program during the early elementary years that is health-enhancing and increases physical activity in school-age children. Findings could significantly influence future physical activity interventions and support a sustainable, ecologically-relevant (delivered by ASP staff) evidence-based program (i.e., CHAMP) that contributes to long-term health-enhancing physical activity and health in children.

研究组 & 干预措施
CHAMP-ASP
CHAMP, is a mastery climate motor skills intervention, that provides children the opportunity to establish behaviors that reinforce decision-making while participating in a motor activity tasks. Children will participate in CHAMP for 35 minutes/day 3-4 days per week for 19 weeks.
Each 35-min session consists of three parts:
- 3-5 min of motor skill introductory activity that includes a group motor activity, the teaching of the lesson that includes a demonstration and understanding of developmentally appropriate learning clues;
- 25 min of motor skill instruction and practice (i.e., 'active motor engagement'), participants will be encouraged to move through 3-4 motor activity stations that align with the TARGET structure; and
- 3 -5 min motor skill closure activity that involves a review of the lesson and critical elements.
干预措施: Motor Skills Intervention (Behavioral)
Control - Standard of Practice
The Control (standard of practice) condition will be the school typical ASP and will be implemented according to the existing procedures.
结局指标
主要结局
Changes in Motor Competence - product measures
时间窗: baseline, post-intervention (i.e., 24 weeks post baseline), and 1 year post-intervention follow-up
Product scores will use throwing speed, kicking speed, jump distance, running speed, and hopping speed. Product score will vary for each participant (i.e., kick, run, hopping, and throw velocity along with jumping distance - faster scores and greater distance are indicators of better MC).
Changes in Physical Activity
时间窗: baseline, post-intervention (i.e., 24 weeks post baseline), and 1 year post-intervention follow-up
Actigraph GTX3+ tri-axial accelerometer will be used to measure the frequency, intensity, and duration of PA among children during the ASP and in free-living settings. Participants will be asked to wear the same accelerometer for 7 full days (5 week and 2 weekend days). Data will be set to collect data in raw mode (30 Hz), and will be processed using ActiLife software or other, more advanced techniques, such as machine learning approaches.
Changes in Health-related fitness - Cardiorespiratory endurance
时间窗: baseline, post-intervention (i.e., 24 weeks post baseline), and 1 year post-intervention follow-up
Cardiorespiratory endurance will be assessed with a 6-min walk test. For the 6-min walk test, the children walk as fast as possible around two cones for 6 minutes.
Changes in Health-related fitness - Muscular Strength
时间窗: baseline, post-intervention (i.e., 24 weeks post baseline), and 1 year post-intervention follow-up
Muscular strength will be assessed with test of handgrip strength. Upper body strength will be assessed using a hand grip strength with a dynamometer, which has been deemed reliable and valid in 6-12-year-olds \[62\]. Grip will be appropriately adjusted for size, and two trials on the right and left sides (elbow extended) will be assessed (muscular strength). The sum of maximum score (kg) of two trials for each hand will be used in analyses.
Changes in Motor Competence - process measures
时间窗: baseline, post-intervention (i.e., 24 weeks post baseline), and 1 year post-intervention follow-up
Process scores will be assessed with the Test of Gross Motor Development (TGMD, 3rd edition); scores from the two subscales (locomotor and ball skills) will be reported as raw scores for each skills and an overall score (total MC score). The project will assess changes overtime for this measure
Changes in Health-related fitness - Body Composition
时间窗: baseline, post-intervention (i.e., 24 weeks post baseline), and 1 year post-intervention follow-up
Body composition (i.e., body fat) will be assessed with bioelectrical impedance. Body fat percentage will be the average of two measurements assessed (to the nearest 0.1%, respectively) with a bioelectric impedance analysis scale (Tanita). The assessment will be completed in a designated, private area
