简要总结
This is an intervention research project, with a pragmatic experimental design of the type Randomized Clinical Trial. Schoolchildren from 6th to 9th grade of both genders, adolescents must be in age group between 10 and 17 years old. enrolled in public schools in the city of Canguçu/RS in the rural zone full-time that have professors with academic training in the area of EF will be allocated in intervention group (IG) and control group (CG). The GI will participate in the inclusion of 15 minutes of functional exercises during the PE class and the GC will continue with the PE classes as planning elaborated by the teachers and pedagogical coordination. The study variables will be organized into main dependents (physical parameters related to health), secondary dependents (parameters behavioral and psychological health-related), characterization of the participants, and independent.
After the 12 weeks of intervention, the data will be collected again, in order to compare the data obtained before the intervention. The expected results after 12 weeks will be that the Group intervention has a significant improvement in the physical, behavioral and psychosocial parameters of health compared to the control group.
详细描述
- OBJECTIVES
General:
As a general objective to evaluate the effects of a fifteen-minute intervention of functional exercises during PE classes on physical, behavioral and psychosocial health parameters in schoolchildren.
Specific:
Check the effects of the intervention with fifteen-minute functional exercises:
- In cardiorespiratory fitness
- In strength, endurance and muscle power
- On speed and agility
- On flexibility
- On body mass index, waist circumference and skinfolds
- In physical activity levels
- In recreational screen time
- In self-concept
- Motivation for participation in PE classes
- In mental health (symptoms of stress, anxiety and depression).

盲法说明
The blinding process will only be in relation to the evaluators of the pre- and post-intervention variables and those responsible for the tabulation and data analysis. Regarding the blinding of the sample and teachers participating in the intervention, it will not be possible to blind the process of clarity and understanding of the intervention in which the group will participate.

入选标准
- •Schoolchildren from the 6th to the 9th grade of both sexes;
- •Regularly enrolled in Full-time schools in the municipal public network of Canguçu/RS in the rural area;
- •Have teachers with academic training in the field of Physical Education
排除标准
- •Students who have disabilities or physical or cognitive limitations that prevent them from performing physical activities and/or compromise the answers to the questionnaires will be excluded from the study analysis. It is important to point out that if there is a student in this situation, they will participate normally in the intervention and measures (if they express their will and their guardians have consented), but their information will not be used.
结局指标
主要结局
Change in Waist Circunference
时间窗: Waist Circunference will be assessed at week 0 (pre-intervention) and week 13 (post-intervention).
Waist Circunference (cm) will be measure using a flexible measuring tape with millimeter resolution positioned at the midpoint between the last rib and the iliac crest according to standardized procedures.
Change in Cardiorespiratory Fitness
时间窗: Cardiorespiratory Fitness will be assessed at week 0 (pre-intervention) and week 13 (post-intervention).
Cardiorespiratory fitness (m) will be measured based on performance in the six-minute run/walk test.
Change in Handgrip Strength
时间窗: Handgrip Strength will be assessed at week 0 (pre-intervention) and week 13 (post-intervention).
The handgrip (kgf) strength will be evaluated by a handgrip dynamometer (Jamar®).
Change in Sum of Triceps and Subscapular Skinfolds
时间窗: Sum of Triceps and Subscapular Skinfolds will be assessed at week 0 (pre-intervention) and week 13 (post-intervention).
Triceps and Subscapular Skinfolds (mm) will be measured by folding a double thickness of skin and adjacent adipose tissue, with index finger and thumb the fold must be pinched to facilitate the measurement and position the plicometer reader upwards according to standardized procedures.
Change in Muscular Strength/Endurance
时间窗: Muscular Strength/Endurance will be assessed at week 0 (pre-intervention) and week 13 (post-intervention).
Muscle strength/endurance (rep/min) will be evaluated by the number of sit-ups performed in one minute.
Change in Lower Limb Power
时间窗: Lower limb power will be assessed at week 0 (pre-intervention) and week 13 (post-intervention).
Lower Limb Power (cm) will be evaluated by the horizontal jump test.
Change in Speed
时间窗: Speed will be assessed at week 0 (pre-intervention) and week 13 (post-intervention).
Speed (s) will be assessed by the twenty meters sprint running test.
Change in Agility
时间窗: Agility will be assessed at week 0 (pre-intervention) and week 13 (post-intervention).
Agility (s) will be assessed by the four by four meters square test.
Change in Flexibility
时间窗: Flexibility will be assessed at week 0 (pre-intervention) and week 13 (post-intervention).
Flexibility (cm) will be assessed by the sit and reach test.
Change in Body Mass Index
时间窗: Body Mass Index will be assessed at week 0 (pre-intervention) and week 13 (post-intervention).
Body Mass Index (kg/m2) will be calculated from the body mass (kg) and height (m) measures by the follow equation: body mass (kg) / height(m)2
次要结局
- Changes in Recreational Screen Time(Recreational Screen Time will be assessed at week 0 (pre-intervention) and week 13 (post-intervention).)
- Changes in Sleep Time(Sleep Time will be assessed at week 0 (pre-intervention) and week 13 (post-intervention).)
- Changes in Physical Activity Level(Physical Activity Level will be assessed at week 0 (pre-intervention) and week 13 (post-intervention).)
- Changes in Motivation to Participate in Physical Education Classes(Motivation to Participate in Physical Education Classes will be assessed at week 0 (pre-intervention) and week 13 (post-intervention).)
- Changes in Physical Self-Concept(Physical Self-Concept will be assessed at week 0 (pre-intervention) and week 13 (post-intervention).)
- Changes in Symptoms of anxiety, depression and stress(Changes in Symptoms of anxiety, depression and stress will be assessed at week 0 (pre-intervention) and week 13 (post-intervention).)
