| Abstract|| |
Background: In recent years, yoga programs in childhood have been implemented in schools, to promote the development for children.
Aim: To investigate the effects of yoga program in physical education classes on the motor abilities and social behavior parameters of 6–8-year-old children.
Methods: The study included 16 children from the 1st grade of a public elementary school in the South of Brazil. The children participated in a 12-week intervention, twice weekly, with 45 min each session. To assess children's performance, we used the Bruininks-Oseretsky Test of Motor Proficiency - Second Edition, the flexibility test (sit and reach – Eurofit, 1988), the Pictorial Scale of Perceived Competence and Social Acceptance for Young Children and semi-structured interviews with children, parents, and classroom' teacher. Data were analyzed with Wilcoxon test and level of significance was 5%.
Results: The yoga program was well accepted by children, children also demonstrated significant and positive changes in overall motor abilities scores (balance, strength, and flexibility). In addition, the interviews reported changing in social behavior and the use of the knowledge learned in the program in contexts outside of school.
Conclusion: These findings suggest that the implementation of yoga practice in physical education lessons contributed to children's development.

| Introduction|| |
Motor skill intervention programs in childhood have been effective in providing participants benefits on motor, affective, and social development. Recognizing the benefits of yoga' practice to promote overall health, in recent years, yoga programs for children have been implemented in several countries ,,, and recently also in Brazil., Although yoga is an ancient practice that seeks a balance between the body, mind and emotions  and the literature highlight its benefits on the motor, physical, cognitive, and social aspects,,, its effectiveness on child development is scarce.
Yoga programs have gain popularity; however, there is a lack of studies in this field, especially involving school-age children. Furthermore, studies are very restricted and focus on the analysis of few aspects of participants' improvements.,, The objective of this study was to investigate the effects of a 12-week yoga program implemented in a Physical Education curriculum on the motor, physical, and behavioral parameters of 6–8-year-old children. Our hypothesis was that through a yoga program, children would improve their motor abilities and physical capacities, and also present some positive changes in behavior toward yoga practice.
| Methods|| |
This study is characterized as a quasi-experimental study with mixed method, which was chosen to integrate the results and produce a relationship between the findings. The study was approved by the University's Ethics Committee (no. 2003109).
The selection of the sample was intentional, according to children's and parents' acceptance. The study included 16 children (8 males and 8 females), aged 6–8 years old, who had no previous experience with yoga. The children were enrolled in the 1st grade of an elementary public school located in the periphery of a major city in the South of Brazil. One of the children had a diagnosis of autism; none of the others were diagnosed with disabilities. The informed consent was obtained from the parents and/or legal guardians and the school board of education.
The balance, running speed and agility, and strength subtests of the Bruininks-Oseretsky Test of Motor Proficiency - Second Edition were used to assess children motor abilities. The performance of the child in each task generated a gross score, and the sum of the tasks generated the total raw score, which was converted to a standard score according to the child's sex and age. For this study, we used the results by task and the total raw score for each subtest.
A version of the sit and reach from Eurofit test  was used to assess children flexibility. The children sited on the floor barefoot and with legs stretched out straight ahead. Both knees locked and pressed flat to the floor. Children placed their heels on the mark and then with palms facing downward and the hands on top of each other reached forward along the measuring. Children hold the position for seconds while the distance was recorded in centimeters. The better of two attempts was considered.
The Pictorial Scale of Perceived Competence and Social Acceptance for Young Children (PSPCSA) was used to assess the children perceptions of competence and social acceptance. This scale consists of 24 items organized into four subscales: Perceived cognitive and motor competence, social and maternal acceptance. Each question includes two figures: One of these figures represents a competent/accepted child, and the other a child not as competent/accepted. After choosing which figure feels more alike them, children must decide how much the level of concordance (range: From 1 [low proficiency/acceptance] to 4 [high competence/acceptance]). The sum of the questions result in the subscale score, and the sum of the subscales results in the total score.
To assess behavioral toward yoga, semi-structured interviews with the children and the classroom teacher were conducted. The interview of the children involved questions regarding the meaning of yoga practice, the activities they most liked to do, the practice outside of school, and the interest to continue practicing. The teacher's interview looked at issues relating to expectations in regards to the yoga program and her opinion after the program finished. In addition, children's behavioral changes that were visibly observed and other observations related to the yoga program were also questioned.
A questionnaire was sent home to parents or the legal guardians of children. The questions addressed the impact of yoga classes in the home environment as well as their perceptions of the influence of the yoga program in the life of their children.
The yoga program was implemented in the physical education classes during 12 weeks, twice a week for 45 min each lesson. Since the public school has no gym or other safety space, the lessons were implemented in the children classroom. A student-centered approach of teaching was implemented. Appropriated practices were provided with a yoga movement curriculum with scope and sequence based on children the initial level of performance in order enhances cognitive, social, and motor development. The teacher used direct and indirect learning strategies, encouraging children do modeled movements, and to discovery the different ways to move., The instruction was meaningful and adequate to the children level of understanding, using simple words, and cue word to perform the yoga postures. The teacher also encourages the self-expression throughout the movement ,, and equally encourages boys and girls as well the child with disability to achieve success and cooperate with each other. Different skill levels of yoga tasks were presented in each session that encompassed group diversity of skills levels. The teacher strategies also supported the autonomy of children, personal and group achievements, and the active participation in decision-making during the learning process.,,,
Teacher also employed a strategy of “gymnastics storied” in which yoga postures were practiced in accordance with different children's books. Stretching and massage in pairs, meditation, and relaxation as well as games and music related to the practice of yoga were also implemented. In addition, the classes emphasized the breathing awareness and the adoption of basic values of social interaction, nonviolence, truthfulness, respect with themselves and the others, and cooperation.
Statistical analysis was conducted using SPSS-20.0 (Statistical Package for Social Sciences, IBM). Descriptive statistics were presented (median, quartiles, minimum, and maximum), and due to the small number of participants and non-normality distribution of the data, nonparametric analyses were used adopting P ≤ 0.05. The Wilcoxon test was used to compare the pre- to post-intervention changes in the raw scores for the tasks and subtests (balance, running speed and agility, strength, and flexibility) and in the PSPCSA.
Using the children's semi-structured interviews, convergent meanings were organized and resulted in three categories: (1) Content learned in the program, (2) desire to sustain yoga practice over time, and (3) self-perceptions of intervention impact. Data reduction from the children interviews into the three categories was conducted using of frequencies of behavior, presented in figures. The speeches more representative of these three categories also were presented.
| Results|| |
Positive changes, from pre- to post-intervention, were observed in the balance subtest and in the following tasks: B2 (walking on a line), B5 (walking touching heel and toes on the line), B6 (staying stabilized with one leg over the line and with eyes closed), B8 (staying stabilized touching heel and toes on the balance beam) [Table 1].

Running speed and agility
Positive changes, from pre- to post-intervention, were observed in the running speed and agility subtest and RSA2 task (set the pace). A tendency to significance was observed in the RSA5 task (jump sideways with feet together) [Table 1].
Strength and flexibility
A positive change from pre- to post-intervention was observed in the strength subtest and the following strength task: S5 task (lift arms and legs in the prone position). Positive changes, from pre- to post-intervention, were also observed for flexibility scores [Table 1].
Regarding cognitive and motor perceived competence, as well as for the maternal and social acceptance, there were no significant differences from pre- to post-intervention [Table 2].
Content learned in the program
[Figure 1] shows the frequency of children's answers about what they have learned in yoga classes. The majority of the children recall the postures, the fun activities as well as the breathing exercises learned in the program. Children also highlighted how important were being these tools and how they were using this in their lives. The following speech emphasizes the children's meaning related to the yoga program,

“We learned that when we are in bad times we have to do yoga because it calms us. It means that calms the heart.” (Speech 1)
Desire to sustain yoga practice over time
When questioned about the desire for future practice, all children expressed that they would like to continue practicing yoga at school in their physical education lessons (n = 15). When asked why they would like to continue the yoga practice, children responses reflected different desires, detailed in [Figure 2], with the prevalence of “nice activity” and “relax and calm feelings” as answers. Children justified this desire relating to positive feelings, overcome difficulties, sadness, and fears. Some of the discourses listed below also reflect their thoughts about this theme and also express how they felt great during the yoga classes:

“Yoga is for us to relax, to feel better and to feel calm while in sad and emotional moments” (Speech 2);
Yoga is breathing, to breathe better, for when we feel sad, for when we are in a bad mood, then Yoga does well” (Speech 3);
“Yoga is something that can make us feel calmer and more relaxed in the days that we are mad or angry.” (Speech 4)
Self-perceptions of intervention impact
When questioned about their feelings related to changes after practicing yoga, the majority of children, although addressing the question with different perceptions, recalled increments in sensations of calm, courage, good behavior, and happiness as well as the reduction of fear [Figure 3]. Some speeches also portrayed improvements in social interactions and in the perceptions of doing better. The following discourses portrait these feelings about this theme:
|Figure 3: Frequency of children's responses relating to self-perceived changes after practicing yoga|

“And I feel that I'm becoming a little better at what I do” (Speech 5);
“The change is that now I'm more happy, I don't have nightmares anymore. I'm also not afraid. Now I'm happy” (Speech 6);
“I felt good, then my friends liked me and wanted to always play with me for them learn” (Speech 7);
“It's because when I'm afraid of something I say that: HAAAAAAAAA, (referring to the HAAA breath) I do it because then I get braver” (Speech 8);
“It is for calm down, to the brain become intelligent. Now I'm better behaved because you made a lot of cool stuff.” (Speech 9)
The children also reported that they carried out the practice at home to show or teach their parents (n = 3), to feel better (n = 1), to improve their health (n = 1), because it is a cool practice (n = 2), and because she/he likes (n = 1). One child also reported not only the personal benefits of yoga but also the positive impact extended to her family, specially related to health aspects. In regards to her thought about this theme, the student affirmed:
“I saw that yoga does well for my health, and also for my parents' and my family's health.” (Speech 10)
The classroom teacher stated that the children were in general more calm and concentrated. She also highlighted that the students were very affectionate to the yoga classes, and she said that the values of respect developed and discussed in the yoga classes had impact on her classes by improving children positive interactions.
Although only half of the parents returned the questionnaire, the answers demonstrated that in the parents' perceptions, most of children started to be more active at home practicing in the free times the postures learned in the program (n = 6). Parents also reported that the children were more relaxed and calm (n = 4), and parents noticed improvements on children's posture (n = 1) and breathing (n = 1).
| Discussion|| |
This study was conducted to analyze the effects of yoga practice on the motor, physical, and behavioral parameters of 6–8-year-old children. Our findings suggest positive improvements on the static and dynamic balance, and strength and flexibility; the participants also reported positive feelings related to the yoga practice.
Regarding balance, all the improvements corroborate with previous studies that also suggested that the practice of yoga promotes significant gains on the static and dynamic balance of children.,,, We suggest that these gains could be related to the practice of some yoga postures, such as the airplane (Virabhadrasana C), tree (Vrksasana), surfer (Virabhadrasana B), and star (Utthita Trikonasana) that requires support on one foot, the trunk tilt forward and also generating instability and the need to working in balance.
The children's ability to speed running and performed agility tasks showed improvement, gains were observed during the tasks of set the pace and jump sideways with feet together. No studies were found related to the assessment of these abilities after the practice of yoga in children that to some extension limits our possibilities to compare results. It has been suggested that yoga promotes improvements in motor coordination and general motor control, consequently, could generate improvements in total body coordination and temporal organization, which are essential features perform speed and agility tests. Further studies are necessary to improve the yoga effects on the speed and agility of children.
The results observed in this study regarding children enhancements on strength received support from three previous. Researchers reported visible improvements on strength as a result of participation on a yoga intervention.,, In addition, increases in the median were large [Table 1], which indicate a probable limitation to achieve significance in some strength tasks due to the reduction in number of children in this study. Moreover, the strength subtest showed significant and positive change, so the discrete changes (small increments) of each task were sufficient to indicate positives changes in strength pattern of children. During the program, several yoga postures emphasize this physical capacity, such as superman (Salabhasana), boat (Navasana), invisible chair (Utkatanasana), and half bridge (Setu Bandhasana). These postures that require the work of different muscle groups, such as dorsal and abdominal region, as well as upper and lower limbs, that may have influenced the positive results observed in children performance.
The positive increments in flexibility performance also corroborate with previous research., We suggested that these gains are result from the practice of the postures that emphasizes muscles, stretching. Some examples of postures that may have contributed for these results are the sandwich (Paschimottanasana and Utanasana), dog (Adho Mukha), butterfly (Baddha Konasana), and snake (Bhujangasana). All these postures require the maintenance position and different muscle groups' stretching impacting the children performance.
No significant results were observed on the perceived competence and maternal and social acceptance results. Although previous studies highlight that yoga practice could promote the increase of self-perception and self-regulation of behaviors,,,, our study could not find support for these changes in behavior. However, some of the children thoughts illustrate well a couple of changes in self-perception and self-improvement (please refer to Speech 5). It is important to notice that self-perceptions are hard to be changed in a short period of time, may be an extensive program would detect more convincing changes related to this parameter.
The children's interest in continuing the practice of yoga after the end of the program, as well as the appreciation, and the spontaneous participation in the lessons, observed in this study, has been previously acknowledge in the literature.,,,,, Furthermore, the feelings expressed by children [Figure 3] and children discourses] corroborate with the literature suggesting that yoga practice can promote self-observation and self-knowledge in children.
The achievement of a greater command and control of emotions and calm feelings in nonpleasant experiences, reported in literature,,, were also observed in the children discourses (refer to speeches 3, 4, 5, and 8). The children's thoughts show that the yoga program helped them learn how to deal with emotions, and adapt to face and encounter challenging situations without suffering, interesting acknowledgment demonstrated by children in this study at young age.
In addition, improvements in social interactions (refer to speech 7) and reflection about health-related values were also reported (refer to speech 10), similar to the previous study. The literature also supports that yoga could contribute in reducing the levels of stress and anxiety in children,,, which was clearly noticed in children's interviews (refer to speeches 1, 2, 4, and 9).
Previous studies suggest that yoga practice could contribute in increasing social acceptance, communication, and contributions in classes,, result also observed in children's interviews. The speeches 7 and 9 were very strong in expressing these feelings. Children reported that after the yoga program they start to play with friends more often, felt more intelligent and well behaved in the class. The yoga practice for children seems to have a significant impact on general well-being,,, resulted confirm in this study.
Ultimately, the benefits reported in children, in this study, are similar to the findings for adults. Our results supported that yoga practice is very suitable for the school environment, serving as an educational intervention that promotes development and health for children, as previously suggested., It could also contribute for the well-being of children's future  if constantly included in the curriculum program.
The limitations of the study were the short period of intervention that was limited by the school board of education, the small sample size since it was an automatic choice for children, and also the lack of a control group. Further studies are necessary to detailed determine the changes that a yoga program can generate for school-age children, considering the educational values of this practice.
| Conclusion|| |
Based on the results of this study, we suggest that a 12-week yoga program promoted positive effects on the development of motor and physical parameters of children, especially on balance, strength, and flexibility. The yoga practice although in a short period was also efficient in generating positive well-being and social interaction. The results contribute in recognizing yoga as a potential education tool for a full and lasting development of children. It is also important to highlight that the practice of yoga for children must be developed in a playful manner and covering all aspects of child development.
