Emotional Self-Regulation through Introjective Practices in Physical Education

This study analyzed emotional self-regulation in relation to K-9 and K-10 school children’s emotional intelligence defined on three dimensions: Emotional attention, clarity of feelings, and emotional repair. The objective was to analyze the students’ perceptions of skills and capacities that promoted the awareness of emotions when performing introjective motor practices, i.e., motor skill exercises in which the inner logic provokes a process of sensorial self-awareness and psychosomatic balance. A total of 90 fourth-year primary school students from four different schools participated in the study and a reduced version of the Trait-Meta Mood Scale (TMMS) questionnaire was used to measure students’ individual self-regulation. First, preand post-test results showed significant differences with a 20.1% improvement in the three dimensions of intrapersonal emotional attention (emotional attention, clarity of feeling, and emotional repair) after having performed a set of in-class introjective practices. Second, while there were no significant differences between the boys and girls during the pre-test, significant changes—an 8.1% difference—were found in the post-test results for girls.


Introduction
One of the main educational purposes of schools is to guarantee the overall development of individuals, preparing them to be able to cope with social demands. In recent years there has been a sharp growth in practices focusing on improving young people's health [1] and developing emotional competences, as well as self-awareness and emotional regulation [2][3][4][5]. Different authors have established specific areas and contents to ensure that the purpose of primary education (PE) is to provide children with the competences that will enable their personal and social development [6]. The education system must provide emotional education which helps the individual develop good socialization skills and the emotional competences that will enable them to enjoy personal well-being [7].
Emotions are an undeniable and integral part of a human being which condition physical and mental health while also playing a key role in behavior, learning, and interaction with others [8][9][10]. Furthermore, a link is established between what we feel and our control over our thoughts and behavior in such a way that we experience different emotions on a constant basis which, in turn, influence our actions [11,12]. In view of this, numerous authors highlight the importance of becoming aware of our own emotions and putting a name to what we feel [13,14]. For this reason, it is vital to provide individuals with emotional education.

Participants
The sample was comprised of 90 fourth-year PE students, with a mean age of 9.5 years, with 40% (n = 36) being boys and 60% (n = 54) girls. Students were split into four classes from four schools and, since the characteristics of the schools matched our research interests, all groups were considered as one single convenience sample. In addition to the researchers, eight primary school teachers also participated in the study; four PE specialists and four fourth-year general education teachers (n = 8; aged between 26 and 36 years old; M = 32).

Ethical Considerations
The entire research process was carried out with the prior authorization of the teachers and students involved. All the participants were informed of the objectives of the study, as well as the conditions for participation. The use of data took into account ethical principles and ensured anonymity. This study was approved by the Research Ethics Committee (REC) of the University of Girona in 2019.

Procedure
The study was structured into three phases (Table 1). In line with Cañabate et al. [34], the aim was to create a specific classroom climate to motivate students to participate in the practices developed during all phases of the research project. In this way, intrinsic motivation and task organization were closely linked to a motivational climate focused on the task at hand [20]. It is important to remember that classroom climate is an essential element that predisposes and determines social relations within the teaching and learning process (Sánchez et al., 2016). In the first phase, the whole program was explained to the students, including the set of six introjective motor practices, and the Trait-Meta Mood Scale (TMMS) questionnaire [35,36] was presented.
In this first phase (Week One) the TMMS questionnaire was distributed (pre-test treatment). In the second phase, classes were devoted to putting into practice the six introjective practices: Yoga, Tai Chi, eutony, active global stretching, Qi-gong, and corporal dance expression ( Table 1). The intervention phase of this project was carried out in PE sessions four days a week, therefore, the intervention lasted for a full six weeks. Each of the introjective practices was linked to the physical education objectives as defined in the Spanish curriculum for the middle cycle of PE (Table 1) and to a set of specific competences (Table 2), and also to the assessment of physical activity in relation to health and well-being, and/or the development of expression of emotions and feelings through the body, gesture, and movement, which are at the very core of promoting the development of personal well-being and emotional intelligence. In the third phase (Week Eight) the TMMS questionnaire was distributed (the post-test treatment) and the results were discussed between the primary school students and their teachers.
During the six intervention sessions, students followed a ritual upon entering or exiting class. The ritual on entering consisted of four minutes of silence, in which students relaxed, and which also helped to create a suitable climate for starting the class. Likewise, a ritual for leaving that consisted of reflecting on how the class had gone, what new experiences or emotions they had experienced, and/or any anecdotes they wanted to share with their peers was also included. Table 1. Definition of the six introjective practices, and the associated physical education objectives.

Introjective Practices Physical Education Objectives
Yoga (PE1): A technique that improves psychological and cognitive parameters as well as sports performance. Reduces symptoms of perceived stress, worry, depression, and increases the state of mindfulness. Greater awareness of the musculature is also observed after performing conscious breathing techniques and paying attention to the parts of the body.
Tai chi (PE2): A technique used to improve the physical, mental, and spiritual quality of life. Tai Chi is a type of movement meditation, where the person who practices it is focused on the here and now.
Work on own movements that form representations of nature.
Eutony (PE3): A discipline based on the experience of the body itself, which leads the person to become aware of themselves.
Develop awareness in order to be conscious of the increase and decrease in muscle tone.
Active Global Stretching (PE4): A variant of global postural re-education. It is an effective stretching technique for preventing or improving injuries, as well as improving muscle performance.
Develop balance exercises and muscle synergy. Perform progressive stretches to affect muscle tone in particular.
Qi-gong (PE5): This is a discipline that improves the regulation of anxiety, depressive symptoms and self-efficacy. Its goals are to improve health, relieve pain, eliminate stress, anxiety and depression, and help to have more energy and vitality.
Use breathing techniques through moderate physical exercise. Combine breathing and body postures.
Corporal Dance Expression (PE6): This is a discipline that improves the motor behaviour of the individual with an expressive, communicative and aesthetic purpose. It is based on the development of movement with attention to the feelings of the individual.

Recognize the body as an instrument of expression and communication. Work on communication through body language.
Reflect on expression and communication activities with the intention of improving communication. Table 2. Physical education competences that are linked (blackground in grey) to the six introjective practices (PE1 to PE6).

Introjective Practices PE1 PE2 PE3 PE4 PE5 PE6 Physical Education Competences
Adequacy of consciousness and control of the body in relation to tension, relaxation, and breathing. Discovery of organic and functional elements related to movement. Experimentation with the body and movement. Adaptation of movement to spatio-temporal structures.
Valuation of one's own bodily reality. Assessment of physical activity in relation to health and well-being. Use of laterality in relation to one's own body, the bodies of others, and other objects. Use of static balance and dynamic balance in different situations.
Resolution of the structure of space and time in motor actions and situations. Perception of effort during physical activity. Expression of emotions and feelings through the body, gesture, and movement.

Instrument
The TMMS-24 is a version of the Trait-Meta Mood Scale (TMMS) developed by Salovey et al. [35], which was reduced, validated, and adapted into Spanish by Fernández-Berrocal et al. [13]. The TMMS-24 has been used as it is a specific instrument for analyzing students' emotional experiences (Table 3). It contains three extremely important dimensions for intrapersonal emotional competence, each of which included eight items (24 items in total): Emotional attention (the perception of emotions), clarity regarding feelings (the inner understanding of feelings), and emotional repair (the regulation of emotions), which can be defined in the following way [35]: Emotional attention: The person is capable of feeling and expressing their emotions and feelings in an appropriate way. Emotional perception refers to the capacity to consciously recognize one's own emotions, to identify them and put the appropriate name to them.
Clarity of feelings: The person is fully aware of their own emotional feelings. Emotional understanding allows us to integrate what we feel into our thinking and to be able to consider the complexity of emotional changes.
Emotional repair: The person is able to regulate their emotional state correctly. Emotional regulation consists in managing both positive and negative emotions efficiently [13]. This aspect is closely related to resilience, a concept that currently attracts considerable attention insofar as it helps to reinforce the training of school children and sports people [37].
Participants were asked to score each of the items on a five-point Likert scale, from never (1), rarely (2), sometimes (3), fairly frequently (4), to very frequently (5), for each of the component scales. Answers to items 1 to 8 were added together to obtain the mean results for the emotional attention scale, likewise for answers to questions 9 to 16 providing information on emotional clarity, and answers to questions 17 to 24 in relation to emotional repair (Table 3). SPSS 21 ® software was the statistics analysis tool used for the data. The database was entered onto a spreadsheet, and subsequently analyzed. Reliability of the questionnaire was obtained with the total of 90 samples. The reliability of each component of the TMMS questionnaire based on the calculated Cronbach's alpha for the three group categories for the post-test analysis (Phase 3) was α = 0.83. In addition, the test and retest reliability was appropriate since for the initial test (Phase 1), the Cronbach's alpha for the three group categories was calculated to be α = 0.82. The values to understand reliability are: < 0.60; 0.60 ≥ uncertain < 0.70; 0.70 ≥ acceptable < 0.80; 0.90 ≥ good < 0.90, and α ≥ 0.90 excellent, the experimental Cronbach's alpha for the pre-and post-test treatments ensured that the TMMS presented an excellent internal-consistency reliability.
Data for the pre-test and post-test treatments and for the overall (pre-test + post-test) were tested for homogeneity and normality. The post-test and pre + post-tests met these criteria, whereas the pre-test data had to be transformed as pre-test 1/4 . A two-way ANOVA with replicates was performed for the pre-test, post-test, and overall, with the aim of finding differences between treatments and gender.

Results
There were significant differences between the pre-test and the post-test (<0.010) for the analysis of gender during the application of the treatments ( Table 4). The mean range for the three dimensions of the TMMS for the pre-test were 2.96 for emotional attention, 3.03 for clarity of emotions, and 3.05 for emotional repair, with a total mean of 3.03 ± 0.47 ( Table 4). The mean range for the three dimensions of the TMMS for the post-test were 3.53 for emotional attention, 3.67 for clarity of emotions, and 3.72 for emotional repair, with a total mean of 3.64 ± 0.48 (Table 3). Therefore, a difference of 20.13% was found for the overall pre-test and post-test mean results.
The highest differences between the pre-and post-test, in the dimension of the perception of emotions, i.e., emotional attention (Table 3), were obtained for question 8 (I pay a lot of attention to the way I feel), with a 26.0% difference, question 5 (I allow my feelings to affect my thoughts), with a 23.7% difference, and question 2 (I am usually very conscious of what I feel), with a 23.0% difference. In the dimension of clarity of feelings, referring to the inner understanding of feelings (Table 3), the highest differences between the tests were obtained for question 14 (I can always say how I feel), with a 35.8% difference, question 16 (I can manage to understand my feelings), with a difference of 23.5%, and question 15 (I can sometimes say which emotions I am experiencing) with a difference of 21.9%. And finally, in the dimension of regulation of emotions, i.e., emotional repair (Table 4), the highest differences were observed for questions 18 (Even when I feel sad, I try to think about pleasant things), 21 (If I think about things too much and end up complicating them, I try to calm myself down), and 20 (I try to have positive thoughts even when I feel bad) with differences of 27.4%, 27.1%, and 26.2%, respectively.
The analysis also included information on differences with regard to gender for both pre-test and post-test treatments. In this case, significant differences were found between girls and boys for the post-test treatment (p = 0.007). For the post-test treatment, girls scored a mean of 3.76 and boys a mean of 3.48 (Table 5), with a total difference of 8.05%. The results of the one-way ANOVA separated for girls and boys for the post-test treatment are presented in Table 5. The interaction between the gender dimension and the treatments were not significant (Table 5).

Discussion
The main objective of this study was to gain knowledge on emotional education through implementing physical education introjective practices to help primary school students become more aware of their own emotions, to identify them and, consequently, to be able to manage them. Attention was focused, in particular, on the development of the socio-emotional or socio-personal competences that help promote self-knowledge and the self-regulation of emotions (Goleman, 1995). Results showed that the intake of emotional competences was balanced by the perception of emotions, the inner understanding of feelings, and the regulation of emotions. The educational approach based on the implementation of introjective practices largely impacted the primary school students on emotional attention, with students paying a lot of attention to the way they felt and also to the clarity of feelings, with students explicating that by carrying out the introjective practices, they can always say how they feel. In particular, this question was the one that produced the highest differences of 35.8% after applying the practices. Finally, in terms of emotional repair, students highly scored the questions relating to how the introjective practices make them think about pleasant things, have positive thoughts, and help them to calm down. Therefore, applying introjective practices to a physical education class might be an approach for stimulating self-awareness processes in primary schools that enables individuals to achieve emotional self-control. These results align with many other recent studies that report educational practices promoting emotional regulation [1,11,12,27,28].
In view of this, the results here report significant changes regarding emotional regulation. In this sense, and following the theoretical approaches referred to, children first learn to identify their emotions by becoming aware of the present moment and, as a result, they gradually acquire the skills that enable them to have greater self-control [26,29,31]. The significant differences between the pre-and post-tests, as well as our observations of the approach, showed that the practice of mindfulness in educational practice helps students to identify and become aware of the emotions they feel, with this being the first crucial step towards being able to manage their emotional states. As a result, the implementation of introjective practices in physical education in schools can be used as a tool to develop emotional education with the appropriate guidance of the teacher.
Along these lines, the results obtained in this study through the three dimensions of emotional attention, clarity of feelings, and emotional repair provide interesting and relevant data, as discussed above. Likewise, the changes produced at the end of the intervention and recorded in the instrument used are a direct consequence of the educational intervention or, in other words, of what has occurred between the pre-and post-test; i.e., the introjective practices carried out. Moreover, the findings of this study are similar to those found in other studies insofar as they show that the practice of paying full attention reduces levels of nervousness and stress [16] and, at the same time, produces positive post emotions [1,12,19,26]. The internal logic of this activity helped to reduce negative emotional states and, by contrast, to bring out enthusiasm or positive states of mind, as revealed by other studies [1,12,16,26].
Our investigation showed differences between the pre-and post-intervention by showing improvements in the attention dimension, with appropriate levels reached on completion of the project, as students were able to feel and express these feelings adequately. We also observed a significant result in the overall sample of girls after implementing the approach based on introjective PE practices, which means that girl students were highly aware of their emotional states, and these improved following the approach. The results obtained are in line with those of Extremera and Fernández-Berrocal [15], showing that with the practice of mindfulness, paying full attention provides an opportunity to become aware of one's emotions and therefore provides the tools needed by children to be able to control them, thus developing their personal well-being [1,26,27].
Nonetheless, this kind of introjective educational practice must be carried out over time and in a systematized way in order to produce changes in young people's attitudes [1,28], such as establishing a systematized practice at school to address emotions, with more systematic work and a specific time and space throughout the whole school year to be able to help students self-regulate their emotions. In view of this, and according to Flook et al. [28], undertaking a task such as mindfulness is like learning to play an instrument or a sport; it requires both time and dedication.
The conclusion of this study shows how introjective practices provide primary school students with the tools with which to face the different problems they encounter in their daily lives, whether these are of a motor-based or emotional nature. The practices thus help to better understand their body and to control it without it controlling them, on the basis of the emotions they feel. In this sense, the practice of mindfulness can help achieve this goal, and as PE is conceived as a cross-disciplinary subject it provides an ideal space in which to achieve this.

Prospects and Limitations
We believe this article may be of interest to primary school teachers, since it helps reflect on the effect of introjective practices in the development of emotional self-regulation, verifying the existence of improvements between the before and after stages of educational intervention. This study therefore provides useful information for teachers, and specifically PE teachers, effectively promoting their motivational strategies towards a practice focused on the self-regulation of the emotions.
It is important to point out that this study has some limitations, such as the use of one single instrument in the form of the TMMS questionnaire. As such, future studies could consider widening the sample size and using other emotional competence scales to compare the results. The use of an instrument that only collects quantitative data also presents a clear limitation and future studies could use mixed methods, employing other instruments such as reflective diaries, to obtain qualitative data that would enrich the interpretation of the results. These kinds of studies should help to establish practices promoting full attention in a systematized way in schools throughout the entire school year, to help students become more aware of their emotions, using different resources to help students control them, and develop forms of emotional self-regulation that contribute towards their personal well-being.
Taking into account the results obtained and the objective established at the outset, we can state that significant improvements can be observed in students' levels of emotional regulation. Although this study has provided students with a significant step towards self-regulation, the limitations of the study mean that these results and conclusions have to be linked to any approach to physical education that fosters cognitive, motor, and emotional competences. That is, although this study presents the link between introjective practices and the emotional self-regulation they provide, no information was planned for or tested in terms of knowledge acquisition or promotion of motor competences. A key area would be to determine which introjective practice produces either cognitive, motor, or emotional competences. This could be attained by reformulating the whole approach with an entirely different process of assessment and evaluation.
