Introduction
The acquisition of a better quality of life results from several factors, such as the food system, social and cultural norms, and family environment. Some factors involve regulatory and commercial aspects that shape the food system and define the availability and accessibility of food1. In this sense, a significant relationship between consumption of ultra-processed food and weight, body mass index (BMI), and the abdominal perimeter has been evidenced2. Another factor that conditions the quality of life is the social and cultural norms concerning physical activity, including the built environment in cities; these environments typically restrict physical activity possibilities1.
Indeed, a study by Álvarez et al.3, concluded that people's perception is that the environments, due to environmental barriers, do not favor the practice of physical activity. Besides, avoiding low energy-cost activities, such as spending a long time sitting, should be recommended for the population's physical activity guidelines4. In addition to the factors already mentioned, the family environment is another variable that conditions a good quality of life. In this sense, the family plays a fundamental role as a model in the formation of the individual5. The last two factors (socio-cultural norms and family environment) may condition the population's quality of life and lead to high sedentarism levels. This latter condition increases cardiovascular and metabolic risk factors4.
In Chile, levels of sedentary lifestyles are above 80% in most age ranges; it ranks second among the countries with the highest prevalence of obesity6,7. Furthermore, it has been estimated that 34.4% of the population over the age of 15 is obese8. Likewise, some studies have estimated that by 2030 deaths attributed to obesity will exceed 200,000 and life expectancy will decrease9. These facts are the reason why the educational community and the social environment of children and adolescents must make a great effort to create and promote physical activity habits as soon as possible; thus, there will be a greater probability of generating an active life in adulthood10. In addition to the physical benefits of physical activity during childhood, there are also economic aspects that benefit from this practice; a sedentary and obese population represents a high economic burden for the individual and society9. In addition, physical activity has been shown to bring socioemotional benefits, which could turn into positive physical habits. If these positive effects are experienced during childhood and youth, the individual will continue a healthy lifestyle into adulthood11.
To achieve an active and healthy life, the World Health Organization declared that children and young people from 5 to 17 years old should spend at least 60 minutes a day in moderate to vigorous physical activity; besides, more time investment will bring more significant health benefits12. However, it has been shown that over 86% of the population in Chile does not engage in regular physical activity; this proportion is even higher among women and people of lower socioeconomic status13. Also, most populations have a low energy expenditure in their work-related activities14; besides, most of the population, especially children, spend two or more hours a day watching television or playing video or computer games15.
Therefore, parents play a very relevant role in this stage since they are considered the first influencers for young people16. In this sense, some studies have shown that there is a strong relationship between the physical activity developed by parents and the acquisition of physical activity habits by their sons and daughters; more specifically, adolescents with more physically active parents were more physically active than peers with less physically active parents17. Similar results have been found concerning the influence of coaches’ behavior on athletes (aspects such as athletes' well-being18, and abandonment of the sport)19. Therefore, a study by Sánchez et al.20, concluded that amusement during practice generates more adherence to sports, and decrease premature sport abandonment. Likewise, intrinsic motivation in the practice of physical exercise is a crucial factor to ensure active participation in physical habits21, producing more opportunities for socialization and greater psychological and physical well-being in people.
The influence of the affectivity of the environment on adolescents' physical habits is fundamental, especially at development ages22. It is very important that adolescents know how to react to the feelings and emotions of their age23. Besides, there is a positive relationship between the practice of physical activity in a child and the perceived positive emotional effects; this positive relationship is evidenced in improved self-esteem, reduced anxiety, and stress24. To this end, the aim is to reinforce the child's positive attributes and diminish the negative ones, knowing first the children's emotions, taking into account various socio-environmental factors25.
Within these socio-environmental factors, we can mention the work of self-confidence and self-efficacy in children and adolescents, being these fundamental aspects to carry out successfully a task26. Activities of this style will allow to work and to act in specific emotional scenarios of the adolescent, such as: not to ignore its feelings and emotions; to maintain a constant enthusiasm to carry out activities; and to control and to know how to handle states of unhappiness and sadness, situations of lack of interest, discouragement, and boredom27.
Over the last decades, the number of children and adolescents with obesity has increased tenfold worldwide, and 60% of the world's population is not physically active enough to obtain health benefits12. Thus, physical inactivity and obesity have been declared a worldwide epidemic28. As a result of this, generating physical habits in adolescence is vital to generate an awareness of this problem29.
Simultaneously, it has been demonstrated that an adequate support system together with social connection with the adolescent favors the experience of positive affective states. This creates a better emotional management in the individual, contributing to their self-confidence and self-efficacy30. It is essential to achieve adherence to physical habits31 due to the positive correlation between exercise habits in children and adolescents with active adult life32. Consequently, creating healthy habits is of great importance to reduce sedentarism and obesity; recognizing various social strategies could encourage the development of physical habits and thus improve health6. However, to the best of our knowledge, there are no up-to-date studies that reliably present the various socio-affective agents that influence the physical habits of the adolescent population. That is why this systematic review's objective was to review and analyze previously published research that studied the influence of affectivity on adolescents' physical habits.
Materials and methods
The development of this systematic review was carried out through a thorough reference-oriented search in different databases and electronic search engines: Web of Science (WOS), Scopus, and Scielo. The search limits were articles published between January 2010 and April 2020.
Databases
The literature search was conducted under the guidelines for systematic reviews and meta-analysis (PRISMA)33. In each of the databases, the title, abstract, and keyword search fields were searched. The following keywords were used in combination with the Boolean operators AND/OR: (["Affectivity" OR "Affective Behaviour"] AND ["Sport" OR "Recreational Activities"]). Two authors conducted the search and reviewed the studies; both decided whether the inclusion was appropriate.
Inclusion and exclusion criteria
The studies included in this systematic review were experimental studies published in the last ten years. Each study's importance was evaluated under inclusion criteria regarding their research design in population, intervention, comparator, results, and language. Studies had to be focused on teenage students in the educational system and on affectivity or affective behaviors on adolescents' physical habits.
They also had to compare various sports or recreational activities and approach results from the benefits or disadvantages of affectivity over sports practice in adolescents. Studies had to be published in English, Spanish, French, or Portuguese. The exclusion criteria were editorial documents, expert opinion essays, and papers not related to physical education, school, adolescents, or affectivity. Studies that did not meet the inclusion criteria were not considered in the systematic review. Both the articles' inclusion criteria and the discrepancies found were resolved by consensus between the two researchers who were part of the systematic review.
Results
The search strategy was divided into five stages. Stage one: electronic search in different databases, identifying 65 articles. After deleting all duplicates (18 articles), 47 articles remained. Stage two: Title and abstract filtering. After deleting articles by the exclusion criteria (41 articles), six articles were left. Stage three: Comprehensive analysis of the six articles. After reviewing the six articles, three were eliminated because they did not meet the inclusion criteria. Stage four: search for articles guided by the bibliography. No new studies were included in this phase. Therefore, the total number of studies for the systematic review was three articles (Figure 1).
The methodological quality of the selected articles
It was used the Physiotherapy Evidence Database (PEDro) scale34,35 to evaluate the studies' quality. The classification was based on three criteria: selection (maximum three stars), comparability (maximum three stars), and results (maximum four stars). Articles with scores from eight to ten were considered as high methodological quality. Those with scores from four to seven of moderate quality and those with scores below four were considered low quality.
The items on the PEDro scale are 11: (1) eligibility criteria were specified; (2) subjects were randomly allocated to groups; (3) allocation was concealed; (4) the groups were similar at baseline regarding the most important prognostic indicators; (5) there was blinding of all subjects; (6) there was blinding of all therapist that administrated the therapy; (7) there was blinding of all assessors who measured at least one key outcome; (8) measurements of at least one key outcome were obtained from more than 85% of the subjects initially allocated in groups; (9) all subjects for whom outcome measurements were available received the treatment or control condition as allocated, or where this was not the case, data for at least one key outcome were analyszed by "intention to treat"; (10) the results of between-group statistical comparisons are reported for at least one key outcome; (11) the study provides both point measurements and measurements of variability for at least one key outcome34.
The score obtained by the articles, according to the PEDro scale, indicates that three studies obtained a high score (Table 1).
Within the three selected studies, independent of the type of socio-emotional support, sex, age, body mass index, all three presented significant results in the influence of affectivity30,36,37 (Table 2).

Discussion
At the end of the systematic review, several affective situations were found to influence adolescents' physical habits38. These studies focused on analyzing the importance of affectivity for Physical Education classes, as well as the relationship between affectivity and the presence of obesity, gender diversity, and the development of physical habits22. Simultaneously, it was observed that the correct planning of a Physical Education class could directly influence the students' integral development and generate a greater interest in physical activity. The latter could also increase self-esteem and motivation towards physical habits, decreasing overweight and obesity37.
Another finding of the systematic review was the influence and stability generated by a correct relationship with the family and the training coach, directly affecting the adolescent's sports adherence and performance30. Some studies also reported differences in the students' ages and genders, demonstrating different interests and tastes36. These findings allow us to observe the influence that affectivity has on the habits of physical activity, physical exercise, and sports, which improve the population's quality of life.
Affectivity as cause and effect
Affectivity can be analyzed from two different perspectives: as a cause (positive and negative feelings towards physical education classes) and as an effect (positive or negative emotions as a consequence of the class). From a causal standpoint, the most effective learning occurs when learners have positive emotions, are engaged in the class, and are not stressed. Research establishes that information is more likely to be fixed in long-term memory when it is relevant to the learner3.
Motivation is another positive feeling towards classes; according to research, its levels are connected to class engagement39. Students with intrinsic motivation are authentically engaged to practice learning in behavioral, emotional, and agentic dimensions40. There is also evidence that other positive feelings, such as character strengths, become crucial for students' school functioning and their overall school achievement41. On the other hand, negative emotions towards the class have negative learning consequences. Stress prevents the information storage process42, which is a feeling that comes from very different sources (conflicts, life changes, pressure, among others)43. Besides, the lack of motivation decreases as the school level increases39; therefore, adolescent students become less motivated than children. There are also psychosocial factors involved in student participation; fear, embarrassment, social isolation, judgment, and discrimination are barriers to participation44.
From the effect perspective, positive emotions that are caused during a class can be very motivating for students. Teachers' instructional practices have shown significant relation to student motivation45, and students have a positive perception when teachers communicate their feedback verbally46. Some negative emotions that may arise at school are: anxiety (connected to changes in adolescent school transition47; self-defense and reduced attention48; and ‘embarrassment evaluation’ (loss of self-esteem over task failures) and ‘embarrassment as exposure’ (individual thinking that others are monitoring them)49, among others.
Considering that external influence at school may promote positive emotions and that these emotions may predispose students towards a better class outcome, it is recommended that teachers promote a supportive environment for their students. Promoting positive emotions and a supportive school environment will contribute to students’ well-being50. It is recommended, from a neuroscientific approach, to: arouse students' curiosity and interest, counteract stress, boredom, and frustration, defuse undesirable behaviors, incorporate motivating goal-game learning (achievable challenges, predictions, and permanent feedback) break through stereotypes, and develop students' executive function skills (such as focus, prioritization, organization, collaboration, critical analysis, and innovation). The brain converts a vast amount of sensory input into long-term memory and durable understanding42.
Positive and negative affectivity present in Physical Education classes
Students show very varied emotions from the cause perspective due to the affective influences present in Physical Education classes; vitality and being physically active are the variables that contribute most to positive affectivity30. In turn, feelings of stress, fright, shame, and agitation are the most significant negative affectivity, especially in girls23,51. Contexts for experiences of body-related embarrassment primarily include school and sports or physical activity settings; it connects to fear of negative evaluation, social comparisons, body exposure, and inadequacy compared to an internal standard51. From the effect perspective, to increase positive affectivity, teachers should use these results to design and develop classroom intervention programs, considering the emotional characteristics of students52. In this way, one could ensure adherence to physical activities and sports practices in the future, consolidating a healthy lifestyle29. Also, in Physical Education classes, positive feedback has predicted greater intentions to participate53. In this sense, the tendency is to decrease the adverse effects and increase the positive ones54,55.
Influence of the coach on the motivation of the athletes
Some precedents associate greater amusement in the game with greater adherence to sports practice20. In this regard, the motivational climate created by coaches within youth sports teams is of great importance to the quality of young people's sports experiences56. Regarding the latter, Ruiz et al.57 tested a motivational model in the sport context via structural equation modeling. These researchers concluded that the perceived task climate emerged as a positive predictor of satisfaction of all three psychological needs; in contrast, the perceived ego climate was a negative predictor of relationship satisfaction. Consequently, the coach's motivational climate implications are discussed in light of its implications for the quality and potential maintenance of sports participation among athletes57.
Simultaneously, Curran et al.58 examined the mastery climate (emphasis on effort and learning) and performance climate (emphasis on ability and outcome) in adolescent soccer players; at the end of the research, the authors reported that a mastery climate positively predicted all dimensions of engagement. Besides, the cognitive aspects of engagement were positively predicted by climate performance. These same researchers concluded that a mastery climate offers a means to promote higher levels of overall participation58.
Also, Møllerløkken et al.56 directly compare players' and coaches' perceptions of their respective teams' motivational climate. At the end of the study, the researchers noted that players of both sexes perceived the motivational climate to be significantly more performance-oriented and significantly less dominance-oriented than coaches, concluding that understanding player motivation is important to the persistence interruption of the sport. As observed, both the motivational climate and the orientation of sports practice condition the participation or abandonment of the sports practice20,56. In turn, coaches' motivational strategies should be reviewed, as there is sometimes a mismatch between the motivational strategies used and those perceived by young people in sport56.
Impact of physical habits on obesity
Evidence shows a more significant presence of positive emotions in normal-weight students; negative emotions are mostly present in students with overweight or obesity problems37. Specifically, it has been described that there is a relationship between the presence of obesity and negative emotional states, such as high levels of anxiety, depression, lack of satisfaction in body image, and low self-esteem25,59. Besides, there is a relationship between obesity and psycho-emotional discomfort, conditioning the satisfaction level in life60. In this context, it is clear that there is an urgent need to educate these aspects to a society that repeats unhealthy behaviors6. Therefore, the problem is the person who suffers from obesity and a whole social nucleus that does not have these healthy habits rooted61,62.
This fact demonstrates that the human being develops learning by imitation; therefore, it is extremely important to consider the adolescent and his whole environment15. As already mentioned, the quality of life is conditioned by several factors; in this sense, food regulation and commercialization define the availability and accessibility that families have to these products1. Therefore, if the consumption of ultra-processed foods generates increased body weight, body mass index (BMI), and abdominal perimeter2, it may also generate negative emotions in students37. In turn, social and cultural norms, including the built environment in cities, condition the level of physical activity of the population1, in turn, environmental barriers influence the physical activity behavior of the school population3. In this sense, some research has pointed out that sports facilities that are often insufficient and precarious for the practice of physical exercise and sport63.
When mentioning the factors that condition the levels of overweight and obesity in children, and by association the quality of life and the children's emotions, the family environment stands out as one of the main responsible1. In this sense, the family has an essential role in the formation of a person5. Research by Latorre et al.63 concluded that most parents initiate their children into sports for the health, education, fun, and socialization that comes with playing sports. The same researchers mention that parents are important enough to create the right habits63.
As it has been observed, there is an association between abnormal anthropometric parameters with adverse effects on emotions37. It has also been determined that low levels of physical activity are a priority factor in the development of overweight and obesity2. Likewise, it has been reported that parents are the primary agents in creating the habits of physical activity, physical exercise, and sport63. Therefore, all these factors condition the quality of life of the child population. These factors should be considered in governmental policies globally; it has been demonstrated that children manage to perceive environmental barriers (physical, social, institutional) as agents that affect their physical activity levels3.
Socio-emotional support on experienced affectivity, self-confidence, and self-efficacy in young people
It has been demonstrated that adolescents configure their personalities through their emotional experiences in the family, school, and society that most affect their development64. However, educational practice has hardly valued the importance of affectivity in acquiring an integral formation65. Considering that education must be oriented to the full development of the student's personality, cognitive development must be complemented by emotional development31. In this emotional development, the family and the coach have a fundamental role, finding a good correlation between the favorable climate, the support in the autonomy, and the emotional development (r=0.55 and r=0.36, respectively)30. Besides, these safe and positive social models encourage more resources and skills for decision making and problem-solving66 and better manage stressful situations67. This leads to young people developing holistically, with cognitive, physical, and emotional education27.
Different achievement goals according to age and gender
Evidence shows that there are more significant positive effects in the study groups 10-12 and 15-17 years old when the assigned activities are related to the task and friendship approach. In turn, the group of 13-14 years old presents positive effects in the approach and avoidance of the task, while in the range 10-12 and 15-17 years old there are adverse effects in the approach to the task; finally, in the ranges 13-14 years old the most significant adverse effects are presented by the approach of friendship36. On the other hand, several researchers have shown that men are continually comparing improvements among pairs, more than women23,59,68. However, there are contrasts with other studies in which Korean students from the age of 12 onwards adopted greater affection in the approach-performance goals69. This information allows us to observe how the socio-cultural context directly influences the students' adoption goals68.
Limitations and perspectives
Undoubtedly, a systematic review including three articles does not allow us to generalize the results. However, this scant evidence analyzing the influence of affectivity on school children and adolescents' physical habits is an indicator of two conditions. On the one hand, despite the evidence showing the importance of physical activity, physical exercise, and sports in people, the influence of the environment on school children and adolescents' physical habits has not been assessed. On the other hand, the adult population, unaware of this influence, generates a vicious circle that triggers sedentary adults with low quality of life. We believe that this study contributes to future research on affectivity as a determining factor in the acquisition of physical habits in children and adolescents.
Conclusions
At the end of the systematic review, it was shown that there is a significant influence of affectivity on adolescents' physical habits. Also, it could be observed that this influence, whether positive or negative, will directly influence adolescents' interest in physical activity and sports, conditioning their adherence to sports practice in adulthood.
Although there are positive and negative affective situations throughout life, adolescents must have the necessary tools to face various situations of fear, surprise, anger, joy, and sadness that may arise. These situations can be better addressed if adolescents have a network of constant social-emotional support, mainly family, teachers, coaches, and friends. Likewise, if these interactions are correct, they generate in the student greater self-esteem and self-confidence.
Finally, although they are not the main factor, it is also crucial that there are physical spaces that encourage adherence to these practices for the incorporation of physical activity habits. The spaces designed for the practice of physical activity should be in all environments of children and adolescents (schools, squares, recreation centers, among others).
Practical Applications
In practical terms and after conducting the systematic review, we recommend taking the following considerations to generate greater adherence to physical habits:
Physical Education teachers should consider the diversity of each student's characteristics, thus developing activities that generate class's enjoyment and encourage the development of a positive attitude, generating an integral development in their personality.
Physical Education teachers must integrate the entire educational community to promote physical and healthy habits, including directors, parents, and guardians.
Coaches must consider athletes' autonomy, which will provide tools for developing their self-esteem and self-confidence, increasing their ability to overcome any adversity.
