1 INTRODUTION
Systematic reviews establish that physical activity performed by children with disabilities is less practiced than people without disabilities (Jung et al., 2018; Li et al., 2016). A meta-analysis identified that physically active students of school-age with hearing impairment have a better quality of life than students with a sedentary lifestyle (Kitterick et al., 2015). It has been reported that only 20% of boys, girls, and adolescents with hearing impairment comply with the recommended quantity by the World Health Organization (WHO, 2010), being 60 minutes daily of moderate to vigorous physical activity (Li et al., 2019). Research in basic education that has assessed the physical activity of students with hearing impairment reports sedentary behaviors during the school day (Sit et al., 2007; Sit et al., 2019), which is unfavorable for this section of the population, due to the etiological nature of hearing impairment; which partially or limits hearing in one or both ears (Franco & Panhoca, 2008), which generates poor motor skills with low levels of coordinative physical capacities (Jafarnezhadgero et al., 2017; Rajendran & Roy, 2011; Walicka-Cupryś et al., 2014). Based on intervention studies in Physical Education, the practice of physical activity for motor skill development in students with hearing impairment has been widely recommended (Ochoa-Martínez et al., 2018; Ochoa-Martínez et al., 2019).
Internationally, vigorous to moderate physical activity is considered part of the quality standards in Physical Education, for example, the National Association for Sport and Physical Education (NASPE) recommends Physical Education teachers promote the participation of moderate to vigorous physical activity in students for at least 50% of the total Physical Education class time (Baghurst et al., 2015). Regarding school recess, it has been identified as a time frame to promote the practice of physical activity (Baquet et al., 2018; Galbraith & Normand, 2017). Ridgers et al. (2011), reports that during recess time, students can reach up to 40% of the recommended daily physical activity.
Studies establish multiple factors in the school day that promote the practice of physical activity in students, such as infrastructure, available space, the educational model utilized, and the content direction of teachers (Chen et al., 2018; Hollis et al., 2014). Within the Mexican context, research during Physical Education and recess has assessed moderate to vigorous physical activity in students of school-age without the impairment (Hall-López et al., 2017; Hall-López et al., 2018). In this sense, the WHO (2011) refers in the World Report on Disability that the number of people with disabilities is on the rise. These are considered a vulnerable population with fewer possibilities than their non-disabled counterparts of entering basic education, staying in it, and enrolling in successive school years. Regarding physical activity of people with disabilities, it is reported that only 33.8% of schoolchildren with disabilities perform any sports or physical activity apart from Physical Education (Jung et al., 2013), according to our knowledge, we have not identified any research within the Mexican context that evaluates physical activity in students with hearing impairment, the above is important as a basis for action by teachers working in the field of Physical Education around people with disabilities (Andrade & Freitas, 2016) and have teaching-learning conditions with inclusive methods (Simões et al., 2018) since the United Nations Educational, Scientific and Cultural Organization (UNESCO), manifests in its guide for policy makers in Physical Education to focus inclusive methodologies aimed at raising awareness about people with disabilities, pro moting values during Physical Education class, and should also be regulated for promotion among students, parents, and members of the community (Mclennan & Thompson, 2015). Therefore, this research aims to comparatively determine physical activity during Physical Education class, and recess of students with hearing impairment in primary school.
2 METHOD
2.1 PARTICIPANTS
The research was authorized and registered in the Office of Graduate Studies and Research of the Autonomous University of Baja California and was approved by the Faculty of Sports. The studies were performed using a comparative descriptive cross-sectional method (Thomas et al., 2015), and were conducted in two educational institutions in Mexicali Baja California, Mexico; that offer specialized education for people with hearing impairment according to the International Classification of Functioning, Disability and Health (ICF) established by the WHO (2013), which has as criteria people with a total or partial deficit of perception that is evaluated with the loss of audio of each ear. Exemption from participation was requested from administrators, teachers, and parents, and following the ethical principles of research involving human subjects of the declaration of Helsinki, taking into account the participation of children and young people (Rupali, 2005).
2.2 INSTRUMENT
The universe was made up of 140 Physical Education classes that took place during the school year, in the two educational institutions that provide care for students with hearing impairment, 58 Physical Education classes and recesses were probabilistically evaluated with a margin of error of 10% and a confidence interval of 95%. To determine moderate to vigorous physical activity during Physical Education classes and recess, the System for Observing Fitness Instruction Time (SOFIT) was utilized as a measurement (Mckenzie et al., 1992). The SOFIT protocol evaluates teachers qualitatively and quantitatively, through four students (two men and two women) that represent the class. In total, 232 students enrolled in educational centers with an average age of 9.6 ± 2.9 years were evaluated (boys n = 116 and girls n = 116). The length of each Physical Education class was of 50 minutes. Each student was observed in a rotating sequence of twelve intervals for twenty seconds, repeating the observations throughout the class.
To record the activity, an audio player that indicates the recording time and the subject to be evaluated was utilized as a guide. According to the SOFIT method, five codes that represent the student’s physical activity following the teacher’s instructions were followed, the evaluator knew and memorized the operational definitions of the codes, which are numbered as follows: 1. Lying down, 2. Sitting, 3. Standing, 4. Walking, and 5. Very active, which corresponds to running, or activity with higher energy expenditure. The moderate to vigorous physical activity performed in class represents the percentage sum of codes 4. Walking and 5. Very active of the total time of the Physical Education class. According to the procedures of the SOFIT instrument, after the Physical Education class, the same students evaluated during Physical Education were assessed during recess, which lasted 30 minutes.
2.3 STATISTICAL ANALYSIS
For the statistical analysis, the Statistical Package for the Social Sciences (SPSS version 23) was utilized, determining the descriptive statistics and the percentage difference (Δ%) of physical activity of deaf and hearing-impaired students during the Physical Education class, and recess. As a cross-sectional study, when comparing fixed variables, these were divided into two groups, students with deafness and hearing impairment, having physical activity in Physical Education classes, and recess as random variables to calculate the equality of the variance. Parametric statistics were utilized through the Student’s t-test for independent samples, determining a level of α≤ .05, that is, 5% as a percentage of error of the statistical test.
3 RESULTS AND DISCUSSION
The research evaluated 58 Physical Education classes and recess of the first to sixth grades of primary school, with an average duration in minutes of 45.9 ± 7.1 and 30.7 ± 2.3 respectively. Table 1 presents the descriptive statistics of physical activity of the five codes evaluated by SOFIT: 1. Lying Down, 2. Sitting, 3. Standing, 4. Walking, and 5. Very Active.
Physical Activity | Physical Education | School Recess | ||||||
---|---|---|---|---|---|---|---|---|
M | SD | Rank | M | SD | Rank | |||
1) Lying Down (min) | 1.3 | ± | .4 | 0-2.1 | 1 | ± | .3 | 0-2.5 |
2) Sitting (min) | 5.9 | ± | 1.2 | 0-6.3 | 9 | ± | 2.8 | 0-1233 |
3) Standing (min) | 23.9 | ± | 6.2 | 9.3-29.7 | 7.9 | ± | 2.5 | 2.6-10.3 |
4) Walking (min) | 10.3 | ± | 2.1 | 3-10.6 | 7.2 | ± | 2.4 | 2-7.1 |
5) Very Active (min) | 4.5 | ± | .3 | 2-7 | 4.9 | ± | 2 | 1.1-6.4 |
The normality of the groups and the homogeneity of variance of the data were verified through the Kolmogorov-Smirnov test with a degree of significance of P-Value ≥ .05. The student’s t-test reported significant differences in moderate to vigorous physical activity in Physical Education with a percentage difference of 25.2 (Δ%) with respect to school recess (.001). The calculation of the equality of variance of moderate to vigorous physical activity can be observed in Figure 1.
The main result of this research was that the average values of moderate to vigorous physical activity, adding percentage codes 4 and 5, were higher during school recess than in Physical Education classes in students with hearing impairment. When reviewing the state of the art, a study that utilized the same methodological procedure through SOFIT evaluation in educational centers for the disabled also reports a greater moderate to vigorous physical activity in minutes during school recess of 8.9 and in Physical Education of 7.8 (Sit e t al., 2007). Within the Mexican context, according to our knowledge, only the results of research in educational institutions with students without diagnosed disabilities are reported, which reported similar patterns of moderate to vigorous physical activity with percentage averages during the recess of 50% and 41% in Physical Education in primary education students (Hall- López et al., 2017); and at the secondary level of 50% during school recess and 37.2% in Physical Education classes (Hall- López et al., 2018). Regarding the global practice of physical activity, the pattern coincides with studies that refer to less practice in children and youth with disabilities, compared to the population without disabilities (Jung et al., 2018; Li et al., 2019). In our research, the evaluated moderate to vigorous physical activity of students with hearing impairment was 32.2%, which when compared with those internationally established by the National Association of Sport and Physical Education (NASPE) does not achieve moderate to vigorous physical activity for at least 50% of the class time (Baghurs t et al., 2015). Recess is an important space where students can practice physical activity, and it has been shown to contribute to the recommendations for daily physical activity established by the WHO (Ridgers et al., 2011).
To teach schoolchildren with disabilities, Physical Education teachers require adequate training (González & Macías, 2018; Rubinstein & Franco, 2020). In the case of teaching Physical Education to deaf and hearing-impaired students, specifi c methods have been recommended, adapting communication through sign language and strategies that promote motor skill development (Andrade & Freitas, 2016; Barboza et al., 2019; Fiorini & Manzini, 2018). However, when analyzing the results, knowing the multiple benefits of physical activity in terms of quality of life for deaf and hearing-impaired schoolchildren (Kitterick et al., 2015), constructively, strategies are required so that teachers increase the time of moderate to vigorous physical activity during Physical Education class, focusing on tasks that promote coordination (Dantas & Manoel, 2009), that in the case of people with hearing impairment, would favor the motor skill learning difficulties associated to rhythm, synchronization, adaptation, location in space-time, laterality, orientation and reaction speed (Jafarnezhadgero et al., 2017; Rajendran & Roy, 2011; Walicka-Cupryś et al., 2014).
4 CONCLUSIONS
The state of the question, identifies few studies that evaluate physical activity during Physical Education classes and recess in students with hearing impairment, assessed with SOFIT instrument, the study found statistically significant differences, with greater physical activity performed during recess than in Physical Education class, this same pattern can be found in studies performed in educational contexts with students without disability. Based on the results in Physical Education, it is recommended for teachers, aim content towards the development of skills, emphasizing participation in physical coordination capacities where moderate to vigorous physical activity is increased with higher values, than those presented during recess. In the future, it would be important to perform a greater number of studies evaluating variables that favor participation in physical activity in this population, to provide more information about the teaching-learning process provided by Physical Education professionals who work around students with hearing impairment.
