Learning of Basic Life Support through the Flipped Classroom in Secondary Schoolchildren: A Quasi-Experimental Study with 12-Month Follow-Up.

Background and Objectives: International institutions together with the World Health Organisation recommend the teaching of BLS in schools. Therefore, the objective of this research was to study the feasibility of teaching CPR and AED through the flipped classroom, exploring the medium- and long-term retention of knowledge and practical skills among high school students. Materials and Methods: The sample consisted of 260 secondary schoolchildren (137 in the experimental group (EG) and 123 in the control group (CG)) between 12 and 14 years old (M = 12.75 ± 1.02). Results: The data revealed that the EG obtained better post-course results in the correct position of the hands (p = 0.011), the depth of external cardiac compression (p > 0.001), and the mean time to apply an effective shock with the AED (p = 0.013). The CG obtained better results in compressions with complete chest re-expansion (p = 0.025). These differences disappeared at 6 months (p > 0.05) and 12 months (p > 0.05). Conclusions: A training program based on the flipped classroom is as effective and viable as traditional training, although more efficient since it is applied in less time, in the sequence of action in BLS, CPR skills, and the application of an effective shock with an AED.

Do Gender and BMI Affect the Motor Skills of Five-Year-Old Preschoolers Differently?

BACKGROUND/OBJECTIVE: Weight gain is associated with numerous health complications and constitutes a serious public health problem. Motor competence (MC) can be a protective factor since children's participation and practice in physical activities can improve their health. The objective of this study was to investigate the impact of gender and BMI on MC [i.e., manual dexterity (MD), aiming and catching (A&C), balance (Bal), and total MC percentile (TP)] depending on gender (boy/girl) and BMI (normal weight, overweight or obesity). METHODS: The MABC-2 battery was applied in a sample of 368 preschool children (5.69 ± 0.28 years of age; 54.9% girls). RESULTS: Boys and girls showed statistically significant differences in MC components: boys had higher scores in A&C (p = 0.002), while girls excelled in MD (p < 0.001), Bal (p = 0.035); TP (p < 0.001), and BMI [Bal (p = 0.009); TP (p = 0.050)], with a higher percentile in those children with overweight in both cases. Statistically significant differences were also found in the interactions between gender*BMI [MD (p < 0.001) and TP (p < 0.001)]. CONCLUSIONS: The findings showed that there were notable variations in total percentile, balance, and manual dexterity between boys and girls. In addition, girls outperformed boys in all categories save aiming and catching. However, males who were overweight or obese earned greater percentiles in both balance and the MABC-2 battery's total percentile.

Is It Possible to Improve Motor Competence through a Structured Balance Bike Program in Preschool Children Aged 3 to 6 Years?

This study aimed (1) to investigate the effect of a brief 9-week bike program on preschool motor competence levels and (2) to know the effects of the intervention program on gender. A total of 98 schoolchildren (3.86 ± 0.91 years) from La Coruña (Spain) participated. A pre-post-test quasi-experimental design was used with a control group (CG) made up of 39 students (18 boys) and an experimental group (EG) made up of 59 students (29 boys). Data were gathered using the Movement Assessment Battery for Children-2 (MABC-2). The data demonstrate that the CG and the EG differ significantly from one another before the intervention program in favour of CG in manual dexterity (MD; p < 0.001), balance (Bal; p = 0.003), total test score (TTS; p = 0.001), and total percentile score (TPS; p < 0.001), except in aiming and catching (A&C, p = 0.588). After the application of the 9-week intervention program based on the balance bike, these differences disappear (i.e., MD (p = 0.166), A&C (p = 0.372), Bal (p = 0.219), TTS (p = 0.306), and in TPS (p = 0.259)). The information gathered indicates that implementing intervention programs such as the one applied in this study could have a positive impact on improving motor competence in preschool-aged boys and girls, increasing its level.

Incidence of a Multicomponent Physical Exercise Program on Body Composition in Overweight or Obese People Aged 60 Years or Older from Chile.

This research aimed to explore the changes produced in body mass index (BMI), fat mass percentage (FMP), muscle mass percentage (MMP), and visceral fat percentage (VFP) in 60-year-old or over overweight or obese people after a multicomponent exercise program. This quasi-experimental study involved 70 overweight or obese older people between 60 and 86 years old (M = 73.15; SD = 5.94) who were randomly assigned to a control group (CG, n = 35) and an experimental group (EG, n = 35). At the beginning and at the end of the intervention program, anthropometric and body composition data were collected. The results showed an increase in BMI after the intervention in the CG (p = 0.010) and a decrease in the EG (p < 0.001). The results regarding the FMP indicate a significant decrease in the EG (p < 0.001) after the intervention, as occurs with the VFP (p = 0.003). The MMP increased in the EG (p < 0.001) after the intervention program. Regarding gender, statistically significant differences were found in the MMP after the intervention (p = 0.025), with higher percentages in men in the EG. VFP decreased in both men (p = 0.005) and women (p = 0.019) in the EG. From the results obtained, we can say that a 6-month multicomponent program produces a decrease in BMI, FMP, and VFP and an increase in MMP in its participants. This type of intervention seems to produce a greater increase in muscle mass in men than in women and a decrease in VFP in both genders.

Is It Possible to Improve the Perceived Quality of Life of Overweight or Obese Older People through a Multicomponent Physical Exercise Program?

Multicomponent exercise is a physical exercise modality in which various physical qualities (strength, cardiorespiratory endurance, flexibility, and balance) are developed with an equal distribution of volume in the same session (approximately 60 min) and that has been little explored in improving the quality of life of older adults. The aim of this study was to verify the effect of multicomponent training on self-perceived quality of life in Chilean overweight or obese older people. To this end, a quasi-experimental study with a control group was designed to evaluate self-perceived Quality of Life using the World Health Organization Quality of Life, brief version [Overall Quality of Life (OQOL); Overall Health (OH); Physical Health (PH); Psychological Health (PsH); Social Relations (SR); Environment (E)]. Seventy overweight or obese people aged between 60 and 86 years participated (M = 73.15; SD = 5.94) and were randomized into a control group (CG, n = 35) and an experimental group (EG, n = 35). The results in the EG (pre vs. post-intervention) indicated that there were statistically significant differences in OQOL (p = 0.005), OH (p = 0.014), PH (p < 0.001), PsH (p < 0.001), E (p = 0.015), and SR (p < 0.001) which were not found in the CG in any of the variables (p > 0.050) except in SR (p < 0.001). Regarding sex, post-intervention differences were only found between CG and EG in women in OQOL (p = 0.002), PH (p < 0.001), PsH (p = 0.003), and SR (p < 0.001), but not in OH or E (p > 0.050). These differences were not found among men in any of the variables (p > 0.050). As a conclusion, we can say that a multicomponent physical exercise program applied for 6 months significantly improves the perception of OQOL, OH, PH, PsH, SR, and E in overweight or obese older people. This perception is greater in men than in women.

Is the Over-the-Head Technique an Alternative for Infant CPR Performed by a Single Rescuer? A Randomized Simulation Study with Lifeguards.

(1) Objective: The objective was to evaluate the quality of cardiopulmonary resuscitation (CPR, chest compressions and ventilations) when performed by a lone first responder on an infant victim via the over-the-head technique (OTH) with bag-mask ventilation in comparison with the standard lateral technique (LAT) position. (2) Methods: A randomized simulation crossover study in a baby manikin was conducted. A total of 28 first responders performed each of the techniques in two separate CPR tests (15:2 chest compressions:ventilations ratio), each lasting 5 min with a 15 min resting period. Quality CPR parameters were assessed using an app connected to the manikin. Those variables were related to chest compressions (CC: depth, rate, and correct CC point) and ventilation (number of effective ventilations). Additional variables included perceptions of the ease of execution of CPR. (3) Results: The median global CPR quality (integrated CC + V) was 82% with OTH and 79% with LAT (p = 0.94), whilst the CC quality was 88% with OTH and 80% with LAT (p = 0.67), and ventilation quality was 85% with OTH and 85% with LAT (p = 0.98). Correct chest release was significantly better with OTH (OTH: 92% vs. LAT: 62%, p < 0.001). There were no statistically significant differences in the remaining variables. Ease of execution perceptions favored the use of LAT over OTH. (4) Conclusions: Chest compressions and ventilations can be performed with similar quality in an infant manikin by lifeguards both with the standard recommended position (LAT) and the alternative OTH. This option could give some advantages in terms of optimal chest release between compressions. Our results should encourage the assessment of OTH in some selected cases and situations as when a lone rescuer is present and/or there are physical conditions that could impede the lateral rescue position.

News of the Pedagogical Models in Physical Education-A Quick Review.

In the last two decades, research has proliferated in the field of pedagogical models used in school Physical Education. The growth is so high that it is necessary to do a quick review to know which models currently exist and which are emerging. The objective of this work is to collect all the models or pedagogical approaches present in the scientific literature related to school Physical Education and to make known, to the scientific and academic community, its main purposes and characteristics. A quick review of the literature found in the Web of Science and Scopus databases has been carried out using "pedagogical model" and "Physical Education" as descriptors. The results revealed a total of 19 pedagogical approaches that record scientific evidence linked to their application in the classroom. It was detected that some models or approaches were more scientifically supported than others, as is the case for Cooperative Learning, Sports Education, or Teaching Games for Understanding, while others barely registered in international scientific literature. It was concluded that researchers need to work together with Physical Education teachers to analyze the effectiveness of all these approaches. School teachers are also encouraged to vary their pedagogical approach depending on the content they are working on and the positive effects they are looking for in the psychic, motor, affective-emotional, and social domains of the students. Finally, it is proposed to researchers who promote new models or approaches a greater clarity of these to facilitate their application in the field of school Physical Education, since some difficulty has been detected in the practical application of some approaches.

Variations in Manual Dexterity in 11- and 12-Year-Old Children in the North of Spain in the SARS-CoV-2 Lockdown.

Between March and June 2019, the SARS-CoV-2 virus broke out in Spain. The lockdown in response entailed the modification of certain habits in the infant−juvenile population, such as those related to the practice of physical activity and the implications derived from it. The aim of this study was to learn the impacts that lockdown had on manual dexterity in children aged 11−12 years. Methods: A total of 50 Spanish children aged 11−12 years (M = 11.40; SD = 0.50) participated, 33 (66%) boys and 17 (34%) girls. The Movement Assessment Battery for Children 2 (Movement ABC-2) and an ad hoc questionnaire for socio-demographic data and other relevant information were administered for the data collection. Results: There are significant differences (p < 0.05) in the results for the manual dexterity variables measured by the peg turning and line drawing tests as well as by the measured, scalar and percentile dimension scores for manual dexterity between before and after the lockdown in both boys and girls. No significant differences were found in measurements related to the triangle assembly variable (p = 0.125). Conclusions: A significant negative impact of SARS-CoV-2 lockdown on manual dexterity values was evident in boys and girls aged 11−12 years.

Textbooks and Learning Materials in Physical Education in the International Context: Literature Review.

This paper presents a review of the research carried out internationally in recent years regarding textbooks, teaching materials, and the field of physical education. The objectives to which this article aims are as follows: To offer a compilation of current research papers published in the Scopus, Web of Science, and Dialnet databases and to provide a classification of the research lines undertaken on the subject. The information used is based on a review of studies listed in Scopus, Web of Science, and Dialnet. For this, a systematic review was carried out with the terms: "curricular resources", "didactic materials", "digital resources", "educational resource", "physical education", and "textbooks", allowing the selection of original articles, which included information on this line of research. For the literature review, only articles that presented scientific evidence were used, discarding merely descriptive articles or didactic experiences that were not investigated with the scientific protocol. A total of 589 articles were found, although after applying the review's inclusion criteria, they were reduced to 54 articles. The investigations do not follow a common protocol and the researchers address multiple objectives in them, highlighting the studies on the implicit ideological discourse in the images of physical education textbooks. The results reveal a diversity of research, in particular, studies involving ideological discourse. Insofar as methodology, content analysis of textbooks and materials was the most common approach.

Implications for balance in 11- and 12-year-old children in northern Spain during SARS-CoV-2 lockdown.

Introduction: The home lockdown due to the appearance of SARS-CoV-2 in Spanish society led to changes in certain habits in children and adolescents. These habits were related to the practice of physical activity and the implications of higher rates of sedentary activities. This lockdown lasted from March to June 2020. The aim of this study was to determine the implication that lockdown in Spain due to the SARS-CoV-2 virus outbreak had on balance in 11-12 year-old schoolchildren. Materials and methods: In total, 50 Spanish children aged 11-12 years (M = 11.40, SD = 0.50) participated, 33 (66%) boys and 17 (34%) girls. The Movement Assessment Battery for Children 2 (Movement ABC-2) and an ad hoc questionnaire for sociodemographic data and other relevant information were used for the three data collections. Results: There are significant differences (p < 0.05) in the results for balance variables measured by static balance tests on supports in the total sample, in boys and girls. There are also significant differences in the total sample as well as in the boys in the heel-toe backward walking test. In addition, there are significant differences in mean, scalar and percentile dimension scores for balance between before and after lockdown in both boys and girls. No significant differences were found in the total sample or by gender in measurements related to the zigzag jumping test with dominant as well as non-dominant leg in girls (p = 0.317). Conclusion: As a consequence of SARS-CoV-2 confinement, there was a worsening of balance values in children aged 11-12 years.

Disruptive Behaviors in Physical Education: A Matched Study of Social Skills and Sport Practice in a Region of Spain.

Disruptive behaviors in physical education cause conflicts among students and, consequently, an abnormal development of classes. Therefore, finding the variables that can solve them is an urgent aspect to achieve an adequate learning environment in the 21st century school. The aim of this study was to analyze what happens to disruptive behaviors in relation to systematic and regulated sports and social practice in a sample of Spanish primary school students. Five hundred and forty-eight schoolchildren (276 were girls (50.4%)) participated with a mean age of 10.98 (SD = 0.71). The results show a significant main effect in terms of social skills in relatedness (p < 0.001), irresponsibility (p < 0.001), failure to follow directions (p < 0.001), distracting or disturbing others (p < 0.001), and in poor self-management (p < 0.001) with higher scores in disruptive behaviors in students with lower social skills. Regarding sports practice, only a significant main effect was found in relatedness (p < 0.001) and in poor self-management (p < 0.001), with the highest scores the schoolchildren who do not practice sports. Schoolchildren with high social skills obtain lower scores in disruptive behaviors. Likewise, schoolchildren who play sports have lower scores in relatedness and poor self-management.

Central and Peripheral Fatigue in Recreational Trail Runners: A Pilot Study.

BACKGROUND: Understanding fatigue mechanisms is crucial for exercise performance. However, scientific evidence on non-invasive methods for assessing fatigue in trail running competitions is scarce, especially when vertical kilometer trail running races (VK) are considered. The main purpose of this study was to assess the autonomic nervous system (ANS) activity (i.e., central fatigue) and the state of muscle activation (i.e., peripheral fatigue) before and after a VK competition. METHODS: A cross-sectional pilot study was performed. After applying inclusion/exclusion criteria, 8 recreational male trail runners (31.63 ± 7.21 yrs, 1.75 m ± 0.05 m, 70.38 ± 5.41 kg, BMI: 22.88 ± 0.48, running experience: 8.0 ± 3.63 yrs, weekly training volume: 58.75 ± 10.35 km) volunteered to participate and were assessed for both central (i.e., via heart rate variability, HRV) and peripheral (via tensiomyography, TMG) fatigue before and after a VK race. RESULTS: After the VK, resting heart rate, RMSSD (p = 0.01 for both) and SDNN significantly decreased (p = 0.02), while the stress score and the sympathetic-parasympathetic ratio increased (p = 0.01 and p = 0.02, respectively). The TMG analyses suggest that runners already suffered peripheral fatigue before the VK and that 20-30 min are enough for muscular recovery after the race. In summary, our data suggest that participants experienced a pre-competition fatigue status. Further longitudinal studies are necessary to investigate the mechanisms underlying fatigue during trail running races, while training periodization and tapering strategies could play a key role for minimizing pre-competition fatigue status.

The Effects of an Intervention Based on the Flipped Classroom on the Learning of Basic Life Support in Schoolchildren Aged 10-13 Years: A Quasi-Experimental Study.

Most out-of-hospital cardiac arrests are attended first by bystanders who are usually friends and/or relatives of the victim. Therefore, the objective of this research was to analyse the impact of a training process based on the flipped classroom on basic life support skills in primary education students. The sample consisted of 308 children (148 experimental group (EG) and 160 control group (CG)) between 10 and 13 years old (M = 10.68 ± 0.64) from 2 schools in Galicia, Spain. The data reveal that the quality parameters are obtained in the number of total compressions in 2 min (CG = 213 and EG = 217; p = 0.024) and in the percentage of correct compressions (CG = 87.23% and EG = 91.6%; p = 0.013) except for the mean depth and the percentage of correct compressions, which were not reached in any case. Regarding the application of an effective discharge with the Automated external defibrillator (AED), there were no significant differences in the time used by schoolchildren between both methods (p = 0.795), but 97.5% (n = 156) of the CG and 100% (n = 148) of the EG are able to do it in just over 1 min. Based on the results obtained, we can conclude that a training program based on the flipped classroom is as effective and viable as traditional training in psychomotricity on CPR techniques and the application of an effective discharge using an AED.

Influence of the Type of Physician on Survival from Emergency-Medical-Service-Witnessed Cardiac Arrest: An Observational Study.

Out-of-hospital cardiac arrest resuscitation by non-emergency dedicated physicians may not be positively associated with survival, as these physicians have less experience and exposure than specialised dedicated personnel. The aim of this study was to compare the survival results of the teams led by emergency dedicated physicians (EDPhy) with those of the teams led by non-emergency dedicated physicians (N-EDPhy) and with a team of basic life support (BLS) emergency technicians (EMTs) used as the control group. A retrospective, multicentre study of emergency-medical-service-witnessed cardiac arrest from medical causes in adults was performed. The records from 2006 to 2016 in a database of a regional emergency system were analysed and updated up to 31 December 2021. Two groups were studied: initial shockable and non-shockable rhythms. In total, 1359 resuscitation attempts were analysed, 281 of which belonged to the shockable group, and 1077 belonged to the non-shockable rhythm group. Any onsite return of spontaneous circulation, patients admitted to the hospital alive, global survival, and survival with a cerebral performance category (CPC) of 1-2 (good and moderate cerebral performance) were studied, with both of the latter categories considered at 30 days, 1 year (primary outcome), and 5 years. The shockable and non-shockable rhythm group (and CPC 1-2) survivals at 1 year were, respectively, as follows: EDPhy, 66.7 % (63.4%) and 14.0% (12.3%); N-EDPhy, 16.0% (16.0%) and 1.96 % (1.47%); and EMTs 32.0% (29.7%) and 1.3% (0.84%). The crude ORs were EDPhy vs. N-EDPhy, 10.50 (5.67) and 8.16 (4.63) (all p < 0.05); EDPhy vs. EMTs, 4.25 (2.65) and 12.86 (7.80) (p < 0.05); and N-EDPhy vs. EMTs, 0.50 (0.76) (p < 0.05) and 1.56 (1.32) (p > 0.05). The presence of an EDPhy was positively related to all the survival and CPC rates.

Music Therapy and Parkinson's Disease: A Systematic Review from 2015-2020.

Parkinson's disease can be approached from various points of view, one of which is music therapy-a complementary therapy to a pharmacological one. This work aims to compile the scientific evidence published in the last five years (2015-2020) on the effects of music therapy in patients with Parkinson's disease. A systematic review has been performed using the Web of Science and Scopus databases with the descriptors "music therapy" and "Parkinson's disease". A total of 281 eligible articles were identified, which, after applying the inclusion and exclusion criteria, were reduced to 58 papers. The results display a great diversity of evidence, confirming positive effects on various spheres. All mentioned patients with Parkinson's disease had experienced different music therapy programs. Some studies focused on the motor component, which can be addressed through listening, body rhythm, and rhythmic auditory stimulation. Other studies confirm effects on communication, swallowing, breathing, and the emotional aspect through programs that focus on singing, either individually or in groups, in order to improve the quality of life of people with PD. It was concluded that music therapy programs can achieve improvements in various areas of patients with Parkinson's.

Impact of a Series of Educational Talks Taught by Health Professionals to Promote Healthy Snack Choices among Children.

BACKGROUND: One of the great challenges facing today's society is the need to combat overweight and obesity in schoolchildren. This study aimed to analyze the impact of a cycle of didactic talks-given to families by a specialist in pediatrics, a specialist in nutrition and dietetics and a specialist in physical exercise-on childrens' snack choices and nutrition quality. METHODS: A longitudinal, quasi-experimental and quantitative investigation was designed, working with a total sample of 50 students divided into control and experimental groups. The nutritional quality of daily snacks was recorded during the month before and the month after the cycle of talks given by health experts. RESULTS: An increase in the nutritional quality of the snacks was observed in the days after the talk-but, after a week, values returned to normal. CONCLUSIONS: The giving of educational talks to promote healthy habits may have a positive impact on the nutritional quality of school snacks in the days immediately following the talks. However, some forgetfulness was detected over time, which reduced the nutritional quality of the snacks once more. For future work, it is recommended that researchers measure the impact produced by giving regular talks.
