The response of the body to vigorous physical activity is a multiorgan system phenomenon. As a result, the body undergoes profound morphologic and functional alterations, but as there are different kinds of physical activities, the degree of these changes is highly variable as well. Considering many sudden cardiac deaths in sport, it is needless to say how important it is to know where the border of normal changes of the body due to physical activity is and when these changes become unhealthy. Also it is very important to distinguish physiological changes of the body due to physical activity and pathological changes due to some cardiac diseases. In order to prevent sudden cardiac deaths in sport, it is very important to distinguish athletes heart syndrome and hypertrophic cardiomiopathy, dilatative cardiomiopathy, aritmogenic cardiomiopathy of the right ventricle and myocarditis. More frequent physical examinations of athletes are recommended.

Introduction Sudden cardiac death in athletes is a growing problem, despite the huge existing knowledge in medicine and sports. Effects of vigorous physical activity In response to vigorous physical activity, the body undergoes profound morphologic and functional changes. These changes are usually healthy, but sometimes may gravitate to some cardiac diseases. But still, most sudden cardiac deaths are due to previous unknown diseases. Causes of sudden cardiac death The most common cause of sudden cardiac death in athletes is hypertrophic cardiomyopathy. Other reasons are congenital coronary artery anomalies, myocarditis, dilatative cardiomyopathy, arrhythmogenic cardiomyopathy of the right ventricle, sarcoidosis, mitral valve prolapse, aortic valve stenosis, atherosclerosis, long QT syndrome, and blunt impact to the chest. Conclusion Bearing in mind the above mentioned, more frequent physical examinations of athletes are recommended.

Prepubertal Girls

The purpose of this study was to examine the relationships between physical activity and physical fitness and adiposity in a sample of 77 girls, aged 10–11 years. Physical activity was assessed by 7-day physical activity recall by which children reported how much time they spent on low and moderate-to-vigorous physical activities. Physical fitness was measured by EUROFIT test battery. Adiposity was estimated by sum of five skinfolds. The main finding of the study was that moderate-to-vigorous physical activity and adiposity were significant predictors (with 16–34% accounted variance) of physical fitness tests where the body mass affects performance. Indicators of physical activity and adiposity were not significantly related with fitness items requiring muscular strength, balance, flexibility, and speed of limb movement. Furthermore, moderate-to-vigorous physical activity and aerobic fitness predicted 22% of variance in adiposity in girls.

Physical activity participation is a non-pharmaceutical intervention that can be utilized to maintain and improve cognitive function in aging adults. Although simple physical activities yield positive results in regards to cognitive function, cognitively and motorically complex physical activities may have an even greater benefit on neuroplasticity for older adults. Commercially available products such as physical activity apps or exergames offer this population a means to engage in regular physical activity on their own. However, a taxonomy is necessary to help distinguish simpler physical activities from more complex physical activities. The taxonomy proposed in this paper carefully considers the following characteristics: the stability or transport of the body, object manipulation, intertrial variability, the environmental context and the reaction or to others. The dimensions of the taxonomy are operationally defined and practical applications are provided.

Objective: The objective of this study was twofold. First, analyze physical activity (PA) levels during physical education (PE) with different durations (45 and 90 minutes) according to student’s obesity status. Secondly, we examine the relative contribution of 45 and 90 minutes PE (45PE and 90PE) for the compliance of the daily PA recommendations according to the body mass index (BMI). Methods: Four public schools were analyzed. The sample comprised 472 youngsters (266 girls) aged between 10 and 18 years old. PA was assessed using an Actigraph accelerometer. The participants were categorized as non-overweight (NOW) and overweight/obese (OW) according to the sex-adjusted BMI. Results: The proportion of Moderate and Vigorous Physical Activity (MVPA) was lower than the 50% recommended by guidelines regardless the PE duration. Our data showed that only 26% of NOW and 13% of OW in the 45PE achieved the recommended levels while 17% of NOW and 11% of OW achieved the recommendation in 90PE. Overall, the 90PE had a higher absolute contribution for daily MVPA recommendations compliance than 45PE. Conclusion: During PE classes youngsters spent a reduced amount of time in MVPA, independently of their weight status.Resumen. Objetivo: Este estudio tiene un doble objetivo.

The overall orientation of the research problem is focused on the physical activity level of the participants from the aspect of different intensities of motor engagement and their impact on morphological characteristics and motor skills with an intention of determining whether there are statistically significant differences between groups. In a sample of 103 students, aged between 18 and 20 years (18.9 ± 0.4), the female students were divided into three subsamples according to the level of physical activity: highly active, active and inactive. The study which was conducted had a transversal character. The data obtained in the survey were analysed using the univariate (ANOVA) and multivariate (MANOVA) statistical methods. The motor skills mere monitored by the use of the Eurofit Test Battery (wide-angle seated forward bend, standing long jump, pull-up endurance, 10 x 5m shuttle run and endurance shuttle run- beep test). The following morphological characteristics were considered: height, weight, body mass index, percentage of muscular mass and fat mass, as well as waist circumference. The obtained results indicate the existence of statistically significant differences between the % body muscle mass´ groups (p < 0.05) and motor skills parameters (sit and reach, p<0.01; standing broad jump, bent arm hang, 10x5m shuttlerun, beep test, p<0.001) of participants according to physical activity level. In conclusion, participants with a high level of physical activities have higher average values than the participants with light level of physical activities when considering the variables for assessing pliability, strength and agility.Resumen. La orientación general del problema de investigación se centra en el nivel de actividad física de las participantes desde el aspecto de diferentes intensidades de compromiso motor y su impacto en las características morfológicas y habilidades motrices con la intención de determinar si existen diferencias estadísticamente significativas entre los grupos. En una muestra de 103 alumnas, con edades comprendidas entre los 18 y 20 años (18,9 ± 0,4), las estudiantes fueron divididas en tres grupos de acuerdo con el nivel de actividad física de cada uno: muy activas, activas e inactivas. El estudio llevado a cabo tuvo un carácter transversal. Los datos obtenidos mediante cuestionarios fueron analizados utilizando un análisis de la varianza (ANOVA) y un análisis multivariante de la varianza (MANOVA). Las habilidades fueron controladas mediante la batería Eurofit y para las características morfológicas, se midió la altura, peso, índice de masa corporal, porcentaje de masa muscular, masa grasa y la circunferencia de la cintura. Los resultados obtenidos indican la existencia de diferencias entre los grupos estudiados respecto al % de masa muscular (p <0.05) y las habilidades motrices (flexibilidad-inclinación hacia adelante, p<0.01; salto de longitud a pie, fuerza resistencia mediante flexión de brazos, 10 x 5 m carrera de ida y vuelta y Beep Test, p<0.001) de los participantes según el nivel de actividad física. En conclusión, las participantes con alto nivel de actividad física tienen mayores valores de habilidad motriz que las participantes que el resto en función de las variables flexibilidad, capacidad aeróbica, fuerza y agilidad.

Activity Enjoyment

Physical activity declines from childhood to adolescence. Affective factors may partially account for this decline. The present study investigated whether within-person changes in children’s enjoyment of physical activity are associated with the age-related decline in physical activity. Children (N = 169, 54% female, 56% Hispanic; 8–12 years old at enrollment) took part in a longitudinal study with six assessment waves across 3 years. At each wave, enjoyment of physical activity was reported, and moderate to vigorous physical activity (MVPA) was measured with an accelerometer across seven consecutive days. MVPA and enjoyment of physical activity both declined across waves. Multilevel analyses revealed that within-person changes in enjoyment moderated the effects of age on within-person changes in MVPA. Enjoyment appeared to be a dynamic factor that buffered against the age-related decline in physical activity in youth. These findings call for health promotion interventions that encourage enjoyable physical activities.

Crucial Part

Cystic Fibrosis (CF) is a multisystemic condition that affects almost every organ in the body, but especially the lungs. Regular physical activity (PA) can significantly slow disease progression and has become a crucial part of CF care. Previous research evaluating PA in CF has been hindered by the use of cut-points developed for healthy populations and the investigation of collinear movement behaviours as independent entities, both of which are likely to have confounded their findings and any subsequent inferences regarding associated health outcomes. Therefore, the overall aim of this thesis was to investigate the measurement and analysis of PA in those with CF. An initial systematic review provided recommendations for research calibrating accelerometry in paediatric clinical populations, highlighting that the pathophysiology of the condition must be accounted for and that the protocol should include a broad range of activities varying in intensity (Chapter 4). Subsequently, Chapter 5 developed and cross-validated raw acceleration CF-specific cut-points in youth which were then further assessed in Chapter 6, demonstrating that the CF-specific thresholds were associated with higher levels of moderate-to-vigorous physical activity (MVPA) and sedentary time (SED) and lower levels of light PA compared to generic cut-points. Furthermore, lung function was associated with light PA when using condition-specific thresholds. Further investigation of the relationship between PA and health in Chapter 7 found that reallocating time from sedentary to any other behaviour was beneficial for lung function, with the greatest improvements observed when SED was reallocated to sleep or MVPA. Finally, Chapter 8 developed and validated machine learning algorithms that achieved excellent accuracy to classify PA types and intensities in youth with CF. In conclusion, these findings significantly advance the assessment of PA, enhancing our understanding of the relationship between PA and health in CF and informing future condition-specific PA guidelines, care strategies and interventions.

• Background Myoelectric noise and baseline wander, artifacts that appear when patients move during electrocardiographic monitoring, can cause false alarms. This problem can be addressed by using a reduced lead set and placing electrodes on the anterior part of the torso only. The Mason-Likar modification of the standard 12-lead electrocardiogram and the EASI lead system are 2 alternative systems for lead placement. • Objectives To test the hypothesis that the EASI lead system is less susceptible to artifacts than is the Mason-Likar modification of the standard 12-lead electrocardiogram. • Methods Baseline wander and myoelectric noise amplitudes of EASI and Mason-Likar 12-lead electrocardiograms were compared. Twenty healthy volunteers participated. Both lead systems were recorded simultaneously for different types of physical activities. For each lead in each subject, baseline wander and myoelectric noise were measured for both systems, at rest and during each physical activity. • Results The outcome for baseline wander was mixed. For myoelectric noise content, the EASI system performed better for the limb leads in the different physical activities. In the precordial leads, the differences were minimal or mixed. However, for supine-to-right turning, EASI performed worse than the Mason-Likar system. • Conclusions The 2 systems have similar susceptibilities to baseline wander. The EASI system is, however, less susceptible to myoelectric noise than is the Mason-Likar system. EASI performed worse than Mason-Likar for turning supine to right, because only the EASI system uses an electrode in the right-midaxillary line.

Objectives. This study investigated the effectiveness of Teaching Games for Understanding (TGfU) intervention on the moderate-to-vigorous physical activity (MVPA) levels of students from Grades 9 and 10. Methods. A total of 118 students from four classes (two TGfU groups and two technique groups) participated in this study. Accelerometers were used to measure the MVPA time of students, and formal interviews were conducted to identify the factors that contributed to the MVPA level of students in TGfU classes. Results. The results reveal that the TGfU [t (1, 57) = - 11.622, p <.001, and d =.841] and technical [t (1, 61) = -4.232, p <.001, and d =.236] group exhibited significantly improved MVPA levels in intervention phase. During the intervention period, the MVPA time of the TGfU group (M = 20.26, SD = 3.74) was significantly longer than that of the technique group [M = 17.62, SD = 3.37, t (1, 118) = 4.023, p < .001, and d = .35]. Moreover, in the TGfU classes, boys (M=21.476, SD =.719) spent significantly more time engaging in MVPA than girls (M = 19.135, SD = .645) [F (1, 57) = 5.807, p = .019, and η2= .09]. However, no significant differences were determined between the MVPA levels of high- and low-skilled students. Data gathered through interviews suggested that the nature of the games, the small-sided team, and the freedom and enjoyment experienced by the students through games may explain the high MVPA levels observed in the TGfU classes. Conclusion. TGfU intervention can potentially be used to promote physical activities and attain the recommended MVPA time in PE classes (50% class time).

There is a concern to use masks during physical activities when exercising and working. Wearing masks during physical activity will pose a risk to physiological changes in the body and human heat strain by the principle of a mask can block the respiratory tract. This study aims to determine how much the human physiological changes quantitatively and qualitatively when using different types of medical masks, cloths and N95. There were 10 respondents as a sample of this study. The results obtained show that the different types of masks to the physiological response of the human body, cloth masks can affect the physiological changes the highest compared to medical masks and N95. The subjective response in the form of thermal comfort, mask sensation, and thermal sensation shows that of the 3 types of masks, the N95 mask is the mask that is the most uncomfortable when worn. The recommendations of the 3 types of masks are medical masks because they affect the slightest increase in the risk of heat stress while the cloth masks have the highest increase in tympanic temperature and Physiological Strain Index.
