    This study examined the effectiveness of Problem-based Learning (PBL) approach on enhancing graduate in-service physical education teachers' academic self-confidence, leadership and initiation. academic affect, and information processmg competence. A pre-test/post-test with quasi-experimental design was used. 27 graduate in-service physical education teachers from the National Institute of Education, Nanyang Technological University, Singapore, in a health-related and wellness module participated in this study. The intervention comprised teaching participants using a PBL approach for 12 teaching weeks. Measuring scales of high validity and reliability were developed for this study to measure participants' self-concept, leadership, academic affect and their information processing competence. Averaged post-test scores in most of generic skill aspects ( 8 out of II) were significantly higher than pre-test scores. Students had in general more positive attitudes toward the module and themselves at post- test than they had at pre-test. The results strongly support that teaching using a PBL approach is beneficial to both students' generic skill development and academic affect to teaching and learning.

    The study examined the motion sensor outputs of Singaporean children and adolescents of both sexes to walking and running on a motorized treadmill (Quinton Series 90) under controlled laboratory conditions. 58 youths of normal body mass (N=58, age: 13.2±3.0 y; height: 1.53±0.02 m; body mass: 45.5±14.2 kg; BMI: 18.8± 3.0 kg/m2; Tanner rating: 2.5±1.3) were recruited for the study. Accelerometer (ActiGraph GT 1 M) activity (ActiCounts in counts/min) and step rate (ActiSteps in steps/min) and pedometer (Omron HJ 005-E) step rate (PedoSteps in steps/min), oxygen uptake (in ml/kg/min) and heart rate (in bpm) were obtained from 5-minutes stages of 0 % gradient of treadmill walking at 4 km/hr and running at 6 km/hr and 8 km/hr. Walking at 4 km/hr was estimated at 4.0-6.0 METs, whilst running at 6 km/hr and 8 km/hr was estimated at 6.3-8.6 and 10.0-11.4 METs, respectively. Motion sensor outputs increased significantly with treadmill speeds (76-101 % for ActiCounts; 22-24 % for ActiSteps and18-25 % for PedoSteps, all p<0.01) as did oxygen uptake (48-55 %) and heart rate (27-28 %) but there was no sex difference in activity or step rate or physiological responses (p>0.01). No meaningful relationships were obtained between accelerometer activity rate and oxygen uptake or heart rate. There was acceptable agreement between accelerometer and pedometer step rate for the walking and running on the treadmill but the difference between accelerometer and pedometer step rate was smallest at a treadmill running speed of 6 km/hr. These results show that accelerometer and pedometer step rates are useful and suitable measurements of physical activity involving walking and running among Singaporean children and adolescents of normal body mass. Further investigations are necessary to fully exploit the use of accelerometer data in physical activity research among young people.

    Classroom-based physical activity (PA) interventions have received considerable attention due to improvements seen in academic achievement, classroom behaviors, and attitude toward PA. The purpose of this study was to evaluate the effectiveness of the Brain Breaks® Physical Activity Solutions in changing children’s attitudes toward PA. Students (N = 3036) aged 8–11 years from schools in Croatia, Lithuania, Macedonia, Poland, Romania, Serbia, South Africa, and Turkey were randomly assigned to either a control or an experimental group. The experimental group received Brain Breaks® videos during classroom sessions throughout the four months of intervention. Student attitudes toward PA were measured using the Attitudes toward Physical Activity Scale (APAS) before and after the intervention. Repeated measures ANOVA indicated a time interaction effect for all APAS variables except fitness. Time-by-group interaction effects with different effect sizes were found for most APAS variables, with the greatest gain effect noted in the experimental group for self-efficacy, followed by learning from the videos concerning PA benefits, exercise importance, and enjoyment from engaging in PA. This study provides evidence supporting Brain Breaks® in terms of learning experience, attitudes towards PA, and personal motivation. Using exercise videos is recommended as an interactive, technology-based PA solution that can be easily integrated into the school setting.

    Obesity has reached global epidemic proportions over the past 10 years. As countries become more affluent, their populations tend to adopt caloric balance problems that have plagued the USA and Western Europe. Obesity is classified as the second most serious reversible health problem, after smoking in the world today. The relationship between obesity and cardiovascular diseases is well documented. The increase in obesity in Asian countries is remarkable. In 2004, the prevalence of obesity in the adult population in Singapore increased upto 16% (high risk category: ≥ 27.5kg/m2) and prompted many forms of government action, encouraging collaboration between businesses, the educational system and non-governmental organizations. This paper reviews the rise of obesity in Singapore and some of the approaches being implemented to address this concern. Singapore, a multiethnic country, with Chinese, Indian and Malay populations, has to address diversity in customs, diet and religions to combat obesity. The collaborative efforts of various organizations such as the Ministry of Health (MOH), Ministry of Education (MOE) and the Health Promotion Board (HPB) have successfully improved the health status of Singaporeans. The fact that the rise in obesity in Singapore is lower than in other neighboring Asian countries attests to the partial success of the collaborative efforts.

    During the novel coronavirus (COVID-19) pandemic, physical activity (PA) behaviors were altered worldwide due to public health measures such as “lockdown.” This study described PA among adults residing in 11 countries during COVID-19 lockdown and examined factors associated with PA engagement. We conducted a cross-sectional anonymous survey among adults (≥18 years old) in 11 countries (Brazil, Bulgaria, China, India, Ireland, Malaysia, North Macedonia, Singapore, Spain, Turkey, United States). Of 11,775 participants, 63.7% were female and 52.8% were 18–34 years old. More than 40% of participants were insufficiently active (43.9%) and reported a decrease in their PA during lockdown (44.8%). Statistically significant differences were observed in (1) proportions of participants being insufficiently active, (2) level of PA, and (3) decrease in PA across the 11 countries. More stringent governmental policy responses were associated with greater likelihood of being insufficiently active during lockdown (adjusted odds ratio = 1.22, 95% confidence interval = 1.03, 1.45). Higher depression or anxiety scores were associated with greater likelihood of decreased level of PA during lockdown.We found substantial reductions in PA levels during COVID-19 lockdown across countries. Country-specific PA promotion interventions are needed during this and similar global emergencies.

    Govindaswamy, V. V.
    In the modern era, health professional including scientists. health workers and researchers from different disciplines are focusing on body composition in the area of assessments. physiology. psychology. nutrition, etc. These valuable information garnered from research. and clinical practices is becoming an important factor in determining obesity such as formulation of an exercise programme and diet regiment. psychological profiles based on body image, nutritional status. functional capacity and risk for chronic diseases. Body composition is necessary for an individual to maintain proper work capacity, muscular strength. and the ability to perform daily tasks such as walking and lifting. Negative changes in body composition can lead to decline in physical performance capabilities of the individual. Currently there are number of indirect ways to assess body composition such as dual energy x-ray absorptiometry ( DEXA), under water weighing. body mass index (BMI), waist hip ratio ( WHR). bioelectric impedance ( BIA). skin fold measurement, circumference and girth measurements. These methods differ in accuracy and precision. Body composition is also affected by factors like hydration. This chapter focuses on the components of body composition and the various body composition techniques. In addition. it discusses the effects of hydration status on body composition.

    Physical education & sports science expert book series
    (Office of Education Research, National Institute of Education, Singapore, 2020)
    To design and write a book on chapters pertaining to a variety of sports for children and adolescents to enjoy the process of being physically active.
    Background The American College of Sports Medicine (ACSM, 2015) states that a sedentary lifestyle is one of the major risk factors for obesity and cardiovascular disease. Therefore, physical activity is essential and it starts from a young age. Children have to be exposed to a variety of sports, games and activities. ACSM recommends 60 minutes daily of physical activity for children and adolescents. If children are unable to accumulate 60 minutes in day, they can begin with a lower duration and subsequently increasing the duration slowly as they progress over the months. The following chapters are written and designed by our experts in their special area of work and sport that will provide a deeper understanding and greater insight to sports and exercise in general, from a recreational perspective to a competitive level. Each chapter will reveal the history, background, basic rules of the sport, and how to implement modified games during PE lessons. The chapters also provide PE educators, coaches and parents with necessary tools to teach the sport.

    The purpose of this study was to investigate the effects of soy protein supplementation to improve performance and recovery during repeated running anaerobic sprint test (RAST). Ten males (age: 23.2 ± 1.23 yrs) performed two RAST with a soy milk intervention (SOY; 500 mL soy milk + 4 g stevia sweetener) and a placebo control (CON; 500 mL water + 4 g stevia sweetener) over 7 days. The RAST consisted of six 35-m sprints with a 10-sec recovery between each sprint. The total effort time (sec) was not significant between SOY (32.77 ± 1.23) and CON (33.28 ± 1.71) (P = 0.179). Fatigue index in SOY (31.64 ± 5.20) was significantly lower than CON (37.30 ± 5.70) (P = 0.023). Mean power (Watts) (Soy: 499.27 ± 62.72, Con: 486.39 ± 86.13) (P = 0.410), relative power (Watts) (Soy: 9.34 ± 1.02, Con: 9.55 ± 1.51) (P = 0.461), peak blood lactate (mmol·L-1) (Soy: 9.75 ± 1.61, Con: 10.24 ± 1.90) (P = 0.488), and peak blood glucose (mmol·L-1) (Soy: 23.94 ± 3.90, Con: 25.09 ± 4.61) (P = 0.497) between trials were not significant. Peak blood lactate (r = -0.654) and glucose (r = -0.662) concentrations were inversely associated with mean power in the SOY trial. The results indicate that the soy milk intervention in RAST significantly lowered the fatigue index and, therefore, may be used to enhance sports performance involving anaerobic activities.
