LANGUAGE NOTE | Document text in Chinese; abstract also in English. The purpose of this study was to investigate the effects of the power fitness yoga course of Community University intervention on basic physiological parameters, anthropometric parameters as well as muscular and cardiopulmonary fitness. Fifteen females were participated this study. Subjects took a 90-minutes power fitness yoga course once a week for 12 weeks. The resting heart rate, blood pressure, body weight, body fat percentage, waist-to-hip ratio, body mass index, back strength, sit-up test as well as 3-minutes step test of subjects were tested before and after the course. Paired t-tests were used to compare the variables. The results showed that after 12 weeks of power fitness yoga course, the resting heart rate, diastolic pressure, body fat percentage and waist-to-hip ratio had significant decreased. The cardiopulmonary index of 3-minutes step test was significantly increased. There were no differences on the other variables (p>.05). The results indicate that 12-week power fitness yoga course in Community University can improve the resting heart rate, diastolic pressure, waist- to-hip ratio and body fat percentage as well as promote cardiovascular fitness. 本研究旨在探討社區大學之強力適能瑜珈課程對基礎生理值、體位值、肌肉及心肺適能等生理值的影響。研究以15名女性學員為對象，進行為期12週的研究，研究期間受試者在老師的指導下每週從事一次90分鐘的強力適能瑜珈運動。在實驗前、後均測量受試者之安靜心跳率、血壓、體重、體脂率、腰臀比、身體質量指數、背肌力、1分鐘屈膝仰臥起坐及體力指數，並以相依樣本t考驗比較前、後測各項數值之差異。結果顯示：經過12週的課程後，受試者之安靜心跳率、舒張壓、體脂率與腰臀比均顯著下降，且體力指數有顯著之提升，其他數值則無差異。本研究結果證實社區大學所開設之強力適能瑜珈課程能有效降低安靜心跳率、舒張壓、腰臀比與體脂率，並提升心肺適能。

Consumption Frequency

Background: Observationally, sugar-sweetened beverage (SSB) consumption is associated with adiposity in Western children but could be confounded. We examined the association of SSB frequency with adiposity in the non-Western setting of Hong Kong. Methods: We examined the associations of SSB consumption frequency at 11 and 13 years assessed by using a food frequency questionnaire with subsequent body mass index (BMI) z-score and overweight/obesity up to 18 years using generalized estimating equations, and with waist circumference, waist-to-hip ratio, and body fat percentage at 16–19 years using linear regression in a population-representative Chinese birth cohort “Children of 1997” (n = 3628). Results: At 11 and 13 years, 6.8% and 8.2% of children respectively consumed SSB daily. Neither SSB frequency at 11 nor at 13 years was associated with subsequent BMI z-score or overweight/obesity up to 18 years, or with waist circumference, waist-to-hip ratio, or body fat percentage at 16–19 years adjusted for age, sex, socioeconomic position, health status, physical activity and other food consumption, although bias to the null from under-reporting cannot be eliminated. Conclusion: Although we cannot definitively exclude a small association of SSB frequency with adiposity, lack of association of SSB frequency with adiposity in a non-Western setting with low SSB consumption suggests that the role of SSB in adiposity appears to be minor.

AbstractBackground:A correlation between adiposity and post-exercise autonomic regulation has been established in overweight and obese children. However, little information exists about this link in non-obese youth. The main purpose of this cross-sectional study was to describe the relationship between body fat percentage (BFP) and heart rate recovery after exercise [post-exercise heart rate (PEHR)], a marker of autonomic regulation, in normal-weight children and adolescents.Methods:We evaluated the body composition of 183 children and adolescents (age 15.0±2.3 years; 132 boys and 51 girls) who performed a maximal graded exercise test on a treadmill, with the heart rate monitored during and immediately after exercise.Results:A strong positive trend was observed in the association between BFP and PEHR (r=0.14; p=0.06). Hierarchical multiple regression revealed that our model explained 18.3% of the variance in PEHR (p=0.00), yet BFP accounted for only 0.9% of the variability in PEHR (p=0.16). The evaluation of the contribution of each independent variable revealed that only two variables made a unique statistically significant contribution to our model (p<0.01), with age contributing 38.7% to our model (p=0.00) while gender accounted for an additional 25.5% (p=0.01). Neither BFP (14.4%; p=0.16) nor cardiorespiratory endurance (5.0%, p=0.60) made a significant unique contribution to the model.Conclusions:Body fatness seems to poorly predict PEHR in our sample of non-obese children and adolescents, while non-modifiable variables (age and gender) were demonstrated as strong predictors of heart rate recovery. The low amount of body fat reported in non-obese young participants was perhaps too small to cause disturbances in autonomic nervous system regulation.

Fat Reduction

Obesity is a medical condition that presents excessive fat accumulation with high risk of serious chronic diseases. The aim of this clinical trial is to investigate the anti-obesity effects of Cornus officinalis (CO) and Ribes fasciculatum (RF) on body fat reduction in Korean overweight women. A total of 147 overweight female participants enrolled in double-blinded clinical trial for 12 weeks and 76 participants completed the clinical study. Participants were treated with four CO and RF mixture (COEC; 400 mg per tablet) or four placebo tablets once a day. Obesity associated parameters (body weight, body mass index (BMI), waist circumference, waist-to-hip ratio, body fat percentage and body fat mass) and safety assessment were analyzed. After 12 weeks of COEC treatment, primary outcomes such as body fat percentage (0.76% vs. 0.01%; p = 0.022) and mass (1.1 kg vs. 0.5 kg; p = 0.049) were significantly decreased. In addition, the results were statistically significant between the COEC and placebo groups, strongly indicated that COEC had anti-obesity effects on overweight women. Secondary outcomes—including body weight, waist and hip circumference, waist-to-hip ratio, body mass index and computed tomography measurement of visceral fat area, subcutaneous fat area, total abdominal fat area and visceral-to-subcutaneous fat ratio—were reduced in COEC-treated group, but no statistical differences were found between the COEC and placebo groups. The safety assessment did not differ between the two groups. These results suggest that treatment of COEC extract reduces body fat percentage and mass in Korean overweight women, indicating it as a protective functional agent for obesity.

Background: The Queens College Step Test is used to determine aerobic fitness. Peak Expiratory Flow Rate (PEFR) is the maximum rate of forceful exhalation following full inspiration. PEFR primarily reflects bronchial airflow and depends on the voluntary effort and muscular strength of the individual. Studies that correlate ventilatory capacity with body fat percentage are rare in published literature in Nepalese settings. Body fat percentage is regarded as a better indicator of obesity recently. Hence, this study aims to find an association between post-exercise change in PEFR and body adiposity in the context of Nepal. Methods: A cross-sectional study was carried out from 20th July 2019 to 15th November in the laboratory of Clinical Physiology of Maharajgunj Medical Campus. Body fat percentage was measured by using OMRON BF 214.  Pre-exercise PEFR of each subject was recorded by using Wright’s peak flow meter. Post-exercise PEFR was also recorded after three minutes of Queen’s College step test, which is the submaximal exercise test, and change in PEFR was calculated and correlated with body fat percentage. Result: The study showed a negative correlation of change in PEFR with body fat percentage (r=-0.324; P<0.001). A significant difference (P = 0.002) was observed between different quartiles of body fat percentage. A highly significant difference (P = 0.003) was noted with the first and fourth quartiles. Conclusion: Less ventilatory adjustment in response to exercise was noted in subjects with more body fat percentage compared to those with less body fat percentage.

El objetivo del trabajo fue describir y comparar las características físicas y antropométricas de 25 gimnastas pertenecientes al grupo de tecnificación de la Federación Extremeña de Gimnasia. Estas gimnastas fueron clasificadas según modalidad gimnástica: artística femenina (GAF) (n=13) y gimnasia rítmica (GR) (n=12). Las variables dependientes incluyen valoraciones del porcentaje graso, a través de una báscula electrónica de columna con tallímetro (SECA 220cm); perímetros corporales, a través de un plicómetro (Holtain); diámetros y pruebas específicas de flexibilidad, a través de cinta métrica (CM 3m); frecuencia cardíaca, a través del test de Ruffier y uso de pulsómetro (Polar F6); fuerza isométrica del tren inferior, donde se utilizó una célula de carga (SSMAJ 5000N), y la capacidad de salto, a través de una plataforma de contacto (Lafayette CVP A73). Los resultados concluyen que GAF obtiene mejor resultado en las pruebas de flexibilidad (p<.05). Además, el grupo GR cuanto menor porcentaje graso posee mayor capacidad de salto SJ (r=-.774; p<.01) y CMJ (r=-.600; p<.05). En cambio, el grupo GAF cuanto mayor índice de masa corporal menor es su flexibilidad (p<.01). Se concluye que existen diferencias en composición corporal y pruebas físicas entre las modalidades gimnásticas femeninas de artística y rítmica, además de encontrar relaciones entre el rendimiento de dichas pruebas y variables antropométricas. Palabra clave: gimnasia, características antropométricas, flexibilidad, fuerza isométrica, salto.Abstract: The aim of our research was to describe the physical and anthropometric characteristics of 25 gymnasts from the talent identification program of the Extremeña Gymnastics Federation. Subjects were classified according to their specialty: women‘s artistic gymnastic (WAG) and rhythmic gymnastics (RG). The dependent variables include body fat percentage through an electronic scale column with stadiometer (SECA 220cm); body circumferences through a plicometer (Holtain); body diameters and specific tests of flexibility through a tape (CM 3m); a heart rate through Ruffier test and a heart rate monitor (Polar F6); isometric strength of lower extremities through a load cell (SSMAJ 5000N); and jumping ability through a contact mat (Lafayette CVP A73). The results concluded that the WAG group got the best results in flexibility tests (p<.05). Also, the RG group had lower body fat percentage and greater SJ jump ability (r=-.774; p<.01) and CMJ (r=-.600; p<.05). However, the WAG group showed a negative relation between body mass index and flexibility (p<.01). We conclude that there are differences in body composition and physical tests between the specialties/styles of women’s artistic gymnastics and female rhythmic gymnastics; we also found relationships between the performance of such tests and anthropometric variables.Key words: gymnastics, anthropometric characteristics, flexibility, isometric strength, jump.

The benefits of Tai Chi and Wai Tan Kung exercises on cardiopulmonary endurance and body composition have become a controversial issue. The survey analytical computational study was performed to investigate the differences in cardiopulmonary endurance and body composition among elderly members of Tai Chi, Wai Tan Kung, and elderly sedentary. The study involved 10 elderly members of Tai Chi, 10 elderly members of Wai Tan Kung, and 10 elderly sedentary. The Astrand-Rhyming’s step test was conducted to measure the cardiopulmonary endurance. While the measurement of body composition (body fat percentage) was done using a skinfold caliper. The data were analyzed with an unpaired t-test(p<0.05). The results of the study indicated that cardiopulmonary endurance (VO2 max) and body composition (body fat percentage) of Tai Chi elderly members were the best of both Wai Tan Kung elderly members and of elderly sedentary; while cardiopulmonary endurance and body composition of Wai Tan Kung elderly members were better than those of elderly sedentary.

AbstractBackground:Physical inactivity contributes to many health issues. The WHO-recommended physical activity for adolescents encompasses aerobic, resistance, and bone strengthening exercises aimed at achieving health-related physical fitness. Heart rate variability (HRV) and maximal aerobic capacity (VO2max) are considered as noninvasive measures of cardiovascular health. The objective of this study is to compare the effect of structured and unstructured physical training on maximal aerobic capacity and HRV among adolescents.Methods:We designed a single blinded, parallel, randomized active-controlled trial (Registration No. CTRI/2013/08/003897) to compare the physiological effects of 6 months of globally recommended structured physical activity (SPA), with that of unstructured physical activity (USPA) in healthy school-going adolescents. We recruited 439 healthy student volunteers (boys: 250, girls: 189) in the age group of 12–17 years. Randomization across the groups was done using age and gender stratified randomization method, and the participants were divided into two groups: SPA (n=219, boys: 117, girls: 102) and USPA (n=220, boys: 119, girls: 101). Depending on their training status and gender the participants in both SPA and USPA groups were further subdivided into the following four sub-groups: SPA athlete boys (n=22) and girls (n=17), SPA nonathlete boys (n=95) and girls (n=85), USPA athlete boys (n=23) and girls (n=17), and USPA nonathlete boys (n=96) and girls (n=84).Results:We recorded HRV, body fat%, and VO2 max using Rockport Walk Fitness test before and after the intervention. Maximum aerobic capacity and heart rate variability increased significantly while heart rate, systolic blood pressure, diastolic blood pressure, and body fat percentage decreased significantly after both SPA and USPA intervention. However, the improvement was more in SPA as compared to USPA.Conclusions:SPA is more beneficial for improving cardiorespiratory fitness, HRV, and reducing body fat percentage in terms of magnitude than USPA in adolescent individuals irrespective of their gender and sports activities.

Health Related Fitness

The possibility of predicting health related fitness using questions on occupational and leisure activity was explored in 172 men and 178 women. ANOVA and multiple regression equations related questionnaire responses to objective fitness measures including body mass index, circumferences, skinfolds, body fat, blood glucose, uric acid, total cholesterol, HDL-cholesterol and triglycerides, PWC150, blood pressures, and resting heart rate. Reported occupational activities bore little relationship to health related fitness. Self-perceptions of moderately frequent and moderately intense leisure activity, plus at least average perceived fitness relative to age-matched peers, were associated with a favourable body fat content and lipid profile, whereas indicators of cardiovascular health (a low resting heart rate and a high PWC150) were linked with perceptions of frequent and intense activity, plus a perceived fitness level higher than that of a peer reference group. Based on these findings, a simple scoring of reported activity for use in fitness counseling is suggested. Key words: cardiovascular fitness, leisure activity, metabolic fitness, occupational activity, perceived activity
