This study aims to determine how much influence aerobic exercise and weight training have on body fat and vital capacity. This study used an experimental method with a randomized control group pretest-posttest design. The population in this study were 68 female members at the Fitness Center, Faculty of Sport Science, Yogyakarta State University who participated in the weight loss program. The sample in this study was taken purposively by determining the number of members who participated in the training program with the criteria that active members were at least 2 months practicing before the treatment was carried out and women aged 18-25 years. Through these criteria, the sample obtained is as many as 54 people. Of the 54 people, they were divided randomly into three groups, namely the aerobic exercise group of 18 people, the weight training group of 18 people, and the control group of 18 people. The instrument used to measure and collect body fat data used a skinfold caliper, while the vital lung capacity was measured using a spirometer with a Vitalograph brand. The data analysis technique used the normality test, namely the Kolmogorov-Smirnov Test. This test is carried out to determine whether the data has a normal distribution. The homogeneity test used the Levene's Test with the F test. To test the research hypothesis, it was done using Analysis of Variance (ANOVA). This test was conducted to determine the difference in the mean value of the variables between the pretest and posttest in the experimental group. The results of the research analysis showed that aerobic exercise can reduce body fat by 4.651% and increase the vital lung capacity of members at the Fitness Center by 0.2167 liters / BTPS. Weight training can reduce body fat by 2.969%. Weight training can increase the vital capacity of the lungs by 0.1583 liters / BTPS. Aerobic exercise can reduce body fat by 1.68617% higher than weight training. Aerobic exercise can increase the ability of vital lung capacity 0.05833 liters / BTPS higher than weight training. Pengaruh latihan aerobik dan latihan beban terhadap lemak tubuh dan kapasitas vital paru AbstrakPenelitian ini bertujuan untuk mengetahui seberapa besar pengaruh latihan aerobik dan latihan beban terhadap lemak tubuh dan kapasitas vital.

High-intensity exercise exercises in the exercise process use enormous amounts of muscle glycocal energy to strengthen adipose tissue into energy acids, energy requirements balanced with oxygen demand that will improve pulmonary performance and physiology. Weight-adjusting exercises are adjusted to the adaptation and physiology of muscles, increased muscle development and physiological muscles and muscles increases into more so that the energy process increases both muscle glycogen and increased fat oxidation. In this study the sample will be divided into 2 groups, group I will be given High intensity interval training, group II will be given Circuit weight training, both groups aim to reduce the percentage of body fat and increase the vital capacity of the lung. This study measures the pre and post test results so that it will be measured before treatment and after treatment after the exercise program for 6 weeks. Samples will be measured using Bioelectrical Impedance Analisys to measure the percentage of body fat and Spirometry to measure vital pulmonary capacity.The results of the first group hypothesis test showed the value before the fat percentage of 21.75 and after training to be 19.46, then before the vital capacity of the lungs 2.32 and after training to 4.02.

Background: Obesity is known as one of the most important cardiovascular risk factors. Objectives: This quasi-experimental study was conducted to investigate the effect of an eight-week aerobic exercise and garlic extract use on the blood pressure, fat percentage, and lipid profile of patients with hypertension. Methods: A total of 50 men with a mean age of 53 ± 7.6 years were recruited from among obese patients with blood pressure. They were randomly divided into five groups of aerobic exercise, garlic extract, aerobic exercise plus garlic extract, placebo, and control. The experimental groups underwent aerobic exercise (3 sessions per week, each session for 35 - 60 min with a maximum heart rate of 50 - 75) or garlic extract supplementation (daily use of 6 g) for eight weeks. Blood samples were collected before interventions and 48 h after the last exercise session. Statistical analysis was done by the dependent t-test and ANCOVA. Results: Body weight, body fat percentage, systolic and diastolic blood pressures, and serum LDL significantly reduced in the aerobic exercise, garlic extract, and aerobic exercise plus garlic extract groups compared to the control group (P ≤ 0.05). Aerobic exercise and aerobic exercise plus garlic extract groups showed a significant decrease in total cholesterol level and serum triglyceride and an increase in serum HDL compared to the control group (P ≤ 0.05). Aerobic exercise plus garlic extract group indicated a higher increase in serum HDL and a higher decrease in the body weight, body fat percentage, and serum LDL compared with the control group (P ≤ 0.05). Aerobic exercise plus garlic extract group indicated a higher serum LDL decrease compared to the aerobic exercise group (P ≤ 0.01). Conclusions: Both aerobic exercise and garlic extract seem to be able to improve obesity, lipid profile, and hypertension. However, their concurrent use has no additional effects on the blood pressure control although it mostly influences lipid profile and body composition.

Obesity is an increasing weight that exceeds the limits of physical and skeletal needs due to the excessive backfilling of body fat. Obesity is a predisposing factor for increasing triglyceride levels (TG) and insulin resistance status. Consumption of fiber, such as Tempeh Gembus can be an alternative treatment to lower TG levels and insulin resistance status. This research was aimed to prove the influence of processed Tempeh Gembus to TG levels and insulin resistance status. This research employed a pre-post randomized control group. The participants of this research are 40 women with pre-menopausal obesity which are divided into two groups: the control group which is given the daily standard diet treatment Isocaloric 30 kcal/kg of BW/day and the treatment group which is given the daily standard diet Isocaloric 30 kcal/kg of BW/day with the addition of processed Tempeh Gembus processed as much as 150 g/day for 28 days. The result show, giving Tempeh Gembus to the treatment group can lower the TG level (p = 0.010) and insulin resistance status (p = 0.000) significantly. The decreased levels of TG in the treatment group (-9.3±9.6 mg/dL) were higher compared to the decline in the control group (-2.90±4.43 mg/dL). Decreased insulin resistance status in the control group (- 0.60±0.51) is lower than the treatment group (-6.90±4.82). Based on the results above, consumption of 150 g/day of processed Tempeh Gembus for 28 days can lower TG levels

Background: Obesity and overweight are among serious global epidemics that significantly threaten human health, especially among women. Objectives: This study aimed to assess the concurrent effects of 6-week caffeine supplementation with moderate-intensity aerobic exercise on weight and body fat among overweight women. Methods: Thirty overweight females (age: 36.47 ± 6.48 years; BMI: 27.61 ± 1.54 kg/m2; mean ± SD) with a sedentary lifestyle were recruited to the study. The participants were randomly allocated to the experimental group, EC (exercise + caffeine) group, who took 100 milligrams of caffeine of the “API” brand supplement 30 minutes before exercise training (n = 15) or control group, EP (exercise + placebo) (n = 15). All participants performed moderate-intensity aerobic exercise with an intensity of 40 to 60% of heart rate reserve based on the individual's exercise test for 30 minutes, three days a week for six weeks. Measurements, including the percentage of body fat, waist circumference, and skinfold (suprailiac, abdominal), were done two times, at baseline and after six weeks of exercising. Results: There were no significant differences between control and experimental groups related to weight (P = 0.22), percentage body fat (P = 0.88), and other measurements after six weeks. Conclusions: 6 weeks of caffeine supplementation combined with moderate-intensity aerobic exercise without dietary interventions couldn’t make a significant reduction in weight and central or total body fat among overweight women.

Background and aims: It has recently been documented that obesity is a global problem in all age groups, so that it affects about 250 million people in the world, accounting for 7% of the world’s population. Adipose tissue has an important role in inducing lung dysfunction through production and secretion of adipokines such as leptin. The aim of this study was to investigate the effect of a period of aerobic training on lung function indices and serum leptin levels in obese men. Methods: A total of 23 untrained obese men in Arak were recruited voluntarily for the study and randomly assigned to obese aerobic training group (Ob-AT, n=12) (45.26±2.45 years, body mass index (BMI) of 31.81±0.77 kg/m2 ) and obese control group (Ob-Cnt, n=11) (47.03±3.36 years, BMI of 31.45±0.96 kg/m2). Another normal control group (No-Cnt, n = 9) was sampled from individuals with normal weight to compare at the base level (45.1±4.1 years, BMI of 24.63±0.45 kg/m2 ). The obese exercise group participated in 12 weeks of progressive aerobic training, 3 sessions a week, 1.5 hours per session. Body composition (CT scan), leptin levels and lung function were measured before and after exercise protocol. Results: The participants with normal weight had significantly lower leptin concentration (P=0.01) and a higher lung function (P=0.016) compared to the obese participants. Moreover, the results indicated that leptin and obesity had an inverse correlation with lung function indices (forced vital capacity [FVC] and forced expiratory volume in one second [FEV1 ]) (P≤0.05). After the aerobic activity, obesity (BMI, WHR, body fat) and lung function indices (FVC and FEV1 ) significantly decreased in the obese aerobic training group compared to the obese control group (P≤0.05). In contrast, leptin concentration significantly decreased after the aerobic exercise protocol (P=0.018). Conclusion: We found that leptin level decreased after 12 weeks of aerobic exercise in obese men and this decrease was associated with the increased lung function and profound changes in body fat. The obtained data suggest that 12-week aerobic exercise causes alterations in leptin level that plays a key role in improving lung function.

A serious environmental problem has occurred due to the negative impact of household waste. Lack of knowledge and awareness of waste processing must be improved through an effective counseling method provided for housewives. The aim of this research was to determine different counseling methods about garbage toward housewives’ knowledge about processing of the household waste. This research carried out on Kampung Pulo, Jakarta Timur on April 2013. A quasi-experiment method with a randomized control group pretest-posttest design was used. Counseling methods of demonstration and movie display were given in two different groups as the treatment. Instrument of knowledge test was used to collect data. The normality testing of Kolmogorov-Smirnov test and the Homogeneity testing of F-test at α = 0.05 resulted a normal distribution and homogenous data. The hypothesis testing of t-test showed t count > t table on 3.34 > 2.03 which rejected the H0, meaning that different knowledge level about processing of the household waste obtained from different method of counseling. It is concluded that, demonstration method was more effective than movie display to increase the housewives’ knowledge about processing of the household waste.

Purpose: the relationship between physical activity and airway health in children is not well understood. The purpose of this study was to determine whether 8 wk of high-intensity exercise training would improve airway responsiveness in prepubescent, nonasthmatic, inactive children. Methods: 16 healthy, prepubescent children were randomized [training group (TrG) n = 8, control group (ConG) n = 8]. Prior to and following 8 wk of training (or no training), children completed pulmonary function tests (PFTs): forced expiratory volume in 1 s (FEV1), forced vital capacity (FVC), forced expiratory flow at 25–75% of vital capacity (FEF25–75), and exhaled nitric oxide (FENO). Children completed an incremental cycle V̇o2max test, eucapnic voluntary hyperventilation (EVH), anthropometric tests, and blood tests to determine fasting blood glucose, total cholesterol, HDL, LDL, and triglycerides. Body fat percentage was determined using dual-energy X-ray absorptiometry pretraining and bioelectrical impedance pre- and posttraining. Results: there were no differences ( P > 0.05) in anthropometric measures or PFTs between TrG and ConG at baseline. In the TrG, there was a significant increase in V̇o2max (∼24%) and a decrease in total cholesterol (∼13%) and LDL cholesterol (∼35%) following training. There were improvements ( P < 0.05) in ΔFEV1 both postexercise (pre: −7.60 ± 2.10%, post: −1.10 ± 1.80%) and post-EVH (pre: −6.71 ± 2.21%, post: −1.41 ± 1.58%) with training. The ΔFEF25–75 pre-post exercise also improved with training (pre: −16.10 ± 2.10%, post: −6.80 ± 1.80%; P < 0.05). Lower baseline body fat percentages were associated with greater improvements in pre-post exercise ΔFEV1 following training ( r = −0.80, P < 0.05). Conclusion: these results suggest that in nonasthmatic prepubescent children, inactivity negatively impacts airway responsiveness, which can be improved with high-intensity training. Excess adiposity, however, may constrain these improvements.

Adiponectin regulates endothelial nitric oxide synthase in endothelial cells, and body fat loss by aerobic exercise training promotes adiponectin secretion. Recently, C1q/tumor necrosis factor-related proteins (CTRPs) have been identified as novel adipokines and are paralogs of adiponectin, but the association between exercise training-induced reduction of arterial stiffness and circulating CTRPs levels remains unclear. This study aimed to clarify whether the reduction of arterial stiffness in middle-aged and older adults is associated with the change in serum levels of CTRPs induced by exercise training. A total of 52 middle-aged and older participants were randomly divided into two groups: a training group ( n = 26) and a sedentary control group ( n = 26). Participants in the training group completed 8 wk of aerobic exercise training (60–70% peak oxygen uptake for 45 min, 3 days/wk). The reduction of percent whole body fat, abdominal visceral fat area, and carotid-femoral pulse-wave velocity (cfPWV) was significantly greater in the training group than in the control group ( P < 0.05). Moreover, the increase in serum adiponectin, CTRP3, and CTRP5 from baseline to 8 wk was significantly higher in the training group compared with the control group ( P < 0.05). Additionally, the training-induced change in cfPWV was negatively correlated with the training-induced change in serum adiponectin, CTRP3, and CTRP5 levels ( r = −0.51, r = −0.48, r = −0.42, respectively, P < 0.05), and increased plasma nitrite/nitrate level by exercise training was correlated only with adiponectin levels ( r = 0.41, P < 0.05). These results suggest that the exercise training-induced increase in serum CTRPs levels may be associated with the reduction of arterial stiffness in middle-aged and older adults.
