Abstract

Heart disease and respiratory disorders are major health issues in modern society, with sedentary behavior increasing the risk of heart disease, reducing lung capacity, and causing cardiovascular diseases and obesity. Many workers face limited time for exercise, prompting this study to evaluate and compare the effects of a 60-minute walking exercise and stretching on heart and lung strengthening in Yogyakarta. Using an experimental design, the study targeted workers aged 20-40 years who were healthy, office-based with sedentary behavior, had normal body weight, and were willing to participate in all provided exercises. Data were collected using questionnaires and the Cooper test to measure cardiorespiratory endurance over 12 minutes, and a t-test was conducted to compare pre-test and post-test scores. Results from 30 participants showed that the t-value of 5.448 exceeded the t-table value (df 14) of 1.76131, with a significance level of 0.000 < 0.05. This indicates that both the 60-minute walking exercise and stretching were proven effective in improving heart and lung strength.

Abstract

This study aims to analyze the effect of exercise therapy on knee joint function in elderly users of contemporary wellness training (line dancing). The analysis was conducted on pre-elderly elderly individuals aged 45-59 who actively participated in Line Dance training at Lippo Plaza Yogyakarta. This study used a descriptive quantitative method with 19 elderly users of contemporary wellness training (line dancing). Data collection was conducted through observation, documentation, and Range of Motion (ROM) measurements using a goniometer over eight sessions. The research instrument used a measuring tool with proven validity and reliability. The data analysis technique used SPSS software version 27 with data normality testing using Shapiro-Wilk. The results of the study indicate that: (1) The implementation of Line Dance has fulfilled the structured training components and is in accordance with the physical needs of the elderly; (2) Line Dance has contributed positively to improving the function of knee joint movement in the elderly. This is shown through changes in the Range of Motion (ROM) of the knee joint gradually in the flexion movement increasing by 12.43º and extension decreasing by 8.4º during eight meetings; (3) Contemporary wellness Line Dance can be a form of contemporary wellness-based exercise therapy carried out with light-moderate intensity (50% - 70%) with a duration of 60-90 minutes and carried out with a frequency of 2-3 times in 1 week. Thus, it can be concluded that Line Dance can be an exercise therapy to improve the function of knee joint movement.

Abstract

Combinations of roselle, lemongrass, and ginger have potential as natural antioxidant sources. Previous studies have evaluated similar combinations using the DPPH method; therefore, evaluation with an alternative method is needed to obtain a more comprehensive picture of antioxidant activity. This study aimed to determine the total phenolic and flavonoid contents and to evaluate the antioxidant activity of a roselle:lemongrass:ginger (2:1:1) combination extract using the FRAP (Ferric Reducing Antioxidant Power) method as an electron-transfer-based approach. Extraction was carried out with 70% ethanol; total phenolic content was measured by the Folin-Ciocalteu method, total flavonoid content by the AlCl₃ method, and reducing capacity was determined by the FRAP method expressed as ascorbic acid equivalents (mg AAE/g). The results showed that the total phenolic content of Formulation was 107.60±7.39 mg GAE/g and the total flavonoid content was 6.90±0.24 mg QE/g, both higher than those of the single roselle extract (63.43±0.52 mg GAE/g; 4.69±0.80 mg QE/g). The FRAP capacity of Formulation reached 135.34±37.75 mg AAE/g (n=2), relatively higher than that of the formulation with added jasmine. The increase in phenolic and flavonoid contents in Formulation was consistent with better reducing capacity, supporting the contribution of phenolic compounds to electron-transfer-based antioxidant activity. These findings conclude that the 2:1:1 ratio has potential as a natural antioxidant source based on electron transfer, but still requires ratio optimization through a mixture design approach and fractionation before being developed as a functional food raw material.
