Background: The elderly are very sensitive to disease and health problems. The lack of economic support, such as nutritious food as the source of energy, is the most often cause of health problems in the elderly. Reduced energy in the elderly's body causes the elderly's lack of physical activity, which affects the VO2max level of the elderly. Objective: The purpose of this study was to determine the relationship between physical activity and VO2max in the elderly. Methods: The research design was a cross-sectional study conducted in March 2021 with a population of all elderly in Banjar Tegalnarungan, Sobangan Village, Mengwi District, Bali, Indonesia, who met the inclusion and exclusion criteria. The sampling technique in this study was total sampling and obtained 38 people. This study used the International Physical Activity Questionnaire questionnaire and 6 Minutes Walking Test to measure the physical activity levels and VO2max, respectively. Data were analyzed by computer software, namely Somers'd to determine the relationship between physical activity and VO2max in the elderly. Results: The results showed a significant relationship between physical activity and VO2max, resulting in p < 0.001. Conclusion: There is a significant positive relationship between physical activity and VO2max in the elderly, which represents the higher the physical activity level, the higher VO2max belongs to the elderly.
Background: Elderly is assumed as a person who has been at the age of 60 and will be some alterations, physical alteration in term ages. The physical alteration that is commonly found in the elderly is a condition of the body mass index that will not be taken care of optimally due to the degenerative factor. Purpose: This study is aimed at proving the relation of body mass index towards the cardiorespiratory endurance along with the relation of physical activities towards the cardiorespiratory endurance. Methods: The study design was cross sectional with the population of the elderly in Banjar Alas Arum in which they qualified the inclusion and exclusion criteria. From the elderly that had been selected by means of purposive sampling, it was obtained 48 samples. The BMI was measured by formula calculation. The physical activity level was measured by the International Physical Activity Questionnaire and the cardiorespiratory endurance used 6 minutes walking test. The data were analyzed by software computer which was Somers’ D test. Results: The result of this study showed that by 48 the relation of BMI towards the cardiorespiratory endurance showed that the result of p was 0.000 (p<0.05). Concerning on the relation of physical activities towards the cardiorespiratory endurance shown that the result of p was 0.000 (p<0.05). Conclusion: It can be concluded that there is a significant relation in this study.
The number of elderly people in Indonesia from year to year continues to increase. With the increasing amount of elderly, it is followed by an increase in musculoskeletal complaints. The outbreak of Covid-19 has resulted in limited and disrupted physical activity and health services for the elderly. The elderly are a group at risk of death if infected with Covid-19 because there is a degenerative process and there are co-morbidities. Community service activities carried out at the Tresna Werdha Wana Seraya Social Home in Ketalanggu Village aims to provide health services so that during the Covid-19 pandemic the quality of life for the elderly will be better. Activities carried out using blood pressure screening methods and examination of musculoskeletal complaints as well as providing physiotherapy services related to musculoskeletal complaints such as exercise and infrared therapy for free to the elderly. The participation in this community service activity was 34 people with the most aged 66-70 years. The results of this activity are the presence of the elderly, and the results of blood pressure screening and services for musculoskeletal complaints in the elderly at the Tresna Werdha Wana Seraya Social Institution during the Covid-19 pandemic.
Background: Footwork training is important in coaching basic movements in badminton. This research aims to learn about the influence of footwork training on improving leg muscles strength. Methods: The study used a randomized pretest-posttest control group design. The participants consisted of 42 male badminton players of Universitas Pendidikan Ganesha, Bali, Indonesia, who split into two groups of footwork training (ten repetitions two sets (group 1) and five repetitions with four sets (group 2)). The coach gave the footwork exercise three times per week for 6 weeks to each group and measured the leg muscle strength using the dynamometer test. Results: The result of the within-group paired T-test before and after the training shows group 1 and group 2 (p<0.05). For group 1, the mean of leg muscle strength was 114.19±33.13 kg before the training and 183.19±33.56 kg after the training, with an increase of 60% (69 kg). On the other hand, for group 2, the mean score of leg muscle strength before the training was 113.05±31.30 kg and after the training was 141.10±34.91, with an increase of 25% (28 kg). The leg muscle strength difference between the groups before and after the training was tested using the independent T-test with a significant α=0.05. Comparing the differences of leg muscle strength for both the groups before the training was p= 0.90, and after the training was p=0.00. Conclusion: The conclusion is training badminton footwork ten repetition two sets better than five repetitions four sets to improve leg muscle strength.
Physical training is useful so that the body does not quickly experience excessive fatigue during strenuous physical activity, prevents degenerative diseases and improves health status. Physical training has an important role to maintain and improve the degree of physical fitness during this COVID-19 pandemic. This study aims to determine the Senam 2004 SKJ gymnastics training can improve physical fitness. This type of research is experimental with the randomized pretest posttest control group design. The sample of this study was 20 students of the Physiotherapy Study Program divided into 2 groups. Group 1 was given SKJ 2004 gymnastics training and Group 2 as a control group, with a frequency of exercise 3 times a week for 6 weeks. The component of physical fitness in this case is VO2Max measured by the Bleeps Test (MFT) instrument. The results of the study on age, height, weight and BMI were analyzed descriptively in both groups. Test the normality of the data using the Shapiro-Wilk Test and test the homogeneity of the data using the Levene Test. Intra-group differences in the mean of VO2Max were tested by paired t-test. The results of the different test with t-paired before and after training, the results obtained in Group 1 and Group 2 were significantly different (p <0.05). The results of the VO2Max test between the two groups before and after the training were tested using the t-independent sample test. The average VO2Max in both groups before training with p value = 0.27 (p>0.05) and after training with p value = 0.00 (p<0.05). In Group 1, the average VO2Max (L/m) before training was 26.45 and the average after training was 38.54 with a difference of 12.09 and a percentage increase of 45.70%. Meanwhile in Group 2, the average VO2Max before training was 25.51 and the average after training was 27.52 with a difference of 2.06 and the percentage increase was 8.07%. This shows that the treatment of group 1 and group 2 both gave a change effect. However, the improvement in group 1 was better than group 2. It was concluded that SKJ gymnastics training can improve physical fitness.
