Abstract

This study aims to knowing the differences in effectiveness of the timing cold water immersion against the onset of delayed onset muscle soreness after submaximal exercise. This research is an experimental study with posttest-only with control group design. The pain of delayed onset muscle soreness measured by Visual Analog Scale. The subjects were 30 samples, which split into 3 groups. Data analysis to determine the result of this study used the one way ANOVA with α determined at 0.05. The result of this study indicate that there are significant differences in each group, the group that received the immersion had a lower pain scale than the control group, also the group that was treated 1 hour after exercise showed better results than the 4 hours, CWI after 1 hour after exercise can inhibit migration of neutrophils which are the main cells of secondary damage that will induce pain. The conclusion of this study is cold water immersion after 1 hour after exercise is better than the 4 hours.

Abstract

One of the non-communicable diseases found in all regions of the world, including rural areas, is Diabetes Mellitus, caused by a chronic metabolic disorder characterized by increased glucose levels in the blood due to impaired insulin secretion. Diabetic neuropathy is damage to peripheral nerves or peripheral nerves commonly experienced by people with type 2 diabetes mellitus, characterized by excessive pain and decreased sensitivity to touch. The purpose of this study was to determine the self-management carried out by diabetic patients in the city of Surakarta. This study is cross-sectional with a sample of 99 respondents using a purposive sampling technique with inclusion criteria of 40-60 years of age and type 2 DM patients. The tests carried out were the inter-class intercorrelation coefficient test and the Kruskal–Wallis test using SPSS. The results of this study mean the highest interclass correlation coefficient was the diabetic foot care subclass with a value of 0.773 representing the homogeneity of the DMSQ questions and a confidence interval of 0.687-0.839 at 95% with a significance of p 0.05 in each subclass.

Abstract

Military preparation requires aerobic capacity (VO2max) and physical condition. Studies show that Indonesian Air Force personnel are overweight (34.9%) and obese (9.1%), which may impede task performance. This study examines how stair ascending and descending improve aerobic capacity (VO2 max) in Skadron Pendidikan 404 (Skadik 404) cadets, with BMI as a supportive factor. A quasi-experimental study included 40 cadets aged 19-22 with a BMI of 18.5-24.9 kg/m², divided into four groups: POK 1 (stair climbing), POK 2 (stair descending), POK 3 (stair climbing), and POK 4 (stair descending). This study uses 'POK' to refer to each study group. Data was collected using the 12-minute Cooper Test to measure VO2max. The data was analyzed using pairwise t-tests and two-way ANOVA with 5% significance. The study found significant differences in aerobic capacity (p < 0.05), with the stair-climbing group achieving larger VO₂max improvements than the descending group. These results show that army students may benefit more from stair climbing for aerobic training. This study supports military fitness studies by showing that stair climbing is better than stair descending and suggesting time-efficient, high-intensity training routines to improve soldiers' physical readiness.
