Abstract

Kecepatan adalah aset utama atlet renang. Penelitian terbaru menunjukkan variabel fleksibilitas dan kekuatan otot lengan sangat memengaruhi kecepatan renang individu. Penelitian ini bertujuan mengetahui hubungan antara fleksibilitas dan kekuatan otot lengan pada atlet renang gaya bebas di Makassar. Desain penelitian ini adalah cross sectional dengan jumlah sampel 20 orang atlet yang berusia 12-18 tahun. Variabel independen yang diukur adalah fleksibilitas dan kekuatan otot lengan. Variabel dependen yang diukur adalah kecepatan renang melalui tes renang gaya bebas 25 meter. Analisis bivariat digunakan untuk menganalisis hubungan fleksibilitas dan kekuatan otot lengan dengan kecepatan pada atlet renang. Hasil penelitian menunjukkan adanya korelasi positif antara fleksibilitas dengan kecepatan (p=0,001; R2=0,512) dan kekuatan otot lengan dengan kecepatan (p=0,001; R2=0,746). Disimpulkan bahwa semakin tinggi nilai fleksibilitas, semakin tinggi kecepatan renang. Semakin besar nilai kekuatan otot lengan, semakin tinggi kecepatan renang.

Abstract

This study aims to determine changes in ET-1 and F2-isoprostane levels after a 30 km cycling event in the Makassar cycling community. This study used a pre-experimental with one group pretest-posttest design on 30 male cyclists aged 30-60 years. The sampling technique used is the purposive sampling method. The pretest was carried out the day before the 30 km cycling event, then the post-test was carried out 2 hours after the cycling event. Blood testing is done with an ELISA Kit. Data were analyzed using the Wilcoxon test to see changes in ET-1 and F2-isoprostane levels after cycling events. The correlation of changes in ET-1 and F2-isoprostane levels was analyzed using the Spearman test. The results of this study found that the 30 km cycling event had no significant effect on changes in levels of ET-1 (p=0.082) and F2-isoprostane, which means that it has no potential to increase the body's oxidative stress (p=0.688). Changes in ET-1 levels did not correlate with changes in F2-isoprostane levels which showed no association with impaired cardiovascular function (p=0.102).

Abstract

This study aims to determine changes in levels of Creatine Kinase-Myocardial Band and F2-Isoprostane after a 30 km cycling event. This is a pre-experimental study on 30 subjects of male cyclists aged 30-60 years taken by purposive sampling method. The pretest was carried out the day before the 30 km cycling event, then the post-test was carried out 2 hours after the cycling event. Blood testing was done with an ELISA Kit. Data analysis using the Wilcoxon test showed significant changes in Creatine Kinase-Myocardial Band levels after a 30 km cycling event (p=0.003). Meanwhile, there was no significant change in F2-Isoprostane levels after the event (p=0.688). The results of the Spearman test showed that there was a correlation between changes in levels of creatine kinase-myocardial band with changes in levels of F2-Isoprostane (p=0.042).

Abstract

This study looks at the changes in MDA and LDH levels after a 30 km cycling event in the Makassar cycling community. This research is a pre-experimental with a one-group pretest-posttest design on 30 male cyclists aged 30-60 years. The pre-test was carried out the day before the cycling event, and then the post-test was carried out 2 hours after the 30 km cycling event. Blood samples were tested using the ELISA Kit. Data were analyzed using the Wilcoxon test to see the effect of a 30 km cycling event on changes in MDA and LDH levels. Spearman correlation test to see the correlation between changes in MDA levels and LDH. The results of the study found that the 30 km cycling event had a significant effect on changes in MDA levels due to lipid peroxidation (p<0.05) and a significant effect on changes in LDH levels due to increased lactate secretion (p<0.05). There was no significant correlation between changes in MDA and LDH levels (p=0.60) with a negative correlation, which means that the more significant the change in MDA levels, the lower the LDH level.

Abstract

This study aims to determine changes in Nitric Oxide (NO) and F2-Isoprostane levels after a 30 km cycling event in the Makassar cycling community. This research was a pre-experimental study with a one-group pretest & post-test design with 30 cyclists as subjects in the city of Makassar, men aged 30-60 years. Blood sampling was carried out pre-event and post-event cycling as far as 30 Km. Measurement of F2-Isoprostane & Nitric Oxide levels using the ELISA method. Data analysis used the Wilcoxon test to see changes in Nitric Oxide (NO)  and F2-Isoprostane levels after participating in a 30 Km cycling event. Data analysis using the Mann-Whitney test was used to see differences in changes in Nitric Oxide (NO)  and F2-Isoprostane levels in the age group, average speed, exercise category, BMI, and smokers. Spearman test to see the correlation of changes in Nitric Oxide (NO)  and F2-Isoprostane levels. The results of this study found that the 30 km cycling event had a significant effect on changes in Nitric Oxide (NO)  levels which could improve the function of the vascular endothelium with p=0.0001. Meanwhile, the 30 km cycling event had no significant effect on changes in F2-Isoprostane levels, which meant that it had no risk of oxidative stress and tissue damage (p=0.688). There is no positive correlation between changes in Nitric Oxide (NO)  levels and changes in F2-Isoprostane levels, which means that changes in the repair of vascular endothelial function seem to suppress free radical production which leads to oxidative stress after cycling as far as 30 Km.
