Effects of Vitamin B Complex on VO2max, Blood Lactate Concentration, and Heart Rate of Amateur Futsal Athletes
Abstract
COVID-19 is a viral disease that attacks the lungs, resulting in a decreased number of respiratory variables, especially VO2max. The decrease in VO2max causes a chain reaction affecting individual fitness variables, such as blood lactate concentration and heart rate, either directly or indirectly. Research regarding the effect of vitamin B complex on VO2max and blood lactate concentrations already exists, although not specifically described. This study aimed to compare the levels of VO2max, blood lactate concentration, and heart rate before and after the supplementation for futsal athletes. This study is expected to examine the restoration value when supplemented with vitamin B complex. The study involved 10 amateur futsal athletes having COVID-19 recovery record, ranging from the last 3 months until 12 months. The samples were divided into two treatment groups, namely the supplement group and the placebo group. The VO2max value was measured by using 2.4 km Cooper Test, while the the blood lactate concentration and heart rate were measured by using Accutrend® Plus and Polar® Heart Rate Sensor H10 and Polar® Heart Rate Monitor M400 during the 2.4 km Cooper test. The VO2max and blood concentration levels showed significant differences between before and after the supplementation (p<0.05), while the heart rate level did not show a significant difference (p<0.05). This study concludes that vitamin B complex supplementation has an effect on both VO2max and blood lactate concentration.
