Blood Lactate Level and Anaerobic Function Response to Core Muscle High Intensity Interval Training

The purpose of this study is to study the anaerobic performance response and blood lactate level following core muscle high-intensity interval training in male swimmers. All subjects were randomly divided into two groups: one requested to receive high-intensity interval training group (n = 10), and a control group received a swimming training program only (n = 10). The experimental group performed three days per week of training for six weeks. Before, after weeks 4 and 6, anaerobic function responses were tested with a 30-s maximum cycle test and blood lactate concentration tests at the fingertip with measurement before and immediately after the Wingate anaerobic test. The study result showed significant improvements in anaerobic function response in the experimental group after week 4 and after week 6. In addition, the results of the 30-second Wingate anaerobic test-induced blood lactate levels in experimental groups were significantly able to control the blood lactate levels. The conclusions of this study indicate that the experimental group had better control of anaerobic function and blood lactate levels than the control group after 6 weeks. However, the training in this study can be used by coaches and trainers to plan and guide swimmers in setting goals for appropriate adaptations.
