THE EFFECT OF HIGH INTENSITY INTERVAL TRAINING PERFORMED AT DIFFERENT TIMES OF DAY ON SOME PERFORMANCE PARAMETERS

Abstract

Athletes frequently employ high-intensity interval training (HIIT) to improve their performance. However, it is believed that it is critical to find the most efficient time period for performing training. The purpose of this study is to assess the effect of HIIT performed at different times of the day on various performance measures. Twelve male volunteers between the ages of 18 and 25, who had been exercising three days a week for at least three years and were studying at the faculty of sports sciences, participated in the study (age, 20,67± 1,07 years; body height, 174,25± 2,34 cm; 67,58± 3,02 kg; BMI 22,34±,89). Ten minutes warm-up + ten minutes HIIT were used in the research protocols. Additionally, two measurements were taken for the HIIT program, at various times of the day (09.00-11.00 a.m in the morning; 05.00- 07.00 p.m in the evening). Following each measurement, the volunteers' 30-meter sprint and T-line agility were assessed. Researchers found a statistically significant difference in the T-Test and 30 m sprint test performance between volunteers who completed the morning and evening HIIT programs (p < .05). T-Test and 30 m sprint test performances were seen greater in the evening hours. Based on the performance times of the T-Test and 30 m sprint test following the HIIT protocols performed in the morning, it was found that the HIIT protocol performed in the evening was more effective.
