Abstract
Aerobic exercise has demonstrated its own advantages. In addition to the benefits, exercise intensity plays an important role in determining the result of an exercise intervention. Currently, high-intensity continuous training is a well-known method of burning calories. The intensity of aerobic exercise can have long-term impacts on fitness development. (Kraus et al., 2002). This study aimed to evaluate physiological changes after high intensity continuous exercise training in adolescents. Participants were 30 Nakhon Phanom University students, 14 males and 16 females. They were healthy, aged 18.57 ± .50 years old, with a height of 163.88 ± 6.44 cm., and a weight of 54.79 ± 4.24 kg. The instruments used in the study comprised a high - intensity continuous training exercise program. High-intensity continuous exercise was performed every day for 1 hour 30 minutes for a period of 8 weeks and a test of health-related physical fitness. Body weight, resting pulse, BMI, muscle strength of arms and legs, and oxygen consumption performance were measured before and after-exercise training. Statistics used in data analysis were mean and standard deviation. The comparison of difference between the mean scores of the tests of health - related physical fitness administered before and after the high - intensity continuous training exercise program by using a paired - sample t - test for dependent samples. The statistical significance was predetermined at the .05 level. The results of the study showed that after 8 weeks of consistent high-intensity exercise training, body weight, body mass index, resting pulse, leg muscular strength, and oxygen consumption were significantly different. These results suggest that high-intensity continuous training leads to an increase in metabolic rate, resulting in increased carbohydrate and fat burning, which can lead to weight loss and physical fitness improvement in adolescents. Therefore, the aerobic exercise program should take into account the amount and intensity in accordance with the objectives of the exercise.
