(School of Physical Education,Shenzhen University,Shenzhen 518061,China) Abstract: This study aimed to investigate the differences of ppTAG reduction induced by acute exercise of different modes (continuous/accumulated) in young people with or without exercise habits, so as to provide experimental evidence for ppTAG management. 30 female college students aged (20.2 ± 1.2) years with or without exercise habits respectively were recruited. Three tests in random order (sedentary control, continuous exercise, and accumulated exercise) were carried out, and the interval of each test is 5 to 7days. Then a high fat meal were provided and ppTAG were monitored during 5 hours after the meal. Both continuous exercise and accumulated exercise were carried out on treadmill with 65% VO2max exercise intensity, and continuous exercise lasting for 30 minutes for one bout, but accumulated exercise was completed in 5 bouts, 6 minutes each bout, with an interval of 2 hours. The results showed that: compared with sedentary control, both continuous exercise and accumulated exercise could significantly reduce ppTAG (P < 0.05), and accumulated exercise was stronger than continuous exercise (P < 0.05). The fasting TAG in the next morning for three groups decreased in turn (P < 0.05). There was no significant difference in ppTAG reduction induced by continuous exercise or accumulated exercise between the habitual exercisers and non-habitual exercisers (P > 0.05). It can be concluded that accumulated exercise has a more significant effect on reducing ppTAG than one bout continuous exercise with equal exercise volume, and the effect of reducing ppTAG, after exercise may be an acute response to exercise which is not related with exercise habits.
