Effect of Pre-Exercise Loading Diet in Different Digital Ratio Subject on Aerobic Level of Exercise Performance

Abstract

This study based on a random sample from a Prospective Cohort study including one hundred healthy young untrained male volunteers, with mean age ± standard deviation (SD) of 22.820 ± 2.271 years. The aim of this study was to examine the effects of pre-exercise carbohydrate diet for untrained subjects on exercise performance. The parameters that have been measured were: Index and ring fingers length of both right and left hand, body weight, height, waist and hip circumferences, body composition (including: fat, muscle and water) and exercise performance (including: time, distance, calories and calculated calories expenditure). Participants were divided into three subgroups according to their digit ratio; 36 subject with (high D2:D4 1.036-0.980), 37 subject with (moderate D2:D4 0.979-0.954) and 27 subject with (Low D2:D4 0.950-0.912). The result showed that distance, time, calorie expenditure and calculated calorie expenditure were significantly higher after diet intake (150gm and 250gm respectively) in comparison with fasting state among participant during briskly walking on treadmill. As well as, the effect appear more obviously among low digit ratio group in comparison with that of moderate and high digit ratio group respectively.
