An energy-deficit (ED) diet increases lipid mobilisation, while endurance exercise improves lipid profile by promoting formation of high-density lipoproteins (HDLs) among moderately active population. However, it is not clear whether ED with high-intensity exercise training can improve lipid profiles. Therefore, 20 recreationally active males (20.3 +/- 2.7 years old with peak oxygen consumption (O(2)peak) of 2.8 +/- 0.2 L min(-1)) with HDL concentration of 1.44 +/- 0.32 mmol L-1, were evenly allocated to either an ED group (1590 +/- 79 kcal day(-1): 40% of total caloric omitted at lunchtime) or a control (CON) group (2570 +/- 139 kcal day(-1)). Participants in both groups performed high-intensity cycling at 90% O(2)peak at a constant workload for 8 min, 2 h after breakfast on day D-0, D-2, D-4, D-6, D-8 and D-10 (D-n is day number), after which blood samples were collected. In ED, compared to D-0, triglycerides (TG) decreased on D6-10 (p < .01) while total low-density lipoprotein (LDL), total cholesterol (TC) increased on D2-10, while HDL progressively increased on D6-10 (p = .01) with a final value of 1.67 +/- 0.24 mmol L-1. In CON, there were no changes in TG, TC and HDL while LDL was reduced on D8-10 (p = .01). Moreover, the proportions of TC/HDL and LDL/HDL increased in ED on D2-10 and D2-8 (p = .05), respectively, while LDL/HDL in CON was reduced on D8-10 (p = .01). In brief, 10 days of ED and a series of high-intensity exercise sessions show progressive elevation of HDL which suggest longer period is required to observe changes in lipid ratios.
