Order effects of high-intensity intermittent and strength exercise on lipoprotein profile

Abstract

Purpose To compare the effects of the order of concurrent exercise (endurance plus strength or strength plus endurance) on lipoprotein profiles in men. Methods After the evaluation of maximum strength (one repetition maximum-1RM) in the half-squat and of aerobic fitness (maximal velocity in treadmill incremental test), 11 physically active male subjects underwent two randomized sessions composed of four sets of half-squat strength exercises until exhaustion (at 80 % of 1RM) and a 5-km run high-intensity intermittent exercise (1:1 min at V max), performed in different orders: (1) strength plus run (S-A) and inverse order, and run plus strength (A-S). Blood samples were collected before and immediately after the first exercise (Post-1) and after the second exercise (Post-2) in the intra-session sequence. Serum was analyzed for total cholesterol (TC) and its ratio, HDL-c and LDL-c, and triacylglycerol (TAG). Results There were effects of condition for TC, LDL-c, and TC/HDL, with greater values in the AS than SA (p \ 0.001 for all). For the delta analysis, there was an interaction effect for TAG, with greater delta-1 S-A than delta-1 AS (p = 0.035), and higher delta-1 S-A than delta-2 S-A (p = 0.001); for LDL-c, with higher delta-1 S-A values than delta-2 S-A (p = 0.010); and for TC, with higher delta-1 S-A values than delta-2 S-A (p = 0.038). Conclusion We conclude that there are no differences between the order of acute high-intensity intermittent run plus strength exercises regarding modulation of the lipoprotein profile in healthy, physically active men.

Body composition and lipid profile of regular recreational table tennis participants: a cross-sectional study of older adult men

“…It seems that recreational table tennis, due to its intermittent activities that dominantly depends on ~ 96% of aerobic energy [23], could also increase the ability of skeletal muscles to use the carbohydrates and fats, leading to decreasing the plasma lipids. Recreational table tennis possibly decreases LDL-C and increases HDL-C and HDL-C/LDL-C ratio due to removing plasma LDL-C and fat oxidation by increasing the activities of lipolytic, LPL and hepatic lipase enzymes [49,53]. Furthermore, recreational table tennis participants may be a consequence of increased formation of HDL from increased functionality of RCT process through enhanced capacity of plasma to promote cholesterol efflux, increased concentration of preβ1-HDL, and increased activity of Lecithin cholesterol acyl transferase (LCAT) [54].…”
