EFFECTS OF HIGH-INTENSITY CYCLING PERFORMED AFTER RESISTANCE TRAINING ON STRENGTH AND HYPERTROPHY
Tsitkanou S1, Terzis G3.
METHOD
– 22 young men; 8 weeks of training (2x per week)
(a) resistance training (RE; N = 11)
(b) resistance training plus high-intensity interval cycling (REC; N = 11)
CONCLUSIONS
– High-intensity interval cycling performed after heavy-resistance exercise may not inhibit resistance exercise-induced muscle strength/hypertrophy after 2 months of training
– The addition of high-intensity cycling after heavy-resistance exercise may decrease RFD partly due to muscle architectural changes
AEROBIC EXERCISE AUGMENTS MUSCLE TRANSCRIPTIONS PROFILE OF RESISTANCE EXERCISE
Lundberg TR1, Fernandez-Gonzalo R2, Tesch PA3, Rullman E2, Gustafsson T2.
INTRODUCTION
– Recent reports suggest that aerobic exercise may boost the hypertrophic response to short-term resistance training
DESIGN
– 10 moderately trained men performed ~45 min cycling on one leg followed by 4×7 maximal knee extensions for each leg, 15 min later
– Thus, one limb performed aerobic and resistance exercise (AE+RE), while the opposing leg did resistance exercise only (RE)
CONCLUSIONS
(1) Aerobic exercise alters the skeletal muscle transcriptional signature of resistance exercise to initiate important gene programs promoting both myofiber growth and improved oxidative capacity
(2) These results provide novel insight into human muscle adaptations to diverse exercise modes and offer the very first genomic basis explaining how aerobic exercise may augment, rather than compromise muscle growth induced by resistance exercise
