	abstract = {Aim of the study was to investigate whether high-intensity interval cycling performed immediately after resistance training would inhibit muscle strength increase and hypertrophy expected from resistance training per se. Twenty-two young men were assigned into either resistance training (RE; N~=~11) or resistance training plus high-intensity interval cycling (REC; N~=~11). Lower body muscle strength and rate of force development (RFD), quadriceps cross-sectional area (CSA) and vastus lateralis muscle architecture, muscle fiber type composition and capillarization, and estimated aerobic capacity were evaluated before and after 8~weeks of training (2 times per week). Muscle strength and quadriceps CSA were significantly and similarly increased after both interventions. Fiber CSA increased significantly and similarly after both RE (type I: 13.6~{\textpm}~3.7\%, type IIA: 17.6~{\textpm}~4.4\%, type IIX: 23.2~{\textpm}~5.7\%, P~<~0.05) and REC (type I: 10.0~{\textpm}~2.7\%, type IIA: 14.8~{\textpm}~4.3\% type IIX: 20.8~{\textpm}~6.0\%, P~<~0.05). In contrast, RFD decreased and fascicle angle increased (P~<~0.05) only after REC. Capillary density and estimated aerobic capacity increased (P~<~0.05) only after REC. These results suggest that high-intensity interval cycling performed after heavy-resistance exercise may not inhibit resistance exercise-induced muscle strength/hypertrophy after 2~months of training, while it prompts aerobic capacity and muscle capillarization. The addition of high-intensity cycling after heavy-resistance exercise may decrease RFD partly due to muscle architectural changes.},
