AB [EN] Abstract: Background: To the authors’ knowledge, there have been no studies comparing the acuteresponses to “all out” efforts in concentric (isoinertial) vs. eccentric (isovelocity) cycling. Methods:After two familiarization sessions, 12 physically active men underwent the experimental protocolsconsisting of a 2-min warm-up and 8 maximal efforts of 5 s, separated by 55 s of active recoveryat 80 rpm , in concentric vs. eccentric cycling. Comparisons between protocols were conductedduring, immediately after, and 24-h post-sessions. Results: Mechanical (Work: 82,824 ± 6350 vs.60,602 ± 8904 J) and cardiometabolic responses (mean HR: 68.8 ± 6.6 vs. 51.3 ± 5.7% HRmax, lac-tate: 4.9 ± 2.1 vs. 1.8 ± 0.6 mmol/L) were larger in concentric cycling (p < 0.001). The perceptualresponses to both protocols were similarly low. Immediately after concentric cycling, vertical jumpwas potentiated (p = 0.028). Muscle soreness (VAS; p = 0.016) and thigh circumference (p = 0.045)were slightly increased only 24-h after eccentric cycling. Serum concentrations of CK, BAG3, andMMP-13 did not change significantly post-exercise. Conclusions: These results suggest the appro-priateness of the eccentric cycling protocol used as a time-efficient (i.e., ~60 kJ in 10 min) and safe(i.e., without exercise-induced muscle damage) alternative to be used with different populations infuture longitudinal interventions.
