What did studies of high-intensity eccentric cycling find?

3

Studies of high-intensity eccentric cycling measured 3 outcomes; the most studied are muscle strength loss (1 study), creatine kinase (1) and IL-6 (1).

Muscle strength loss

upin humans1

1 study

  1. High-intensity eccentric cycling increases muscle strength loss in humans (100% POmax, measured at 1 day post-exercise) (8-22%).

    “Muscle strength loss at 1 day post-exercise (8-22%), peak soreness (10-62 mm) and creatine kinase activity (30-250 IU/L) after ECC-H were greater”

Creatine kinase

upin humans1

1 study

  1. High-intensity eccentric cycling increases creatine kinase in humans (100% POmax) (30-250 IU/L).

    “creatine kinase activity (30-250 IU/L) after ECC-H were greater (P < 0.05) than those after ECC-M and CONC-M.”
