dc.description.abstract Form skipping has been used to help injured athletes progress to running. Because little research has been done on form-skipping mechanics, its justifi cation as a progression to running exercises is unclear. Objective: To compare groundreaction forces (GRF) during form skipping and running in healthy subjects at clinically relevant speeds, 1.75 m/s and 3.83 m/s, respectively. Design: Dependent t tests (α = .05). Setting: Sports-injury research center. Participants: 9 male college athletes (age 20 ± 1.33 years, mass 848.4 ± 43.24 N, height 1.80 ± 0.07 m). Main Outcome Measures: Average (Fz[subscript avg]) and maximum (Fz[subscript max]) vertical GRF and (Fy) braking impulse were compared. Results: Fz[subscript avg] and Fz[subscript max] were greater during running than during form skipping (P < .05). Braking impulses were not different (P > .05). Conclusions: It appears that Fz, but not the Fy, GRF might explain why form skipping might be an appropriate progression to running. en_US
