Study Design

Understand how the trial is structured, including allocation methods, masking strategies, primary purpose, and other design elements.

Allocation Method

RANDOMIZED

Intervention Model

CROSSOVER

Following a familiarization session, subjects will be assigned to an order for performing both an eccentric and a cycle (sham) session (i.e., crossover design, the order being randomized). These will be performed 3-7 days apart.

Primary Study Purpose

OTHER

Blinding Strategy

SINGLE

Investigators

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Cycling exercise

Cycling on a cycle ergometer instead of doing the experimental eccentric exercise.

Group Type ACTIVE_COMPARATOR

Cycle ergometer

Intervention Type OTHER

Individuals will do a randomized crossover intervention involving cycling (active control) exercise

Eccentric exercise

Perform 2 sets of maximal eccentric contractions as the single session exercise intervention.

Group Type EXPERIMENTAL

Eccentric Exercise

Intervention Type OTHER

Individuals will do a randomized crossover intervention involving maximal eccentric contractions (2 sets of 6 per leg; experimental condition)
