Outcome measures
Primary outcome
The difference in total power output, in percentage, between the regular
cycling test and the combined arm- and leg cycling test will be the primary
endpoint of this study.
Secondary outcome
Secondary endpoints are differences in cycling efficiency, heart rate, muscle
activity, VO2 and RPE.
Background summary
Several types of sports rely on both arm- and leg propulsion to generate
propulsive power. Comparing situations in which the arms or legs have been
excluded, with combined arm- and leg propulsion points to an advantageous
effect of additional muscle mass in these sports. It is hypothesized that
adding arm propulsion to regular cycling also yields an increased power output.
Study objective
The primary objective is determining whether adding arm propulsion to regular
cycling increases total power output. Secondary objectives are determining
differences in cycling efficiency, heart rate, muscle activation, maximal
oxygen uptake (V02max) and rated perceived exertion (RPE) between regular
cycling and combined arm and leg cycling.
Study design
The study will be a randomized controlled cross-over trial with a total of 18
subjects. All subjects will perform a regular cycling test and a combined arm-
and leg cycling test.
Intervention
Both groups will perform a maximal power test with combined arm and leg
propulsion as intervention. Furthermore, the subjects will perform a maximal
power test for regular cycling as a control intervention.
Study burden and risks
Subjects will be asked to visit the researchers three times. Each visit lasts
about one hour. During the first visit, prior to any of the measurements, the
subjects will sign the informed consent. Subsequently, an intake interview to
determine the health of potential subjects will be performed, based on the
'baseline' in the CRF. If the potential subjects meet the inclusion criteria,
he or she will perform a familiarization trial with combined arm and leg
propulsion on the bicycle. During visit 2 and 3, the subjects will perform a
maximal power test, once with additional arm propulsion and once without, both
tests are separated by a resting period of one week. Only possible risk of this
study for subjects is temporary overuse of muscles or the cardiopulmonary
system.
