Physiological diagnostics (activity sensors)
During each session, energy consumption was measured as a physiological parameter by using activity sensors (accelerometer Move II, Movisens GmbH, Karlsruhe, Germany). Move II consists of a triaxial acceleration sensor with a range of ± 8 g, a 64-Hz sampling frequency and a 12-bit resolution. The activity sensors were given to each participant before each session and were worn on the right side of the hip.
