Design outcomes

Primary

MeasureTime frame
Lower limb kinematics. Timepoint: Before intervention (pre-test). After the fatigue protocol. After application of the cooling spray. After the combined intervention (fatigue + cooling spray)Each measurement will be performed in a separate session, with at least 24 hours between sessions. Method of measurement: 3D motion analysis system with 12 infrared cameras (Vicon system) at a sampling frequency of 240 Hz.;Lower limb kinetics. Timepoint: Before intervention (pre-test). After the fatigue protocol. After application of the cooling spray. After the combined intervention (fatigue + cooling spray)Each measurement will be performed in a separate session, with at least 24 hours between sessions. Method of measurement: Kistler model force plate with a sampling frequency of 1000 Hz.;Electromyography of lower limb muscles. Timepoint: Before intervention (pre-test). After the fatigue protocol. After application of the cooling spray. After the combined intervention (fatigue + cooling spray)Each measurement will be performed in a separate session, with at least 24 hours between sessions. Method of measurement: Wireless surface electromyography system, Noraxon model.
