Two cycling participants, whose data were included in the analysis, reported feelings of nausea during the SS trial upon ingestion of the salt capsules; one of these participants also reported cramping later in the evening after completion of the SS trial. One cycling participant, whose data were not included in analysis, was unable to complete the SS trial due to nausea and vomiting upon ingestion of the first salt capsule at the beginning of the test.
