Comparison of electrolyte levels and immune function markers in saliva, sweat, urine and/or plasma in resting and exercising humans
Various markers can be used to assess how the body responds to exercise and to examine the effects of training regimes. Some of the best ways to do this require invasive procedures such as biopsies and blood sampling. However, it may be easier to analyse urine, saliva and/or sweat samples – especially for certain electrolytes (salts), hormones and immune markers – and this may increase the likelihood of getting more participants for exercise studies. Therefore, the aim of this study is to compare electrolyte, hormones and immune markers in various bodily fluids (saliva, sweat, urine and blood); we will examine responses in males vs. females and rest vs. exercise.
We have also examined validity and reliability of different methods of saliva sampling (unstimulated whole saliva, stimulated whole saliva and cotton bud methods).
