Primary Outcome Measures
NameTimeMethod
<p>Blood sample:<br /><br>o Serum/plasma: cytokines, CRP, cortisol<br /><br>o *Homing* estimations: where do the immune cells move to? To upper respiratory<br /><br>tract or to intestines? (*4*1/CCR10/CD62L for upper respiratory tract) (*4*7/<br /><br>CCR9 for intestines).<br /><br>o PBMC*s (peripheral blood mononuclear cells): stimulate with LPS and measure<br /><br>IL-1, TNF, IL-6, IL-10 and IL-12<br /><br>o PBMC*s (peripheral blood mononuclear cells): stimulate with Tetanus Toxoid<br /><br>(TT)<br /><br>o PBMC*s (peripheral blood mononuclear cells): stimulate with conA (lectine) as<br /><br>positive control<br /><br>o PBMC*s (peripheral blood mononuclear cells): stimulate with Pokeweed as<br /><br>postive control for B-cells.<br /><br>o PBMC*s (peripheral blood mononuclear cells): Estimate proliferation by adding<br /><br>K167. </p><br>
Secondary Outcome Measures
NameTimeMethod
<p>- Faeces sample: intestine immunity (with Calprotectin test)<br /><br>- Saliva sample: IgA and TNF-alpha (with ELISA test)<br /><br>- Urine sample: Ketone bodies with Ketostix<br /><br>- Blood sample: stress hormones, glucose, free fatty acids, ketone bodies.<br /><br><br /><br>Tertiary:<br /><br>Blood: lactate, insulin, GI permeability markers<br /><br>Body composition: weight, length, fat percentage, bone and muscle weight (DEXA)<br /><br>Diet: food questionnaire app<br /><br>Physical activity: Physical activity level-questionnaire<br /><br>Questionnaires: delayed onset muscle soreness (DOMS), upper respiratory tract<br /><br>infection (URTI) questionnaire. Motivational Q and questionnaire on sleep,<br /><br>mental physical and emotional wellbeing<br /><br>Performance: RER (ratio CO2:O2) during exercise test. </p><br>
