SALIVARY CORTISOL DECREASES WITH A PRE- AND POST-RESISTANCE EXERCISE CARBOHYDRATE/PROTEIN SUPPLEMENT IN UNTRAINED SUBJECTS

Title:	SALIVARY CORTISOL DECREASES WITH A PRE- AND POST-RESISTANCE EXERCISE CARBOHYDRATE/PROTEIN SUPPLEMENT IN UNTRAINED SUBJECTS
Author:	Dominguez, James M, II
Description:	Salivary cortisol was measured in eight college-aged males (4 trained-TR; 4 currently not training-UT) during participation in each of 3 randomly assigned conditions: 1) SUP; pre- and post-exercise carbohydrate/protein (CHO/PRO) supplement; 2) PLA; pre- and post-exercise liquid placebo; 3) CON; consumed CHO/PRO supplement and participated in all testing procedures except resistance training. Training was intense and full-body, consisting of 3 sets of 10 repetitions from 8 exercises. The CHO/PRO supplement provided 1g/kg CHO and .6g/kg PRO (.32g/kg EAA). The beverages were consumed 30 minutes prior to, and immediately after exercise. Saliva was collected at six time periods relative to the exercise session (-30, -0, +0, +15, +30, +45). TR subjects displayed no increase in cortisol at any point across time or treatment. UT-PLA displayed a large increase in cortisol above UT-SUP and baseline at +15 and +30. These data indicate that in UT subjects, the post-resistance training cortisol response can be abolished with CHO/PRO supplementation.
