whether or not they receive support ( Goodwin, Costa, & Adonu, 2004 ). The primary models used to describe and explain how social support may influence both physical and mental health outcomes are the main effects model and the stress-buffering model ( Cohen & Wills, 1985 ). According to the main effects

( Vanhatalo et al., 2010 ). Beta-Alanine Beta-alanine is the rate-limiting precursor to carnosine, an endogenous intracellular (muscle) buffer, and one of the immediate defenses against the accumulation of protons in the contracting musculature during exercise ( Lancha Junior et al., 2015 ). Daily

November 2013 to October 2015, at which time, the desired baseline cohort size was achieved. Participants were 18 years and older and lived within the 3-mile Euclidean buffer around the light rail system at baseline. As such, the sample is not considered representative of a greater population. Only 1

volume indicator within the swab handle changed color to indicate when sufficient saliva volume had been collected. Then, the swab was removed from the mouth and placed into the OFC buffer. The duration of collection time was less than 60 seconds. The buffer contains extraction agents to draw the target
