University volleyball athlete’s saliva’s pH variations subjected to test in a treadmill with increase of load

Abstract

There are several ways of physical and morphological assessments. The saliva has been studied for their reaction in exercises both in quantity and in its substrates. Among components that we can study in saliva, when we are practicing exercise, we have the pHs level. Therefore this present study aims to verify if exist any variation in saliva’s pH in women's volleyball athletes subject to testing in a treadmill with increasing load. The study included nine women with mean age of approximately 19 years, with average weight of 68kg and 1,711m in height. The same women practice volleyball for approximately 10 years and today are female athletes of the volleyball ́s team at the University Lutheran of Brazil (ULBRA), campus Canoas / RS. The tests were performed in LAFIMED in the afternoon and is divided into five stages. In each stage of two minutes was an increased load of effort and the saliva was collected in the spit way in a plastic cup. Subsequently the pH was analyzed for each stage. Obtained the following average results of the group studied pH: 7.61, 7.75, 7.69, 7.64 and 7.78 in five stages. The research showed that there is a pH ́s variation of saliva when subjected to the test with increasing load, but the variation was not equal in all individuals analyzed.
