INTRODUCTION
Saliva is a watery fluid, secreted into the mouth glands and it has various functions, few facilitate taste, to chew and swallow, to lubricate the mouth and initiate starch digestion. Workouts every system of the body, like blood flow, chemical levels with some effects, lasting others. Sometimes it can even result in chronic [1] It leads to various changes in the brain hormone and metabolite levels. Over a period volume and cardiac output increase. [2][3] Saliva hassle free and non-invasive, and can provide various physical and chemical parameters, potentially harmful consequences of other arterial or venous samples and tissue biopsies. [4] increased intensity of exercise, the salivary is increased, which leads to increased viscosity. The salivary secretion is controlled by sympathetic saliva with increased protein levels) and (watery clear saliva) innervation. [10,11] viscosity of saliva after exercise can be dehydration, increased concentration of proteins and due to evaporation of saliva owing breathing. [12]

MATERIALS AND METHODS
A study was performed among 30 healthy individuals, randomly, without any systemic complications.

The study was aimed at evaluating the effect of characteristics of saliva like salivary flow, pH and function on teeth. After an intense workout, there are various molecular and physical, which can be evaluated to composition and nature which may predispose to plaque healthy people, picked randomly, had an intense workout Saliva was collected before and after exercise, and tested salivary flow, pH and viscosity. The time for salivary flow the pH (t test) was decreased and the results were not viscosity of the saliva (chi square tests). mouth by salivary of which are to lubricate and moisten Workouts impact flow, metabolism and lasting longer than the chronic adaptations. brain altering the period of time blood Saliva collection is provide information on parameters, without the other samples like biopsies.

The saliva samples were collected before and after an intense recorded were saliva flow, viscosity

Flow
The time taken for the droplets salivary glands (lower labial) piece of gauze, was recorded with

Viscosity
The saliva was collected in a into one of the following groups: Watery clear, bubbly frothy and pH: The saliva in the collecting cup dipping a pH paper into it for visually recorded by comparing All the above parameters were collected before and after the individual. The data was analysed The tests used were paired sample and chi square tests. Statistical

RESULTS
The results of the study conducted

Flow
The average time for salivary 26.20s, after exercise. In the were highly significant (p=0.000) droplets of saliva to form in the minor l) after being blotted dry with a with a timer. collecting cup, and categorised groups: and sticky frothy (with deposits) cup was examined for the pH by 10s, and the colour change was comparing it with the pH chart.
were recorded in the samples the exercise session, by the same analysed using SPSS software. sample t-test (for pH and flow rate) Statistical significance is set at <0.05 conducted are as follows: salivary flow increased from 13.56s to paired sample t-test, the results p=0.000)

pH:
The average pH increased decreased from 6.88 the paired sample t test, the results were significant

Viscosity
The results from the pearson chi square significant (p=0.459), and the results from McNemar Test were slightly significant (p=0.035) 80% had sticky frothy saliva after exercise.   implies an increase in the viscosity of saliva after exercise. In a study by C.A. Horswill et al, the post exercise flow rate of saliva wasn't different on consumption of sports drinks, but increased with consumption of water. And depending on the beverage consumed after exercise, the pH varied (highest for water and lowest for home-made drinks like lemon juice) [14] In our study there has been a statistically significant increase in time for flow of saliva and decrease in pH observed after exercise. Since the sample size was limited, further studies with larger sample sizes may yield more accurate results.

CONCLUSION
Use of Saliva in laboratory analysis, has a great potential, though standardisation of certain variables like system of collection, analyte to be quantified and schedules for collection, direct volume quantification, sample recovery and prevention of contamination is required. [15] There are various physiological variations in the saliva as observed in the study. Normally, the physiological alterations are overlooked, and research has been thriving only in the pathology of diseases. But it has to be kept in mind that physiological alterations like these, and the fact that people tend to consume beverages like energy drinks and juices after exercise, that further reduce their salivary pH levels, which will have a profound impact on the time taken by the oral cavity to recover to its normal conditions. These variations may predispose to plaque accumulation and initiation of dental caries.
