STUDY OF BREATH HOLDING TIME AND LUNG FUNCTION TEST

Abstract

Aim: To evaluate and compare the breath holding time and different lung function test in playing and sedentary group. Material and method: This study was performs on 50 healthy male individuals. The age range is 20-32 years. It is divided in playing group and sedentary group. Each group has 25 individuals and performs breath holding time (BHTT) after normal and without forceful in-spiration, deep inspiration (BDI) and hyperventilation (BHY) in chair sitting position at morning time. After completing BHT, performs lung function test i.e. FVC (Lit), FVC 0.5 (Lit.), FVC 1 (Lit.), FVC 3 (Lit.), PEFR (L/S), FEF 25-75 (L/S), FEF 2-12 (L/S), FEF 25%, FEF 50%, FEF 75% and MVV (L/Min) by computerized spirometry (MEDSPIROR). The data was analyzed by Graph pad in stat 3 versions by using unpaired student t test. Results: On statistical study BHTT, BDI and BHY are very significant. The lung functions FVC (Lit), FVC 1 (Lit.), FVC 3 (Lit.), PEFR (L/S), FEF 25-75 (L/S), FEF 2-12 (L/S), FEF 25%, FEF 50%, FEF 75% and MVV (L/Min) are statistically significant but FVC 0.5 (Lit.) is not significant in playing than the sedentary. Discussion: Improvement due to increase inhibitory stimuli, decrease airways resistance and oxygen consumptions in tissue. Improve the tone of smooth muscle and enhance the para-sympathetic activity. Conclusion: The breath holding time in normal inspiration, deep inspiration and hyperventi-lation is more in playing people than the sedentary people and same way lung function (ob-jective parameter) were also more in playing people.
