Introduction: Powerlifting has three disciplines includes, squat, bench press, and dead lifting. There may be heavy weights are lifted during training and competitions (1). In the competitions the powerlifter has to lift each technique 3 times and highest weight was considered. It is calculated as four times more than own body weight. During training, muscle strength increased by submaximal loads, and in a previous study, powerlifters exercised, on average, 6.1 ± 2.4 h/week (2). During the powerlifting techniques the cardiac output gets increased and it increases heart rate within the magnitude of the increase dependent upon the intensity of the exercises (9). During physical exertion there is an increase in cardiac output, a rise in systolic blood pressure is a natural consequence of dynamic exercises. Diastolic blood pressure remains unchanged or shows only a slight increase as a consequence of metabolic vasodilatation of the peripheral vessels (10).
Objectives: To determine the Heart Rate variation in obese person - pre and post powerlifting exercises. 1. To determine the systolic Blood Pressure changes in obese person - pre and post powerlifting exercises. 2. To determine the Diastolic Blood Pressure variation in obese person - pre and post powerlifting exercises.
Inclusion Criteria: Male participants with BMI more than 25.2.age group of 23—35 years.
Exclusion Criteria: 1.No prior history of any form of musculoskeletal disabilities, neurological or respiratory complains.2.Absence of high blood pressure or low blood pressure.3.No cardiac diseases.
Methodology and procedure: An experimental study was done with 50 obese individuals were selected after assessing their physical functions, Participants were recruited from the pool of 120 obese individuals who visit to the gymnasium for the recent time. Participants were given clear instructions about the study and those who accepts were involved in the selection process. The selection of the participants was based on the selection criteria. The age group of participants was 23—35 years, participants with BMI more than 25, male participants only involved, without any history of musculoskeletal problems, participants without any neurological or respiratory complains, participants without any history of high blood pressure or low blood pressure or any sort of cardiac diseases. Participants are instructed to stop from the study at any time. Written consent form was obtained from all the participants. A detailed explanation was presented to them through power point slides about the study. All the participants were involved in power lifting for 35 mins, which includes 5 mins of warming up, 5 mins of dead lifts, 5 mins for mini squats, 5 mins of bench press and 10 mins of power lifting based on the individual 10 Repetition maximum and 5 mins of cool down exercises. The study was for one week with 4 days of exercises. The data were collected on the day one of the patient and after exercises, and at the end of first week. The data were collected through pulse oximetry for heart rate and sphygmomanometer for diastolic and systolic blood pressure. The collected data was analysed through SPSS 21.0.
Results: The results have identified that there were significant differences shown within the exercises and between the exercises. Anova analysis of the p-value corresponding to the F-statistic of one-way ANOVA is lower than 0.05, suggesting that the one or more exercises are significantly different. On analysing with the post hoc test. The results of this study show both exercises were improved whereas there was a significant improvement noted on Pre-test, immediate post and 1 week after post. So, this study rejects null hypothesis.
Conclusions: This study concludes that there is a significant rise in the heart rate and blood pressure following exercises, but the elevation of these cardiac parameters will tend to reduce following regular exercises. Pages: 96-99 | 27 Views 8 DownloadsDownload Full Article:
