ABSTRACT
Introduction: Stature is an important tool for identification and unique data of human being. Estimation of stature from bones is important for forensic as well as anthropological studies. It is necessary to derive the regression equations from the fragments of femur for medico legal situations. Thus from lower end of femur, estimation of total femoral length can be calculated and then this can be used to get stature by deriving statural formulae. In this study, regression equation for the estimation of total femoral length from epicondylar breadth of femur was computed. Subjects and Methods: Total 208 normal dry human femur bones which were preserved in antomy department of different medical colleges of Gujarat were studied. Total Femoral Length and Epicondylar Breadth of the Femur bone were measured for this study. Results: Epicondylar Breadth of femur displayed the higher correlation (0.828) with Total Femoral Length (TFL) for an individual measurement. As per regression analysis, regression equation is derived which is, B=338.004 + A * 1.390, Where A=Epicondylar Breadth of femur, and B= Total Femoral Length. Then the stature can be estimated by this total Femoral Length by the regression equations or the multiplication factors which are already established by various studies. Conclusion: The total Femoral Length can be estimated from fragmentary lower end of the femur. The total femoral length can be estimated by the equation presented in this study even in the absence of intact femur bone, and by which the stature can be estimated in sex and population sample.
ABSTRACT
Background: Athletes are trained for specific games and for specific muscle groups. In all the games respiratory muscles with proper strength are needed so as to provide better outcome. But as the peripheral muscles are trained the Respiratory muscles are not trained specifically in any of the athlete. The less trained Respiratory muscles can directly affect the output of the Athlete by activating Metaboreflex. This reflex is activated when the Respiratory muscles gets fatigued; in which the blood is pulled towards the fatigued Respiratory muscles; due to which the peripheral muscle gets less blood and oxygen to work longer; which results in reduced output. So as to improve overall output, along with specific muscles, the Respiratory muscles should also be trained. Aim: This study was designed to evaluate the effect of Inspiratory Muscle Trainer on Running Performance and Respiratory Muscle strength in Athletes. Materials and methods: An Interventional study was conducted on Athletes studying in a Physical Education college Gujarat. The subjects were selected according to inclusion criteria. The Pre-training outcome of PImax (Inspiratory Mouth Pressure); PEmax (Expiratory Mouth Pressure) and time taken for 30m sprint was taken. And then subjects were divided into two groups’ one training and other control. Group A: Training for Respiratory muscles by Inspiratory Muscle Training Device along with other regular physical activity. Group B: Not getting any additional training for Respiratory muscle other than regular physical activity. The training was given at 50% PImax for 15 min a day for 6 weeks. At the end of 6 weeks postdata of PImax PEmax and speed were collected. Agnihotri DS, Bhise AR, Patel SM. Effect of Inspiratory Muscle Trainer on Running Performance and Respiratory Muscle Strength in Athletes. IAIM, 2016; 3(8): 159-163. Page 160 Results: Data analysis was done using SPSS20 version. In Experimental group Inspiratory Mouth Pressure, Expiratory Mouth Pressure improved significantly (p<0.05) also time taken for completion of 30msprint reduced significantly. (p<0.05) Conclusion: The Inspiratory Muscle Trainer can be used to improve Inspiratory Mouth Pressure, Expiratory Mouth Pressure and Running Performance in Athletes.
