Fat reduction without changing muscle mass of women as a result of exercising with weights

Abstract

Introduction/Aim - Morphological characteristics of women are biologically conditioned, but they are also liable to influences of environment, lifestyle, social status, type of job, etc. Apart from these factors, there is another strong one which influences the morphological space of women and that is physical activity. The aim of this research was to establish whether the individuals will manage to lose the surplus of fat tissue and, at the same time, keep the muscle mass on the same level, and all that after three months of experimental treatment which included exercising with weights. Methods - The research included 120 individuals, aged 20 to 24. The following items were measured: body height, body mass, skin folds and sizes. Fat tissue and muscle mass values were calculated by means of measured values of skin folds, size, body mass and height, and incorporated into a mathematical formula. The method of exercising which was used for this purpose was exercising with weights and stimulators. The results indicated that the value of F - test was proved to be statistically significant for the variable of the percent of fat tissue (%F), whereas for the variable of percent of muscle mass (%M) the difference was not statistically significant and it was on the level of 0.05. Conclusion - We can conclude that this kind of model of programmed body exercising of women brought to satisfactory results, in a sense of proportional reduction of fat tissue and total body mass, without increasing the muscle mass.
