Continuous inadequate food which caused low energy state of Ethiopian children.
The expectation was that the grip strength will improve with the improvement nutritional status. There was grip strength increase with weight of the children, with boys found to be stronger than girls under the same weight range in their right arm grip strength.Chatterjee, et al. showed that grip strength was positively correlated with weight which reveals (r=0.87 and r=0.88 left arms),and height (r=0.9 for both arms).
The relationship of strength to body size and the fact that boys have a slight size advantage over girls' aid in explaining the differences in grip strengths between the two sexes, also since body size is related with age then the increase in grip strength with age can be related to an increase in body size.
The significant outcome of grip strength on a three-year gap period can be explained using the velocity of growth in body size in different age groups.
Group strength comparison with weight and height in research study can aid in the assessment of physical maturity.Baccous et al. suggested the use of height and grip strength as a practical non-invasive method to classify physical maturity in boys.
The regression equation formulated for right arm grip strength vs. BMI can be useful in predicting strength from BMI measurements. The instrument advisable for use is hand dynamometer, it is a simple non-invasive instrument, more so, it is reliable and its concurrent validity is conformed with grip strengths relation to upper muscle cross sectional area and physical performance
CONCLUSION
With the use of hand dynamometer, grip strength measurement can be made use of for a wider physiological and clinical application. The research study revealed the normal mean values and the regression equation that can enable one to predict the right arm grip strength from BMI of children, this plays an important role since it assist physicians as well as basic science researchers in this area of specialization. The research study also aid in identifying the cause of the mean differences such as malnutrition, inadequate food which leads to struggle in identification of solutions to curb the differences.

This is especially true if, as has been suggested (Staudohar 2005), that despite stricter testing procedures, professional athletes still use anabolic steroids and human growth hormone in large numbers that greatly exceed those acknowledged or caught by their respective league governing bodies. By process of elimination, it would appear that the primary impetus for anti- steroid regulations in professional sports is public perception, and that favorable public relations and maintenance
athletic coach I have garnered a wide variety of skills, as well as an extensive understanding of the standard practices and procedures an individual in the field of exercise science should possess. My past experiences have provided me with substantial knowledge of the principles involved in the prevention and care of athletic injuries. With the following, I hope to illustrate that my experiences and subsequent research have provided me
Sociology of Sport: The Ideals of Sport as a Reflection of Society Sport has become a central part of society, introduced to children at a young age and often continuing to be part of a person's life throughout their lifetime. Sport impacts on people in a number of ways. In childhood, the focus of sport is often on participating, working with other people and aspiring to be the best you
Child Clinical Intervention Part I Child Abuse Physical abuse of children occurs throughout every social strata, although there may be an increased incidence among those living in poverty. Abuse often occurs at moments of great stress, and the perpetrator strikes out in anger at the child. The perpetrator may also have been abused as a child and may have poor impulse control. Because of the relative size and strength difference between adults
Sports Management The subject of sports is today not a method only for individuals to get enjoyment from it, but sports has become an important method for individuals also to maintain fitness and thus contribute to his being able to perform as per requirements of his main financial earnings source. At the same time, this has given rise to a group of individuals who are the leaders in the management of
It's well-known that soccer, like religion, can provoke violence like hooliganism and tramplings at overcrowded, large stadiums, and this is what many Americans assume it is all about. "But soccer has also proved unique in its ability to bridge differences and overturn national prejudices. The fact that the World Cup could even take place in South Korea and in Japan, as it did in 2002, was a victory for tolerance
