The introduction established that the relationship that exists between BMI and other variables attributable to body composition are based on physiologic, pathologic and environmental factors. Due to this, data were collected on some of these key physiologic, pathologic and environmental factors in relation to the BMI of the subjects with normal weight. The average BMI of subjects with normal weight was found to be 22.03. This was in correspondence with an average age of 20.36 years. One physiologic feature of the data collection was the waist to hip ratio, of which an average 0.84 units were recorded among. Yet, the percentage of body fat recorded for the subjects with normal BMI was found to be 30.88. As part of the research question for the primary outcome, the researcher wanted to find out if the percentage of body fat in subjects with normal body mass index affects their six minute walk distance. In light of this, a predicted 6MWD of 433.67 was set for them, out of which an actual 6MWD of 430.60 was covered.

Body language

.... For this reason, the two psychologists focused on justifiable, subjective, and quantifiable experiences as the basis of behaviorism form of learning and teaching. B.F Skinner argued specifically that it is not easy to quantify the activities of the mind and therefore only observable indicators such as stimulus and responses should be used as a basis for behaviorism (Skinner, 1969). Skinner further suggested that facts about mental states could be reduced especially with regard to behavioral dispositions. Behaviorism school of thought believes that behaviors can be described in a scientific manner without referring to either internal psychological events or hypothetical dispositions such as beliefs. Ivan Pavlov played a major role...

Assignment: Anthropometry and Body Composition

...Anthropometry and Body Composition Anthropometric measurements are important constructs to assess nutritional status. Among the available constructs body mass index (BMI), body fat (%) and total fat mass are considered. These variables are defined using height, weight and circumferences of various parts of the body, such as waist, hip, neck and mid-upper arm. To develop a universally applicable construct, several proxy variables for height are considered in the literature. A gender-specific validation study is performed and it is seen that none of them are performing well in predicting height, especially for females. There is significant difference between the heights actually measured and heights predicted from the proxy variables...

Body Mass Index

...Body Mass Index The aim of this essay is to evaluate the subject of obesity, one of America’s health problems. BMI is used to determine an individual’s height and weight, and whether an individual is obese. Determination of Body Mass Index is established through the formula, 703*W/h^2, where W is the heaviness in pounds and h is the stature in inches (Ferrera, 2005). Angelina Jolie, a movie star, was chosen for this research. Her latest weight has been averaged to 127.5 (Zimbio, 2012). Using the formula BMI=703*w/h2, the maximum figure of BMI was used to find the height in each of the categories of weight status. In the underweight category, in which BMI is 18.5; the height is 69.6 inches. This is established as shown below: 18.5=703...

Body Mass Index

...Body Mass Index The body mass index (BMI) is a measure that is used to calculate an individual’s physique based on their height and weight in kilograms or pounds. BMI is calculated by dividing the mass of an individual by the square of their height, and it is denoted by a standard unit of Kg/. BMI is used to determine the suitability of person’s weight to their height. In healthcare, BMI is used to determine a person’s health status with relation to their general health. BMI values range from 18.5 to 25 for a healthy individual, and those that fall below 18.5 are deemed underweight while that above 25 indicates an overweight person. A BMI value that is above 30 suggests that a person is obese (Brownell & Puhl, 2005). Obesity has been...

Body Mass Index

...Body Mass Index BMI or body mass index is a measure of the human’s body in relation to body height and mass. This conceptwas devised between the 1830s and 1850s by a Belgian polymath called Adolphe Quatelet. Body mass index calculation is arrived by calculating the square of a body mass divided by the square height. To date it is the best proxy of body fat percentage in relation to height and weight. Body fat calculations and measures became paramount due to rising cases of obesity in western countries and enabled professionals to identify and address weight problems both overweight and underweight (Hoeger & Hoeger, 2012). Although it is mainly used for medical diagnosis, it was primarily not intended for that but for classifying sedentary...

Body Art

... ‘Body Art’ The carnival I visited exhibited human-art in the form of tattoos. The walking form of art was most surprising and commendable. Historically, tattoos on human body parts have been a tradition in many societies, but in some; they have never been appreciated either displayed vividly or kept hidden. The art engraved on diverse body parts display how a person wants to decorate, announce, remember, depict, denounce, his intended and unsaid message to others. Many at times, these tattoos are engraved at places where one wants to display it to the people he cares and often they are engraved at places where the world can see to decide their unsaid notions. The main idea here is announce the kind of message one cannot and does want...

Nutrition and Body Composition

Whole body composition comprises both fat-free body mass (FFM) and total body fat. The former is inclusive of water, bone matter and muscle and the latter pertains to essential fat and storage (stored) fat. Accordingly, Heyward and Stolarczyk (1996) assert that whole-body composition is of interest in terms of sports and exercise, obesity assessment and control of body weight. Of specific importance is the need to consistently ensure that total body fat is maintained at an optimal level (Heyward & Stolarczyk, 1996:4). The total body fat element is critical to optimal human physiological capacity. Thus, too little fatness, as is witnessed in individuals with eating disorders and exercise addiction as well as those with certain dise...

The State and the Impact That Homelessness Has on Children in Miami-Dade

Miami-Dade County has the highest homeless rate in the State of Florida. It ranks first in ‘families living in poverty’ among 25 major US cities (JLM, n.d.). Poverty and high rate of rentals have been considered the two main causes of homelessness. As much as 83% of people experience homelessness for a short period and usually require assistance in finding housing or rent subsidy. About 17% of the people in Miami-Dade are homeless for longer periods and require permanent supportive housing.

The impact of Plant Disease on New Zealand

Transmission of PMTV occurs through inoculation of sap in 26 species belonging to Solanaceae or Chenopodiaceae and to Tetragonia expansa and also through grafting (A. Reavy., W. Kashiwazaki., & Barker,1995 ). In some cases, PMTV is known to be transmitted by mechanical inoculation also.

Since PMTV is vectored only through S.subterranea the infection of plants with PMTV depends on the life cycle of S.subterranea which takes about 10-14 days. The life cycle of S.subterranean takes place in 2 phases: Phase I) This is the primary stage of the life cycle initiated with the germination of resting spores known as sporangiosori or cystosori persisting in the soil as spore balls with thick cell walls into zoosporangia.

The Role of Mass Media in the Development of Aggression

Despite the fact that longitudinal studies have proven that human aggression is to some extent an unwavering trait, it is undeniable that the environment plays a big role in influence the aforementioned behavior (Slaby & Roedell, 1982). Our daily encounter with the environment is a form of socialization that is defined as the process of integrating within oneself a sense of connection to a larger social world by means of discovering, understanding and adopting the beliefs, values, and norms of culture of other people. To a certain extent, sociologists consider the mass media as a powerful socializing agent as its significance is not constrained to the content alone of the media messages. Instead, it affects how we learn a...

A complete loss of articular cartilage is noted resulting in soft, elasticity loss, and fibrillation of the articular cartilage leading to the burned bone that is devoid of cartilage (Schwartz et al. 1942; LeadingMD par. 2).

Knee arthritis, that typically influences patients over 50 years old, affects all knee cartilage leading to biomechanical and biochemical changes that impairs cartilage function (LeadingMD par. 6).
