Participants also completed a comprehensive physical assessment and filled out self-reported measures using standard questionnaires and surveys. Comprehensive physical assessment The physical measures were assessed per the protocols described below in the following order: All measures were collected by trained data collection staff. The participant was asked to slowly reach with her arms extended as far as she could while her legs were extended and her feet were flat against the box.
Three trials were conducted, with the best of three recorded. Participants started with their back and knees flexed, feet on the floor, heels 30—46 cm from the buttocks, and arms crossed over the chest with hands on opposite shoulders. The test was stopped when the participant rested or when the push-up form was compromised.
While standing, with the arm to be tested extended by her side, the participant was asked to grip as hard as possible for a few seconds. The highest combined total was used as her grip strength score, measured to the nearest kilogram. Questionnaires Self-report questionnaires were used to assess PA, eating habits, and health behaviors. When data were not available at baseline for a participant, the mean score at baseline of all participants for that particular measure was entered, consistent with the intent-to-treat approach that was utilized in the parent studies.
Keeping your calories, protein and fiber in check is a good place to start if you want to improve your body composition and health. Physical Activity and Exercise Physical activity and exercise are other crucial components for improving body composition. They not only increase the calories you use, but they are also necessary for optimal muscle growth. Since body composition can be improved by decreasing fat mass or increasing muscle mass, this is an important point.
Your muscles need to be challenged by exercise, particularly weight training, to grow and get stronger However, many types of exercise can potentially help with fat loss The American College of Sports Medicine states that — minutes of exercise per week may lead to a small amount of weight loss If you exercise 5 days per week, this comes out to 30—50 minutes per day, though they recommend minutes per week or more to promote significant weight loss While these recommendations focus on body weight, it is important to remember that some forms of exercise will build muscle while you are losing fat.
This is another example of why thinking about your body composition, rather than just body weight, is a good idea. Other Factors Additional factors beyond nutrition and exercise may affect body composition. There is some evidence that people who have poorer sleep quality have worse body composition than those with good sleep quality Regardless, it is a good idea to consider whether your sleep habits can be improved.

Alcohol consumption is another factor that may affect body composition. Since alcohol contains calories, it can contribute to excess calorie intake and fat gain Some research has also shown that individuals who consume a lot of alcohol are more likely to be obese Additionally, some factors that affect body composition cannot be changed. For example, both age and genetics impact body composition. However, since you cannot control these factors, it is probably best to focus on what you can control, like nutrition, exercise and sleep.
Nutrition and exercise are critical for improving body composition.

Keeping your calories, fiber and protein in check is a good first step. All exercise can help with fat loss, but weight training is the best way to increase muscle mass.
The Bottom Line Stepping on the scale will only tell you how much you weigh. You can get a more accurate picture by taking into account your body composition, or your fat mass and muscle mass.
Two simple ways to track your body composition over time include measuring the circumference of different body parts and taking progress pictures at regular intervals. There are also devices you can buy to track your body composition, but many are inaccurate.
The gender differences in physical fitness performance can be explained in part by gender difference in body composition.
It is been reported that boys have greater muscle mass, bone density and less body fat than girls across age groups [ 1719303449 ]. Previous research studies indicated that excessive fatness have a negative impact on the performance tasks in which the body is projected through space, as in standing broad jump, and on tasks in which the body must be lifted in space, as in bent arm hang [ 30 - 3238 ].
Additionally, both the underweight boys and girls were able to hang more seconds in bent arm hang than the overweight group. A study by Artero et al. No significant differences were found in sit-ups in the normal, underweight and obese groups in girls. Comparatively, the physical fitness performances of adolescents in this study were poorer than that of the AVENA study [ 34 ] and the Republic of Seychelles study [ 27 ].
The results showed strong ORs for the relationship between physical fitness and body composition for moderately fit overweight girls. The observed relationship may be explained by many factors, among others high level of physical fitness which may be attributed to household chores and walking distance to and from school [ 37 ], but unfortunately such information was not assessed in this study.
The results show that children with high physical fitness have lower odds for being overweight than children with low physical fitness, and these findings are consistent with other studies. For example, research findings by Shang et al. Comparable findings from a cross-sectional study in adolescents from the Republic of Seychelles by Bovet et al. In the present study overweight girls with low physical fitness performed worse in physical fitness than the boys and as such these differences may be explained by the fact that the development of BMI for girls is reported to be greater than that of boys from 12 years to Since the development is greater it might also have more effect on the capability to perform physical fitness which may explain the stronger association found in girls [ 194950 ].
From the epidemiological perspectives it is being reported that over-nutrition, which is associated with inadequate physical activity, is assumed to be the product of several risk factors during adolescence [ 242629 ], hence the need for strategic intervention. It should be realized that the current study has some limitations which requires caution in the interpretation of the data. It should be noted that physical fitness is a function of both physical activity and non-modifiable factors such as genetics [ 1931 ], and these factors were however not assessed in the present study and therefore, it was impossible to assess their relative contribution.
This study was based on cross-sectional data baseline measurements of the PAHLS study, which is set up to be a five year longitudinal study on a group of 14 year-olds who will be followed up until they reach 18 years of age. Available data on measures of strength rather than cardiovascular health is a limitation of the study, which in future studies will be incorporated.
In addition, the categorization of adolescents by their BMI may have had an effect on sample size, which as such may have contributed to observed large confidence intervals. Nevertheless, this cross-sectional study will contribute important information about the population of Tlokwe Local Municipality to the body of science.
Another limitation of this study might be that the performed analyses are only adjusted for locality of the schools and race. Maturation may one way or the other have affected the results notwithstanding that the study subjects are drawn from a homogeneous age group; unfortunately no reliable data on maturation could be collected within the present study.
Conclusion Our baseline study of 14 year-old high school adolescents residing within the Tlokwe Local Municipality indicates the coexistence of both underweight and overweight. In addition, the results show a strong association between physical fitness and body composition especially in the overweight girls on the one hand, while on the other hand the underweight performed better than the normal weight, and than the overweight.
The results show the same trend for boys, but not as strong. The girls were therefore more affected than the boys. As such, from public health perspectives in a country like South Africa with a double paradox of weight status, intervention programs with the objective of low fat mass for overweight and fat-free mass muscular fitness for underweight adolescents should be the start of the beginning, hence well-structured physical fitness program for all.
