Introduction/Objective. Body fat percentage (BFP) is the most reliable indicator of a nutritional status. For clinical practice it is important but scarcely investigated whether to exclusively use contemporary methods of BFP measurement, or classic anthropometric methods are also reliable. The aim was to investigate the correlation between the results of BFP measuring using a contemporary method of bioimpedance (Bio) and classic methods of skin fold thickness (SFT) and body mass index (BMI). Method. There were 279 patients of the Dietetic Counseling Center of the Institute for Public Health in Nis who were included in the research during 2015. Body fat percentage was determined using three classic anthropometric methods of ST over the triceps, and the scapula and BMI. Apparatus OMRON BF 302 was used for BFP measuring with bioimpedance method. Results. Using a one factorial analysis of variance we found a statistically significant difference between the mean values of the BFP obtained with bioimpedance and with anthropometric methods (F = 24.19, p < 0.05). Post hoc analysis revealed a statistically significant difference between the BFP determined with bioimpedance and SFT over the triceps and the scapula, while the anthropometric method based on BMI gave the results similar to those from bioimpedance. Conclusion. We show that the most reliable anthropometric method of determination of BFP is that based on BMI, as its results correlate best with those obtained with a contemporary method of bioimpedance.

Objective: To compare the anthropometric characteristics of sedentary women beginners in a physical exercise program in the gym, which had clinical diagnosis of hypothyroidism, with women who did not have hypothyroidism. Methods: The sample consisted of eighty women aged between 23 and 45 years who started in a gym at an interval of two years and who had hypothyroidism and the control group, without this pathology, selected in a simple random way. Anthropometric measurements, such as body mass, height, body mass index, abdominal circumference and waist, and body fat percentage were performed. Student's t-test was applied for independent samples between groups and Pearson correlation within groups. The statistical significance adopted was p < 0.05. Results: The group with hypothyroidism showed significant difference (p = 0.05) compared to control group for the body fat percentage just for women above 35 years, just like women with hypothyroidism above 35 years showed strong association of anthropometric variables with waist hip ratio (r ≥ 0.70). Conclusion: Sedentary women, above 35 years and affected by hypothyroidism, showed greater association of anthropometric variables with the predisposition to the risk of developing cardiovascular disease compared to their peers without the condition, and below this age range.

Purpose: the purpose of this study was to verify if there is any significant difference between body fat assessment by calculating body mass index and by using bioelectrical impedance analysis. Materials: subsequently we determined the ratio between body fat and muscular mass percentage in a sample of 156 university girl students. Results: BMI and muscle mass percentage seem to have similar variance and trends, while body fat exceeded in numbers and percents the highest levels of BMI. While by calculating BMI the found number of overweight and obese subjects was 23 from the total of 156, (14 %); by measuring body fat percentage that number increased to 67 (43%) of girl students in the sample. The t test showed significant difference between BMI values and the body fat percentage for the study sample: t (155) = 2.37, p-0.01. Conclusions: this study supports the idea that BMI results may be insufficient for correct assessment of overweight and obesity risk. Body composition adds useful information about health and fitness. A few concluding recommendations, regarding beneficial effects of exercise, have been made aiming to provide students of all body parameters with meaningful, relevant and positive physical education and health knowledge.

Running is a popular form of physical activity and can be carried out through several different distances. Morphological characteristics, such as skin fold thickness, limb girth and length, body weight and body fat percentage have an impact on endurance running. The objective of this systematic review study is to collect and analyze studies about the influence of morphological characteristics on running performance of endurance athletes. Based on an analysis of electronic databases and the inclusion criteria set, 20 studies were included in the analysis. The length of the extremities and the sum of the skin folds thickness have the highest statistical significance as the predictor. The results of the analyzed studies indicate that slim limbs, longer legs, lower total skin fold thickness and lower body fat percentage are some of the characteristics that can be good predictors for competitive success and a model to be tended during the preparation period of male and female endurance runners.

BACKGROUND: The inability of athletes to train or the decrease in the intensity and frequency of training may cause athletes to lose performance. Particularly in view of the current COVID-19 pandemic, maintaining strength outside the normal framework provides an advantage to athletes for the next competitions. OBJECTIVE: To compare the CrossFit Barbara which can be applied easily at home during the off-season or some situations such as the epidemic limitation to classic resistance training methods used to maintain the strength performance of national kickboxers. METHODS: Forty-three national kickboxers, CrossFit (CF, n= 22), and resistance training (RT, n= 21), participated in this study. While CF performed 20 pull-ups, 30 push-ups, 40 sit-ups, and 50 squat exercises, RT performed bench press, lat pull down, leg press, biceps curl, and triceps extension exercises twice per week for six weeks. Before and after the six weeks, the following variables were measured; body mass (BM) and body fat percentage (FP), VO2max, bench press (BP), squat (SQ), leg strength (LS), hand grip strength (HGS), pull-up, push-up and counter movement jump (CMJ). RESULTS: BP (p< 0.001, F= 41.125, ηp2= 0.501), SQ (p< 0.001, F= 26.604, ηp2= 0.394), LS (p< 0.001, F= 15.234, ηp2= 0.271), push-up (p< 0.001, F= 31.978, ηp2= 0.438) and pull-up (p< 0.001, F= 24.410, ηp2= 0.373) values changed significantly in group-time interaction between CF and RT groups, while there was no significant difference for the BM (p= 0.198, F= 1.715, ηp2= 0.040), Fat (p= 0.265, F= 1.279, ηp2= 0.030), HGS (p= 0.665, F= 0.190, ηp2= 0.005, CMJ (p= 0.054, F= 3.946, ηp2= 0.088) and VO2max (p=0.747, F= 0.106, ηp2= 0.003). Furthermore, according to the before and after study values, BP, SQ, LS, and CMJ decreased significantly (p< 0.05) while BM, FP, HGS, VO2max, pull-up and push-up variables did not in the CF (p> 0.05). In the RT, the pull-up and push-up variables decreased significantly (p< 0.05) while there was no significant difference for BP, SQ, LS, HGS, VO2max, body mass, body fat percentage and CMJ (p> 0.05). CONCLUSION: CF Barbara workout was more effective in maintaining strength endurance performances, and RT in maintaining maximum strength performances. According to the individual performance needs of athletes, reasonable training method can be used to prevent performance decrement in the strength domain.

Background: High-intensity training is comprised of sprint interval training (SIT) and high-intensity interval training (HIIT). This study compared high-intensity training with moderate-intensity continuous training (MICT) on cardiorespiratory fitness (CRF) and body fat percentage for overweight or obese persons. Methods: A systematic search of randomized controlled trials using the health science databases occurred up to April, 2020. Twenty-six studies were included for complete analysis. A total of 784 participations were analyzed. The unstandardized mean difference for each outcome measurement was extracted from the studies and pooled with the random effects model. Results: MICT was significantly better at improving CRF compared with SIT (mean difference = −0.92; 95% confidence interval, −1.63 to −0.21; P = .01; I2 = 10%). Furthermore, there was no significant difference between MICT versus HIIT on CRF (mean difference = −0.52; 95% confidence interval, −1.18 to 0.13; P = .12; I2 = 23%). There was no significant difference in body fat percentage between MICT versus HIIT and MICT versus SIT. Conclusions: MICT was significantly better at improving CRF than SIT in overweight or obese persons.

Background:Three-dimensional photonic scanning (3DPS) was recently developed to measuredimensions of a human body surface. Objective:The purpose of this study was to explore the validity of bodyvolume measured by 3DPS for estimating the percent body fat (%fat). Design, setting, participants, andmeasurement:The body volumes were determined by 3DPS in 52 women. The body volume was corrected forresidual lung volume. The %fat was estimated from body density and compared with the corresponding referencevalue determined by the dual-energy x-ray absorptiometry (DXA). Results:No significant difference was foundfor the mean values of %fat obtained by 3DPS (22.2 ± 7.6%) and DXA (23.5 ± 4.9%). The root mean squareerror of %fat between 3DPS and reference technique was 6.0%. For each body segment, there was a significantpositive correlation between 3DPS- and DXA-values, although the corresponding value for the head was slightlylarger in 3DPS than in DXA. Residual lung volume was negatively correlated with the estimated error in %fat.Conclusions:The body volume determined with 3DPS is potentially useful for estimating %fat. A possiblestrategy for enhancing the measurement accuracy of %fat might be to refine the protocol for preparing thesubject’s hair prior to scanning and to improve the accuracy in the measurement of residual lung volume.
