Abstract. Title of the paper: Effect of selection on body fat content by means of the TOBEC method on some reproductive traits of rabbit does and on the body composition of growing rabbits In this experiment body fat content of Pannon White growing rabbits was determined at 10 weeks of age using an EM-SCAN SA-3152 type Small Animal Body Composition Analyser (TOBEC method). Based on the fat content determined the best and worst 16% of the does and the best and worst 8% of the bucks were chosen and mated with each other (fatty doe with fatty buck and lean doe with lean buck). It was found that the conception rate was significantly higher and the number of inseminations needed for the second kindling significantly lower in the case of fatty rabbits. An important, but not significant difference was observed in the case of total litter size at birth, which decreased in the case of live born litter size. This reason was the significantly higher ratio of the dead born pups in the case of non-fatty rabbits. Due to the higher ratio of total litter loss and suckling mortality in the case of fatty rabbits the litter size at 21 days differed notably, but again not significantly. In the offsprings of the F1 generation it was found that the fat content estimated and also the ratio of scapular and abdominal fat to the live weight calculated differed significantly (P < 0.05) from each other in the two experimental groups. The estimated fat content was 42% higher in the offsprings of fatty than in the offsprings of non-fatty rabbits. The differences in the ratio of the scapular and abdominal fat content to the live weight were 26% and 51%, respectively.

Body Fat Content

Body fat content and the melting point and fatty acid composition of body fat of hamsters exposed to 35, 27, 20, 15, 10, and 6 C for 2 weeks were determined. The relationship between exposure temperature and body fat content and composition resembled that between environmental temperature and metabolic rate. Below the critical temperature, there was a progressive decrease in total body fat content and melting point accompanied by a decrease in the mole fraction of palmitic acid and an increase in the mole fraction of oleic acid. The softening of body fat in cold-exposed animals appears to be the result of an increased mobilization of depot fat in response to a higher metabolic rate in the cold, a mobilization which is at least partially selective with respect to individual fatty acids or triglycerides. Examination of changes in whole body composition revealed that 72% of the loss in body weight of hamsters exposed to 6 C was due to a decrease in body fat content. In contrast, the decrease in body fat content accounted for only 28% of the body weight loss of pair-fed hamsters kept at 27 C on reduced caloric intake to match the body weight loss experienced by cold-exposed animals. It appears, therefore, that cold exposure induces a more effective fat depot mobilization than does reduced caloric intake. heat exposure; cold exposure; body composition Submitted on February 3, 1964

Childhood overweight and obesity, a worldwide problem, is generally identified using BMI (body mass index). However, this application of BMI has been little investigated in children below 5 years of age due to a lack of appropriate methods to assess body composition. Therefore, we used air displacement plethysmography (ADP) to study 4.4-year old boys and girls since this method is accurate in young children if they accept the requirements of the measurement. The purpose was to analyze the relationship between BMI and body fat in these children. Body composition was assessed in 76 (43 boys, 33 girls) of the 84 children brought to the measurement session. Boys and girls contained25.2±4.7and26.8±4.0% body fat, respectively. BMI-based cut-offs for overweight could not effectively identify children with a high body fat content. There was a significant (P<0.001) but weak (r=0.39) correlation between BMI and body fat (%). In conclusion, requirements associated with a successful assessment of body composition by means of ADP were accepted by most 4-year-olds. Furthermore, BMI-based cut-offs for overweight did not effectively identify children with a high body fatness and BMI explained only a small proportion of the variation in body fat (%) in this age group.

Abstract The main objective of this study was to evaluate the impact of milk intake, milk composition, and nutrient intake on piglet growth in lactation and body composition at weaning. To evaluate the body composition of piglets, data from one experiment (44 Danish Landrace × Yorkshire × Duroc piglets) were used to develop prediction equations for body pools of fat, protein, ash, and water based on live weight and deuterium dilution space (exp. 1). Furthermore, a total of 294 piglets (Danish Landrace × Yorkshire × Duroc) from 21 sows of second parity were included in a second experiment (exp. 2). In exp. 2, piglet live weight was recorded on days 3, 10, 17, and 25 of lactation. On the same days, the milk intake and body composition were measured, using the deuterium oxide (D2O) dilution technique. Piglet weight gain was highly positively correlated with the intake of milk and the intake of milk constituents each week and on an overall basis having r values ranging from 0.65 to 0.93 (P &lt; 0.001). When evaluating regressions for piglet growth, the milk intake in combination with the milk protein concentration explained 85% and 87% of the total variation in piglet gain in the second and third week of lactation, respectively, whereas milk intake was the only predictor of piglet gain in the first week of lactation explaining 81% of the variation. Fat, protein, and energy retention rates were all highly positively correlated with the daily intake of milk and intake of milk nutrients with r values ranging from 0.76 to 0.94 (P &lt; 0.001). Piglet gain and retention rates were rather weakly correlated with the milk composition with r values ranging from 0.01 to 0.50 (being either negative or positive). Curvilinear response curves were fitted for live weight gain and body fat content at weaning in response to milk protein concentration, showing that live weight gain was slightly greater and body fat content was slightly lower at 4.9% milk protein, but it should be emphasized that the quadratic effects did not reach significance. Body fat content at weaning was positively related with the intake of milk (R2 = 0.44, P &lt; 0.001) and milk fat (R2 = 0.46, P &lt; 0.01). In conclusion, milk intake had a major impact on the piglet growth rate, and milk fat intake greatly influenced the body fat percentage at weaning, whereas milk composition per se only played a minor role for these traits.

Validated methods of determining murine body composition are required for studies of obesity in mice. Dual-energy X-ray absorptiometry (DEXA) provides a noninvasive approach to assess body fat and lean tissue contents. Similar to DEXA analyses in other species, body fat measurements in mice show acceptable precision but suffer from poor accuracy. Because fat and lean tissues each contain various components, these inaccuracies likely result from selection of inappropriate calibration standards. Analysis of solvents showed that the PIXImus2 DEXA gave results consistent with theoretical calculations. Male mice weighing 26-60 g and having body fat percentages ranging from 3 to 49% were analyzed by both PIXImus2 DEXA and chemical carcass analysis. DEXA overestimated mouse fat content by an average of 3.3 g, and algorithms were generated to calculate body fat from both measured body fat values and the measured ratio of high- to low-energy X-ray attenuations. With calibration to mouse body fat content measured by carcass analysis, the PIXImus2 DEXA gives accurate body composition values in mice.

AbstractThe purpose of the present study was to identify the effects of a strength training program combined with specific plyometric exercises on body composition, vertical jump (VJ) height and strength development of lower limbs in elite male handball players. A 12-week program with combined strength and specific plyometric exercises was carried out for 7 weeks. Twelve elite male handball players (age: 21.6 ± 1.73) competing in the Portuguese Major League participated in the study. Besides the anthropometric measurements, several standardized jump tests were applied to assess VJ performance together with the strength development of the lower limbs in an isokinetic setting. No significant changes were found in body circumferences and diameters. Body fat content and fat mass decreased by 16.4 and 15.7% respectively, while lean body mass increased by 2.1%. Despite small significance, there was in fact an increase in squat jump (SJ), counter movement jump (CMJ) and 40 consecutive jumps after the training period (6.1, 3.8 and 6.8%, respectively). After the applied protocol, peak torque increased in lower limb extension and flexion in the majority of the movements assessed at 90°s-1. Consequently, it is possible to conclude that combining general strength-training with plyometric exercises can not only increase lower limb strength and improve VJ performance but also reduce body fat content.

The Impact

SummaryStudy aim: Over the last two decades, the body fat mass has been increasing and the level of physical fitness has been decreasing in school-aged children. Due to the health-related concerns that have arisen regarding school-aged children, the Hungarian government introduced everyday physical education in 2012. Since girls are more disposed to higher body fat and low fitness levels, the aim of our study was to characterise the physique, body composition and aerobic capacity of 10 to 14-year-old girls three years after the introduction of the new curriculum with daily PE lessons. Material and methods: All of the primary schools that were selected to participate in this study serve as partnership schools in the University of West Hungary’s teacher training programme (N = 8). The sample included only those upper primary school girls (10 to 14 years of age) who participated in the everyday physical education lesson (N = 543). Standard anthropometric techniques and a 20m shuttle run test were selected for the analysis. Results: An important result of this study was the finding that differences in the body composition features were consistently significant among the age groups. However, there were no differences among the age groups in the results of the 20 m multi-stage fitness test, nor in the girls’ relative aerobic capacity. Conclusions: It can be presumed that an unfavourable body composition and poor fitness occur primarily in the prepuberty years. Everyday physical education serves as a good opportunity for shaping the girls’ fitness level and body composition, and also for encouraging healthy active living.

The Impact

Abstract Introduction. The aim of the study was to assess the impact of 10 weeks of bodyweight training on selected elements of body composition (body mass, muscle mass, and the percentage of body fat and water) and components of physical fitness (strength, strength endurance, flexibility, and aerobic capacity) of women aged 21-23 years who do not practise sports professionally. Material and methods. The study involved 15 women whose mean age was 22 years 2 months. Their body mass and composition were assessed using a TANITA BC-1000 scale, and the following parameters of physical fitness were measured: the strength and power of the upper and lower extremities; the strength endurance of the shoulders, shoulder girdle, and trunk; as well as their flexibility and physical capacity. The assessment was performed twice, that is before and after the completion of the 10-week programme. Results. The study revealed that the 10-week bodyweight training programme had caused a minor increase in body mass (1.16%) and body fat percentage (2.43%), while muscle mass and body water percentage had not changed. As far as physical fitness is concerned, the bodyweight exercises had had a positive impact on all of the elements of physical fitness which were measured, including statistically significant increases in the explosive strength of the lower extremities (5.6%; p<0.01), strength endurance of the trunk (10.7%; p<0.01), and aerobic capacity (33.3%; p<0.05). Conclusions. Without a properly balanced diet and nutrition control, the bodyweight training programme had a small impact on the parameters of body composition. It was, however, an effective way of enhancing general physical fitness: apart from improving muscle strength and endurance, it also increased physical capacity and flexibility.
