Abstract. Title of the paper: Relationship between body composition measured by dual energy x-ray absorptiometry and reproduction performance in gilts This study was conducted to evaluate the relationship between body composition and reproduction traits in gilts. A number of 176 gilts of different genotypes were categorized in three different groups. Group 0 consists of gilts that were disqualified for breeding according performance test results or showed no occurrence of oestrus. Group 1 consists of all gilts, which farrowed after an artificially insemination. Group 2 was composed of gilts that were artificially inseminated but did not give birth to a litter. Body composition was determined in vivo using dual energy x-ray absorptiometry at a live weight of about 90 kg. Initial reproduction data from group 1 were also evaluated. Results of the performance test showed considerable variation among the different groups. Group 1 was significantly heavier and the daily gain was significantly higher than in group 0. However, results of breeding index and value were clearly below the results of the other two groups. The body fat content was significantly higher in gilts with a litter (>1.65 absolutely) than in gilts without a litter (group 2) and in disqualified gilts (group 0). Group 2 gilts showed the smallest body fat mass. However, the relation between DXA fat percentage and litter size for group 1 showed in tendency that the litter size might decrease with an increasing fat content of gilts. Therefore, an optimum body fat content for conventional breeding gilts of European or American origin needs to be determined for a maximum fertility.

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.

Whole-body electromyostimulation (WB-EMS), an innovative training technology, is considered as a joint-friendly, highly customizable and particularly time-effective option for improving muscle strength and stability, body composition and pain relief. The aim of the present study was to determine the effect of 16 weeks of once-weekly WB-EMS on maximum isometric trunk (MITS), leg extensor strength (MILES), lean body mass (LBM) and body-fat content. A cohort of 54 male amateur golfers, 18 to 70 years old and largely representative for healthy adults, were randomly assigned to a WB-EMS (n = 27) or a control group (CG: n = 27). Bipolar low-frequency WB-EMS combined with low-intensity movements was conducted once per week for 20 min at the participants’ locations, while the CG maintained their habitual activity. The intention to treat analysis with multiple imputation was applied. After 16 weeks of once-weekly WB-EMS application with an attendance rate close to 100%, we observed significant WB-EMS effects on MITS (p < 0.001), MILES (p = 0.001), LBM (p = 0.034), but not body-fat content (p = 0.080) and low-back pain (LBP: p ≥ 0.078). In summary, the commercial setting of once-weekly WB-EMS application is effective to enhance stability, maximum strength, body composition and, to a lower extent, LBP in amateur golfers widely representative for a healthy male cohort.
