Flaxseed Flour

The aim of this study was analyzed if the flour or flaxseed oil treatment contributes to body composition in male rats subjected to early weaning. Pups were weaned for separation from mother at 14 (early weaning, EW) and 21 days (control, C). At 21 days, part of the pups was evaluated (C21 v. EW21). After 21 days, control (C60) was fed with control diet. EW was divided in control (EWC60); flaxseed flour (EWFF60); flaxseed oil (EWFO60) diets until 60 days. Body mass, length and body composition by dual-energy X-ray absorptiometry were determined. EW21 (v. C21) and EWC60 (v. C60 and EWFF60) showed lower (P<0.05) mass, length and body composition. EWFO60 (v. C60 and EWFF60) showed lower (P<0.05) body mass and length, body and trunk lean mass, bone mineral density and content and bone area. Flaxseed flour, in comparison with flaxseed oil, contributes to recovery of body composition after early weaning.

The precocious interruption of lactation is a prime factor for developmental plasticity. Here we analyzed whether flour or flaxseed oil treatment contributes to body and brain mass in male rats subjected to early weaning. Pups were weaned for separation from their mother at 14 (early weaning, EW) and 21 days (control, C). At 21 days, some of the pups were evaluated (C21 v. EW21). After 21 days, control pups (C60) were fed a control diet. EW pups were divided into those fed a control diet (EWC60), those given flaxseed flour (EWFF60), and those given flaxseed oil (EWFO60) until 60 days. EW21 showed lower body and absolute brain mass and higher relative brain mass. At 60 days, EWC60 and EWFO60 had lower body mass. With regard to relative brain mass, EWC60 was heavier; EWFO60 had lower values compared with EWC60 and higher values compared with C60 and EWFF60. These results indicated that flaxseed flour, in comparison with flaxseed oil, contributes to brain development after EW.

The present study was designed to evaluate intra-abdominal adiposity in rats subjected to early weaning and subsequently treated with diet containing flour or flaxseed oil until young life. Pups were weaned for separation from mothers at 14 days (early weaning, EW), and 21 days (control, C). After 21 days, control (C60) was fed with control diet. EW was divided into control (EWC60); flaxseed flour (EWFF60); flaxseed oil (EWFO60) diets until 60 days. At 21-60 day, intra-abdominal fat mass were evaluated. At 60 days, retroperitoneal adipocyte area was determined. At 21 days, EW group displayed lower (P<0.05) intra-abdominal fat mass. At 60 days, EWC60 group displayed lower (P<0.05) intra-abdominal fat mass. Adipocytes area were lower (P<0.05) in experimental groups. EWC60 displayed lower (P < 0.05) adipocytes area (vs. EWFF60 and EWFO60). Flour and flaxseed oil diets contribute to recovery of intra-abdominal adiposity after precocious interruption of lactation.

Abstract Introduction: The aim of the present study was to evaluate the influence of body composition on the postural sway during quiet standing. Our hypothesis is that men and women do not have the same relation between body composition and postural sway during quiet standing. Materials and Methods: Participated in the study 50 men and 50 women; age range: 20-40 years old. The main outcome measures were: Body composition (bone densitometry), percentage of fat (% fat) tissue (g), fat (g), lean mass (g), bone mineral content (g) and bone mineral density (g/cm2); Anthropometry: body mass (kg), height (cm), length of the trunk-head (cm), length of lower limbs (cm). The following indices were calculated: body mass index (BMI) (kg/m2) and Postural balance test - center ofpressure displacement. Results: The correlation analysis showed low correlations between postural sway and anthropometric variables. The multiple linear regression model showed that the body composition and the anthropometry were able to explain only men's postural sway. Conclusion: The postural sway is sex type dependent. Men and women have different relations between body composition and postural sway. Only male's body composition affected the body sway.

Background and objectives: Peritoneal dialysis (PD) patients are expected to present lower levels of physical activity, unhealthy changes at the body composition level, and low levels of strength. Firstly, this study aimed to report the sex differences in physical activity, body composition and muscle strength and the relations among these variables. Secondly, we analyze the relationship between physical activity and biochemical parameters. Materials and Methods: Thirty-four patients (13 women and 21 men) participated in this study. Body composition was assessed by bioimpedance and dual-energy X-ray absorptiometry (DXA), and maximum isokinetic unilateral strength, analytical parameters and physical activity levels were evaluated. Results: The men showed higher values for weight, height, lean body mass, bone mineral content, bone mineral density (BMD) and total body water, while women showed higher values for the percentage of fat mass and hydration of lean body mass (p < 0.05). No differences between the sexes were found in different levels of physical activity; however, males registered significantly higher values for isokinetic strength variables except for knee extensor strength. BMD was positively related to sedentary activity and negatively related to moderate and vigorous activity (r = 0.383 and r = −0.404, respectively). Light physical activity was negatively correlated with albumin (r = −0.393) and total protein (r = −0.410) levels, while moderate/vigorous activity was positively correlated with urea distribution volume (r = 0.446) and creatinine clearance (r = 0.359) and negatively correlated with the triglyceride level (r = −0.455). Conclusions: PD patients with higher levels of physical activity present better results in terms of body composition and biochemical parameters. Additional studies should be conducted to clarify the relation between physical activity level and BMD.

Gh Treatment

Abstract Background: Many girls with Turner syndrome (TS) are treated with GH to increase adult height. In addition to promoting longitudinal bone growth, GH has effects on bone and body composition. Objective: The objective was to determine how GH treatment affects bone mineral density (BMD) and body composition in girls with TS. Method: In a cross-sectional study, we compared measures of body composition and BMD by dual energy x-ray absorptiometry, and phalangeal cortical thickness by hand radiography in 28 girls with TS who had never received GH and 39 girls who were treated with GH for at least 1 yr. All girls were participants in a National Institutes of Health (NIH) Clinical Research Center (CRC) protocol between 2001 and 2006. Results: The two groups were similar in age (12.3 yr, sd 2.9), bone age (11.5 yr, sd 2.6), and weight (42.8 kg, sd 16.6); but the GH-treated group was taller (134 vs. 137 cm, P = 0.001). The average duration of GH treatment was 4.2 (sd 3.2) yr (range 1–14 yr). After adjustment for size and bone age, there were no significant differences in BMD at L1–L4, 1/3 radius or cortical bone thickness measured at the second metacarpal. However, lean body mass percent was higher (P &lt; 0.001), whereas body fat percent was lower (P &lt; 0.001) in the GH-treated group. These effects were independent of estrogen exposure and were still apparent in girls that had finished GH treatment at least 1 yr previously. Conclusions: Although GH treatment has little effect on cortical or trabecular BMD in girls with TS, it is associated with increased lean body mass and reduced adiposity.

Purpose:Although muscle mass and strength are thought to be closely related to throwing performance, there are few scientific data about these parameters in elite shot-putters. The purpose of this case report was to present longitudinal data for muscle strength and body composition in relation to performance of an elite male shot-putter.Methods:A male national champion with the best rotational shot-put performance of 20.36 m (in 2010) was followed from 2003 to 2011 (current age: 29 y). Data regarding body composition (dual X-ray absorptiometry), as well as 1-repetition-maximum muscle strength (bench press, squat, snatch) and rotational shot-put performance, were collected every February for the last 9 y, 4 wk before the national indoor championship event.Results:The athlete’s personal-best performances in squat, bench press, and snatch were 175 kg, 210 kg, and 112.5 kg, respectively. His peak total lean body mass was 92.4 kg, bone mineral density 1.55 g/cm2, and lowest body fat 12.9%. His shot-put performance over these 9 years was significantly correlated with 1-repetition-maximum squat strength (r = .93, P < .01), bench press (r = .87, P < .01), and snatch (r = .92, P < .01). In contrast, shot-put performance was not significantly correlated with any of the body-composition parameters.Conclusions:The results of this case study suggest that elite rotational shot-put performance may not be directly correlated with lean body mass. Instead, it seems that it is closely related with measures of muscle strength.

Flaxseed Flour

Obesity and osteoporosis may have their origins in early postnatal life. This study was designed to evaluate whether flaxseed flour use during lactation period bears effect on body adiposity and skeletal structure of male rat pups at weaning. At birth, male Wistar rats were randomly assigned to control and experimental (FF) groups, whose dams were treated with control or flaxseed flour diet, respectively, during lactation. At 21 days of age, pups were weaned to assess body mass, length and composition by dual-energy X-ray absorptiometry. The animals were then sacrificed to carry out analysis of serum profile, intra-abdominal adipocyte morphology and femur characteristics. Differences were considered significant when P<0.05. The FF group displayed the following characteristics (P<0.05): higher body mass, length, bone mineral content, bone area and concentrations of osteoprotegerin, osteocalcin and high-density lipoprotein cholesterol; higher levels of stearic, α-linolenic, eicosapentaenoic and docosapentaenoic acids and lower levels of arachidonic acid and cholesterol; smaller adipocyte area; and higher mass, epiphysis distance, diaphysis width, maximal load, break load, resilience and stiffness of femur. Flaxseed flour intake during lactation period promoted adipocyte hypertrophy down-regulation and contributed to pup bone quality at weaning.
