Sedentary Women

The aim of this study was to investigate the effects of 12-week regular step aerobic exercises on body fat values of adult sedentary women. 35 female joined to the study voluntarily who work as academic and administrative staff in Isparta Süleyman Demirel University. Step aerobic exercises were applied to the participants regularly as 12 weeks, 3 days a week, 60 minutes a day. The tempo of music in the exercises was based on “Bpm≥120”. Body fat ratios and fat mass measurements were taken with TANITA BC 418 Professional Body Analysis Device. Datas were compared by using “Repeated-Measures ANOVA” at SPSS 18 Statistics Programme. Participants’ mean of age was calculated 35,20±6,26 years and mean of lenght was calculated 168,48±5,09 cm. There were no statistical differences as a result of comparison of pre, mid and post-test weight, body fat ratio, fat mass and body mass index values taken from participants (p>0,05). As a result, according to findings handled from the research and similar studies in the literature, it can be thought that short-term Step-Aerobic exercises can cause reductions in body fat ratio values; but cannot cause reductions in weight and body mass index values because of the increment in muscle mass. Planning long-term exercises can be suggested to the future studies for being seen positive effects in these values. Additionally, for optimum physical fitness, these can be suggested to the participants that they should pay attention to their eating habits and should attend the exercises with a dietician control. ÖzetBu çalışmanın amacı, 12 haftalık düzenli step aerobik egzersizlerinin yetişkin sedanter kadınlarda vücut yağ değerlerine etkisinin incelenmesidir. Araştırmaya Isparta Süleyman Demirel Üniversitesi’nde akademik ve idari personel olarak çalışan 35 kadın gönüllü katıldı.  Katılımcılara düzenli olarak 12 hafta, haftada 3 gün, günde 60 dakika step aerobik egzersizleri uygulandı. Egzersizlerde müzik temposu “Bpm≥120” olarak baz alındı. Vücut yağ yüzdesi ve yağ kütlesi ölçümleri TANİTA BC 418 Profesyonel Vücut Analiz Cihazı ile alındı. Veriler SPSS 18.0 programında “Repeated-Measures ANOVA” kullanılarak analiz edildi. Katılımcıların yaş ortalaması 35,20±6,26 yıl ve boy ortalaması 168,48±5,09 cm olarak hesaplandı.  Katılımcılardan alınan vücut ağırlığı, vücut yağ yüzdesi, yağ kütlesi ve beden kütle endeksi ön, ara, son test değerlerinin karşılaştırılması sonucunda istatistiksel olarak farka rastlanmadı (p>0,05). Sonuç olarak, araştırmada ve literatürdeki benzer çalışmalardan elde edilen bulgulara göre, kısa dönem Step-Aerobik egzersizlerinin vücut yağ yüzdesi değerlerinde azalmaya neden olabileceği; fakat vücut ağırlığı ve beden kütle endeksi değerlerinde azalmaya neden olmamasının kas kütlesindeki artıştan dolayı olduğu düşünülmektedir. İleride yapılacak araştırmalarda bu değerlerde pozitif etkilerin görülebilmesi için daha uzun süreli egzersizlerin planlanması önerilebilir. Ek olarak, optimum fiziksel uygunluk için planlanan egzersizlerin yanı sıra katılımcılara bu tip egzersizlerde beslenme alışkanlıklarına dikkat etmeleri ve bir diyetisyen kontrolünde egzersizlere katılmaları önerilebilir.

Objective: To validate MRI fat measurement protocols using purpose built test objects and by comparison with air-displacement plethysmography (ADP) whole-body fat measurements in non-obese subjects. Methods: Test objects of known fat concentration were used to quantify the accuracy of the MRI measurements. 10 participants with a body mass index in the range 18–30 underwent whole-body MRI using two different Dixon-based sequences (LAVA Flex and IDEAL IQ) to obtain an estimate of their whole-body fat mass. The MRI determined fat mass was compared to the fat mass determined by ADP. Results: MRI test object measurements showed a high correlation to expected fat percentage (r > 0.98). The participant MRI and ADP results were highly correlated (r = 0.99) but on average (mean ± standard deviation) MRI determined a higher fat mass than ADP (3.8 ± 3.1 kg for LAVA Flex and 1.9 ± 3.2 kg for IDEAL IQ). There was no trend in the difference between MRI and ADP with total fat mass. Conclusion: The good agreement between MRI and ADP shows that Dixon-based MRI can be used effectively as a tool in physiological research for non-obese adults. Advances in knowledge: This work found that for ten non-obese subjects body mass index had no effect on the MRI determination of whole-body fat mass.

Cycling Training

The objective of the study was to assess changes in body composition, blood lipid and lipoprotein concentrations in 18–24-year-old women during the period of two-month aerobic cycling training. Material and methods. Young, healthy, nonsmoking women (n=19) volunteered to participate in this study. They were divided in two groups: experimental (E, n=10) and control (C, n=9). The subjects of group E exercised 3 times a week with intensity of the first ventilatory threshold and duration of 60 min. The group C did not exercise regularly over a two-month period of the experiment. The subjects of group E were tested before and after 2, 4, 6 and 8 weeks of the experiment. The participants of group C were tested twice with an eight-week interval. Results. Body weight, body mass index, body fat mass, and triacylglycerol (TAG) concentration decreased and high-density lipoprotein cholesterol (HDL-ch) concentration increased after the 8-week training program in the experimental group (P<0.05). Blood total cholesterol (Tch) and low-density lipoprotein cholesterol (LDL-ch) concentrations did not change significantly. Body weight and body mass index started to decrease after 2 weeks of the experiment, but significant changes were observed only after 6 and 8 weeks. Body fat mass was significantly decreased after 2 and 8 weeks of aerobic training. A significant increase in HDL-ch concentration was observed after 4, 6, and 8 weeks. A significant decrease in TAG concentration was observed after 2-week training. No significant changes in all the parameters except TAG (it was slightly increased) were seen in the control group. Conclusions. The two-month aerobic cycling training (within VT1, 60-min duration, three times a week) may induce significant changes in the parameters of body composition – body weight, body mass index, body fat mass, and blood lipids – in young women. The following significant changes were observed: TAG level decreased after 2 weeks, body mass and body mass index decreased after 6 weeks, body fat mass decreased and HDL-ch level increased after 8 weeks. Peak oxygen uptake increased after 4 weeks.

General Physical

Childhood obesity is a key public health issue around the globe in developed and developing countries (Dugan, 2008). The recent worldwide increase in the prevalence of childhood obesity may be due in part to a decrease in children’s physical activity levels (Ball et al., 2001). It is necessary to develop early interventions to improve physical fitness in children and to prevent the increase of childhood obesity (Brunet et al., 2006). So, the aim of this study was to evaluate the body composition and physical fitness of children aged 5—7 years and to estimate the interaction between body composition components and physical fitness tests. Participants: 216 children participated in this study: 104 girls, mean age 5.90 ± 0.63 years and 112 boys — mean age 5.98 ± 0.50 years from Kaunas city (Lithuania) preschools. Methods: all the subjects have been measured for their height, body mass, waist circumference (WC) and skinfolds at 2 different places — triceps and subscapular. Body mass index (BMI) and percentage body fat mass (BFM) were evaluated. All the participants did four physical fitness tests including speed shuttle run, 20 meters distance run, standing long jump and throwing 1 kg ball. General physical fitness level was evaluated based on B. Sekita (1988) methods. Results. Results showed that BMI did not significantly differ between boys and girls, and was evaluated as “optimal” for both groups. BFM was significantly higher in girls (p < 0.001), and WC did not differ between genders. But WC had a tendency to increase with age in both boys and girls. Strong relationship was observed between BMI and BFM (r = 0.660, r = 0.660 respectively; p < 0.01), and between BMI and WC (r = 0.703, r = 0.826 respectively; p < 0.01) for both boys and girls. The results of physical tests showed that boys did all the tests better than girls (p < 0.01). When we evaluated the general physical fitness of each child, the results indicated that their physical fitness waslow, evaluated as “good enough” for most boys and girls. General physical fitness of children negatively but slightly correlated with BFM (r = –0.201; p < 0.001), it indicated that higher BFM determined lower evaluation of general physical fitness.Conclusions. Optimal body weight, according to body mass index, percentage body fat mass and waist circumference, was established for the bigger part of children, aged 5—7 years old. This study shows that physical fitness of children was low — evaluated as “good enough” and negatively correlated with body fat mass, showing that high body fat mass negatively impacted physical fitness.Key words: body mass index, percentage body fat mass, waist circumference, physical fitness.

(1) Objective: This study analyzes the evolution of the body mass index (BMI) throughout the academic year associated with changes in the lifestyle associated with the place where students live during the course, lifestyle design, and health strategies for the university community. (2) Methods: A total of 93 first-year nursing students participated in this study. Data were collected throughout the course by administering self-reported questionnaires about eating habits and lifestyles, weight, and height to calculate their BMI and place of residence throughout the course. Data were analyzed using statistical analysis (Mann–Whitney, chi-square, Student’s t-test, repeated-measures analysis of variance, and least significant difference tests). (3) Results: We found that the mean BMI increases significantly throughout the course among all students regardless of sex, age, eating habits, or where they live during the course. At the beginning of the course, the mean BMI was 22.10 ± 3.64. The mean difference between the beginning of the course and the middle has a value of p-value < 0.015 and between the middle of the course and the end a p-value < 0.009. The group that increased the most is found among students who continue to live in the family nucleus rather than those who live alone or in residence. Students significantly changed their eating and health habits, especially those who live alone or in residence. (4) Conclusions: There is an increase in BMI among students. It is necessary to carry out seminars or talks that can help students understand the importance of good eating practices and healthy habits to maintain their weight and, therefore, their health, in the short, medium, and long term and acquire a good quality of life.

Evidence of a gene-exercise interaction for traits related to body composition is limited. Here, the association between the lipoprotein lipase (LPL) S447X polymorphism and changes in body mass index, fat mass, percent body fat, abdominal visceral fat measured by computed tomography, and post-heparin plasma LPL activity in response to 20 wk of endurance training was investigated in 741 adult white and black subjects. Changes were compared between carriers and noncarriers of the X447 allele after adjustment for the effects of age and pretraining values. No evidence of association was observed in men. However, white women carrying the X447 allele exhibited greater reductions of body mass index ( P= 0.01), fat mass ( P = 0.01), and percent body fat ( P = 0.03); in black women, the carriers exhibited a greater reduction of abdominal visceral fat ( P = 0.05) and a greater increase in post-heparin LPL activity ( P = 0.02). These results suggest that the LPL S447X polymorphism influences the training-induced changes in body fat and post-heparin LPL activity in women but not in men.

Androgen Levels

AbstractThe association between circulating androgen levels and fat distribution in women has been widely inconsistent among existing studies.We sought to investigate the relation between plasma adrenal and gonadal androgen levels and body fat distribution, as well as abdominal adipocyte characteristics.Paired omental and subcutaneous adipose tissue samples were surgically obtained from 60 women (age, 47±5 years; body mass index, 26±5 kg/mSignificant negative associations were found between plasma dihydrotestosterone (DHT) levels and total adiposity (body mass index, r=–0.35, p<0.05; fat mass, r=–0.31, p<0.05) as well as computed tomography assessments of abdominal adiposity (r=–0.30, p<0.05 and r=–0.44, p<0.005 for subcutaneous and visceral adipose tissue area, respectively). The association between DHT levels and visceral adipose tissue area was independent of total body fat mass. A significant negative association was also observed between plasma DHT and omental adipocyte diameter (r=–0.27, p<0.05). When expressed as the omental/subcutaneous ratio, heparin-releasable lipoprotein lipase activity was negatively and significantly related to plasma DHT, androstenedione, and dehydroepiandrosterone (DHEA) levels.Abdominally obese women with large, metabolically active omental adipocytes appear to be characterized by reduced endogenous levels of DHT. The assumption that high androgen levels are associated with an android body fat distribution pattern in women should be critically re-examined.
