Moderate Resistive Training Maintains Bone Mineral Density and Improves Functional Fitness in Postmenopausal Women
Danilo Sales Bocalini,Andrey Jorge Serra,Leonardo dos Santos
Journal of Aging Research , 2010, DOI: 10.4061/2010/760818
Abstract: Twenty five subjects were randomized to untrained (UN) and resistive-trained (RT) groups. The RT group exercised three sessions per week at 60%–70% of the load according to individual 1RM test during 24 weeks. Both groups were evaluated before and after protocol period assessing lumbar spine (LS) and femoral neck (FN) BMD by dual-energy X-ray absorptiometry, ?max, and neuromuscular fitness. After 24 weeks, there were significant reductions in LS ( loss) and FN BMD ( loss) for UN but no change was found in the TR (LS: and FN: loss). The UN group had no changes in neuromuscular performance. However, RT exhibited a significant improvement on the functional fitness parameters evaluated, with the exception of agility. Our results indicate RT suppresses the decline in BMD and simultaneously improves the functional fitness of postmenopausal women without hormone replacement therapy, which may reduce fall risk and related bone fractures. 1. Introduction Aging is often associated with reductions in bone mineral density (BMD) and muscle mass [1] and, consequently, with higher risk for falls and bone fractures [2].Currently, bone demineralization (osteopenia) and muscle loss (sarcopenia) affect over 34 million people which results in more than 2 million bone fractures a year in the United States (NIH/NIAMS, 2009). With aging, while both sexes lose bone, women exhibit loss rates substantially higher than men, suffering a greater risk for osteoporosis after menopause [3–5]. Some studies suggest that the reduced ovarian function and serum hormones levels accelerate the rate of bone loss and may also be involved in the decline of muscle mass and strength [6]. Basic exercise guidelines recommended by the American College of Sports Medicine for healthy adults and elderly people emphasize that training programs consist of resistance, strength, aerobic, and flexibility exercises. Resistive training (RT) is an exercise modality that imposes heavy loads upon the skeleton and, consequently, should increase both body strength and muscle mass in older women. Similar to other studies [1, 7, 8] our group demonstrated that intense RT promotes several benefits in postmenopausal women such as improved body composition parameters and muscular strength with a significant preservation of BMD [9]. However, the literature remains equivocal, since other investigators did not report such findings [10–12]. Furthermore, the effectiveness of resistive training on the bone health simultaneously evaluated with functional fitness tests in postmenopausal women who are not using drugs that affect

Universidade S o Judas Tadeu (USJT), S o Paulo, SP, BrazilAim: The aim of this study was to investigate the impact of circuit-based exercise on the body composition in obese older women by focusing on physical exercise and body weight (BW) gain control in older people.Methods: Seventy older women (>60 years old) voluntarily took part in the study. Participants were randomized into six different groups according to body mass index (BMI): appropriate weight (AW) control (AWC) and trained (AWT) groups, overweight (OW) control (OWC) and trained (OWT) groups, and obesity (O) control (OC) and trained (OT) groups. The exercise program consisted of 50 minutes of exercise three times per week for 12 weeks. The exercises were alternated between upper and lower body using rest between sets for 40 seconds with intensity controlled by heart rate (70% of work). The contraction time established was 5 seconds to eccentric and concentric muscular action phase. The following anthropometric parameters were evaluated: height (m), body weight (BW, kg), body fat (BF, %), fat mass (FM, kg), lean mass (LM, kg), and BMI (kg/m2).Results: The values (mean ± standard deviation [SD]) of relative changes to BW ( 8.0% ± 0.8%), BF ( 21.4% ± 2.1%), LM (3.0% ± 0.3%), and FM ( 31.2% ± 3.0%) to the OT group were higher (P < 0.05) than in the AWT (BW: 2.0% ± 1.1%; BF: 4.6% ± 1.8%; FM: 7.0% ± 2.8%; LM: 0.2% ± 1.1%) and OWT (BW: 4.5% ± 1.0%; BF: 11.0% ± 2.2%; FM: 16.1% ± 3.2%; LM: 0.2% ± 1.0%) groups; additionally, no differences were found for C groups. While reduction (P < 0.03) in BMI according to absolute values was observed for all trained groups (AWT: 22 ± 1 versus 21 ± 1; OWT: 27 ± 1 versus 25 ± 1, OT: 34 ± 1 versus 30 ± 1) after training, no differences were found for C groups.Conclusion: In summary, circuit-based exercise is an effective method for promoting reduction in anthropometrics parameters in obese older wome

Methods: Twenty-three untrained (n = 12) and trained (n = 11) normotensive women performed two walking sessions in water and on land at 40% of peak VO2 for 45 minutes. Systolic and diastolic blood pressure and mean arterial pressure were measured 15, 30, 45, and 60 minutes after the exercise sessions. Results: No differences were found between the groups for age and anthropometric parameters, but peak VO2 for the trained women (45 ± 8 mL/kg/minute) was higher than for the untrained women (31 ± 3 mL/kg/minute). No differences were found between the groups with regard to systolic and diastolic blood pressure and mean arterial pressure after water immersion. The heart rate in the trained group (62 ± 3 beats per minute [bpm]) was significantly lower (P < 0.05) than in the untrained group (72 ± 4 bpm) on land, and after water immersion, this difference disappeared (58 ± 5 bpm in the trained women and 66 ± 5 bpm in the untrained women). Sixty minutes after water-walking, systolic blood pressure (108 ± 8 mmHg vs 97 ± 3 mmHg), diastolic blood pressure (69 ± 5 mmHg vs 62 ± 5 mmHg), and mean arterial pressure (82 ± 6 mmHg vs 74 ± 4 mmHg) decreased significantly with rest in the untrained group, and no differences were found after land-walking. In the trained group, significant (P < 0.05) differences were found only for systolic blood pressure (110 ± 9 mmHg vs 100 ± 9 mmHg) after 60 minutes of water-walking; decreases in systolic blood pressure were found after 45 minutes (99 ± 7 mmHg) and 60 minutes (99 ± 6 mmHg) compared with rest (107 ± 5 mmHg) after land-walking. Conclusion: Single water-walking and land-walking sessions induced important hypotension following exercise. Additionally,

Abstract: Elevated concentrations of testosterone and its synthetic analogs may induce changes in cardiovascular function. However, the effects of the combination of anabolic/androgenic steroid (AAS) treatment and exercise training on systolic and diastolic cardiac function are poorly understood. In the present study, we aimed to investigate the effects of low-dose steroid treatment (stanozolol) on cardiac contractile parameters when this steroid treatment was combined with exercise training in rats and the effects of chronic steroid treatment on the Frank-Starling (length-tension curves) relationship. Male Wistar rats were randomly assigned to one of four groups: U (untrained), US (untrained and treated with stanozolol 5 mg/kg/week), T (trained, 16 m/min/1 h) and TS (trained and treated with stanozolol 5 mg/kg/week). Continuous exercise training was conducted 5 days/week for 8 consecutive weeks. The speed of the treadmill was gradually increased to a final setting of 16 m/min/1 h. Experiments were divided into two independent series: 1) central hemodynamic analysis for mean arterial blood pressure (MAP) and cardiac output (CO) measurements and 2) isolated papillary muscle preparation in Krebs solution. Stanozolol treatment significantly increased the MAP and the heart size in untrained and trained rats (U 113±2; T 106±2; US 138±8 and TS 130±7 mmHg). Furthermore, stanozolol significantly decreased developed tension and dT/dt (maximal and minimal) in U rats. However, the developed tension was completely restored by training. The Frank/Starling relationship was impaired in rats treated with stanozolol; however, again, training completely restored diastolic function. Taken together, the present data suggest that AAS treatment is able to decrease cardiac performance (systolic and diastolic functions). The combination of stanozolol and physical training improved cardiac performance, including diastolic and systolic functions, independent of changes in central hemodynamic parameters. Therefore, changes in ventricular myocyte calcium transients may play a cardioprotective role.
