Bone density, balance and quality of life of postmenopausal women taking alendronate participating in different physical activity programs

Background: The objective of this study was to determine the effects of different physical activity (PA) programs on bone density, balance and quality of life of postmenopausal women taking concomitant alendronate. A quasi-experimental study was conducted with 35 volunteers divided into four groups: practitioners of resistance training (RTG, n = 9, 49.8±4.2 years), judo (JUG, n = 11, 52.2±5.3 years), water aerobics (WAG, n = 8, 57.1±7.4 years) and the control group (CG, n = 7, 53.8±4.4 years). Methods: The following assessment tools were used: bone mineral density (BMD) measured by dual X-ray absorptiometry of the spine and proximal femur, the ‘Osteoporosis Assessment Questionnaire’ (OPAQ) and the ‘Static Balance Test with Visual Control’. The physical activities were planned for 12 months in cycles with different intensities. A two-way analysis of variance (ANOVA) was used for analysis between groups, and a Scheffé post-hoc test was used for multiple comparisons. Results: The multiple comparisons results showed that the RTG and JUG groups were significantly more efficient in the variables studied, including: lumbar BMD (Δ% = 6.8%, p = 0.001), balance (Δ% = 21.4%, p = 0.01), OPAQ (Δ% = 9.1%, p = 0.005) and lumbar BMD (Δ% = 6.4%, p = 0.003), balance (Δ% = 14%, p = 0.02) and OPAQ (Δ% = 16.8%, p = 0.000) compared with the CG. Furthermore, the RTG (Δ% = 4.8%, p = 0.02) was significantly better than the WAG for the neck of femur BMD, and the JUG (Δ% = 16.8, p = 0.0003) also demonstrated superiority to the WAG in the OPAQ. Conclusions: The physical activities studied appear to improve BMD, balance and quality of life of postmenopausal women taking a bisphosphonate. In this small sample, the RTG and the JUG groups were superior to the other groups.

Efeitos do treinamento resistido sobre variáveis relacionadas com a baixa densidade óssea de mulheres menopausadas tratadas com alendronato

Osteoporosis is a chronic disease of the human skeleton. OBJECTIVE: To verify the effects of resistance training on bone mineral density (BMD), muscular strength, balance and quality of life in menopausal women taking Alendronate. MATERIALS AND METHODS: Sixteen female volunteers participated in the study. The volunteers were separated into two groups: resistance training participants (n=9; 49.7±4.2 years) and control group (n=7; 53.8±4.4 years). The following evaluation instruments were used: absorptiometry-DXA (which measured the lumbar spine L2-L4, neck femur, Wards triangle and major trochanter), the Osteoporosis Assessment Questionnaire (OPAQ) and a balance test. The training was applied in 12 months, divided in six cycles with intensity of 70-90% of the maximum load (10RM). Parametric tests for intra-group analysis (t or Wilcoxon) and (Anova) for inter-groups, were used. RESULTS: Significant differences in the resistance training group were found in the bones variables: lumbar L2-L4 (6.8%, p=0.001), neck femur (4.8%, p=0.005) and trochanter (0.76%, p=0.005). In addition, significant differences were also found for body balance (21.4%, p=0.001), quality of life (9.1%, p=0.001) and all muscular strength measurements, such as in leg press 45° (49.3%, p<0.001). CONCLUSION: The results suggest that the methodology applied to resistance training can be recommended for menopausal women with low BMD.

Efeito do modelo de periodização com cargas seletivas sobre capacidades motoras durante um mesociclo preparatório em jogadores de futsal

The aim of this study was to verify the effect of selective loads model in profes- sional futsal players, during a preparatory mesocycle. Nine futsal professional players (23±2 anos), from the team of Federation Paulista of soccer indoor championship, composed the sample, characterized by intentional. The players were evaluated in two moments although of a preparatory mesocycle, microcycle 2 (PRE) and microcycle 7 (POS), by the tests of intermittent aerobic fitness, horizontal jump, one leg triple jump, velocity of 15m, agility and anaerobic power. The statistical analysis included the Student-t and Wilxocon tests (P<0.05). The results of horizontal jump, intermittent aerobic fitness and medium power improved, the velocity at 15 m decreased. The select loads model is a good option for the periodization to preparatory mesocycle in futsal.

Factors that contribute to low bone density in postmenopausal women in different Amazonian communities

Background: The aim of this study was to verify socioeconomic differences, nutrition, body balance and quality of life (QoL) in postmenopausal women with low bone mineral density (BMD) in two Amazonian communities. Methods: A total of 42 female volunteers participated in the study. The volunteers were separated into two groups: Villa (n = 20; 53 ± 5.5 years) and City (n = 22; 56 ± 7.9 years). The following evaluation instruments were used: dual energy X-ray absorptiometry (DXA); a socioeconomic questionnaire; a QoL questionnaire; a dietary habits questionnaire; and a balance test. Parametric and nonparametric tests were used. Results: The data showed significant differences in socioeconomic level (Δ%=+15.9%, p = 0.000), lumbar spine L2-L4 (Δ% = +0.10%, p = 0.007), balance (Δ% = +4.3%, p = 0.03) and some important aspects of nutrition, such as the consumption of milk (Δ%=+34%, p = 0.01) and alcohol (+14.8%, p = 0.0001). These significant differences also contributed to the total QoL score (Δ%=+76.2%, p = 0.000) and the majority of the QoL-related functions. Conclusion: This study verified that socioeconomic level, nutritional status, physical activity levels and QoL can influence the BMD of postmenopausal women. The study suggests new strategies for official health organizations to use in order to prevent and treat osteoporosis. In addition, this study can provide an orientation to physical activity, nutrition and medical professionals.

Futebol e a construção da imagem de treinadores pela mídia: um estudo a partir das notícias de um site de grande visitação na web

The relationship between sport and media is inseparable today. Therefore, this study aimed to quantify the number of news reports about male professional soccer, and analyze the construction of the image associated with soccer coaches. To this end, every sports news from a largely accessed website was collected for 30 days. It was concluded that, in Brazil, these news are directed to male professional soccer and its coaches, with the ideas concerning the latter being mainly related to their competence and the tactical/technical articulation of the team.

Bone variables after a water aerobics program in postmenopausal women undergoing pharmacological treatment

AimTo determine the effects of water aerobics on bone mineral density (BMD) and quality of life (QoL) in postmenopausal women undergoing pharmacological treatment.MethodsIncluded in the study were 84 women volunteers who were separated into two groups: water aerobics (43 women, age 55.4 ± 6.4 years) and a control group (41 women, age 54.3 ± 4.5 years). Dual X-ray absorptiometry and the “Osteoporosis Assessment Questionnaire” were used for evaluation. Water aerobics training was scheduled for 12 months. Analysis of variance and the Kruskal-Wallis test were used.ResultsNo significant intergroup differences were found in the lumbar spine (L2–L4) and femoral neck. However, favorable differences in the trochanter (0.018% difference, p = 0.01) and in QoL (3.4% difference, p = 0.01) were found in the water aerobics group.ConclusionThe results suggest that water aerobics may be beneficial for QoL and BMD in the trochanter in postmenopausal women. However, more recommendation criteria need to be established for BMD.

Barriers faced by brazilian female coaches

No Brasil, a representatividade de mulheres como treinadoras esportivas e muito baixa. Diante desse cenario, este estudo teve como objetivo identificar e analisar as barreiras encontradas por treinadoras brasileiras em sua carreira.
