ABSTRACT
ABSTRACT Objective This study sought to investigate the effects of vitamin D supplementation and aquatic exercise on pulmonary function in postmenopausal women. Materials and methods This prospective and controlled study included 104 women (62 ± 6.5 years) divided into three groups: a control group lacking vitamin D and calcium supplementation which remained sedentary (CG; n = 17); a control group receiving vitamin D and calcium supplementation which remained sedentary (CDG, n = 33); and a group that completed aquatic exercises three times a week and received vitamin D and calcium supplementation (DTG, n = 54). Data before and after 6 months of the study were analyzed, including serum 25-hydroxyvitamin D (25(OH)D) and calcium concentrations, peak expiratory flow (PEF), forced vital capacity (FVC), and cirtometry. Results We observed significant increases in 25(OH)D concentrations in CDG (52.9 ± 2.4 to 69.1 ± 2.2; nmol/L; p < 0.0001) and DTG groups (55.5 ± 3 to 71.5 ± 3 nmol/L; p < 0.0001). PEF increased by 7 ± 2% (p = 0.0080) in CDG group and 11 ± 2% (p < 0.0001) in DTG group, whereas FVC increased by 7 ± 2% (p = 0.0016) in the CDG group and 10 ± 2% (p < 0.0001) in the DTG group, whereas CG had no changes in any of these parameters. The increment value of cirtometry in DTG group (+43 ± 3%) were significantly (p < 0.0001) higher than those in CG (−4 ± 8%) and CDG (+4 ± 9%) groups. Conclusion Our data suggest that vitamin D supplementation improves pulmonary function parameters in postmenopausal women.

Poucos estudos longitudinais têm sido feitos, especialmente em países em desenvolvimento, para analisar o impacto do envelhecimento na aptidão física e capacidade funcional. O objetivo deste estudo foi determinar a evolução do perfil antropométrico e neuromotor da aptidão física de mulheres ativas maiores de 50 anos de idade em um período de quatro anos (1997-2001). Este estudo é parte do Projeto Longitudinal de Envelhecimento e Aptidão Física de São Caetano do Sul. A amostra foi composta por 82 mulheres de 50 a 82 anos de idade (x: 68,9 ± 6,6 anos) participantes de um programa de exercícios aeróbicos, duas vezes por semana, 50 minutos por sessão durante 5,1 ± 4,2 anos em um centro da terceira idade. As variáveis antropometricas mensuradas foram: peso corporal, estatura, índice de massa corporal (IMC), dobras cutâneas (tríceps, subescapular e suprailiaca), circunferências de braço (CB) e perna (CP), assim como de cintura e quadril, e relação cintura/quadril. Os testes neuromotores incluíram: força muscular dos membros inferiores (impulsão vertical) e superiores (dinamometria manual) e flexibilidade do tronco. A análise estatística utilizada foi o teste de hipótese para amostras dependentes, a correlação linear de Pearson e o delta percentual. O nível de significância adotado foi de p<0,01. Os resultados mostraram diminuição significativa da adiposidade (- 9,5%) após 4 anos. No entanto as outras variáveis antropométricas não apresentaram nenhuma diferença significativa em relação aos dados de base. Em relação ao perfil neuromotor houve um aumento significativo da flexibilidade (12,7%) e diminuição significativa da força muscular de membros inferiores (-22,0%), embora não houve mudanças na força de membros superiores (1,8%). Também não houve alterações das CB e CP (0,7%) após 4 anos. Não houve associação entre a força muscular de membros superiores e inferiores com a evolução das CB e CP respectivamente.
There are few longitudinal studies, especially in developing countries, which analyze the effects of aging on physical fitness and functional capacity. Thus, the purpose of this study was to determine the evolution of neuromotor performance and anthropometric variables of physical fitness in active women over 50 years old, in a four-year period (1997 to 2001). This study is part of the Longitudinal Study of Aging and Physical Fitness of São Caetano do Sul. Sample comprised 82 women, aged 50 to 82 years old (x: 68.9 ± 6.6 years). They were involved in a regular exercise program, twice a week, 50 minutes per session during 5.1 ± 4.2 years in a public senior center. The variables measured were: body weight (BW), body height (BH), sitting height (SH), body mass index (BMI), waist (WC), hip (HC),arm (AC) and leg (LC) circumferences, waist/hip ratio (WHR), and body adiposity determined through the mean of three skinfolds (triceps, subscapular and suprailiac). The neuromotor variables analyzed were: upper limb strength through handgrip strength test (HG), lower limb strength through vertical jump (VJ), trunk flexibility through sit and reach test (FLEX). Statistical analysis used were t test for dependent samples, Pearson linear correlation, and percent delta (%D). The level of significance adopted was p< 0.01. Results showed a significant (p <.01) reduction in adiposity (-9.52%) after four years. However, none of the other anthropometric variables showed any variation from the baseline data. Regarding neuromotor profile there was a significant increase (p<.01) on flexibility (12.7%) and significant decrease on lower limb strength (22.0%), although there were no changes in handgrip strength (1.8%). There were no significant changes in arm (4.3%) and leg circumferences (0.7%) after four years. There was no significant association between upper and lower limb strength and arm and calf circumferences evolution respectively.
