AE may improve physical functioning in healthy older people and is at least as effective as LE
BACKGROUND ageing and sedentary behaviour cause negative changes in the neuromuscular systems of healthy older adults result ing in a decrease in physical functioning .
Exercising in water ( aquatic exercise , AE ) has been shown to be effective at improving physical functioning in this population ; however , no systematic review with meta- analysis has been published .
Functional autonomy, bone mineral density (BMD) and serum osteocalcin levels in older female participants of an aquatic exercise program (AAG).
The aim of the present study was to evaluate the effects of an AAG on BMD , osteocalcin and functional autonomy in older women . The sample consisted of eighty-two post-menopausal women with low BMD , r and omly divided into two groups : the Aquatic Aerobics Group [ AAG ; n=42 ; age : 66.8±4.2years ] , su bmi tted to two weekly sessions over eight months , and the  Control Group ( GC ; n=42 ; age : 66.9±3.2years ) , which did not participate in regular exercise . BMD was measured by  Dual Energy X-ray Absorptiometry [ DXA ] of the lumbar and femur , and serum osteocalcin was measured using electrochemiluminescence . A functional autonomy assessment protocol ( GDLAM , 2004 ) was also applied . Statistical analyses used were repeated measures ANOVA and Tukey 's post hoc tests . The results showed a significant improvement in tests following the GDLAM protocol : 10 meters walk ( 10mw ) -p=0.003 ; rising from a ventral decubitus position ( RVDP ) - Δ%=0.78 , p<0.001 ; rising from a chair and moving around the house ( RCMH ) -p<0.001 and autonomy index ( AI ) -p=0.007 , with more favorable results observed in the AAG when compared to the CG . The AAG achieved the best results for BMD ; however , no inter or intragroup statistical differences were recorded for total femur -p=0.975 and lumbar L(2)-L(4)p=0.597 . For serum osteocalcin , intra and intergroup statistical differences of p=0.042 and p=0.027 were observed in the AAG , respectively . This demonstrates that an eight-month aquatic aerobic exercise program can improve functional autonomy and osteocalcin levels , although training did not improve lumbar and total femur BMD in the older women
