“Bounce at the Bell”: a novel program of short bouts of exercise improves proximal femur bone mass in early pubertal children
Objectives : To examine the effects of a simple and inexpensive physical activity intervention on change in bone mass and structure in school aged children . Methods : Fifty one children ( n = 23 boys and 28 girls ; mean age 10.1 years ) participated in “ Bounce at the Bell ” which consisted of 10 counter-movement jumps 3 × per day ( total ∼3 min/day ) . Controls were 71 matched children who followed usual school practice . We assessed dietary calcium , physical activity , physical performance , and anthropometry in September and after 8 months of intervention ( June ) . We measured bone mineral content ( BMC ) and bone area at the lumbar spine , total body , and proximal femur . Proximal femur scans were also analysed for bone geometry and structural strength using the hip structural analysis program . Lean and fat mass ( g ) were also calculated . Results : Groups were similar at baseline and did not differ in weight , height , total body , lumbar spine , proximal femur , or femoral neck BMC . Control children had a greater increase in adjusted total body BMC ( 1.4 % ) . Intervention children gained significantly more BMC at the total proximal femur ( 2 % ) and the intertrochanteric region ( 27 % ) . Change in bone structural parameters did not differ between groups . Conclusions : This novel , easily implemented exercise program , took only a few minutes each day and enhanced bone mass at the weight bearing proximal femur in early pubertal children . A large , r and omised study of boys and girls should be undertaken powered to test the effectiveness of Bounce at the Bell in children at different stages of maturity , and in boys and girls independently
