Primary Outcome Measures

Name	Time	Method
<p>Lumbar spine bone mineral density.</p><br>

Secondary Outcome Measures

Name	Time	Method
<p>Blood parameters of bone turnover: Procollagen type I N propeptide (P1NP),<br /><br>carboxy-terminal crosslinking telopeptide of type I collagen (CTX-I).<br /><br>Countermovement jumps will assess the effect of the intervention on jump height<br /><br>as a marker of lower body power.</p><br>
