Abstract

We investigated the effects of eccentric contractions (ECs) on bone metabolism markers and the relationship between bone metabolism and skeletal muscle related protein. Seventeen young untrained men were divided into two groups and performed either 60 or 30 maximal ECs. We measured serum levels of osteocalcin (OC), bone alkaline phosphatase, cross-linked N-telopeptide of type I collagen (NTx), and tartrate-resistant acid phosphatase 5b (TRACP-5b), growth hormone (GH), and insulin-like growth factor-1 (IGF-1). Blood samples were collected for up to five days after ECs. OC with 60 ECs were significantly higher than with 30 ECs (2 hours; p
