We find that : ( i ) relaxed cross - bridges , but not active ones , are statistically better ordered in muscle where the RLC is dephosporylated compared with phosphorylated RLC ; ( ii ) relaxed phosphorylated and dephosphorylated cross - bridges rotate equally slowly ; and ( iii ) active phosphorylated cross - bridges rotate considerably faster than dephosphorylated ones during isometric contraction but the duty cycle remained the same , suggesting that both phosphorylated and dephosphorylated muscles develop the same isometric tension at full Ca ( 2 + ) saturation .
 Chemical: Ca ( 2 + )
