Figure 2. SR Ca2+ handling of m. vastus lateralis with terbutaline and placebo.

Figure 2

SR Ca2+ release and uptake were measured fluorometrically in crude homogenate from m. vastus lateralis at non-fatigue and at time of fatigue after three bouts of 4 min exercise at 75% of Inline graphic and a bout to fatigue at 120% of Inline graphic with terbutaline and placebo in EXP1 (n = 10). A, rate of Ca2+ release. B, the tau value of Ca2+ uptake. C, rate of Ca2+ uptake at 400 nm [Ca2+]. D, rate of Ca2+ uptake at 200 nm [Ca2+]. Data are presented as means = ± SEM. *Different (P < 0.05) from placebo. #Different (P < 0.05) from non-fatigue.
