Baseline tension and tension–time indices for stretch of the calcaneal tendon during experiments recorded from muscle spindles before and 30 and 60 min after amiloride injections (0.5 μg kg⁻¹ or 5.0 μg kg⁻¹; i.a.)

	Control	Amiloride 30 min	Amiloride 60 min
Amiloride large dose (5 μg kg−1)
Muscle spindle	N = 10	N = 10	N = 10
Baseline tension (kg)	0.40 ± 0.09	0.38 ± 0.08	0.38 ± 0.08
Tension–time index (kg s)	84 ± 6	88 ± 7	83 ± 7
Amiloride small dose (0.5 μg kg−1)
Muscle spindle	N = 5	N = 5	N = 5
Baseline tension (kg)	0.26 ± 0.06	0.23 ± 0.07	0.24 ± 0.07
Tension–time index (kg s)	57 ± 4	59 ± 3	59 ± 4

There were no significant differences (P > 0.05) between corresponding means.
