Mean (± SD) vastus lateralis fascicle length and pennation angle during pre-, post-, and 8 weeks post-training assessments. Significant increases in fascicle length (a) and pennation angle (b) were detected after the 6-week ECC and ECCPF training programmes. After 8 weeks of detraining, no significant reduction in fascicle length occurred, which remained significantly longer than pre-training, indicating limited regression, whereas pennation angle reverted to baseline. *Significantly greater than pre-training, †significantly less than post-training, #significantly different to ECC at the same time point. Significance accepted at P < 0.05
