Summary of the kinematic features and swimming performance of the four strokes

Euglenid		γmax	U	, %	, %
#1	0.58|0.76|0.95	2.5	0.16	0.71	0.24
#2	0.60|0.72|0.87	3.0	0.27	1.6	0.57
#3	0.61|0.63|0.65	3.0	0.25	1.6	0.48
#4	0.50|0.51|0.53	3.4	0.40	2.0	0.76

U denotes the net displacement in one stroke, in units of body length (the diameter of a sphere with the surface area of the swimmer). Eff_L denotes the Lighthill efficiency, accounting for either the outer, or both the outer and inner fluids. denotes the average reduced volume during the stroke.
