The Stanford study placed 311 overweight, premenopausal women with
similar body statistics on one of four diets: Atkins (very low - carb), the Zone (low - carb), the LEARN diet (low - fat, national guidelines) and the Ornish diet (very low - fat).
The descriptive
statistics report that the inverted row (25 %) and the suspension trainer inverted row (22 - 28 %) produce
similar biceps muscle activity, while a lower angle of pull (the
body oriented more horizontal) produced greater muscle activity (41 %) indicating that greater load produces greater biceps muscle activity in this exercise.
