Establishing the Reliability and Limits of Meaningful Change of Lower Limb Strength and Power Measures during Seated Leg Press in Elite Soccer Players

Table 1. Keiser Air 420 example 10 repetition maximal power test protocol.

Repetition Number	1^st Warm Up	2^nd Warm Up	1^st	2^nd	3^rd	4^th	5^th	6^th	7^th	8^th	9^th	10^th	All Subsequent Reps
Resistance (kg) based on 250kg 1RM	41**	41	41	64	87	110	133	157	180	203	226	250	Previous rep+23.2*
