Objectives: The main goal of this study was to compare speed, power, and depth of the back squat performed both barefoot and in weightlifting shoes using the training protocol 5 × 5 (5 sets with 5 reps) at 70 % one-repetition maximum (1RM). Methods: Ten elite, male participants (27 ± 3.54 years old, 93 ± 10.23 kg of body weight, 179.28 ± 8.54 cm of height) were involved and assessed for the purposes of the study. All participants' 1RM back squat was not lower than 1.5 times of their body weight and they all had many years of experience using weightlifting as a part of their athletic development. The assessment was carried out at the training adaptation lab of the Department of Physiology and Biochemistry, the Faculty of Physical Education and Sport, Charles University in Prague (UK FTVS). Each participant followed the same training protocol during two sessions not less than 48 hours apart; the first one performed barefoot and the second one wearing the weightlifting shoes.
