title: How do leg press exercises comply with limited weight bearing?
abstract: OBJECTIVE
  To investigate foot loadings in different leg press settings with respect to a possible graduation of weight bearing (WB).
  
  
  METHODS
  Case series.
  
  
  METHODS
  Assessing plantar force values by means of dynamic pedobarography taken place in orthopaedic departments' rehab center.
  
  
  METHODS
  15 healthy students (9 men and 6 women, age 23 ± 2, weight 75 ± 6 kg) were recruited as participants from the medical faculty.
  
  
  METHODS
  Peak force values from normal gait (referred to as 100%) and single and double leg presses (SLP, DLP) with resistances of 10 kg, 20 kg and 40 kg, obtained with pedobarographic insoles.
  
  
  RESULTS
  Performing DLP produced foot loadings (N) of 37 ± 15 with 10 kg, 91 ± 29 with 20 kg and 203 ± 27 with 40 kg, equal to 5%, 12% and 26% of full WB. SLP result in force values of 195 ± 32 with 10 kg, 308 ± 34 with 20 kg and 516 ± 45 with 40 kg, corresponding to 25%, 40% and 67% baseline.
  
  
  CONCLUSIONS
  Leg press exercises can be performed in accordance with a given limitation of foot loading. Above mentioned conditions allow a graduation from 5% to 67% of full WB.
