Squats with more anteriorly placed loads resulted in:
- Decreased trunk flexion.
- Decreased pelvis anterior tilt angles.
- Increased low-back moments.
- Similar lower extremity moments compared to squats with more posteriorly placed loads.
FIRST:
- The transformer bar imposes similar lower extremity loading as a straight-bar back squat.
- Therefore, can be considered as an alternative training strategy for people with upper extremity limitations.
SECOND:
- Changing anterior-posterior load placement may not induce as many changes in low-back and lower extremity moments as thought.
- As individuals can adjust their trunk and pelvis angles to mediate the effects of load placements on joint moments.
- Additional instruction and feedback may be needed to achieve greater effects of load placement manipulation on low-back and lower extremity joint moments.
THIRD:
- The straight-bar front squat has more knee loading, but less ankle and hip loading in the descending phase compared to the other squats.
LAST:
- Anteriorly placed loads may result in greater low-back moments.
- While, posteriorly placed loads may demonstrate greater trunk flexion and pelvis anterior tilt.
- This should be taken into consideration for people with low-back impairment.
