Perceived Loading & Muscle Activity during Hip Strengthening: Elastic vs. Machine – 2013 – Brandt, Andersen
Procedure
– compare hip muscle activity with light load, moderate load, heavy load, near max load
– estimating 10 RM can be time‐consuming and difficult especially in patients that experience pain due to injured or healing tissues
– perceived loading using the Borg category ratio 10 scale (Borg CR10 scale)9 can be an alternate tool for estimating the intensity of a given exercise
– testing 11 muscles at the hip, thigh and trunk during hip adduction and hip abduction exercises
– 16 untrained women, using elastic resistance and isotonic exercise machines
Results for Moderate Load

– Side Steps with Band around the Thighs
Which Exercises Target the Gluteal Muscles While Minimizing Activation of the Tensor Fascia Lata? – 2013 – Selkowitz
Procedure
– determine which exercises are best for activating the gluteus medius and the superior portion of the gluteus maximus, while minimizing activity of the tensor fascia lata (TFL).
Fine Wire Electrodes
– SUP-GMAX: superior and lateral to midpoint of a line drawn b/n the posterior superior iliac spine and posterior greater trochanter.
– GMED: inserted 2.5 cm distal to the midpoint of the iliac crest (ie, middle portion).
– TFL: inserted distal and slightly lateral to the anterior superior iliac spine and medial and superior to the greater trochanter.
| Sidestep with elastic resistance around the thighs in a squatted position | Starting position was in a squatted position, as described above for the squat. The subject then stepped to the side with one limb, followed in the same direction by the other limb, both step lengths approximately 50% of the starting-position distance between the feet (see squat). Knees were kept aligned with the ipsilateral second toe. If a sidestep with each limb in succession was considered a stride, then the subject performed a total of 2 strides in one direction, followed by 2 strides in the opposite direction to return to the starting position. This activity cycle was performed a total of 3 times. The same method of elastic resistance was used in this exercise as in the clam exercise, because there was otherwise little resistance to the sideways movement |
