AGING
Age-related muscle atrophy in the lower extremities and daily physical activity in elderly women – 2011 – Ikezoe
Procedure
– relationship between age-related declines in muscle thickness of lower extremities daily physical activity in elderly women
– 20 young women and 17 elderly women residing in a nursing home
– Daily physical activity was evaluated using life-space assessment (LSA) which assessed degree of independence
Results
– Biceps Femoris and Psoas were the most atrophied
– Only the Gluteus Medius was significantly associated with the LSA score
BICEPS FEMORIS, LUMBAR MULTIFIDUS
– RDL vs. Conventional Deadlift
EMG Activity of Lower Body Muscles during the Deadlift and Still-Legged Deadlift – 2013 – Bezerra
Procedure
– Repetition maximum test (1 RM) for both exercises; both exercises were performed at 70% of 1 RM
Results
Biceps Femoris: Conventional 100 . RDL 100
Lumbar Multifidus: Conventional 110 . RDL 105
BICEPS FEMORIS, GLUTEUS MAXIMUS
– RDL vs. Conventional Deadlift
An EMG and kinetic comparison of conventional and Romanian deadlifts – 2018 – Sangwoo Lee
Procedure
– Limitation: each deadlift with 70% of the Romanian deadlift one repetition maximum (1RM) determined using a 1RM testing.
Results Peak EMG
Gluteus Maximus: Conventional 50 . RDL 45
Biceps Femoris: Conventional 55 . RDL 55
+ Rectus Femoris: Conventional 60 . RDL 15
Results Peak Joint Flexion
Hip: Conventional 90 . RDL 75
Knee: Conventional 85 . RDL 30
Ankle: Conventional 110 . RDL 90
