Muscle Activity In Single- Vs. Double-Leg Squats, Bradley A. Deforest, Gregory S. Cantrell, Brian K. Schilling
International Journal of Exercise Science
International Journal of Exercise Science 7(4) : 302-310, 2014. Muscular activity, vertical displacement and ground reaction forces of back squats (BS), rear-leg elevated split squats (RLESS) and split squats (SS) were examined. Nine resistance-trained men reported for two sessions. The first session consisted of the consent process, practice, and BS 1-repetition maximum testing. In the second session, participants performed the three exercises while EMG, displacment and ground reaction force data (one leg on plate) were collected. EMG data were collected from the gluteus maximus (GMX), biceps femoris (BF), semitendinosus (ST), rectus femoris (RF), vastus lateralis (VL), vastus medialis (VM), tibialis …

International Journal of Exercise Science 6(2) : 114-125, 2013. Weightlifters have commonly believed that changing joint position can alter specific muscle activation. The magnitude of force produced by a muscle is highly dependent upon the length of the muscle. The purpose of this study was to determine the effect of foot positioning on muscle activation of the superficial quadriceps as measured by surface electromyography (sEMG) during a functional squatting movement in healthy adults. Twenty physically active asymptomatic adults (7 females and 13 males) were included in the study while four different foot positions (Neutral, Internally Rotated, Externally Rotated, and Staggered) …

Isokinetic Fatigue Characteristics For The Leg Extensors Versus Flexors, Elias M. Carrillo, Matt S. Stock, Jacob Adam Mota, Kendra D. Olinghouse, Alexander S. Drusch, Brennan J. Thompson
Isokinetic Fatigue Characteristics For The Leg Extensors Versus Flexors, Elias M. Carrillo, Matt S. Stock, Jacob Adam Mota, Kendra D. Olinghouse, Alexander S. Drusch, Brennan J. Thompson
International Journal of Exercise Science: Conference Proceedings
Maximal isokinetic muscle actions are often used in research studies to examine fatigability and even estimate muscle fiber-type. However, the majority of previous investigations have examined these topics for the leg extensors (i.e., quadriceps), and we are unaware of investigations that have specifically assessed the fatigue characteristics for the flexors (i.e., hamstrings). The purpose of this study was to compare the percent decline values for the leg extensors versus flexors for 50 and 100 repeated, maximal concentric isokinetic muscle actions. Fifteen healthy men (mean ± SD age = 23 ± 3 years; body mass = 94.1 ± 11.9 kg) with …
