Electromyographic Activity Of Elderly Vastus Lateralis Oblique Muscle Submitted To Periodized Resistance Training, Cláudio De Oliveira Assumpção, João Bartholomeu Neto, Christiano Bertoldo Urtado, Sérgio H. Borin
International Journal of Exercise Science: Conference Proceedings
Resistance training (RT) is recommended for elderly with the objective to increase muscle strength and power trough neuromuscular adaptations, inducing increased motor and functional capacities. The electromyography (EMG) is an important instrument to analyze muscle function after diverse exercise training protocols. The objective of the present study was to analyze electromyographic activity of vastus lateralis oblique muscle (VLO) during maximal voluntary isometric contraction of elderly women submitted to 12 weeks of periodized RT. 16 women aged 65.5±3.6 years with a minimum of one year of previous experience in strength training were selected, they performed 24 sessions of RT divided in …

Stability Ball Sitting Versus Chair Sitting During Sub-Maximal Arm Ergometry, Charles R.C Marks, Kristina E. Hylland, Jacob Terrell
International Journal of Exercise Science
Purpose: It was predicted that sitting on a stability ball during arm ergometry would elevate cardiovascular parameters when compared to sitting on a chair and that this would be associated with greater recruitment of trunk and leg skeletal muscles. Methods: Open-circuit spirometry, video taping, blood pressure, heart rate, and EMG were conducted during rest and four minute stages of 15 W, 30 W, and 45 W using a Monark arm ergometer. Twenty-six apparently healthy adults exercised twice, once sitting on a stability ball and the other sitting on a chair (order randomized), with 45 to 60 minutes of rest between. …
