Electromyography (EMG) exercise evaluation is commonly used to measure the intensity of muscle contraction. Although researchers assume that biomechanically comparable resistance exercises with similar high EMG levels will produce similar strength gains over the long term, no studies have actually corroborated this hypothesis. This study evaluated EMG(More)
Little research has been reported regarding the effects of using different devices and immersion depths during the performance of resistance exercises in a water environment. The purpose of this study was to compare muscular activation of upper extremity and core muscles during shoulder extensions performed at maximum velocity with different devices and at(More)
BACKGROUND Exercises that aim to stimulate muscular hypertrophy and increase neural drive to the muscle fibers should be used during rehabilitation. Thus, it is of interest to identify optimal exercises that efficiently achieve high muscle activation levels. OBJECTIVE The purpose of this study was to compare the muscle activation levels during push-up(More)
The purpose of this study was to analyze upper extremity and core muscle activation when performing push-ups with different suspension devices. Young fit male university students (n = 29) performed 3 push-ups each with 4 different suspension systems. Push-up speed was controlled using a metronome and testing order was randomized. Average amplitude of the(More)
PURPOSE/BACKGROUND A restriction in ankle dorsiflexion range of motion (ROM) has been linked to several clinical manifestations such as metatarsalgia, heel pain, nerve entrapment, ankle joint equinus, patellar and ankle injuries. The purpose of the present study was to examine the validity and reliability of the Leg Motion system for measuring ankle(More)
High training intensity is important for efficient strength gains. Although battle rope training is metabolically demanding, no studies have quantified intensity of muscle activity during this type of training. This study analyzes muscle activity during unilateral alternating waves vs. bilateral waves of battle rope training. Twenty-one volunteers(More)
Literature that provides progression models based on core muscle activity and postural manipulations is scarce. The purpose of this study was to investigate the core muscle activity in a series of balance exercises with different stability levels and additional elastic resistance. A descriptive study of electromyography (EMG) was performed with forty-four(More)
BACKGROUND Dynamic balance has been considered a fundamental skill at all ages and is required for normal daily tasks, such as walking, running, or other sports activities. The Star Excursion Balance Test (SEBT) has been widely used in recent years to identify dynamic balance deficits and improvements and to predict the risk of lower extremity injury.(More)
