We examined the effects of a 12-week program of Nordic hamstring exercises (NHE), administered before or after football training, upon eccentric hamstring strength, muscle activity, and architectural adaptations. Amateur soccer players were randomized into three groups. The control group (CON; n=11) undertook core stability exercises, whereas a periodized NHE program was delivered either before...

Evaluation of The Acute Hormonal Responses To Concentric, Eccentric And Concentric_ Eccentric Muscle Actions in Healthy Young Men Introduction: Resistance exercise is a potent stimulus for acute increase in the concentrations of circulating hormones such as Growth Hormone (GH) and Testosterone. Conventional resistance exercise is performed using sequential concentric (CON) and eccentric (EC...

Over the last 20 years a number of studies have been published using progressive eccentric exercise protocols on motorized ergometers or similar devices that allow for controlled application of eccentric loads. Exercise protocols ramp eccentric loads over an initial 3 weeks period in order to prevent muscle damage and delayed onset muscle soreness. Final training loads reach 400-500 W in rehabi...

Tendinopathy is one of the most frequent overuse injuries associated with sport. It is a failure of a chronic healing response associated with both chronic overloaded and unloaded states. Although several conservative therapeutic options have been proposed, very few of them are supported by randomized controlled trials. Eccentric exercises provide excellent clinical results both in athletic and...

OBJECTIVE To assess and compare the effects of 6 mo of Pilates and calisthenics on multijoint coordination and proprioception of the lower limbs at the 3rd and 6th mo of training. DESIGN Randomized, controlled, assessor-blinded, repeated-measures. SETTING University research laboratory. PARTICIPANTS AND INTERVENTION Healthy, sedentary, female participants age 25-50 y were recruited and ra...

STUDY DESIGN Systematic Review. INTRODUCTION Lateral epicondylosis (LE) is relatively common with an annual incidence in the general population of 1% to 3%. Systematic reviews have identified exercise is effective, but have not established specific exercise parameters. PURPOSE The purpose of this systematic review was to synthesize the quality and content of clinical research addressing typ...

Inflammation and pain induced by delayed onset muscle soreness (DOMS) can be induced by eccentric exercise or an unaccustomed activity. The condition can causes problems in exercising and for athletes. The purpose of this study was to assess the effect of 150mg curcumin supplementation immediately after intensive eccentric exercise. Evaluations were made for total antioxidant Capacity (TAC), mu...

BACKGROUND Core stabilization has been utilized for rehabilitation and prevention of lower limb musculoskeletal injuries. Previous studies showed that activation of the abdominal core muscles enhanced the hip muscle activity in hip extension and abduction exercises. However, the lack of the direct measurement and quantification of the activation level of the abdominal core muscles during the ex...

The forward walking lunge (WL) and split squat (SSq) are similar exercises that have differences in the eccentric phase, and both can be performed in the ipsilateral or contralateral carrying conditions. This study aimed to determine the effects of dumbbell-carrying position on the kinematics and electromyographic (EMG) amplitudes of the gluteus medius (Gmed), vastus medialis (VM), vastus later...

CONTEXT The role of the rotator cuff is to provide dynamic stability to the glenohumeral joint. Human and animal studies have identified sarcomerogenesis as an outcome of eccentric training indicated by more torque generation with the muscle in a lengthened position. OBJECTIVE The authors hypothesized that a home-based eccentric-exercise program could increase the shoulder external rotators' ...
