background: the purpose of this study was to investigate the ratio of electromyography (em g) activities of the vastus medialis obliqus (vmo) and vastus lateralis (vl) within seven angles of knee joint range of motion using isometric contraction in open kinetic chain (ok c) and closed kinetic chain (ckc). methods: the dominant knees of 44 healthy female subjects (mean age: 24.84 with range: 20-...

هدف: کبد از حساس‌ترین بافت‌های هدف فشار اکسایشی ناشی تمرین می‌باشد و آمینوترانسفراز‌های کبدی، شاخص‌های حساسی برای تعیین آسیب دیدگی سلول‌های کبدی هستند. پژوهش حاضر با مقایسه تأثیر هشت هفته TRX مقاومتی سنتی بر برخی آنزیم‌های (آسپارتات آمینو ترانسفراز آلانین ترانسفراز) در زنان غیرفعال انجام گرفت.روش ­ها: این که به روش نیمه تجربی شد، 28 دختر میانگین سن41/1±07/21 سال شاخص توده بدن 25/4±52/22 کیلوگرم...

Background. The purpose of this study was to compare outcomes of medial patellofemoral ligament (MPFL) repair or reconstruction. Methods. Fourteen knees that underwent MPFL repair and nine (F5, M4) knees that underwent reconstruction at our institution were evaluated for objective and subjective outcomes. The mean age at operation was 20.1 years for repair and 19.8 years for reconstruction. All...

AIMS In 40 patients, we attempted to investigate the efficacy of electromyography-biofeedback (EMG-B) on quadriceps muscle strength after arthroscopic meniscectomy. METHODS The patients were randomly divided into two groups each consisting of 20 subjects. For the control group, a classical exercise program was given (five sessions of EMG-B application for 2 weeks postoperatively). Range of mo...

[Purpose] The aim of this review was to present the available evidence for the effect of McConnell taping on knee biomechanics in individuals with anterior knee pain. [Methods] The PubMed, Medline, Cinahl, SPORTDiscus, PEDro and ScienceDirect electronic databases were searched from inception until September 2014. Experimental research on knee biomechanical or EMG outcomes of McConnell taping co...

This study aimed to examine the effects of closed kinetic chain exercise using electromyography (EMG) biofeedback for selective strengthening of the vastus medialis oblique (VMO) on functional characteristics of lower extremity muscles in patellofemoral pain syndrome (PFPS) patients. The subjects of this study were 30 PFPS patients and they were equally and randomly assigned to a control group ...

Background: The purpose of this study was to investigate the ratio of Electromyography (EM G) activities of the vastus medialis obliqus (VMO) and vastus lateralis (VL) within seven angles of knee joint range of motion using isometric contraction in open kinetic chain (OK C) and closed kinetic chain (CKC). Methods: The dominant knees of 44 healthy female subjects (mean age: 24.84 with range...

OBJECTIVES To evaluate the effects of performing battling rope exercise with and without the addition of whole-body vibration (WBV) on muscle activity of the leg, trunk, and upper body. METHODS Twenty-eight recreationally active university students completed 20-s of battling rope undulation for 6 separate conditions: 1) alternating arm motion no WBV -Alt_NoWBV; 2) alternating arm motion 30 Hz...
