[Purpose] The purpose of this study was to assess the effects of flexi-bar exercises and non-flexi-bar exercises on trunk muscle activity in different postures in healthy adults. [Subjects] Twenty healthy right-hand dominant adults (10 males and 10 females) were selected for this study. None of the participants had experienced any orthopedic problems in the spine or in the upper and lower extre...

Introduction Isometric exercise is a powerful stimulator of the cardiovascular system. Therefore, exercise can be used to unmask subtle cardiovascular changes that are not evident at rest. MRI is a proven method for comprehensive cardiovascular assessment in the resting state. Unfortunately, lack of fast imaging sequences and an appropriate exercise test has prohibited the use of isometric exer...

Aging leads to a decline in strength and an associated loss of independence. The authors examined changes in muscle volume, maximum isometric joint moment, functional strength, and 1-repetition maximum (1RM) after resistance training (RT) in the upper extremity of older adults. They evaluated isometric joint moment and muscle volume as predictors of functional strength. Sixteen healthy older ad...

Purpose: This study aims to investigate the superiority of different exercise modalities, including isotonic and isometric strengthening for quadriceps, over each other their effect on pain, quality life functional capacity in patients diagnosed with chondromalacia patellae (CMP). 
 Methods: was designed as a prospective 30 patients(15 isometric, 15 group) healthy volunteers aged 20–50 yea...

This study sought to examine any differences in upper rectus abdominis (URA) and lower rectus abdominis (LRA) muscle activity during four abdominal exercises, the curl-up, Swiss ball curl-up, Swiss ball jackknife and Swiss ball rollout. Fourteen healthy adults (7 males, 7 females, mean age+/-S.D.=21.8+/-3.8 years) performed abdominal exercises in a randomised order following maximal voluntary i...

Background: Anterior knee pain is the most common problem encountered by clinicians with an estimated prevalence of 15-45% around globe. Thereby, this study aimed to determine effects isometrics and short arc quadriceps exercises on patients patellofemoral pain. Methodology: The quasi-experimental was conducted in Ameen Medical Dental Centre, Karachi a total 80 anterior patients, including both...

CONTEXT Knee extension exercise is an important part of knee rehabilitation. Clinicians prescribe non-weight bearing exercise initially and progress patients to weight bearing exercise once they can perform a straight leg raise (SLR). OBJECTIVE Compare VM activation during a SLR and weight bearing exercises. DESIGN One-way repeated measures design. SETTING University Laboratory. SUBJECT...
