BACKGROUND The aim of the present study was to compare the changes in voluntary strength (isometric, concentric, and eccentric) and functional mobility in response to maximal isokinetic eccentric-only resistance training to those elicited by maximal isometric-only or maximal isokinetic concentric-only resistance training in older adults. METHODS Twelve women (73 +/- 7 years) and 18 men (73 +/...
Background:Childhood overweight and obesity, which are considered as global epidemic, can be assessed using Body Mass Index (BMI). BMI difference can lead to anatomic changes due to an increased body load. This increase might also affect motor performance, including changes in postural balance and muscle strength. Aims and Objectives: to explain the influence of BMI on postural balance and lowe...
Aim: The purpose of this study is to evaluate the intra-rater reliability of measuring isometric strength of shoulder muscles in healthy subjects and patients with neck pain. Methods: a total of 12 healthy subjects (mean age, 28.08 ± 4.35 years) and 12 patients with neck pain (mean age, 29.45 ± 5.46 years) voluntarily participated in the present study. Participants sat on a custom-made chair w...
We evaluated the relationship between altered foot function and knee osteoarthritis through a specific comparison of toe grip strength in older women with and without knee osteoarthritis. Participants were 120 women with knee osteoarthritis (OA group) and 108 healthy community-dwelling women with no history of knee pain and lower limb surgery (control group). The following factors and outcome v...
The relationship between muscle length, integrated electromyographic activity, and torque of the biceps femoris muscle was investigated while the line of action of the muscle at the knee was held constant. Muscle length was changed by varying the hip joint angle. Sixteen subjects produced 1) maximal isometric contractions, 2) contractions with constant submaximal torque, and 3) contractions wit...
A comparison of assisted and unassisted proprioceptive neuromuscular facilitation techniques and static stretching. J Strength Cond Res 26(5): 1238-1244, 2012-Proprioceptive neuromuscular facilitation (PNF) stretching often requires a partner. Straps are available allowing an individual to perform PNF stretching alone. It is not known if a strap provides similar improvements in the range of mot...
The purpose of this investigation was to determine if training isometrically with electrical stimulation (ES) alone would significantly increase isometric strength of the quadriceps femoris muscle. The relationships between the strength changes and the relative force and duration of training contractions were also studied. An experimental group (Group 1) and a control group (Group 2), 12 subjec...
Background :Many studies have reported the increase in strength of the untrained contralateral limb after unilateral training. The aim of this study was to compare the cross education effect in the young and elderly persons. Methods : In this quasi-experimental and pre-post study, 12 young people aged 28.25 ±3.11 years and 12 elderly persons (aged 73.08 ± 5.3 years) participated. The subjec...
Aims and background: Rheumatoid arthritis is an inflammatory, autoimmune, chronic, and progressive connective tissue disease with an unknown cause that is associated with symptoms such as pain, swelling, tenderness, stiffness, and dryness in the joints and decreased energy, leading to muscle inactivity and atrophy. The aim of this study was to investigate the effect of Pilates exercises on ...
