Plyometric training is widely used to improve force production, power and jumping ability through specific muscle action called the stretch shortening cycle (SSC). The SSC involves a powerful concentric contraction preceded by rapid eccentric contraction. The efficacy of the SSC is mainly related to the storage of elastic energy during eccentric contraction and its quick release during concentr...

Objective. Studying the effect of the functional stretching exercise in diplegic children. Design. Children were randomly assigned into two matched groups. Setting. Outpatient Clinic of the Faculty of Physical Therapy, Cairo University. Participants. Thirty ambulant spastic diplegic children, ranging in age from five to eight years, participated in this study. Interventions. The control group r...

BACKGROUND Chronic low back pain is a common problem lacking highly effective treatment options. Small trials suggest that yoga may have benefits for this condition. This trial was designed to determine whether yoga is more effective than conventional stretching exercises or a self-care book for primary care patients with chronic low back pain. METHODS A total of 228 adults with chronic low b...

[Purpose] The purpose of this study was to investigate the effects of two different stretching techniques on range of motion (ROM), muscle activation, and balance. [Subjects] For the present study, 48 adults with hamstring muscle tightness were recruited and randomly divided into three groups: a static stretching group (n=16), a PNF stretching group (n=16), a control group (n=16). [Methods] Bot...

Diabetes complications are the main reasons behind morbidity and mortality preventable by healthy diet and physical activity. There are few studies about the effect of aerobic exercises on insulin resistance in human. Also various training protocols are associated with different results. Since approaches to decrease insulin resistance may be followed by more effectiveness treatment, this study ...

Chondromalacia patellae is a disorder often accompanied by patellofemoral instability. This can be simply a reflex inhibition of the quadriceps muscle secondary to pain. The eccentric and concentric contraction exercises are beneficial in strengthening of the quadriceps muscles and treatment of chondromalacia patellae. This study was conducted to compare between eccentric contraction and concen...

OBJECTIVE To determine the efficacy of neck stabilization exercises in the management of neck pain. PATIENTS AND METHODS Sixty patients with neck pain were randomized to 3 groups, as follows: group 1--physical therapy agents including transcutaneous electrical nerve stimulation, continuous ultrasound and infra-red irradiation; group 2--physical therapy agents + isometric and stretching exerci...

BACKGROUND Approximately 10% of patients with plantar fasciitis have development of persistent and often disabling symptoms. A poor response to treatment may be due, in part, to inappropriate and nonspecific stretching techniques. We hypothesized that patients with chronic plantar fasciitis who are managed with the structure-specific plantar fascia-stretching program for eight weeks have a bett...
