BACKGROUND Postural control allows performance of daily and sports activities. The previous studies show that postural sway inceases in orthopaedic injuries such as osteoarthritis and total knee arthroplasty. OBJECTIVE To compare postural sway, risk of falling and function between individuals with and without patellofemoral pain syndrome (PFS). METHODS This study included 22 subjects with p...

There has been some evidence that extremes of CO2 sensitivity can indicate an individual's potential for sprint or endurance athletic performance. This study examined the responses to CO2 rebreathing, and previously validated sprint and endurance tests by subjects who were involved in regular, but not intensive, swimming training. The aim was to determine whether subjects with low CO2 sensitivi...

Introduction Endurance of the back muscles is considered as an important contributing factor in the development of low back pain. Currently, researchers are looking at reliable methods for measuring the back muscle’s fatigue rate by surface electromyogram (EMG). Many of these studies are still at the experimental stage and the feasibility of using EMG as a clinical tool for such purpose remains...

[Purpose] This study investigated the effects of inclined treadmill walking on pelvic anterior tilt angle, hamstring muscle length, and back muscle endurance of seated workers with flat-back syndrome. [Subjects] Eight seated workers with flat-back syndrome who complained of low-back pain in the L3-5 region participated in this study. [Methods] The subjects performed a walking exercise on a 30° ...

OBJECTIVES To evaluate the utility of our newly devised method (incremental stand-up exercise-load) to determine features of general endurance in hemiplegic patients. SUBJECTS/PATIENTS Participants were 15 healthy adults and 15 hemiplegics, with 13 men and 2 women in each group. METHODS To evaluate endurance, the subjects were required to assume a sitting position on a bed for 3 minutes and...

Introduction: Studies have shown that insufficient recovery between sessions causes immune suppression. The aim of this study was to investigate the effect of repeated bouts resistance and endurance exercise on blood leukocytes, lymphocytes, neutrophils, monocytes count and plasma cortisol levels in athlete girls. Materials and methods: 9 athlete girls (ages, 20-25 years), participated i...
