The Use of a Approach to Improve Perceptual Acuity Ability in Male Runners.

We were interested in micro-variations in an athlete's psychophysical state that separate peak exertion from physiological collapse. Thus, we measured perceptual acuity in runners using a classic psychophysical approach, the (JND) on two standard stimuli runs at treadmill speed corresponding to 70%VO and 80%VO. Thirty-four male runners ( age = 35.

Cross-cultural adaptation and concurrent validity of the children's OMNI scale of perceived exertion for Arm-Crank activity in Spina Bifida.

Purpose: To perform a cross-cultural adaptation of the OMNI verbal descriptors to Brazilian-Portuguese and examine the validity of the Brazilian version for arm-crank activity.

Materials And Methods: Cross-cultural adaptation stages were: permission, translation, synthesis, back translation, expert committee review, pretesting, and submission and appraisal. For the concurrent validity, a Brazilian OMNI-Wheel scale was used to obtain rating of perceived exertion for the overall body (RPE) and arms (RPE) in participants ( = 9, 10-17 years) with spina bifida.

Reliability and Validity of a Flume-Based Maximal Oxygen Uptake Swimming Test.

Affective and metabolic responses to self-selected intensity cycle exercise in young men.

Self-selected intensity exercise has resulted in greater affective responses (AR) compared to prescribed exercise of similar intensity and many individuals self-select intensity at a moderate level identified by metabolic analysis. As such, self-selected intensity may be an effective alternative for exercise prescription designed to promote adherence and result in health and fitness benefits. Self-selected intensity has not been well described for many subject populations and exercise modes.

Exercise Prescription Using a Group-Normalized Rating of Perceived Exertion in Adolescents and Adults With Spina Bifida.

Background: People with spina bifida (SB) face personal and environmental barriers to exercise that contribute to physical inactivity, obesity, risk of cardiovascular disease, and poor aerobic fitness. The WHEEL rating of perceived exertion (RPE) Scale was validated in people with SB to monitor exercise intensity. However, the psycho-physiological link between RPE and ventilatory breakpoint (Vpt), the group-normalized perceptual response, has not been determined and would provide a starting point for aerobic exercise in this cohort.

Reliability and Accuracy of a Standardized Shallow Water Running Test to Determine Cardiorespiratory Fitness.

A standardized fitness assessment is critical for the development of an individualized exercise prescription. Although the benefits of aquatic exercise have been well established, there remains the need for a standardized nonswimming protocol to accurately assess cardiorespiratory fitness (CRF) in shallow water. The present investigation was designed to assess (a) the reliability of a standardized shallow water run (SWR) test of CRF and (b) the accuracy of a standardized SWR compared with a land-based treadmill (LTM) test.

Validation of the OMNI Scale of Thermal Sensations.

Concurrent and construct validation of the OMNI Scale of Thermal Sensations was examined in a sample of 16 adult men and 5 adult women. Concurrent validity was established by regressing OMNI ratings of thermal sensation against core and skin temperatures obtained during treadmill walking while wearing firefighter thermal-protective clothing in temperatures between 33 and 35 degrees C. Construct validity was established by regressing the OMNI scale against a construct-specific visual analogue scale.

Energy expenditure, cardiorespiratory, and perceptual responses to shallow-water aquatic exercise in young adult women.

Introduction: Aquatic exercise (AE) is a popular form of physical activity, yet few studies have assessed the individual's energy expenditure (EE) associated with a continuous bout of AE. Studies using indirect calorimetry to measure EE have reported limitations associated with test methodology and the ability to control individual's exercise intensity or tempo.

Purpose: To evaluate EE and cardiorespiratory (CR) responses during a 40-minute shallow-water AE session in young adult women.

Intensity selection and regulation using the OMNI scale of perceived exertion during intermittent exercise.

The purpose of this investigation was to determine if subjects can self-regulate exercise intensity during intermittent exercise by using ratings of perceived exertion. Thirty-one subjects completed an estimation trial maximal treadmill graded exercise test (GXT). Using the oxygen uptake and ratings of perceived exertion (RPE) from the GXT, target RPEs that corresponded to 50% and 70% of oxygen uptake reserve were determined.

Phenotypic spectrum of Simpson-Golabi-Behmel syndrome in a series of 42 cases with a mutation in GPC3 and review of the literature.

Simpson-Golabi-Behmel syndrome (SGBS) is a rare X-linked multiple congenital abnormality/intellectual disability syndrome characterized by pre- and post-natal overgrowth, distinctive craniofacial features, macrocephaly, variable congenital malformations, organomegaly, increased risk of tumor and mild/moderate intellectual deficiency. In 1996, Glypican 3 (GPC3) was identified as the major gene causing SGBS but the mutation detection rate was only 28-70%, suggesting either genetic heterogeneity or that some patients could have alternative diagnoses. This was particularly suggested by some reports of atypical cases with more severe prognoses.

Exercise intensity self-regulation using the OMNI scale in children with cystic fibrosis.

Prescribing exercise at intensities that improve fitness is difficult in children with cystic fibrosis (CF) due to ventilatory limitations and fluctuating health status. Our aim was to determine if children with CF could regulate the intensity of cycle ergometer and treadmill exercise using target ratings of perceived exertion (RPE) derived from the Children's OMNI Scale. We examined prescription congruence (similar oxygen consumption [VO₂] and heart rate [HR] for target RPE) and intensity discrimination (different VO₂ and HR for different RPEs), from cycle to cycle and cycle to treadmill.
