The aim of this study was to examine physical, physiological, and motor responses and perceived exertion during different soccer drills. In small-sided games, the individual playing area (∼ 275 m², ∼ 175 m², and ∼ 75 m²) was varied while the number of players per team was kept constant: 5 vs. 5 plus goalkeepers. Participants were ten male youth soccer players. Each session comprised three small...

PURPOSE To describe the objective and subjective match load (ML) of wheelchair basketball (WB) and determine the relationship between session heart-rate (HR) -based ML and rating-of-perceived-exertion (RPE) -based ML methods. METHODS HR-based measurements of ML included Edwards ML and Stagno training impulses (TRIMPMOD), while RPE-based ML measurements included respiratory (sRPEres) and muscu...

The purpose of this study was to determine whether heart rate and ventilation can be predicted from WE. Also, this study determined whether breathing or heart rate sensations caused perceived effort or strain (degree of perceived central strain). Eight ambulatory active teenagers (ages 13-16 years, M= 14.75) with spastic cerebral palsy performed a discontinuous maximum bicycle ergometer protoco...

OBJECTIVE To examine the relationship between psychologic cues of somatic stress and physiologic responses to exercise in persons with paraplegia and tetraplegia. DESIGN Repeated measures with 2 comparison groups. SETTING Academic medical center. PARTICIPANTS Forty-two subjects between 18 and 69 years of age with motor-complete spinal cord injury (SCI) resulting in paraplegia or tetrapleg...

The aim of this study was to investigate the physiological responses to moderate-intensity continuous and high-intensity intermittent exercise. Twelve physically active male subjects were recruited and completed a 5-km run on a treadmill in two experimental sessions in randomized order: continuously (70% sVO2max) and intermittently (1:1 min at sVO2max). Oxygen uptake, excess post-exercise oxyge...

BACKGROUND Since hypohydration commonly occurs in sports, studies on anaerobic exercise performance under this condition have been extensively carried out. When describing anaerobic performance, authors usually refer to a drop in anaerobic performance as fatigue index (FI) which is conventionally calculated using peak and low power data points. Meanwhile, another possible method in explaining a...

abstractthe borg rating of perceived exertion (rpe) is a way of measuring physicalactivity intensity level. purpose of this study is evaluation of validity and reliability the rpe scale (persian version) based on heart rate variability in students of isfahan university of medicalsciences.methods: an interventional study conducted  on 10 male students, heart rate (hr) and rpe  in two 0-10 and 6-...
