This study evaluated the accuracy of heart rate calibrated from a maximum exercise test for predicting energy expenditure during five activities of daily living (ADL) in participants with spinal cord injury (SCI). Thirteen individuals with SCI underwent maximum exercise testing, followed by portable heart rate and metabolic testing during five ADL. A regression equation was developed from heart...

Research into the physiological and movement demands of Rugby League (RL) referees is limited, with only 1 study in the European Super League (SL). To date, no studies have considered decision making in RL referees. The purpose of this study was to quantify penalty accuracy scores of RL referees and to determine the relationship between penalty accuracy and total distance covered (TD), high-int...

The present study investigated the circadian rhythm variations of heart rate and blood pressure due to 1 (60 minutes) and 2 split exercise sessions (2 × 30 minutes) a day. Fourteen healthy students from the University of Tabriz volunteered to participate in current study. Two groups of subjects in a crossover design were randomly allocated as group I (one session per day, twice a day) and vice ...

Introduction. Heart rate variability (HRV) and the autonomic nervous system are essential indicators of assessing body's functional state. Physical activity obesity, which current problems modern society, affect these indicators, but research on relationship between them is limited.
 Purpose: to determine maximum level physical in obese people preoperative period.
 Materials methods. ...

AIM: This research aimed to study heart rate variability (HRV) in cross-country skiers with different levels of maximal oxygen consumption (VO2max).
 MATERIALS AND METHODS: HRV analysis was carried out using the Ecosan-2007 (Medical Computer Systems, Russia) complex 52 from Komi Republic team (candidates for master sports and Russia). The Oxycon Pro ergospirometric system (Erich Jaeger, Ge...
