Heart rate as a predictor of energy expenditure in people with spinal cord injury (original) (raw)

Energy expenditure and heart rate responses to increased loading in individuals with motor complete spinal cord injury performing body-weight supported exercises

Archives of physical medicine and rehabilitation, 2015

To examine acute metabolic and heart rate responses in individuals with motor complete spinal cord injury. The responses were examined during stepping and standing with body weight support. Cohort Study SETTING: Therapeutic exercise research laboratory PARTICIPANTS: Non-ambulatory individuals with chronic, motor complete, spinal cord injury between T5 and T12 (SCI, N = 8) and healthy, able-bodied controls (AB, N = 8). Not applicable MAIN OUTCOME MEASURES: Oxygen consumption (VO2) and heart rate (HR). Individuals with motor complete SCI performed standing and stepping exercises in a body weight support (BWS) system with manual assistance of lower body kinematics. Oxygen consumption (VO2) and heart rate (HR) responses were assessed in relation to level of body weight support. Weight support was provided by an overhead lift at high (≥50% BWS) or low (20-35% BWS) levels during stepping and standing. Although participants with motor complete SCI were unable to stand or step without assis...

The energy expenditure of people with spinal cord injury whilst walking compared to an able-bodied population

South African Journal of Physiotherapy, 2016

Background: In the field of spinal cord injury (SCI) research there is an emphasis on the ability to ambulate.Purpose: To determine the ambulation energy expenditure (EE) and factors that affect ambulation EE in SCI participants compared to able-bodied participants.Methods: This was a cross-sectional study. Participants were recruited from seven SCI rehabilitation units within the Johannesburg area. The following were used: demographic questionnaire to capture participants’ characteristics, modified Ashworth scale for spasticity; goniometer for range of movement (ROM); American Spinal Injury Association (ASIA) scale for patient classification; accelerometer for EE and the six-minute walk test (6MWT) for endurance. Characteristics of the study participants were summarised using descriptive statistics. Data were analysed as follows: two-sample t-test for comparison between the able-bodied and SCI sample and Pearson product moment correlations for relationship between identified factor...

Physiological and lipid profile response to acute exercise at different intensities in individuals with spinal cord injury

Spinal cord series and cases, 2017

Experimental and cross-sectional study. To assess the immediate effect of exercise on heart rate (HR), oxygen uptake (VO2), pulmonary ventilation (PV), oxygen pulse (OP), glucose and lipids of wheelchair basketball players with spinal cord injury (SCI). Center of Studies in Psychobiology and Exercise-São Paulo, Brazil. In all, nine wheelchair basketball players with SCI and nine able-bodied controls (C) performed three exercise sessions at different intensities: ventilatory threshold 1 (VT1), 15% below VT1 and 15% above VT1 with a duration of ~24-34 min. HR, VO2, PV, OP, glucose and lipids were analyzed. VO2, PV and OP were significantly lower in the players with SCI compared to C during the same intensity exercise sessions. However, the individuals with SCIs demonstrated increases in HR, PV and OP at similar rates to C. Triglycerides of the SCI group were elevated 30 min after the exercise session at VT1 compared to values before the exercise session (P=0.017); this elevation was n...

Energy expenditure after spinal cord injury in people with motor-complete tetraplegia or motor-complete paraplegia

Spinal cord, 2018

Cross-sectional. This study aimed to describe and compare VO and energy expenditure at rest (REE) and during standardized sedentary, non-exercise physical activity, and exercise activities, in people with motor-complete tetraplegia (C5-C8). Further, REE and energy expenditure (EE) for the different activities were compared to data from a reference group of people with motor-complete paraplegia (T7-T12). Sweden. The sample of people with motor-complete tetraplegia consisted of 26 adults (seven women) with SCI, C5-C8 AIS A-B. REE and EE for the different activities were measured with indirect calorimetry. The results were further compared to people with motor-complete paraplegia. Resting VO was 2.57 ml O kg min, 2.54 for men and 2.60 for women. The VO or activity energy expenditure related to body weight increased three to four times during non-exercise physical activity compared to sedentary activities for the people with motor-complete tetraplegia, and up to six times during exercis...
