“…20,23–25 In burn patients, aerobic capacity is severely affected and remains below normal values despite significant improvements obtained through aerobic exercise. 5,24,26 According to a recent study, peak VO 2 has a “tendency to plateau or deteriorate” in burned adults.…”

Objectives Exercise programs capable of contributing positively to the long-term rehabilitation of burn patients should be included in outpatient rehabilitation programs. However, the extent and intensity of the resistance and cardiopulmonary exercise prescribed are unclear. This study was conducted to investigate the existence, design, content, and prescription of outpatient cardiopulmonary and resistance exercise programs within outpatient burn rehabilitation. Methods A survey was designed to gather information on existing exercise programs for burn survivors and assess the extent to which they are included in overall outpatient rehabilitation programs. Three hundred and twenty seven surveys were distributed among licensed physical and occupational therapists part of the American Burn Association Physical Therapy/Occupational Therapy Special Interest Group. Results One hundred and three surveys were completed. Eighty-two percent of respondents indicated that their institutions offered outpatient therapy following discharge. The frequency of therapists’ contact with patients during this period varied greatly. Interestingly, 81% of therapists stated that no hospital-based cardiopulmonary endurance exercise programs were available. Patients’ physical function was infrequently determined through the use of cardiopulmonary parameters (oxygen consumption, heart rate) or muscle strength. Instead, more subjective parameters such as range of motion (75%), manual muscle testing (61%), and quality of life (61%) were used. Conclusion Prescription and follow-up assessment of cardiopulmonary endurance training are inconsistent among institutions, underscoring the need for greater awareness of the importance of exercise in any burn rehabilitation program. Identification of cardiopulmonary and progressive resistance parameters for establishing and tracking exercise training is also needed to maximize exercise-induced benefits.

“…We have previously demonstrated that participation in exercise activities has beneficial effects in the rehabilitation of burned children. Improvements in the range of joint movement (4), lean body mass (LBM), muscle strength, aerobic capacity, and average muscle power are seen in burned children after completion of 12 weeks of exercise training (5–7). However, exercise does not reduce metabolic rate in burned children (8).…”

Objectives To investigate whether propranolol administration blocks the benefits induced by exercise training in severely burned children. Study design Children aged 7–18 years (n=58) with burns covering ≥30% of the total body surface area (TBSA) were enrolled in this randomized trial during their acute hospital admission. Twenty-seven patients were randomized to receive propranolol, whilst 31 served as untreated controls. Both groups participated in 12 weeks of in-hospital resistance and aerobic exercise training. Muscle strength, lean body mass, and peak aerobic capacity (VO2 peak) were measured before and after exercise training. Paired and unpaired Student T-tests were used for within and between group comparisons, and Chi-squared tests for nominal data. Results Age, length of hospitalization, and TBSA burned were similar between groups. In both groups, muscle strength, lean body mass, and VO2 peak were significantly greater after exercise training than at baseline. The percent change in VO2 peak was significantly greater in the propranolol group than in the control group (P< 0.05). Conclusions Exercise-induced enhancements in muscle mass, strength, and VO2 peak are not impaired by propranolol. Moreover, propranolol improves the aerobic response to exercise in massively burned children.

“…Measured VO 2 max, as assessed using the Ultima CardiO2 System, was compared with predicted values obtained using the Cooper, Bruce, American College of Sports Medicine (ACSM), and Porro [13] formulas. The Cooper formula was as follows: VO 2 (mL/min) = 43.6 × height (cm) − 4547.1 for males and VO 2 (mL/min) = 22.5 × height (cm) − 1837.8 for females.…”

“…We used this formula since most, if not all of our patients, were unable to run. Porro and coworkers developed a formula for severely burned children at 6 months after discharge from the burn intensive care unit [13]. VO 2 max = 10.33 − 0.62 × age (years) + 1.88 × treadmill time (min) + 2.3 (sex; females = 0, males = 1).…”
