The diagnostic characteristics for exercise-test outcome were calculated with the software WINPEPI, version 11.26 [ 34].
The same group performed a meta-regression on trials of exercise for CNSLBP in an attempt to determine the characteristics of exercise that may optimise outcome from this intervention [ 21].
Whether there are characteristics of exercise other than the time course of post-exercise soreness that are different in laboratory and natural sports settings is for other researchers to determine.
Lastly, residency characteristics; lack of time for exercise, leisure activities, and health-promoting behaviors; and perceptions surrounding support from residency personnel (e.g., house staff peers, administrative personnel, faculty) may also have played a role in residents' health ratings.
Characteristics of the exercise programs for each group from each study are described in Table 1.
In contrast, Ito et al observed a significant improvement in HRV characteristics following 8 weeks of exercise training in mildly obese younger women (45.9±4 y; [38]) In the only study we are aware of using a longer exercise training intervention, Stein et al observed an improvement in HRV characteristics for older women (66±4 y) exercising at 70% of VO2max (∼80 85% HRmax).
The baseline characteristics for both the control and exercise groups are listed in Table 1.
Initial physical characteristics of the exercise and control groups are shown in Tables 1 and 2. For prior exercise, three studies reported that none of the participants were exercising regularly prior to enrollment [ 62, 68, 71], one reported that some were exercising regularly [ 69], while another reported that participants exceeded the guidelines for physical activity at baseline [ 70].
Receiver-operating-characteristic curves identified as best predictors ELVI reserve for exercise (AUC = 0.871) and dobutamine (AUC = 0.848) and VAC reserve (AUC = 0.696) for dipyridamole.
This not only offers a limited diet in terms of nutrition, but starves the animals of needing to exercise their innate characteristics for seeking out food in the landscape.
The characteristics of the exercise interventions varied across treatment areas.
