“…The assessment of footground contact times (Tharion et al, 2004) constitutes another technique that provides an estimate of speed and, hence, distance. It is interesting to note that recent studies (Ayabe et al, 2008a;Marshall et al, 2009) have indicated the potential application of step counting to estimate PAEE or the level of PA intensity. When the simple index (steps) is transformed to the stepping rate (steps per minute), which is determined with a short epoch (a high-frequency sampling interval), it is therefore considered to be a useful index for assessing moderate to vigorous intensity PA in free-living conditions.…”

Are pedometers adequate instruments for assessing energy expenditure?

Objective: Assessing energy expenditure (EE) is important for the control of obesity. Daily step counts have become popular and constitute one practical technique for evaluating the physical activity (PA) in large population studies. However, information on the capacity of pedometers to track EE in free-living conditions remains scanty. Subjects and methods: The 24-h EE of 71 healthy adults was measured by indirect calorimetry in a large respiratory chamber. Two accelerometers were attached to the waist, one for counting the total daily steps (ACC STEP ) and another for measuring the anteroposterior whole body acceleration calculated as the root mean square of the acceleration signal at every second (ACC RMS ). Results: The ACC STEP was not associated with PA-related EE (PAEE) or 24-h EE. Body weight (BW) was the main determinant of both the values (explaining 30 and 75% of the variance, respectively). Approximately 8% (Po0.001) of the variance in PAEE was attributed to the ACC RMS after BW was accounted for, whereas the ACC STEP did not explain any additional variance. A multiple stepwise regression analysis revealed that BW, height and ACC RMS were highly significant determinants of 24-h EE and accounted for as much as 83% of the total variance. Conclusions: Recording the number of steps per day does not provide accurate information on EE, and at best is only a crude predictor of the general PA in terms of displacement. In contrast, accelerometry signals are considered to be a more meaningful factor in the assessment of EE rather than step counts under sedentary conditions.

“…This brings a challenging problem, as health profits are related to the intensity of activity. [12] Although current pedometers do not, is it possible to translate current recommendations for the intensity of physical activity into a pedometerbased exercise? [12] Our new pedometer records timestamped step goals range, unlike simple pedometers.…”

“…[11][12][13] However, the intensity of exercise is affected by the aerobic capacity of each individual. Therefore, the intensity should be managed individually in exercise prescription for physical activity.…”

Objectives:The aim of this study was to investigate the effectiveness of walking with Equipment for Clever Exercise (ECE PEDO) compared to supervised, moderate-intensity, aerobic, treadmill walking exercise in overweight and obese women. Patients and methods:Between September 2014 and January 2015, 28 women with overweight and obesity were assigned to two groups: supervised treadmill walking (Group 1, n=14) or walking with ECE PEDO (Group 2, n=14). The target heart rate (HR) corresponding to values of 50 to 70% VO 2 max were determined by submaximal treadmill test. Group 1 was instructed walking at their target HR on treadmill. The number of steps in a min corresponding to the target HR was calculated by a criterion pedometer and Group 2 was instructed walking in this step range recorded to the ECE PEDO giving audible feedback. Before and after a 12-week exercise program, all participants were evaluated by Body Mass Index (BMI) and waist circumference (WC). Ultrasonographic visceral fat thickness (VFT) and ergospirometric VO 2 max. Results:The VFT decreased in both walking groups in association with reduced WC and weight loss and also significant increases in the VO 2 max after exercise intervention (p<0.05). The VFT decreased only in women by walking with ECE PEDO compared to the other group (p<0.05). Conclusion:Our study results showed that both moderate-intensity exercise provided by a novel pedometer and supervised treadmill walking showed significant improvements in abdominal obesity and VO 2 max.

“…With particular reference to intensity-based steps, recently documented literature on intensity-based steps/day [18,19] suggests a minimum of 100 steps/minute to be a reliable estimate of, and target for, moderateintensity physical activity (aerobic steps). Current literature also suggests that the accumulation of moderate-intensity physical activity in bouts of at least 10 minutes is acceptable in contributing towards meeting current physical activity guidelines.…”

“…This allowed us to determine step/minute rates, so as to closely relate to moderate-intensity physical activity and current guidelines. [17][18][19] This application is also a novel application in pedometer-based research and provides an opportunity for further application and modification.…”

Background.The association between self-perceived and actual physical activity, with particular reference to physical activity guidelines, may be an important factor in determining the extent of uptake of and compliance with physical activity. Objectives. To examine the association between self-perceived and actual physical activity in relation to physical activity guidelines, with reference to volume, intensity and duration of steps/day, and to establish the level of agreement between pedometer-measured and selfreported ambulatory physical activity, in relation to current guidelines. Methods. A convenience sample of adults (N=312; mean (standard deviation) age 37 (9) years), wore a pedometer (minimum 3 consecutive days) and completed a questionnaire that included information on physical activity patterns. Analyses of covariance, adjusted for age and gender, compared volume-and intensity-based steps according to meeting/not meeting guidelines (self-reported). The extent of agreement between self-reported and pedometer-measured physical activity was also determined. Results. Average (SD) steps/day were 6 574 (3 541). Of a total of 312 participants' self-reported data, those meeting guidelines (n=63) accumulated significantly more steps/day than those not meeting guidelines (8 753 (4 251) v. 6 022 (3 114) total steps/day and 1 772 (2 020) v. 421 (1 140) aerobic steps/day, respectively; p<0.0001). More than half of the group who self-reported meeting the guidelines did not meet guidelines as per pedometer data. Conclusion. The use of pedometers as an alternative and/or adjunct to self-reported measures is an area for consideration. Steps/day recommendations that consider intensity-based steps may provide significant effects in improving fitness and health.S Afr J SM 2014;26(3):77-81.
