Background The emergence of mHealth and the utilization of smartphones in physical activity interventions warrant a closer examination of validity evidence for such technology. This study examined the validity of the Samsung S Health application in measuring steps and energy expenditure. Methods Twenty-nine participants (mean age 21.69 ± 1.63) participated in the study. Participants carried a Samsung smartphone in their non-dominant hand and right pocket while walking around a 200-meter track… 

Figures and Tables from this paper

Accuracy of “S Health” pedometer application during walking and stair climbing
Assessing the accuracy of step-counting with different smartphones using the S Health step counting application at long and short walking distances, and stair climbing suggests that accuracy of smart-phones increase with increased number of steps and correspond to newer models.
Validity of the “Samsung Health” application to measure steps: A study with two different samsung smartphones
Results indicated that the validity of Samsung Health varied depending on the smartphone model, its body location, and the type of gait (walking and running).
An investigation into the validity and reliability of mHealth devices for counting steps in chronic stroke survivors
Objective: To investigate the validity and test–retest reliability of mHealth devices (Google Fit, Health, STEPZ, Pacer, and Fitbit Ultra) to estimate the number of steps in individuals after chronic
Effect of a Home-Based Mobile Health App Intervention on Physical Activity Levels in Patients With Heart Failure: A Randomized Controlled Trial.
Repeated-measures analysis of variance showed a significant group-by-time interaction, indicating that the intervention group had a greater improvement in physical activity levels, symptom burden, and health-related quality of life than the usual care group.
Recommendations for determining the validity of consumer wearable and smartphone step count: expert statement and checklist of the INTERLIVE network
The INTERLIVE consortium recommends that the proposed protocol is used when considering the validation of any consumer wearable or smartphone step counter, highlighting the imminent need for the development of feasible alternative ‘gold-standard’ criterion measures for free-living validation.
Recommendations for Determining the Validity of Consumer Wearables and Smartphones for the Estimation of Energy Expenditure: Expert Statement and Checklist of the INTERLIVE Network
Consumer wearables and smartphone devices commonly offer an estimate of energy expenditure (EE) to assist in the objective monitoring of physical activity to the general population. Alongside
To find out and evaluate the calorie intake of a bicycle ergometer and various mobile apps under different physical loads, it was found that the lowest load difference was for all apps, the least difference wasfor the POLAR app and the highest was for the SAMSUNG app.
Factors associated with validity of consumer-oriented wearable physical activity trackers: a meta-analysis
Moderator analyses revealed that the brand, placement of the device, and population significantly impact the magnitude of the validity evidence, while the type of activity and release year of the devices do not.


Validity of the Actical activity monitor for assessing steps and energy expenditure during walking
There was no statistical difference between Actical steps and actual steps in self-selected pace walking and during treadmill walking at moderate and fast speeds, and the Actical underestimates EE of walking at constants speeds ≥1.38 m · s–1.
Validity of the Apple iPhone® /iPod Touch® as an accelerometer-based physical activity monitor: a proof-of-concept study.
The results suggest that an iPhone/iPod Touch can predict aspects of locomotion with accuracy similar to other accelerometer-based tools and future studies may leverage this and the additional features of smartphones to improve data collection and compliance.
Evaluation of the Accuracy of a Triaxial Accelerometer Embedded into a Cell Phone Platform for Measuring Physical Activity.
This work wrote a software application to access the on board accelerometer from the iPhone to measure and quantify physical activity to assess physical activity in a controlled laboratory setting.
Effects of body mass index on step count accuracy of physical activity monitors.
The data suggest that BMI does not greatly affect the step-counting accuracy of accelerometer-based activity monitors, however, the accuracy of the ActiGraph, ActiCal, and NL-2000 decreases at slower speeds.
Use of pedometers and accelerometers in clinical populations: validity and reliability issues
Pedometers and accelerometers are useful for tracking ambulatory physical activity in clinical populations, and those that display steps and/or calories are useful in motivating patients to increase their activity levels.
Validity of the Omron HJ-112 pedometer during treadmill walking.
The Omron HJ-112 pedometer validly assesses steps in different BMI groups during constant- and variable-speed walking; other than that in the pants pocket, placement of the pedometer has little effect on validity.
Evaluation of activity monitors in controlled and free-living environments.
It is demonstrated that BMI does not affect the step output of commonly used activity monitors during walking and 67 m·min⁻¹ seems to be the minimum speed required for accurate step counting, at least for most waist-mounted activity monitors.
Is there a valid app for that? Validity of a free pedometer iPhone application.
The IP application was not accurate in counting steps and recorded significantly lower step counts than the SW and TC, thus, the free pedometer application used is not a valid instrument for monitoring activity during treadmill walking.
Step activity monitor: Increased accuracy in quantifying ambulatory activity
The accuracy and additional capabilities, including a real‐time memory record of activity, of the step activity monitor make it well suited for objectively quantifying ambulatory activity, especially for obese subjects.
Walking and measurement.
The articles presented at the conference on "Walking for Health: Measurement and Research Issues and Challenges" suggest future research directions that will increase the knowledge of walking and health outcomes and provide new approaches to get people walking.
