'My sweat my health': Real time sweat analysis using wearable micro-fluidic devices
(2011)
Curto, Vincenzo F.; Angelov, Nikolay; Coyle, Shirley; Byrne, Robert; Hughes, Sarah; Moyna, Niall; Diamond, Dermot; Benito-Lopez, Fernando
Abstract:
In this work a robust, non-invasive and wearable micro-fluidic system was developed and employed to analyse pH of sweat in real time during exercise. The device is incorporated in an optical detection platform designed to provide real-time information on sweat composition. The device has been tested by monitoring the pH of sweat during 55 minutes of cycling activity. During these trials, the data obtained by the micro-fluidic system was compared to pH measurements obtained in parallel studies with a conventional electrochemical sensor.

Abstract:
Background: MedEx Wellness is a community-based chronic illness rehabilitation programme located at Dublin City University. It offers exercise classes in a medically supervised environment to patients with a range of chronic illnesses. MedEx ‘Move On’ is the oncology rehabilitation programme that caters for cancer survivors. This study aimed to determine the effect of ‘Move On’ on cancer survivors’ physical and psychological wellbeing. Methods: Adults with an established diagnosis of cancer, who have completed their adjunctive therapy, are referred to ‘Move On’. Participants attend two 60 minute supervised exercise classes per week for 12 weeks. Recruitment to the ‘Move On’ programme occurs every 12 weeks, with approximately 30 participants attending per cycle. Classes are led by exercise specialists and involve a combination of aerobic and resistance training. A single arm pre-test, post-test design was used. At baseline and week 12, assessments of cardiorespiratory fitness (10m sh...

Abstract:
Background: Physical activity is a principal intervention in primary and secondary prevention of chronic illness. While the benefits of community based rehabilitation is acknowledged,the rate of attendance and adherence remains sub optimal. Self-efficacy is acknowledged to be a key factor relating to adherence in rehabilitation but the construct of proxy efficacy, defined as one’s confidence in the skills and abilities of a third party to function effectively on another’s behalf, is less often studied. This paper examines the relationship between gender and ‘self’ and ‘proxy-efficacy’ and their potential role in attendance to a community based chronic illness rehabiliation (CBCIR) programme. Methods: Participants attending induction at the programme completed a questionnaire assessing demographics and both self (9 items) and proxy efficacy for exercise (9 items) which was assessed on a Likert scale from 0 (not confident at all) to 10 (very confident), with a higher score indicating ...

Abstract:
In this paper we describe our work on creating a multi-modal sensing platform for providing feedback to tennis coaches and players. The platform includes a fixed installation around a tennis court consisting of a video camera network and a localisation system as well as wearable sensing technology deployed to individual athletes. We describe the various components of this platform and explain how we can capture synchronised multi-modal sensor data streams for games or training sessions. We then describe the content-based retrieval system we are building to facilitate the development of novel coaching tools. We provide some examples of the queries that the system can support, where these queries are chosen to be suitably expressive so as to reflect a coach's complex information needs regarding tennis-related performance factors.

Abstract:
We report a new method for the real-time quantitative analysis of sodium in human sweat, consolidating sweat collection and analysis in a single, integrated, wearable platform. This temporal data opens up new possibilities in the study of human physiology, broadly applicable from assessing high performance athletes to monitoring Cystic Fibrosis (CF) sufferers. Our compact Sodium Sensor Belt (SSB) consists of a sodium selective Ion Selective Electrode (ISE) integrated into a platform that can be interfaced with the human body during exercise. No skin cleaning regime or sweat storage technology is required as the sweat is continually wicked from the skin to a sensing surface and from there to a storage area via a fabric pump. Our results suggest that after an initial equilibration period, a steady-state sodium plateau concentration was reached. Atomic Absorption Spectroscopy (AAS) was used as a reference method, and this has confirmed the accuracy of the new continuous monitoring appr...

Abstract:
The objectives of this study were to; quantify positional differences in the activity profiles of Gaelic football players and to evaluate decrements in physical performance during a pre-season competition. Global positioning system (GPS) data was recorded from 36 players from 3 teams across 5 games. The relative distance covered in locomotor activities, peak speed, relative PlayerLoad™ (PL.min-1) and heart rate responses were evaluated between playing positions and across match periods using a mixed model analysis. The mean relative distance of 92.4 ± 23.3 m.min-1 covered, comprised 28.4 ± 10.2 m.min-1 of high intensity running (m.min-1 ≥ 4.0 m.s-1) and 9.9 ± 3.9 m.min-1 of very high intensity running (m.min-1 ≥ 5.5 m.s-1). High intensity running and relative PlayerLoad™ (PL.min-1) was significantly higher in half-backs, midfielders and half-forwards compared to the full-backs, whereas only the half-backs and half-forwards displayed significantly greater values compared to full-forw...

Abstract:
Real time monitoring of the wellness of sportspersons, during their sporting activity and training, is important in order to maximise performance during the sporting event itself and during training, as well as being important for the health of the sportsperson overall. We have combined a suite of common, off-the-shelf sensors with specialist body sensing technology we are developing ourselves and constructed a software system for recording, analysing and presenting sensed data gathered from a single player during a sporting activity, a football match. We gather readings for heart rate, galvanic skin response, motion, heat flux, respiration, and location (GPS) using on-body sensors, while simultaneously tracking player activity using a combination of a playercam video and pitch-wide video recording. We have aggregated all this sensed data into a single overview of player performance and activity which can be reviewed, post-event. We are currently working on integrating other non-inv...

Abstract:
Differences in performance between winning and losing were examined in 1 elite Gaelic football team in 20 games across 2 complete competitive seasons. Possession was codified using Dartfish TeamPro software and distance covered; walking, jogging, running, and running at high and maximum speeds, was evaluated using Catapult Optimeye S5 player tracking devices. Distance covered in low intensity activity (LIA, ˂4.0 m.s-1 ), high intensity running (HIR, ≥4.0 m·s-1 ) and very high intensity running (VHIR, ≥5.5 m·s-1 ) was also examined along with PlayerLoad™, which represented a composite of all accelerations. Data from 53 players (n=405 files) was collated into specific match periods to facilitate a temporal analysis between the first and second halves and from quarter 1 (Q1) to quarter 4 (Q4), with significance accepted at p ≤ 0.05. Total distance and running was higher in games lost, whereas total distance, walking and LIA was higher in halves lost. Only walking was higher in quarters...

Abstract:
There are many projects today where data is collected automatically to provide input for various data mining algorithms. A problem with freshly generated datasets is their unsupervised nature, leading to difficulty in fitting predictive algorithms without substantial manual effort. One of the first steps in dataset preparation and mining is anomaly detection, where clear anomalies and outliers as well as events or changes in the pattern of the data are identified as a precursor to subsequent steps in data mining. In the research presented here, we provide a multi-step anomaly detection process which utilises different combinations of algorithms for the most accurate identification of outliers and events.

Association of objectively measured physical activity with vascular endothelial function in male adolescents
(2015)
Sheridan, Sinead; Moyna, Niall
Abstract:
Purpose: Cardiovascular disease (CVD) begins in childhood primarily due to exposure to lifestyle-mediated risk factors such as inactivity and low cardiorespiratory fitness (CRF). Endothelial dysfunction is one of the earliest events in the development of CVD. Self-reported light intensity physical activity (LIPA) is positively associated with endothelial function (EF) in adolescents. The purpose of this study was to examine the relation between objectively measured physical activity (PA) and EF in healthy male adolescents. Methods: Low (n=8, VO2max = 40.4 ± 2.3 mL.kg1.min-1), moderate CRF (n=12,VO2max = 54.6 ± 3.9 mL.kg1.min-1) and high CRF (n=15, VO2max = 63.7 ± 4.0 mL.kg1.min-1) healthy males (mean age 15.77 ± 0.4; yr) participated in the study. High-resolution ultrasonography was used to assess endothelial dependent (EDD) in response to brachial artery flow mediated dilation. Participants wore a tri-axial ActivPAL accelerometer for 6 days. Total time spent in sitting, st...

Abstract:
Textile-based sensors offer an unobtrusive method of continually monitoring physiological parameters during daily activities. Chemical analysis of body fluids, noninvasively, is a novel and exciting area of personalized wearable healthcare systems. BIOTEX was an EU-funded project that aimed to develop textile sensors to measure physiological parameters and the chemical composition of body fluids, with a particular interest in sweat. A wearable sensing system has been developed that integrates a textile-based fluid handling system for sample collection and transport with a number of sensors including sodium, conductivity, and pH sensors. Sensors for sweat rate, ECG, respiration, and blood oxygenation were also developed. For the first time, it has been possible to monitor a number of physiological parameters together with sweat composition in real time. This has been carried out via a network of wearable sensors distributed around the body of a subject user. This has huge implicati...

Abstract:
CVD refers to disease of the heart and blood vessels and is the leading cause of mortality in Ireland. CVD Begins in childhood and adolescence due primarily to exposure to lifestyle mediated risk factors . Endothelail dysfunction, induced by CVD risk factors, is one of the earliest events in the development of CVD and precedes structural changes in the artery walll such as intima media thickness. Exercise training has been shown to restrore endothelial function (EF), decrease carotid intima media thickness (cIMT) and improve CV risk profile in obese children. There is currently no research that has examined subclinical atherosclerotic CVD in asympomatic adolescents with low and high cardiorepsiratory fitness (CRF). This study compared CVD risk factors, cIMT and EF in adolescent boys with low and high CRF and examined the relation between CRF and cIMT and CRF and FMD in asympomatic adolescent boys. It was hypothesised that boys with a high CRF would have a healthier CV profile and th...

Cardiorespiratory fitness, oxygen uptake efficency slope and endothelial function in male adolescents
(2015)
Sheridan, Sinead; O'Connor, Paul L.; Sheridan, Dermot; Moyna, Niall
Abstract:
Cardiorespiratory fitness (CRF) is a independent risk factor for CVD and all-cause mortality. Maximal oxygen uptake (VO2max), is considered the gold standard measurement of CRF. Due to its effort dependency, a true plateau in VO2 during incremental exercise is often not attained, particularly in overweight and obese pediatric populations 1. The oxygen uptake efficiency slope (OUES) has been proposed as an objective and effort independent submaximal measure of cardiopulmonary reserve. Studies in healthy and obese children have reported a strong positive relation between OUES and VO2max. Children with high CRF have higher OUES values than those with low CRF 2. Furthermore, improvements in CRF following exercise training, are associated with restoration of endothelial function (EF) in obese children 3. The purpose of this study was to examine the relation between OUES, VO2max and EF in healthy male adolescents. ado

Abstract:
High volume endurance training (ET) has traditionally been used to improve aerobic capacity but is extremely time-consuming in contrast to low-volume short-duration sprint interval training (SIT) that improves maximal oxygen uptake (V_ O2max) to a similar extent. Few studies have compared the effects of SIT vs. ET using running-based protocols, or in team sport athletes. Club level male Gaelic football players were randomly assigned to SIT (n = 7; 21.6 6 2.1 years) or ET (n = 8; 21.9 6 3.5 years) for 6 sessions over 2 weeks. V_ O2max, muscle mitochondrial enzyme activity, running economy (RE), and high-intensity endurance capacity (HEC) were measured before and after training. An increase in V_ O2max (p # 0.05) after 2 weeks of both SIT and ET was observed. Performance in HEC increased by 31.0 and 17.2% after SIT and ET, respectively (p # 0.05). Running economy assessed at 8, 9, 10, and 11 km$h 21 , lactate threshold and vV_ O2max were unchanged after both SIT and ET. Maximal activi...

Abstract:
Purpose: Wrist-worn monitors are developed to unobtrusively measure heart rate (HR) at rest and during exercise. assessed the concurrent validity and reliability of the Microsoft Band 2 (Microsoft-Band2) and Fitbit Charge HR (Fitbit) to measure HR at rest and during exercise. Methods: Healthy men (n=12) and women (n=12) (mean (± SD); age 24.3 ± 3.1 yr) were tested on two occasions separated by at least 7 d. The same protocol was used during each visit and consisted of 3-min conditions in the following order - supine, sitting, 6 km.h-1 walk, 10 km.h-1 run, and 12.km.h-1 run. HR was continuously measured using a Holter monitor, Microsoft-Band2, and Fitbit, and averaged across each 3-min condition. A Bland Altman analysis was conducted to calculate the intervals of agreement (95%). A 2 tailed t-test at α = 0.05 was also used to compare the mean differences in measurements with the Holter for both devices and an F-test (α = 0.05) was used to compare the measurement dispersion characteri...

Abstract:
Sensor technology has been exploited in many application areas ranging from climate monitoring, to traffic management, and healthcare. The role of these sensors is to monitor human beings, the environment or instrumentation and provide continuous streams of information regarding their status or well being. In the case study presented in this work, the network is provided by football teams with sensors generating continuous heart rate values during a number of different sporting activities. In wireless networks such as these, the requirement is for methods of data management and transformation in order to present data in a format suited to high level queries. In effect, what is required is a traditional database-style query interface where domain experts can continue to probe for the answers required in more specialised environments. The challenge arises from the gap that emerges between the low level sensor output and the high level user requirements of the domain experts. This pape...

Abstract:
Background: Physiologically based exercise prescriptions normally involve identifying an intensity range that elicits a predetermined VO2 or heart rate. In many instances prescribed exercise that exceeds an individual’s preferred level of intensity may establish a negative attitude toward physical activity. Longitudinal studies report that participants tend to deviate from physiologically based prescribed levels of intensity in favour of their apparently preferred levels. Self-regulated exercise intensity may increase enjoyment and promote adherence by allowing individuals successfully complete an activity within their perceptual preference range and without undue physiological strain. The purpose of this study is to examine the effect of self-regulated exercise intensity on endothelial function (a validated surrogate measure of early atherosclerosis) in men with coronary artery disease. Methods: Eight men with coronary artery disease (65.7 ± 4.5 yr, VO2max 18.6 ± 4.1 ml/kg/min...

Abstract:
Personal Health (pHealth) sensor networks are generally used to monitor the wellbeing of both athletes and the general public to inform health specialists of future and often serious ailments. The problem facing these domain experts is the scale and quality of data they must search in order to extract meaningful results. By using peer-to-peer sensor architectures and a mechanism for reducing the search space, we can, to some extent, address the scalability issue. However, synchronisation and normalisation of distributed sensor streams remains a problem in many networks. In the case of pHealth sensor networks, it is crucial for experts to align multiple sensor readings before query or data mining activities can take place. This paper presents a system for clustering and synchronising sensor streams in preparation for user queries.

Abstract:
Introduction. Exercise-based cardiac rehabilitation (CR) independently alters the clinical course of cardiovascular diseases resulting in a signi cant reduction in all-cause and cardiac mortality. However, only 15%–30% of all eligible patients participate in a phase 2 ambulatory programme. The uptake rate of community-based programmes following phase 2 CR and adherence to long-term exercise is extremely poor. Newer care models, involving telerehabilitation programmes that are delivered remotely, show considerable promise for increasing adherence. In this view, the PATHway (Physical Activity Towards Health) platform was developed and now needs to be evaluated in terms of its feasibility and clinical efficacy. Methods and analysis. In a multicentre randomised controlled pilot trial, 120 participants (m/f, age 40–80 years) completing a phase 2 ambulatory CR programme will be randomised on a 1:1 basis to PATHway or usual care. PATHway involves a comprehensive, internet- enabled, sensor...

Abstract:
Purpose: Cardiorespiratory fitness (CRF) is generally regarded as an objective and reproducible measure of recent habitual physical activity (PA). Considering that the majority of daily PA is performed at light intensity, it is likely that CRF benefits will be detected at submaximal rather than maximal exercise. The purpose of this study was to evaluate daily minutes of light (LIPA), moderate (MIPA) and vigorous (VIPA) intensity physical activity among men with cardiovascular disease (CVD), and to determine the relation between PA and submaximal (oxygen uptake efficiency slope (OUES)) and maximal (V̇O2 peak) indices of CRF. Methods: A total 32 male participants (mean ( SD): age of 60.0 ± 8.7 yr, V̇O2 peak (L/min) 2.0 0.45, V̇O2 peak (mL/kg/min) 23.3 5.7, were recruited during an induction to a community based exercise referral program following completion of phase 2 cardiac rehabilitation.

Abstract:
Purpose: Physiologically based exercise prescriptions normally involve identifying an intensity range that elicits a predetermined VO2 or heart rate. In many instances prescribed exercise that exceeds an individual’s preferred level of intensity may establish a negative attitude toward physical activity. Longitudinal studies report that participants tend to deviate from physiologically based prescribed levels of intensity in favour of their apparently preferred levels. Self regulated exercise intensity may increase enjoyment and promote adherence by allowing individuals successfully complete an activity within their perceptual preference range and without undue physiological strain. This study examined the physiological and perceptual responses during self-regulated exercise in men with CAD. Methods: Eight men with CAD (65.7 ± 4.5 yr, VO2max 18.6 ± 4.1 ml/kg/min, BMI 29.7±3.3 kg/m-2) exercised on a treadmill for 20 min at a self regulated intensity. They were allowed to chan...
