Robust Monitoring of Sport and Exercise
Published in Daniel Tze Huei Lai, Rezaul Begg, Marimuthu Palaniswami, Healthcare Sensor Networks, 2016
The “standard” of sport and exercise monitoring is the heart rate monitor. This crosses all sport boundaries and includes built-in monitors in modern exercise equipment, sports watches, cycle computers and other technologies. The mainstay of scientific monitoring of population exercise levels is the accelerometer, used to generate estimates of energy expenditure in daily activity. A more recent arrival is the sports global positioning system (GPS) device. The sports GPS is used in many sports including running, cycling, sailing and various football codes. With the continued advances in semiconductor technology, these monitoring systems are merging with wearable combined GPS and heart rate monitors that can wirelessly connect to external sensors and transmit to a base unit.

The incremental running test was conducted on a running treadmill (H/P/COSMOS Sports & Medical, Nussdorf-Traunstein, Germany). Participants walked at 5 km/h at a gradient of 1.5% for about 1 min to allow for customization. The test started at 5.8 km/h keeping the constant incline of 1.5%, while introducing an increasing speed of 1.44 km/h every 3 min until exhaustion. The incremental cycling test was performed on a cycling ergometer (Lode-Excalibur Sport, Lode Company, Groningen, Netherlands). Participants started pedalling on command at 90 rpm and 25 W (for women) or 40 W (for men), and the work load was increased by 25 W every 3 min until exhaustion. Heart rate was monitored continuously during both exercise tests using a wireless heart rate monitor (CardioPart 12 Blue, Amedtec, Aue, Germany). Rated perceived exertion with scores ranging from 6 to 20 (Borg, 1982) was assessed and the exercise time to exhaustion was recorded at the end of both exercise tests. Venous blood samples were collected before, immediately, 10-, and 60-min after the cessation of each exercise test. Blood samples were either instantly used for measurements of CK, AST, and Mb, or frozen at –80°C until further analysis.
