Cardio FAQ's General What user height range are your machines designed for? All products are designed for optimum use by users between 4'10" to 6'5" How are the calories calculated? On cycles, steppers, and treadmills, CYBEX uses the formulas established by the American College of Sports Medicine to calculate calories. Specifically for treadmills, the American College of Sports Medicine provides two formulas to predict calories expended: one for running and one for walking. Since the treadmill has no way of knowing whether the individual is walking or running, we make the assumption that you are walking if your speed is less than 3.0 MPH, and that you are running if your speed is greater than 5.0 MPH. For speeds between 3.0-5.0 MPH, we use a sliding scale to estimate the calories between the two different walking and running formulas. How accurate is the calorie counter on CYBEX products? Since CYBEX uses the ACSM formula on cycles, steppers, and treadmills to calculate calories, the results are as accurate as the formula. The gold standard for the measurement of energy expenditure is the actual measurement of oxygen consumed. Since that is not generally possible, the formulas were developed using data from oxygen consumption tests for each of the various machines at levels across a population of users. Where a significant factor like weight occurs it is included in the calculation on the machine. Beyond that the formula is as similar or different as two individuals doing the same thing can be in their use of oxygen which correlates directly to calories. As much as an absolute measure of calories burned, the indicated calories should be considered as a benchmark in ones overall consumption of energy. How accurate is the contact heart rate monitoring? Contact Heart Rate can be accurate to within +/- 1 BPM but in most cases should be used as a general indication as there are a variety of factors that can interfere with the quality of the signal such as: How long you have been holding on (hold at least 30 seconds for a more accurate reading) Excessive body movement (such as while running) Too tight or too loose grip Excessive dirt, powder, or oil on your hands/on the grips Why does contact heart rate sometime fail to pick me up? Contaminants, such as hand lotions, oils or body powder, may come off on the contact heart rate grips. These can reduce sensitivity and interfere with the heart rate signal. It is recommended that the user have clean hands when using the contact heart rate. What is the maximum user weight limit on CYBEX Cardio products? 750 Bikes/Treadmills/Arc Trainers: 400 lbs (181 kg) 600 Series Arc Trainers: 400 lbs (181 kg) 500 Series Bikes/Treadmills: 400 lbs (181 kg) 530S Stepper: 350 lbs (159 kg) 400 Series Treadmills: 350 lbs (159 kg) 360A Home Arc: 300 lbs (136 kg) 425A Arc Trainer: 300 lbs (136 kg) I want to do the Heart Rate Control Program (Program 9) but keep getting the message 'HR Signal Lost' The Heart Rate Control program requires the use of a telemetry strap for constant monitoring of heart rate. The heart icon will turn blue while it is acquiring the signal at the start of the program to confirm the presence of a signal. If your telemetry strap is not sending a signal you may encounter the message "HR Signal Lost". Make sure the back of the telemetry strap is wet to maximize conductivity. Bikes What does my score on the Fitness test mean? This score is an Age Predicted V02 max score. Like the calories displayed this should be used as a general guideline towards your fitness goals. There are different scores for men and women. What are the different MODES of operation on the 750 Cycles? CYBEX 750 Cycles have three different and unique modes of operation: Bike Mode, Constant Power mode, and Isokinetic Mode. What is Bike Mode? Bike mode is designed to simulate real world feel. Like on a regular bike, as you pedal faster your speed will increase and the resistance (watts) will increase proportionally. Changing gears (levels) will increase how much the wattage ramps up as your speed increases. What is Isokinetic Mode? This mode of operation is sometimes called ‘accommodating resistance.’ In Isokinetic Mode you’ll set a specific RPM (Revolutions Per Minute) to pedal. As you attempt to exceed your set RPM, resistance will be applied to keep you there. Dropping below your set RPM will result in a decrease in resistance. What is Constant Power? This mode is really what it sounds like. There is a set level of resistance and you must push against it. Increasing your speed (pedaling or striding faster) will result in the resistance feeling easier. Inversely, decreasing speed will make the resistance feel harder. What is the difference between exercising on a recumbent cycle compared to an upright cycle? The primary difference is in the area of comfort. The recumbent has a larger seat base and a back rest to support the user. Traditionally, most have considered that a recumbent cycle placed more emphasis on the glutes. This is mostly in perception based on two things: 1) the hip is in a flexed position giving a stretch to the gluteal muscles and thus the sensation of tension, and 2) the user is sitting on the muscle itself making them more aware of its contribution. Arc Trainer Why should I enter my body weight on the Arc Trainer? Since the foot plates on the Arc Trainer are suspended and your entire weight is being held by those foot plates, entering your body weight allows the unit to adjust the torque according to your body weight. The default body weight is 150lbs. How are calories calculated on the Arc Trainer? Since the ACSM does not have calorie tables for the Arc Trainer CYBEX developed its own Calorie tables using a statistically significant population with both males and females ranging from 18-64 years of age. Calories are calculated using the Incline, Strides per minute at the current resistance level and body weight. What is Adaptive Power Training on the 750 Arc Trainer? Adaptive Power Training is a form of accommodating resistance. All you need to do in this mode is select your level and start working out. The faster you stride the harder it gets. The higher the level selected (1-20) the faster the resistance will ramp up as you stride faster. The table below gives you an idea of Level 1 in Blue, level 10 in Red and 20 in green. How is distance calculated on the Arc Trainer? The Arc Trainer has a fixed stride length of 24” per stroke, or 48” per revolution. If you stride at an average of 120 SPM, that would be 240ft/minute or 2.72 mile per hour. Remember that you are always moving at an incline and this is why you will burn so many calories! What does the Incline level on the Arc Trainer relate to? Incline on the Arc Trainer relates to the incline of the path at the end positions of the pedal travel. At lower incline levels it will be more a striding motion whereas at the upper incline levels it will be more of a climbing type movement. Product Stride Length Minimum Incline Maximum Incline 360A 24" 16 25 425A 23" 15 26 6 and 7 series 24" 12 34 What is the distance between the footplates on the 360 Arc Trainer? The distance between the footplates on the 360A is 3" (46mm) My basement has 7’ high ceilings. Will the 360 Home Arc Trainer fit? We recommend 8" ceiling but it can fit 7" ceiling. The home Arc Trainer is designed with a very low step up height of only 8¼" to accommodate a wide range of users and various ceiling heights. Treadmills Why does the running deck look like it moves up and down when I run? All CYBEX Treadmills use Intelligent Suspension³ technology. Our IS³ deck suspension system is designed to work with the natural motion of running by allowing the front of the deck surface to move minimizing the impact your body must absorb at heel strike and then providing a stable surface from which to push off from. You spent all that time and money on good running shoes so why use a treadmill that is going to work against them? Do CYBEX treadmills work with wireless heart rate monitors? Yes. All CYBEX treadmills are compatible with 5Khz wireless heart rate straps. Why do I sometimes get a shock when I touch the treadmill? The shock is caused by a buildup of static electricity on your body. The friction between the deck and belt generates this static electricity. This is common among all treadmills but there are steps that you can take to mitigate this: keep the relative humidity of the room above 45%; replace the running belt when worn; people wearing nylon or wool clothing report occurrences of static discharge with greater frequency than those wearing cotton or polyester clothing. What does “Incline” on the Treadmill mean and what does it relate to? Incline on a CYBEX treadmill is expressed as a percentage instead of degrees. For example, if your treadmill is set to incline level 8, for every 100 feet you walk you will also be climbing 8 vertical feet. What is the maximum speed of CYBEX Treadmills? The maximum speed will vary depending on the model of the treadmill. Refer to the table below for the maximum speed that is possible. However, in the case of the 750T the maximum speed can be set lower at the discretion of the facility/owner. 750T 770T Pro3 CX-445T LCX-425T Product Number 751T 770T-CT 550T 445T 425T Speed Range 0.5 - 15.6 mph0.8 - 25 km/h 0.5 - 12.4 mph0.8 - 20 km/h 0.5 - 12.4 mph0.8 - 20 km/h 0.5 - 11 mph0.8 - 17.7 km/h 0.5 - 11 mph0.8 - 17.7 km/h Where can I find out more about using the treadmill?
