How to use ithlete
When should I use ithlete?
Where should I use ithlete?
The ithlete Finger Sensor should always be used whilst sitting. Why? Research has shown this to provide the strongest correlation to gold standard ECG measurement. Using a HRM chest strap most users can take their ithlete measurement sitting down. Why? HRV research studies have found that HRV is distorted when lying down in people with very low resting heart rates (50 and under). Standing (or even sitting) will raise this by a few bpm because your heart has to work a little more to pump blood uphill. Therefore only very fit users should ideally measure standing. The most important thing to remember is to be consistent. Click for more information, or why not check out our Frequently Asked Questions.
Taking your ithlete measurement
1a. Connect the ithlete Finger Sensor
Plug in to the headset socket of your compatible phone or tablet. If using ithlete for the first time you will need to select the Finger Sensor option from the ithlete app Settings ⇒ Choose sensor and follow the instructions page. We recommend watching this short video to enhance sensor performance.
1b. Connect polar type HRM chest strap and ithlete ECG receiver
Ensure your HRM chest strap is compatible and plug the ithlete ECG receiver into the headset socket of your device. Check it is firmly in place (you will hear a click) with the logo facing forwards. Select the ‘ECG receiver’ option from the app Settings ⇒ Choose sensor.
1c. Connect Bluetooth Smart HRM chest strap
Put on your Bluetooth Smart HRM chest strap (ensuring the skin contact patches are moistened), open the ithlete app, go to Settings ⇒ Choose sensor and follow the on-screen instructions to connect.
2. Wait for start button to turn green
3. Follow 60 second paced breathing exercise
The heart speeds up when you inhale. The gap between heartbeats (HRV) is therefore affected by your breathing. We ask users to follow the paced breathing exercise to ensure consistency of measurement.
4. Add subjective metrics
Upon completing your ithlete HRV measurement you are presented with the option to record 6 lifestyle factors; sleep, fatigue, muscle, stress, mood and diet. Use the sliding scales to record as you wish. We recommend tracking these areas to enable easier identification of trends and patterns in relation to your HRV scores. You can also record training load and any comments.
Interpreting your results
1. Your daily ithlete HRV Score
This is your HRV score and is conveniently colour coded to give you the day’s training recommendation.
Green = Very good recovery, you are ready to train
White = close to baseline, workout as normal
Amber = Light (aerobic) exercise or active recovery
Red = Rest
2. Daily, weekly and monthly change
Use the Dashboard to view your HRV scores and baseline over time at a glance. Turn the device landscape to view the detailed chart allowing you to explore the relationship between HRV, training load and subjective feelings (which we recommend you record to help you learn what works for your body!). Tap the charts to change the timescale.
4. Detailed analysis with ithlete Pro
Make the most of monitoring HRV by utilising ithlete Pro to analyse data in more detail and receive specific training guidance. Available from any web browser ithlete Pro also stores your data in the cloud keeping it safe and allowing you to monitor across devices.
