Run Tracking - map


Run Tracking – pace per km


Run Tracking – altitude


Run Tracking – heart rate

Advanced Trainings

Advanced trainings can be preprogrammed manually or by the personal trainer

Multiple training phases (e.g. warm-up, intervals, cool-down). Each phase:– is either target time or distance– is assigned a target pace– can include a recovery phase



Advanced Trainings

Personal Trainer

Creates personalized training programs based on:• Target race (10K, Half or full marathon)• Target time• Current condition (5 or 10K time)• Training days

Dynamically modifies trainings based on physical recovery assessed with Heart Rate Variability



Personal Trainer: Training Program

Personal Trainer

Feedback:• Each training is evaluated against what

was programmed. Phases score differently based on importance (e.g. intervals more important than warm-up)

Trainings can be modified based on current condition (reduce effort by 10%, delay by 1 day, cancel)

Based on Heart Rate Variability

• insights in the control mechanism of the cardiovascular system– autonomic regulation through the activity

of sympathetic and parasympathetic pathways of the ANS

• Heavy training is responsible for shifting the cardiac autonomic balance toward a predominance of the sympathetic drive



• 60 seconds HRV test implemented on the phone:– RR-intervals correction– Time and frequency features– Linear interpolation and hamming windowing for

frequency features

• Paced breathing – 8 breaths/minute to improve reliability/repeatability

(effect of respiration on HRV)

• Output: easy to interpret number between 1 and 10

• Compared against previous measurement and baseline (5 of the last 7 days)

VO2max Estimation


VO2max Estimation

Estimate level of cardiorespiratory fitness during training

• works similarly to submaximal vo2max tests, i.e. heart rate at a specific intensity can be used to estimate maximal oxygen uptake

• age-correction and localization of stationary heart rate implemented
