Fitness

PAIesque helps athletes and fitness enthusiasts monitor their training through a simple three-step logic: 1. Measure training impulse (TRIMP) — The faster and longer your heart beats, the higher your daily score. 2. Analyze patterns over time — Track how your TRIMP accumulates and distributes 3. Monitor your body's response — Compare how your body reacts to training load PAIesque is different from commercial fitness apps (e.g. Garmin, Whoop, Polar). Every metric comes from published, peer-reviewed research with transparent methods that can be calculated from heart rate data alone. The app only includes metrics we can verify and reproduce from first principles — no proprietary black boxes, no undisclosed algorithms. And, all your data stays on your device. 1. TRIMP: • Banister TRIMP — The original exponential model with sex-specific coefficients (a=0.64/0.86, b=1.92/1.67) [Banister, 1991; Morton et al., 1990] • iTRIMP — Individualized TRIMP with customizable b coefficient (1.5-4.0) [Stagno et al., 2007; Akubat et al., 2012] • LT-TRIMP — Lactate Threshold-based model with β coefficient (0.04-0.11) and smooth transition at LT [Cheng et al., 1992; Mader et al., 1976; Gaesser and Poole, 1986] • PAI-esque — PAI-inspired metric using EWMA (not the official commercial algorithm) [Nes et al., 2017; Kieffer et al., 2021] 2. Patterns over time: • Intensity zones — Time and TRIMP spent in low/moderate/high zones (polarized training model) [Seiler and Tønnessen, 2009; Stöggl and Sperlich, 2014] • EWMA — Exponentially Weighted Moving Average for rolling loads (more sensitive than simple averages) • ACWR — Acute:Chronic Workload Ratio for injury risk monitoring (0.8-1.3 = sweet spot) [Murray et al., 2017; Griffin et al., 2021; Gabbett, 2016] • Polarized Training Score — 0-100 measure of how closely your distribution matches your targets 3. Body's response: • Resting Heart Rate (RHR) — Calculated from your defined sleep window (adaptive percentile: 5th-15th) • Heart Rate Variability (HRV) — Daily RMSSD averages during sleep [Task Force, 1996; Plews et al., 2013; Buchheit, 2014] • EWMA trends — Exponentially weighted moving averages for both RHR and HRV (acute and chronic windows) • Combined interpretation — RHR ↓ + HRV ↑ = positive adaptation; RHR ↑ + HRV ↓ = possible fatigue Data Management: • CSV export/import • Complete backup/restore (db) • All data stays on your device — no accounts, no cloud uploads, no tracking Creative Use Cases: • Coach analyzing athletes — Import athlete exports, analyze charts, provide feedback • Research analysis — Export CSV files for custom analysis in R, Python, or spreadsheets • Switch between athletes — Use "Delete All Data" + CSV import to analyze multiple individuals Requirements: • Google Health Connect installed on your device • Heart rate (and HRV) data in Health Connect from your wearable device (Gadgetbridge, Garmin, Polar, Samsung, etc.) • Android 8.0 (API 26) or higher Note on PAI: Our PAI-esque implementation is NOT the official commercial PAI® algorithm (which is proprietary). It uses EWMA and scaled TRIMP values to provide a similar intensity-weighted weekly score. The 100 PAI target remains the evidence-based health outcome from the HUNT Study research.

Privacy Friendly Pain Diary can help you track pain. It allows you to make daily diary entries recording your condition and the intensity, location, nature and time of the pain you feel, as well as the medication you take and additional notes. Records of your pain can help health professionals gain an insight into the pain you are experiencing. The main view of the app is a calendar. A new diary entry can be added and existing diary entries can be viewed by selecting a day in this calendar. Diary entries can be exported to PDF. You have to specify a period of time for which the entries are to be exported. You also have the option to share that PDF. Privacy Friendly Pain Diary has a daily reminder function. If enabled, it displays a notification reminding you to make a diary entry if you have not made one yet. You can set the time at which you want to be reminded in the settings. How does Privacy Friendly Pain Diary differ from other similar apps? 1) Minimal permissions Privacy Friendly Pain Diary requires write access to your device’s storage if you wish to export your diary entries to PDF. All other features do not require any permissions. 2) Protection of privacy User data is not recorded, nor sent to any third party. The data you enter is only locally stored on your device. 3) No advertisements or tracking mechanisms Privacy Friendly Pain Diary distinguishes itself from many other applications in the way that it does not include any advertisements or tracking mechanisms. Advertisements can shorten battery life or consume mobile data, while tracking mechanisms can compromise privacy. Privacy Friendly Pain Diary belongs to the group of Privacy Friendly Apps developed by the SECUSO research group at Karlsruhe Institue of Technology. Privacy Friendly Apps are Android applications which are optimized regarding privacy. Further information can be found here: https://secuso.org/pfa.

Privacy Friendly Pedometer can count your steps in background, provides you an overview about your walked steps and allows you to define custom walking modes and notifications if the achievement of your daily step goal is in danger. The app requires minimal permissions (Run at startup and prevent phone from sleeping). It belongs to the Privacy Friendly Apps group developed by the research group SECUSO at Karlsruhe Intitute of Technology. More information can be found an secuso.org/pfa Privacy Friendly Pedometer can count your daily walked steps while it runs in background. It gives you an overview about your walked steps, distance and about the calories you have burned while walking. You can add and choose different walking modes with different step lengths, such as walking or running, to improve the calculation of distance and calories. In a special training mode you can track your training sessions. To each training session additional information, such as feeling or a description, can be added. What makes Privacy Friendly Pedometer different from other pedometers? 1. Minimal amount of permissions: * Run at startup: This permission is required to restart the step counting when your phone boots. * prevent phone from sleeping: On some devices the processor falls asleep and prevents counting steps. With this permission the app can keep the processor awake while counting steps. Most of Pedometer Apps in the Google Play Store require additional permissions. E.g. accessing the network or Internet which is mostly used to display advertisement. Some apps have access to GPS or telephony data. 2. No advertisement. Many other free apps in the Google Play Store dazzle annoying advertising and also shortens battery life.

The Perceived Stress Scale (PSS) is the most widely used psychological instrument for measuring the perception of stress. It is a measure of the degree to which situations in one's life are appraised as stressful. Items were designed to tap how unpredictable, uncontrollable, and overloaded respondents find their lives. The scale also includes a number of direct queries about current levels of experienced stress. The PSS was designed for use in community samples with at least a junior high school education. The items are easy to understand, and the response alternatives are simple to grasp. Moreover, the questions are of a general nature and hence are relatively free of content specific to any subpopulation group. The questions in the PSS ask about feelings and thoughts during the last month. Evidence for Validity: Higher PSS scores were associated with (for example): - failure to quit smoking - failure among diabetics to control blood sugar levels - greater vulnerability to stressful life-event-elicited depressive symptoms - more colds Because levels of appraised stress should be influenced by daily hassles, major events, and changes in coping resources, predictive validity of the PSS is expected to fall off rapidly after four to eight weeks.

Ghosting is an established training exercise in racket sports to practice court movement without a ball. Moving to the various corners of the court improves both footwork and general stamina. In the best of worlds, your coach or sparring partner will always be ready to point you to random corners at a pace that pushes you to your limits. Unfortunately, few people have access to a coach at all times, thus have to run the exercise on their own. That means the randomness in the order of corners is missing. Getting Started 1. Configure your ghosting session. 2. Put your mobile device in front of you on the court. 3. Press "GO!" to start your ghosting session.
