StrideCoach

Many runners try to run faster by pushing harder. But one of the most effective biomechanical adjustments requires no extra strength: Adjusting cadence. StrideCoach measures cadence using  BiomechEngine™, developed by Beflex’s biomechanics research team , extracting dominant stride frequency from head-based motion signals captured by AirPods. What Is Cadence? 4 Cadence is the number of steps you take per minute (SPM). Typical recreational runners: 155–170 SPM Efficient distance runners: Often 170–185 SPM (pace dependent) Cadence is not a magic number. It is a  mechanical control variable . Why Cadence Matters Low cadence often leads to: Overstriding Increased braking force Higher vertical loading rate Longer ground contact time Increasing cadence by just 5–10% has measurable biomechanical effects. Research Evidence Heiderscheit et al., 2011  – Increasing step rate by 10% reduced hip and knee joint loading. Lenhart et al., 2014  – Higher cadence reduced patellofemoral...

Most runners assume they move symmetrically. In reality, perfect symmetry is rare. Small asymmetries — repeated thousands of times — can create unilateral overload. StrideCoach measures  left–right balance using BiomechEngine™, developed by Beflex’s biomechanics research team , transforming head-based motion signals from AirPods into symmetry metrics. What Is Left–Right Balance? 4 Left–right balance refers to how evenly load and timing are distributed between legs. In symmetrical running: Stride timing is consistent Impact magnitude is similar Rhythm is stable When asymmetry increases: One leg absorbs more force One side fatigues faster Joint stress becomes uneven Over time, this imbalance accumulates. Why Symmetry Matters Research links gait asymmetry to injury risk and musculoskeletal stress imbalance. Evidence Zifchock et al., 2008  – Deviations from symmetry associated with injury history in runners. Queen et al., 2020  – Gait asymmetry contributes to uneven musculosk...

  Powered by Beflex’s BiomechEngine™ Most runners track pace. Very few track  impact . But impact loading — not speed — is one of the strongest biomechanical predictors of overuse injury. StrideCoach measures impact using  BiomechEngine™, developed by Beflex’s biomechanics research team , transforming raw motion data from AirPods into meaningful loading metrics. What Is Running Impact? 4 Impact refers to the  acceleration spike that occurs at foot strike . When your foot hits the ground: A rapid deceleration occurs Ground reaction forces travel upward Bones, cartilage, and soft tissues absorb the load This loading happens hundreds — sometimes thousands — of times per run. The problem is not one impact. It is  repetition . Why Impact Matters Research has consistently linked higher vertical loading rates to injury risk. Evidence Milner et al., 2006  – Runners with tibial stress fractures showed significantly higher vertical loading rates. Zadpoor & Nikooy...

StrideCoach is built on  BiomechEngine™, a biomechanics analysis engine developed by Beflex’s research team specializing in human movement science . Unlike generic fitness apps, BiomechEngine is grounded in: Biomechanics research Signal processing algorithms Motion symmetry analysis Frequency-domain gait analysis It transforms raw IMU sensor signals into clinically meaningful running metrics. The 5 Core Metrics — With Research Foundations 1. Impact (Landing Shock) 4 What it measures: Acceleration peak at foot strike, reflecting impact loading. Why it matters: Higher impact loading is associated with increased injury risk, particularly tibial stress fractures and knee pain. Research Evidence: Milner et al., 2006 – Higher vertical loading rates observed in runners with tibial stress fractures. Davis et al., 2016 – Impact reduction linked to lower injury risk in gait retraining studies. Zadpoor & Nikooyan, 2011 – Systematic review linking impact loading to running injuries. Imp...

Why Choose a Minimalist Running Pack? Minimalist running packs have become increasingly popular among runners who value lightweight comfort and carrying only the essentials. A streamlined pack can help you move effortlessly while still providing space for hydration and key items. Key Features to Consider Weight: Look for packs weighing under 300 grams. Every ounce counts during long runs. Fit: A snug fit prevents bouncing and chafing. Adjustable straps help customize the pack to your body. Hydration: Choose between bladder-compatible packs or those with front flask holders, depending on your preference. Storage: Minimalist doesn't mean impractical – ensure there are easy-access pockets for your phone, gels, and keys. Breathability: Mesh fabrics and ventilated panels help keep you cool. Popular Minimalist Running Packs Salomon ADV Skin 5 Set: Ultra-light, form-fitting, and comes with soft flasks. Nathan VaporKrar 2.0: Comfortable for longer hours and offers ample front storag...

Introduction Running is a popular form of exercise that offers numerous benefits for both the body and mind. One debate among runners is whether running in complete silence or with the backdrop of nature sounds can lead to a more enjoyable and effective experience. Running in Silence Mental Clarity: Running in silence allows for deep introspection. Without distractions, runners can focus on their breathing, stride, and thoughts, making it a meditative experience. Improved Awareness: Silence enhances awareness of one's body and surroundings. Runners respond better to how they feel physically and can be more attentive to the trail or road conditions. Stress Relief: The absence of auditory input can provide a break from the constant noise of daily life, leading to a greater sense of peace. Running with Nature Sounds Enhanced Mood: Listening to the gentle rustling of leaves, chirping birds, or flowing water can positively influence mood, making the run feel more enjoyable. Connecti...

Introduction Properly storing your running shoes for the long term helps maintain their shape, prolongs their lifespan, and ensures they’re ready for use when you need them again. Here’s a comprehensive guide to storing your running shoes so they remain in great condition. Why Proper Storage Matters Running shoes are designed with special materials that can degrade if not cared for correctly. Whether you’re taking a seasonal break or have a favorite pair you want to save, proper storage is essential. Steps for Storing Running Shoes Long-Term Clean Your Shoes: Remove any dirt, mud, or debris from the shoes. Use a soft brush and mild soap to clean the surface. Allow them to air dry completely before storage. Keep Them Dry: Moisture can cause mold, mildew, or unpleasant odors. Make sure shoes are completely dry. Stuff them with newspaper or use silica gel packets to absorb leftover moisture. Maintain Their Shape: Insert shoe trees or stuff the shoes with acid-free paper to help them re...
