Why your wearable is not accurate enough to know your VO₂max

From Garmin to Apple Watch to Whoop is seems like every company is coming out with a wearable that promises more data, more insight, and increasingly large promises for what their product can do for your long-term health. But are these claims justified? In the case of VO₂max, it seems like they are overpromising and under-delivering.

VO₂max Explained: What It Is, How It’s Calculated, and Why It Matters

VO₂max is one of the most powerful metrics that you can measure in exercise physiology when it comes to health and performance. From elite athletes to is regular people, VO₂max is an integrated measure of how well your heart (cardiovascular system), lungs (respiratory system) and muscles (metabolic system) function.

Safely returning to sport after a concussion

Concussions are functional brain injuries that affect how the brain works, and returning to sport too quickly can increase the risk of prolonged symptoms or more serious injury. Parachute Canada’s 6-step return-to-sport protocol provides a structured, evidence-based path to recovery, starting with symptom-limited daily activity and progressing through light exercise, sport-specific drills, non-contact training, full-contact practice, and finally a safe return to competition. Each step requires careful monitoring and at least 24 hours before advancing, with medical clearance needed before contact. Tools like the Ontario Online Concussion Assessment help ensure athletes receive timely evaluation, proper documentation, and safe guidance through each stage of recovery.

How do online concussion assessments work?

Virtual concussion assessments offer a structured, evidence-based alternative to in-person care, allowing patients across Ontario to access high-quality evaluation and rehabilitation remotely. These visits emphasize a detailed clinical history—covering mechanism of injury, symptom patterns, medical background, and functional demands—paired with a targeted virtual exam that screens neurological function, vision and vestibular systems, balance, gait, and the cervical spine. Treatment focuses on active rehabilitation supported by current research, including symptom-limited aerobic exercise, vestibular and oculomotor therapy, cervical spine management, return-to-work or school planning, and headache strategies. When needed, care is coordinated with other healthcare providers, and safety triage is built into every assessment. For many patients, virtual concussion care delivers accessible, individualized, and clinically rigorous support through the entire recovery process.
