Fall and winter are the busiest injury seasons for physiotherapy clinics across Mississauga. Hockey leagues restart, ski trips get booked, and runners who trained all summer suddenly face dark mornings, cold muscles and slick sidewalks. Good sports injury prevention physiotherapy is the difference between a full season of play and six weeks on the sidelines — and most of the work happens before anything hurts.
This guide walks through the injuries we see most between October and March, the warm-up and strength work that actually reduces risk, the early warning signs of overuse, and when it makes sense to book an assessment instead of waiting it out.
The injuries we see most in fall and winter
Cold weather does not injure you on its own. What it does is change how you move: muscles are stiffer at the start of activity, surfaces are less predictable, daylight is shorter, and many people jump from a sedentary week straight into a high-intensity weekend. That combination produces a fairly predictable list.
Hockey: groin, hip flexor and shoulder
Adductor (groin) strains dominate hockey injury lists because skating loads the inner thigh repeatedly at long muscle lengths. Hip flexor strains follow the same pattern. Shoulder injuries — AC joint sprains and rotator cuff irritation — come from board contact and falls. Most groin strains are preventable with off-ice adductor strengthening, which is one of the few interventions with strong evidence behind it.
Skiing and snowboarding: knees and wrists
Skiers tear ACLs; snowboarders break wrists. The mechanism differs — a ski binding that does not release twists the knee, while a snowboarder instinctively catches a fall with an outstretched hand. Both groups also arrive after a year off with legs that have not done sustained eccentric quad work since last winter.
Running: Achilles, shin and plantar fascia
Cold, hard pavement and a shift to indoor treadmill running change stride mechanics. Achilles tendinopathy, medial tibial stress syndrome (shin splints) and plantar fasciitis all climb in the fall, usually in runners who increased mileage or changed surfaces abruptly.
Everyday winter: slips, shovelling and back strain
You do not need to play a sport to get a winter injury. Falls on ice cause wrist fractures and tailbone injuries, and snow shovelling — repeated flexion and rotation under load, often first thing in the morning — is a reliable cause of low back strain.
Warm-up and mobility: what to actually do
The single most common mistake is static stretching a cold muscle and calling it a warm-up. A warm-up should raise tissue temperature, take joints through the ranges the sport demands, and prime the nervous system with a few fast movements.
A practical 10-minute structure:
- 3 minutes general — easy cycling, skipping, or a brisk walk/jog until you feel warm and slightly out of breath.
- 4 minutes dynamic mobility — leg swings front-to-back and side-to-side, walking lunges with a rotation, hip openers, thoracic rotations, ankle rocks against a wall.
- 3 minutes sport-specific ramp-up — progressively faster strides for runners, short accelerations and change of direction for team sports, a few controlled squats and hops before skiing.
Save long static stretches for after activity or a separate mobility session. In cold outdoor conditions, add time — a warm-up that works in July is too short in January, and the first ten minutes of an outdoor run should be treated as part of the warm-up rather than part of the workout.
Strength work that prevents ACL and ankle injuries
Prevention programs work, and they are unglamorous. The components that show up in every effective protocol are the same ones most recreational athletes skip.
Eccentric and single-leg strength
Nordic hamstring curls, Bulgarian split squats, single-leg Romanian deadlifts and heel-raise progressions build the capacity to absorb force, not just produce it. Most non-contact ACL and ankle injuries happen during deceleration and landing, so training the braking phase matters more than adding weight to a bilateral squat.
Landing and cutting mechanics
Drop-jumps to a quiet, soft landing with knees tracking over toes, then progressing to single-leg hops and controlled change-of-direction drills, retrains the movement patterns that put the knee at risk. Two short sessions a week is enough for most recreational athletes.
Balance and proprioception
Single-leg balance progressions — eyes closed, then on an unstable surface, then with a reaching or throwing task — reduce repeat ankle sprains. If you have sprained an ankle before, this is the highest-value five minutes in your week.
Hip and trunk control
Weak hip abductors let the knee collapse inward under load. Side planks, banded lateral walks and hip hinge patterns address the whole chain. For runners and anyone with recurring foot or arch pain, footwear and support also play a role — see our guide to custom orthotics in Mississauga for how we assess whether that is a factor for you.
Recognizing overuse early
Acute injuries announce themselves. Overuse injuries whisper for weeks, and the athletes who catch them early lose days instead of months. The pattern to watch for:
- Stage 1: Pain after activity only, settles overnight. This is the moment to adjust load.
- Stage 2: Pain during activity that eases once you are warm, returns afterward.
- Stage 3: Pain that persists during activity and affects performance or technique.
- Stage 4: Pain with daily activities — stairs, walking, sleeping.
Other early signals: morning stiffness in a specific tendon lasting more than 30 minutes, a limp you only notice in the last kilometre, swelling that returns after every session, or one side consistently fatiguing before the other. A useful rule is the 24-hour test — if symptoms have not returned to baseline a day after activity, the load was too high.
When to see a physiotherapist versus rest it out
Rest alone is reasonable for a mild, short-lived ache after an unusually hard session. Book an assessment when any of the following apply:
- Pain has lasted more than 7–10 days despite reduced activity
- You cannot bear weight, or the joint gives way, locks or feels unstable
- There was an audible pop or immediate significant swelling
- Numbness, tingling or weakness is present
- It is the same injury you have had before — recurrence means something was never fully rehabilitated
- You have a season, race or trip coming up and need a plan rather than a guess
An assessment is also worth booking before the season if you are returning to a sport after a long break, coming back from a previous injury, or starting something new. A pre-season screen takes one appointment and usually produces a short, specific home program.
For acute injuries, the current guidance has moved on from RICE. The first 48 hours are about protection and gentle, pain-free movement rather than complete immobilization: protect the area, avoid aggravating activity, use compression and elevation for swelling, and reintroduce loading early under guidance. Our sports injury treatment page outlines how we structure that return-to-play progression.
Frequently asked questions
How long before the season should I start a prevention program?
Six to eight weeks gives strength and tendon capacity time to adapt. If the season has already started, it is still worth beginning — most of the benefit comes from consistency, not timing.
Does stretching before exercise prevent injury?
Static stretching before activity has not been shown to reduce injury rates and can briefly reduce power output. Dynamic warm-ups do help. Keep static stretching for after training or as its own session.
Is it safe to train through mild pain?
Low-level discomfort (roughly 3/10 or less) that does not worsen during activity and settles within 24 hours is usually acceptable while you address the cause. Pain that increases as you go, or that lingers the next day, means the load needs to change.
Is physiotherapy covered by my insurance?
Most extended health plans in Ontario include physiotherapy, often with a per-visit or annual maximum, and many do not require a doctor’s referral. We explain the details in our guide to health insurance coverage for physiotherapy in Ontario.
What should I do immediately after a slip on ice?
If you can bear weight and there is no deformity or severe pain, protect the area, apply compression, and move gently within a comfortable range. Seek same-day medical assessment for an inability to bear weight, visible deformity, numbness, or a head impact.
Get ahead of the season
Almost every injury we treat in January traces back to something that could have been addressed in October: a warm-up that was too short, a strength gap on one side, a load increase that was too fast, or a niggle that was ignored for three weeks. A single assessment is usually enough to identify which of those applies to you and to build a program you can do at home in fifteen minutes, twice a week.
If you are heading into hockey, ski season or winter running — or if last season ended with an injury you never fully rehabbed — book an assessment with our Mississauga team and start the season with a plan instead of a wrap.
