Winter Training Cold-Weather Strategies: Muscle Warm-Up and Clothing Layers Below 10°C

How Low Temperatures Affect the Body

1. Muscle Viscosity Rises Significantly

For every 1°C drop in muscle temperature:

• Muscle strength decreases by 4-6%
• Muscle contraction speed decreases by 5-8%
• Viscosity increases by 8-12%

In a 10°C environment, muscle strength without warm-up is 20-30% lower than in a 20°C environment.

2. Increased Cardiovascular Strain

Reactions triggered by cold air:

• Peripheral vasoconstriction, blood pressure rises by 10-20 mmHg
• Heart rate rises by 5-10 bpm
• Increased risk of coronary artery spasm (high-risk groups for heart disease)

3. Respiratory Tract Irritation

• Cold air triggers bronchoconstriction (exercise-induced asthma)
• Dry mucous membranes; sensitive individuals prone to coughing
• In severe cases, chest tightness and wheezing

4. Injury Risk Multiplies

The likelihood of strains, sprains, and muscle tears in cold environments is 2-3 times higher than at normal temperatures.

Clothing Layer System

The 3-Layer System Principle

Base Layer: Moisture wicking

• Materials: Polyester, Merino Wool, Polypropylene
• Weight: 100-150 g/m²
• Function: Wicks sweat to outer layers, keeps skin dry
• Absolutely avoid: Pure cotton (turns into ice once soaked with sweat)

Mid Layer: Insulation

• Materials: Fleece, down, Primaloft, Polartec
• Weight: 100-300 g/m²
• Function: Traps air, retains heat
• For running: thin fleece 100-150 g/m²

Outer Layer: Wind and rain protection

• Materials: Gore-Tex Infinium (windproof), Gore-Tex Active (rainproof)
• Breathability: RET < 13 (the lower, the better)
• Important: underarm ventilation zippers

Clothing Recommendations by Temperature

Based on a 60-minute E-pace run:

Temperature	Base Layer	Mid Layer	Outer Layer	Head	Hands
15-20°C	Short sleeves	—	—	Cap	None
10-15°C	Long sleeves	—	Windbreaker (only if windy)	Cap	Thin gloves
5-10°C	Heavy long sleeves	—	Windproof jacket	Beanie	Medium-thick gloves
0-5°C	Thermal long sleeves	Thin fleece	Windproof and water-repellent jacket	Beanie + neck gaiter	Thick gloves
< 0°C	Thermal long sleeves	Medium fleece	Windproof and rainproof jacket	Full balaclava	Two layers of gloves

Lower Body Pairing

Temperature	Pants
15-20°C	Shorts
10-15°C	Thin tights or shorts + calf sleeves
5-10°C	Medium-thick tights
0-5°C	Tights + wind pants
< 0°C	Thermal tights + windproof outer pants

The “2-Layer Start, 1-Layer Cruise” Strategy

A common winter running mistake: dressing just right.

The correct approach:

1. Start with one extra layer (feel slightly cold when heading out)
2. After 10-15 minutes of running, the body warms up
3. Take off the second layer and tie it around your waist
4. Cruise at just the right amount
5. Put the second layer back on immediately after finishing (to avoid catching a cold)

Why this works:

• You won’t lose body heat during the pre-run warm-up
• You won’t overheat and sweat excessively mid-run
• You won’t get chilled when putting on sweat-soaked clothes after the run

Extended Winter Warm-Up Protocol

Below 10°C, warm-up time should be extended by 50%:

Phase 1: Indoor Warm-Up (10 minutes)

Done at home or in the locker room:

• Walking lunges ×20
• High knees 30 reps ×3 sets
• Jumping jacks 30 reps ×3 sets
• Torso twists ×20
• Arm circles ×30

Goal: heart rate at 110-130 bpm, lightly sweating.

Phase 2: Outdoor Walking (3 minutes)

Don’t start running immediately after heading out. Brisk-walk for 3 minutes to let your body adapt to the cold.

Phase 3: Super Slow Jogging (5 minutes)

Run 1 min/km slower than E pace, gradually raising your heart rate.

Phase 4: Progressive Acceleration (5 minutes)

Gradually accelerate to your target E pace.

Total warm-up time: 23 minutes, 8 minutes longer than at normal temperatures.

Special Risk: Exercise-Induced Bronchoconstriction (EIB) Triggered by Cold Wind

Symptoms

• Wheezing and coughing 5-15 minutes into a run
• Chest tightness, difficulty breathing
• Increased phlegm
• Symptoms worsen after finishing (not improve)

High-Risk Groups

• Those with allergies
• History of rhinitis or sinusitis
• Child runners
• Chronic asthma patients
• Smokers

Prevention Methods

1. Extend warm-up to 25 minutes or more
2. Wear a mask or neck gaiter (pre-warms the air you inhale)
3. Avoid direct cold wind (choose a sheltered route)
4. Drink warm water 15 minutes before training
5. Severe asthma sufferers: consult a doctor, use bronchodilators

Managing an Attack

• Stop training immediately
• Move to a warm indoor area
• Breathe slowly and deeply, keep warm
• Seek medical attention if necessary

Cardiovascular Warning

Below 10°C, the risk of cardiovascular events during training increases by 30-50%. High-risk groups:

• Men over 50
• History of hypertension or diabetes
• Family history of heart disease
• Smokers
• First winter training after a sedentary period

Warning Symptoms (Stop Immediately)

• Chest pain, chest tightness (especially radiating to the left arm or jaw)
• Palpitations, dizziness
• Numbness in hands or feet
• Unusual shortness of breath
• Cold sweats

If any of the above symptoms occur, stop immediately and seek medical attention.

Hydration and Energy Intake

Easy to overlook in winter: you can get dehydrated in cold weather too.

Why It Happens

• Breathing turns moisture from cold, dry air into vapor that you exhale
• Increased urination (cold-induced diuresis)
• Subjective thirst sensation drops by 30-40%
• Heavy clothing makes it hard to notice sweating

Winter Training Hydration Amounts

• Before training: 300-500 ml of warm water
• During training (< 60 minutes): 250 ml per 30 minutes
• During training (> 60 minutes): 250 ml per 20 minutes + electrolytes
• After training: body weight lost during training × 1500 ml

Note: Warm up sports drinks in winter; too-cold drinks affect gastrointestinal absorption.

Energy Intake

Winter training metabolic rate is 5-10% higher than in summer (extra expenditure goes toward maintaining body temperature):

• Runs over 90 minutes: 25-30g of carbs every 30 minutes
• 1.5 hours before training: complex carbs (oatmeal, sweet potatoes)
• Within 30 minutes after training: high protein + carbs (at a 4:1 ratio)

Post-Run Warmth

The most likely time to catch a cold after winter training:

Risk Points

1. Standing around chatting after finishing → body temperature drops rapidly
2. Taking off your jacket immediately → sweat evaporation carries away heat
3. Driving home without changing clothes → wet clothing against the skin
4. Taking a cold shower → vasoconstriction

The Right Approach

1. Cool down with a slow jog or brisk walk for 5 minutes (don’t stop suddenly)
2. Put on a warm jacket immediately (even if you feel hot)
3. Change out of all wet clothing within 30 minutes
4. Take a warm shower (40°C, 10-15 minutes)
5. Drink a warm beverage (ginger tea, hot cocoa)
6. Replenish protein and carbs

Timing Your Winter Training

Average daily temperature changes in Taiwan during winter:

Time Period	Temperature	Recommendation
05:00-07:00	Lowest	★★ (unless for a specific purpose)
07:00-10:00	Rising	★★★
10:00-14:00	Higher	★★★★★ (most recommended)
14:00-17:00	High	★★★★
17:00-20:00	Falling	★★★
20:00-23:00	Relatively low	★★

Conclusion: In winter, try to train between 10:00-14:00 and avoid the early morning.

Conclusion: Low Temperatures Are Another Kind of Challenge

Taiwan’s winter temperatures below 10°C pose a new challenge for runners who have long trained in 20-30°C conditions. Wear the right clothes, warm up thoroughly, and stay properly hydrated—winter training is not only doable, but it can also become the strongest foundation for spring races.

But always remember: when your body feels off, there is no such option as “just push through 5 more minutes.”
