Key Findings

01Heated garments significantly improved 15m sprint performance in both 2°C and 18°C conditions.
02Heated garments led to significant improvements in countermovement jump height and repeated sprint performance.
03Participants wearing heated garments reported feeling warmer, more comfortable, and more match-ready.

Application

Design takeaway

Integrate passive heating elements into athletic apparel designed for athletes who experience significant inactivity during competition to maintain muscle temperature and enhance performance.

How to apply

Develop and test prototypes of passive heating garments for sports where substitutes experience prolonged periods of inactivity, such as soccer, basketball, or hockey.

Project actions

01Consider how different materials retain heat and how this affects user comfort and performance.
02Think about the practicalities of wearing heated garments during sports, such as ease of movement and weight.

Method & Evidence

AimTo investigate the impact of passive heating garments on simulated soccer performance and perceptual responses in male soccer substitutes during periods of inactivity in both cold and thermoneutral environments.

MethodExperimental study

ProcedureTrained male soccer players completed a simulated match scenario as substitutes, wearing either standard tracksuit bottoms or heated trousers over their playing attire. Performance metrics and perceptual responses were recorded before and after the simulated inactivity period, and during a subsequent performance test.

ContextSports science, athletic performance, apparel design

Variables

IVType of garment worn (standard vs. heated)

DV15m sprint time, countermovement jump height, repeated sprint performance, perceived warmth, comfort, and match readiness.

CVEnvironmental temperature (2°C and 18°C), player training status, duration of inactivity, pre-warm-up protocol.

Strengths & Limitations

Strengths

+Controlled experimental conditions.
+Inclusion of both objective performance measures and subjective perceptual responses.

Limitations

It can be difficult to perfectly simulate real-world conditions and control all variables that might affect performance.

Reliability & validity

The study's use of controlled conditions and standardized performance tests enhances reliability. Validity is supported by the significant performance improvements observed and the alignment with physiological principles of thermoregulation.

Think critically

How might the effectiveness of passive heating garments vary across different sports, environmental conditions, and athlete types?

Design Principles

"Maintain optimal physiological conditions through material and garment design to support peak performance."

This research highlights a practical design opportunity for athletic apparel. By maintaining optimal muscle temperature during rest periods, designers can create garments that directly enhance athletic performance and readiness, addressing a key physiological factor in sports.

What This Means for Your Design

Wearing special warm pants when you're not playing in a soccer game helps you run faster and jump higher when you go back in.

Paragraph starter

Research indicates that passive heating interventions can significantly enhance athletic performance by maintaining optimal muscle temperature during periods of inactivity. For instance, a study by Cowper et al. (2025) found that heated garments improved sprint performance by up to 2.8% in soccer substitutes, demonstrating a direct link between garment design and physiological output.
