For training fields, Vivaturf focuses on long-term wear resistance, impact protection, and structural stability.
The yarn system can be modified with wear-resistant and weather-resistant additives to improve resistance to repeated sprinting, sliding, turning, and daily foot traffic. The straight fibers help create a stable support framework, while the curled fibers help maintain cushioning and recovery.
The backing system is also critical. Vivaturf uses a reinforced multi-layer backing structure, which can include high-strength grid reinforcement and a stable fixation layer. This helps improve yarn anchoring and reduce the risk of yarn pull-out, backing cracking, or structural deformation under frequent use.
Typical training-field performance targets may include:
- Yarn wear resistance: up to 6,500 cycles under ASTM D3884 reference testing
- Yarn pull-out force: ≥35 N
- Shock absorption: 40%–55%
- Vertical deformation: 5–8 mm
- Compression set after 70°C × 22 h testing: ≤2%
- Wet-condition friction coefficient: ≥0.50
- UV aging resistance: up to 6,000 hours
- Annual mechanical performance decay: designed to remain low under normal use conditions
This makes the training version suitable for high-frequency daily use, athletic development programs, school training fields, club practice areas, and multi-purpose sports centers.
Technical Comparison: Training Field vs. Match Field
| Performance Focus | Match Field Requirement | Training Field Requirement | Vivaturf Adaptation |
|---|---|---|---|
| Surface uniformity | Very high | High | Match systems emphasize tighter field-wide performance tolerance |
| Ball response | Precise rebound and roll | Stable but more durability-oriented | Ball rebound 0.80–0.90, ball roll variation ≤5% for match-focused systems |
| Shock absorption | Balanced for competition | Stronger protection for repeated training | 40%–55% shock absorption range |
| Vertical deformation | Controlled and consistent | Balanced support and comfort | 5–8 mm target range |
| Wear resistance | Important | Very important | Training systems emphasize wear-resistant yarn and reinforced backing |
| Maintenance | Low and predictable | Low under high-frequency use | No sand or rubber infill, reduced infill-related maintenance |
| Environmental performance | Clean, low odor, low emission | Safe for daily athlete exposure | Low TVOC, no loose rubber granules, reduced dust concerns |
