Abstract

PURPOSE:: To investigate the effects of uniquely processed titanium-permeated garments (Aquatitan) on performance of and recovery from high-intensity intermittent exercise. METHODS:: In a cross-over, 14 national- and regionally-competing male soccer/hockey players performed two 5-d trials comprising a Loughborough intermittent shuttle test on Day 1, followed by 4 d recovery assessment wearing randomly-allocated Aquatitan-treated and placebo clothing that covered their torso, limbs and feet continuously throughout the study. Repeated sprint time was measured during the shuttle test, and muscle damage, joint range of motion, isometric strength and running performance during recovery. RESULTS:: The increase in shuttle-test sprint performance (0.7%; 90% confidence interval +/-0.9%) was likely trivial. During recovery, wearing Aquatitan had a possible harmful effect on peak run velocity on Day 3 (-1.1% +/-1.6%) but a likely small benefit on Day 5 (2.0% +/-1.6%); combined (0.4% +/-1.3%) and standardized outcomes suggest an overall trivial benefit. Aquatitan increased range of motion. For example, voluntary leg extension increased 2.6% (+/-4.0%), hip flexion 1.8% (+/-1.2%), plantarflexion 4.8% (+/-2.8%), and shoulder extension and flexion 4.2% (+/-3.0%) and 1.3% (+/-0.6%) respectively; forced-voluntary differences at the hip and shoulder were trivial. Running efficiency was possibly increased on Day 3 and 5. Effects on isometric strength were largely trivial, but some enhancement of psychological state was observed. In a separate perception experiment, participants perceived tactile differences that were influenced by knowledge of treatment. CONCLUSIONS:: For competitive sub-elite male soccer/hockey players, performance gains in response to wearing Aquatitan-treated garments are likely of trivial consequence. However, improved joint range of motion during recovery indicate the garments reduced muscle-tendon stiffness suggesting enhanced compliance, which warrants further investigation. Garment feel may also offer some explanation for outcomes.​
