The aim of this study was to determine the effects of using an electrical heating garment during a 30-min recovery period after a standardized swimming warm-up on subsequent swimming performance and upper body power output. On two occasions, eight male and four female elite competitive swimmers completed a standardized swimming warm-up, followed by a 30-min passive recovery period before completing maximal plyometric press-ups and a 50-m freestyle swim. Plyometric press-ups determined starting… 
Local Passive Warming Administered During the Transition Phase Impairs Subsequent Isokinetic Exercise Performance
Local passive warming administered during the transition phase was not an appropriate strategy for boosting the performance of subsequent isokinetic exercises, and the application of passive warming should be carefully chosen before exercise commences.
Transition phase clothing strategies and their effect on body temperature and 100-m swimming performance
Wearing warm clothing during a 30-min transition phase improved swimming performance by 0.6%, compared to limited clothing.
Improved 2000-m Rowing Performance in a Cool Environment With an External Heating Garment.
The data demonstrate that an upper-body external heating garment worn following a warm-up can improve rowing performance in a cool environment.
Sports and environmental temperature: From warming-up to heating-up
Recommendations are provided on how to build an effective warm-up following a 3 stage RAMP model (Raise, Activate and Mobilize, Potentiate), including general and context specific exercises, along with dynamic flexibility work.
Efecto del calentamiento activo y de diferentes intervalos de recuperación sobre el rendimiento en natación
Purpose: Determine the effect of active warm-up with different recovery intervals, in freestyle swimming performance, in 50m and 200m. Methods: Seven-teen athletes (13.5 ± 2.18 years), registered
Assessment of Sport Garments Using Infrared Thermography
Sport garments and their properties directly influence the heat exchanges occurring at the interface between the human skin and the environment. Active skin cooling or warming through innovative
Advanced Functional Materials for Intelligent Thermoregulation in Personal Protective Equipment
The exposure to extreme temperatures in workplaces involves physical hazards for workers. A poorly acclimated worker may have lower performance and vigilance and may therefore be more exposed to
Advanced Functional Materials for Intelligent Thermoregulation in Personal Protective Equipment
This review provides an overview and opinions of authors on the current state of knowledge on these types of technologies by reviewing and discussing the state of the art of commercially available systems and the advances made in previous research works.
Thermal-induced color-changing silver plating polyamide fabrics in low electric voltage
Abstract In this article, a simple and novel approach was presented for fabricating thermal-induced color-changing multi-layer composite fabrics (TICCF) with silver plating, polyurethane (PU)


Reducing muscle temperature drop after warm-up improves sprint cycling performance.
Passive heating of the thighs between warm-up completion and performance execution using pants incorporating electrically heated pads can attenuate the decline in Tm and improve sprint cycling performance.
External muscle heating during warm-up does not provide added performance benefit above external heating in the recovery period alone
External heating during an active warm up does not provide additional physiological or performance benefit, as noted previously, external heating is capable of reducing the rate of decline in Tm after an activewarm-up, improving subsequent sprint cycling performance.
Post-warm-up muscle temperature maintenance: blood flow contribution and external heating optimisation
Optimising the external heating procedure and increasing heating temperature of only 3 °C successfully maintained and even increased Tmvl, demonstrating that heating temperature is the major determinant of post-warm-up TmVL cooling in this application.
A Passive Heat Maintenance Strategy Implemented during a Simulated Half-Time Improves Lower Body Power Output and Repeated Sprint Ability in Professional Rugby Union Players
Passive heat maintenance reduced declines in Tcore that were observed during a simulated half-time period and improved subsequent PPO and repeated sprint ability in professional Rugby Union players.
Influence of post-warm-up recovery time on swim performance in international swimmers.
Relationship between power and sprint freestyle swimming.
It is concluded that power, as measured in this study, offers an objective assessment of a component essential for success in sprint swimming.
Effects of varying post-warm-up recovery time on 200-m time-trial swim performance.
A post-warm-up recovery time of 10 min rather than 45 min is more beneficial to 200-m swimming time-trial performance.

Two subjects performed isokinetic cycling at three different pedalling rates demonstrating that the magnitude of the temperature effect was velocity dependent: At the slowest pedalling rate the effect of warming the muscle was to increase PPmax by ∼2% per ‡ C but at the highest speed this increased to ∼10% per‡ C.
Muscle temperature and sprint performance during soccer matches – beneficial effect of re‐warm‐up at half‐time
It is demonstrated that in soccer, the decline in Tm and Tc during half‐time is associated with a lowered sprint capacity at the onset of the second half, whereas sprint performance is maintained when low‐intensity activities preserve muscle temperature.
