Exercise increases heat production. During exercise in both warm and cold conditions, the major dilemma is the dissipation of the heat produced from muscular activity. The use of clothing generally represents a layer of insulation and as such imposes a barrier to heat transfer and evaporation from the skin surface. In warm environments, additional clothing increases thermal insulation causing more rapid increases in temperature during exercise and imposes a barrier to sweat evaporation. However… 

Impact of Clothing on Exercise in the Heat

The incorporation of protocols that more closely mirror sporting and recreational activity lasting >60 min as well as simulated work-related protocols lasting >120 min is warranted and the effects of clothing characteristics on comfort during exercise and recovery are considered.

Heat strain in cold.

In cold environment both the preservation of insulation and facilitation of heat loss are important, and development of clothing design is still needed to allow easy adjustments of thermal insulation.

The Role of Sports Clothing in Thermoregulation, Comfort, and Performance During Exercise in the Heat: A Narrative Review

The aims of this review are to (1) summarise the current research of sports clothing as it relates to thermoregulation, comfort, and performance during exercise in the heat, (2) identify

The effect of thermal insulation pads on heat flux, physical effort and perceived exertion during endurance exercise in cool environments

To determine the effects of thermal insulation pads on clothing surface temperature, physical effort and perceived exertion during endurance exercise in cool environments two different pants (PCOOL,

Influence of Clothing on Thermoregulation and Comfort During Exercise in the Heat

Results show that clothing fiber content and fabric construction had no effect on thermoregulation, RPE, or clothing comfort during moderate-intensity exercise in the heat; whereas synthetic fabric construction indeed effectively reduced regional microenvironment temperature and attenuated global exertion and TS, which may have important implications for exercise tolerance in theheat.

Thermoregulation during Exercise in the Heat

During heat acclimatisation, the temperature thresholds for both cutaneous vasodilation and the onset of sweating are lowered, which, in combination with plasma volume expansion, improve cardiovascular stability and nutritional intervention seem to be most effective.

Results were shown that clothing ensembles with mesh fabrics could influence the performance of heat and moisture transfer and the provision of mesh fabrics at appropriate positions in the T-shirts could be the key.

Physiological cost and thermal envelope: A novel approach to cycle garment evaluation during a representative protocol

Physiological cost provides a better index of clothing performance than deep body temperature in the “thermoregulatory zone,” as a consequence sports clothing should attempt to optimize the balance between comfort and reduced physiological cost.

Methods for improving thermal tolerance in military personnel prior to deployment

This review explores how heat acclimation (HA) prior to deployment may attenuate the effects of heat by initiating physiological and behavioural adaptations to more efficiently and effectively protect thermal homeostasis, thereby improving performance and reducing heat illness risk.



Clothing and Exercise

SummaryDespite large environmental variations, the human body maintains a tightly regulated core temperature. Effective thermoregulation must balance the interaction between skin surface, clothing

Clothing and Exercise

Thermoregulatory studies often investigate thermal responses without considering the influences of clothing, but the importance of clothing and the influence of new clothing technology aimed at minimising thermal stress has spawned a new interest.

Clothing fabric does not affect thermoregulation during exercise in moderate heat.

Neither the addition of a modest amount of clothing nor the fabric characteristics of this clothing alters physiological, thermoregulatory, or comfort sensation responses during or after exercise in a moderately warm environmental condition.

Exercise training improves tolerance to exercise in the heat by increasing the sensitivity of the sweat rate/core temperature relationship, decreasing the core temperature threshold for sweating and increasing total blood volume.

Six subjects exercised for 60 min on a cycle ergometer with an artificial ‘sun’ with a spectral distribution similar to sunlight and an intensity of 724 W m−2, and the sweat losses for white polyester and black cotton were significantly less than those for black cotton.

The percentage of evaporated sweat was found to be inversely proportional to total sweat loss and if more layers of clothing were added, or if water-proof or vapor-proof materials were added.

Sweating, discomfort and temperature sensations increased gradually with increasing Pa until critical Pa was reached above which M decreased and Tsk and HR increased rapidly, and sweating and discomfort sensations accelerated markedly.

In this chapter, a potpourri of examples of proper clothing to wear during various exercise demands in different environments are presented to show that the thermal biophysics and physiology of exercise follow similar fundamental pathways that can be highly pertinent.

Effect of physical activity and air velocity on the thermal insulation of clothing.

Intrinsic thermal clothing insulation and surface air insulation were measured on human subjects by the use of indirect calorimetry and showed that intrinsic clothing insulation was maximal in the standing position.
