“…It has been suggested that lower body temperature in the excessively obese may be an adaptation to reduced ability to dissipate heat (Chudecka et al 2014) to provide a buffer from incurring an excessively high temperature when ambient temperature is high and/or during physical exertion not unlike the adaptive response observed in heat trained athletes (Shvartz et al 1974). Under this scenario, a lower temperature could indicate more severe obesity and/or compromised cooling ability which, in turn, may threaten endurance performance and promote faster decline.…”

“…The only study that found obese persons to have a lower body temperature had a very small sample and found that the lower temperature occurred exclusively during daylight hours (Grimaldi et al 2015). Alternatively, other researchers have suggested that a lower basal temperature may be an adaptive response to compromised cooling ability associated with excessive adiposity (Chudecka et al 2014).…”

“…However, this theory has received little empirical support. Some studies failed to observe any significant association between body temperature and obesity (Chudecka et al 2014;Heikens et al 2011;Savastano et al 2009), and others found that obese persons tend to have higher average temperature (Hoffmann et al 2012). The only study that found obese persons to have a lower body temperature had a very small sample and found that the lower temperature occurred exclusively during daylight hours (Grimaldi et al 2015).…”

Scattered evidence indicates that a lower basal body temperature may be associated with prolonged health span, yet few studies have directly evaluated this relationship. We examined cross-sectional and longitudinal associations between early morning oral temperature (95.0-98.6°F) and usual gait speed, endurance walk performance, fatigability, and grip strength in 762 non-frail men (52 %) and women aged 65-89 years participating in the Baltimore Longitudinal Study of Aging. Since excessive adiposity (body mass index ≥35 kg/m 2 or waist-to-height ratio ≥0.62) may alter temperature set point, associations were also examined within adiposity strata. Overall, controlling for age, race, sex, height, exercise, and adiposity, lower temperature was associated with faster gait speed, less time to walk 400 m quickly, and lower perceived exertion following 5-min of walking at 0.67 m/s (all p ≤ 0.02). In the nonadipose (N = 662), these associations were more robust (all p ≤ 0.006). Direction of association was reversed in the adipose (N = 100), but none attained significance (all p > 0.22). Over 2.2 years, basal temperature was not associated with functional change in the overall population or non-adipose. Among the adipose, lower baseline temperature was associated with greater decline in endurance walking performance (p = 0.006). In longitudinal analyses predicting future functional performance, low temperature in the non-adipose was associated with faster gait speed (p = 0.021) and less time to walk 400 m quickly (p = 0.003), whereas in the adipose, lower temperature was associated with slower gait speed (p = 0.05) and more time to walk 400 m (p = 0.008). In older adults, lower basal body temperature appears to be associated with healthy aging in the absence of excessive adiposity.

“…The authors observed higher values in the trained group (n = 7, 0.009 ± 0.002 °C/s) than in untrained ones (n = 7, 0.004 ± 0.001 °C/s), although had no control of the subcutaneous fat layer of the studied region. Authors (Chudecka et al, 2014;Guyton and Hall, 2011) report that fat acts as a good insulator because it has a low thermal conductivity.…”

The influence of subcutaneous fat in the skin temperature variation rate during exercise

Introduction: Thermography records the skin temperature, which can be influenced by: muscle mass and subcutaneous fat layer. Thus, the aim of this study was to investigate the influence of subcutaneous fat layer in the skin temperature variation rate, during exercise. Methods: This is a short-longitudinal study that involved 17 healthy male trained volunteers. Volunteers were divided in two groups. The first called GP1 with nine volunteers (biceps brachii skinfold thickness < 4 mm) and the second called GP2 with eight volunteers (biceps brachii skinfold thickness from 4 to 8 mm). Both groups performed three sets with 16 repetitions of unilateral biceps brachii bi-set exercise with dominant arm (eight repetitions of biceps curls and another eight of biceps hammer curls, with dumbbells), and with load of 70% of 1RM. The rest time between sets was 90s. Results:The skin temperature variation rate (variation of temperature / time) was 3.59 × 10-3 ± 1.47 × 10-3 °C/s for GP1 and 0.66 × 10-3 ± 4.83 × 10-3 °C/s for GP2 (p = 0.138) considering all moments. For the period after set 1 until the end of set 3, skin temperature variation rate was 5.11 × 10-3 ± 2.57 × 10-3 °C/s for GP1 and 1.88 × 10-3 ± 3.60 × 10-3 °C/s for GP2 (p = 0.048). Subcutaneous fat layer also influences the skin temperature at resting (p = 0.044). Conclusion: Subjects with lower subcutaneous fat layer have a higher skin temperature variation rate during exercise than those with higher subcutaneous fat layer.

“…fat depot under the skin, subcutaneous fat) may act as insulation layers varying in expansion in dependence of ambient temperature and individual human. A study of surface skin temperature distribution in relation to body composition indicated a lower skin temperature of most body surfaces in obese women [41] than women of normal body mass because the local skin temperatures are influenced by subcutaneous adiposity. Among our studied athletes, higher temperature correlation coefficients with fat content were obtained in the most muscle zones for swimmers unlike ski-runners (Fig.…”

This study was focused on the thermal mapping of skin over the selected muscle zones in two groups of elite athletes fully engaged in completely other sports performing about an hour running effort at individual AT intensity. Two groups of elite male athletes, a group of cross-country skiers (CS; N = 6) and a group of elite endurance swimmers (SW; N = 4), were investigated. Thermal images of sportsmen' body at front and from the rear were recorded before and about 1-2 min after exercise test using camera Flir Systems E60. Functional (heart rate, oxygen uptake, workload) as well as biochemical markers (activities of creatine kinase and lactate dehydrogenase, concentration of lactate and haemoglobin) were also assessed. The marked differentiation in skin temperature distribution in cross-country skiers and endurance swimmers subjected to the same endurance exercise on treadmill was observed. There was significant decrease in temperature in upper body temperature in CS group, while SW group revealed a significant increase in temperature of the lower limbs. The calculated total body skin temperature was also influenced by practicing training of elite athletes. Some significant correlations of physiological, biochemical and morphological parameters (% fat) with average temperature after exercise test were found for different muscle zones in swimmers and cross-country skiers. Statistical analysis showed that workload had the most impact on skin temperature changes, especially in swimmers. The results provide additional information on the muscle work in the different sport disciplines and may be helpful in efficiency evaluation of elite athletes.
