    This study aimed to investigate the effect of repeated cooling of forearm muscle on adaptation in skeletal muscle metabolism. It is hypothesized that repeated decreases of muscle temperature would increase the oxygen consumption in hypothermic skeletal muscle. Sixteen healthy males participated in this study. Their right forearm muscles were locally cooled to 25 A degrees C by cooling pads attached to the skin. This local cooling was repeated eight times on separate days for eight participants (experimental group), whereas eight controls received no cold exposure. To evaluate adaptation in skeletal muscle metabolism, a local cooling test was conducted before and after the repeated cooling period. Change in oxy-hemoglobin content in the flexor digitorum at rest and during a 25-s isometric handgrip (10% maximal voluntary construction) was measured using near-infrared spectroscopy at every 2 A degrees C reduction in forearm muscle temperature. The arterial blood flow was occluded for 15 s by upper arm cuff inflation at rest and during the isometric handgrip. The oxygen consumption in the flexor digitorum muscle was evaluated by a slope of the oxy-hemoglobin change during the arterial occlusion. In the experimental group, resting oxygen consumption in skeletal muscle did not show any difference between pre- and post-intervention, whereas muscle oxygen consumption during the isometric handgrip was significantly higher in post-intervention than in pre-test from thermoneutral baseline to 31 A degrees C muscle temperature (P < 0.05). This result indicated that repeated local muscle cooling might facilitate oxidative metabolism in the skeletal muscle. In summary, skeletal muscle metabolism during submaximal isometric handgrip was facilitated after repeated local muscle cooling.

    Background: Human adaptability to cold environment has been focused on in the physiological anthropology and related research area. Concerning the human acclimatization process in the natural climate, it is necessary to conduct a research assessing comprehensive effect of cold environment and physical activities in cold. This study investigated the effect of cold water immersion on the exercise performance and neuromuscular function during maximal and submaximal isometric knee extension. Methods: Nine healthy males participated in this study. They performed maximal and submaximal (20, 40, and 60% maximal load) isometric knee extension pre-and post-immersion in 23, 26, and 34 degrees C water. The muscle activity of the rectus femoris (RF) and vastus lateralis (VL) was measured using surface electromyography (EMG). The percentages of the maximum voluntary contraction (% MVC) and mean power frequency (MPF) of EMG data were analyzed. Results: The post-immersion maximal force was significantly lower in 23 degrees C than in 26 and 34 degrees C conditions (P < 0.05). The post-immersion % MVC of RF was significantly higher than pre-immersion during 60% maximal exercise in 23 and 26 degrees C conditions (P < 0.05). In the VL, the post-immersion % MVC was significantly higher than pre-immersion in 23 and 26 degrees C conditions during 20% maximal exercise and in 26 degrees C at 40 and 60% maximal intensities (P < 0.05). The postimmersion % MVC of VL was significantly higher in 26 degrees C than in 34 degrees C at 20 and 60% maximal load (P < 0.05). The postimmersion MPF of RF during 20% maximal intensity was significantly lower in 23 degrees C than in 26 and 34 degrees C conditions (P < 0.05), and significantly different between three water temperature conditions at 40 and 60% maximal intensities (P < 0.05). The post-immersion MPF of VL during three submaximal trials were significantly lower in 23 and 26 degrees C than in 34 degrees C conditions (P < 0.05). Conclusions: The lower shift of EMG frequency would be connected with the decrease in the nerve and muscle fibers conduction velocity. To compensate for the impairment of each muscle fibers function, more muscle fibers might be recruited to maintain the working load. This might result in the greater amplitude of EMG after the cold immersion.

    Purpose This study investigated the effects of water temperature on cardiorespiratory responses and exercise performance during immersed incremental cycle exercise until exhaustion. Methods Ten healthy young men performed incremental cycle exercise on a water cycle ergometer at water temperatures (T-w) of 18, 26 and 34 degrees C. Workload was initially set at 60 W and was increased by 20 W every 2 min for the first four levels and then by 10 W every minute until the subject could no longer continue. Results During submaximal exercise (60-120 W), (V)over dotO(2) was greater at T-w = 18 degrees C than at 26 or 34 degrees C. Maximal workload was lower at T-w = 18 degrees C than at 26 or 34 degrees C [T-w = 18 degrees C: 138 +/- 16 (SD) W, T-w = 26 degrees C: 157 +/- 16 W, T-w = 34 degrees C: 156 +/- 18 W], whereas (V)over dotO(2) peak did not differ among the three temperatures [T-w = 18 degrees C: 3156 +/- 364 (SD) ml min-1, T-w = 26 degrees C: 3270 +/- 344 ml min-1, T-w = 34 degrees C: 3281 +/- 268 ml min-1]. Minute ventilation ((V)over dot(E)) and tidal volume (VT) during submaximal exercise were higher at T-w = 18 degrees C than at 26 or 34 degrees C, while respiratory frequency (f(R)) did not differ with respect to T-w. Conclusion Peak workload during immersed incremental cycle exercise is lower in cold water (18 degrees C) due to the higher (V)over dotO(2) during submaximal exercise, while the greater (V)over dot(E) in cold water was due to a larger V-T.

    The purpose of this study was to investigate the physiological and subjective responses of the European, Japanese (JPN) and US firefighters' helmet, gloves and boots for international standardisation. Three experimental conditions were evaluated (clothing mass: 9.4, 8.2 and 10.1kg for the three conditions, respectively) at the air temperature of 32 degrees C and 60% relative humidity. The results showed that there was no significant difference among the three conditions in oxygen consumption, heart rate, total sweat rate, rectal temperature and mean skin temperature, whereas peripheral temperatures and subjective perceptions were lower in the JPN condition than in the other conditions (P<0.05). These results indicate that a 0.5-kg reduction in helmet mass and a 1.1-kg reduction in boot mass during exercise resulted in a significant decrease in head and leg temperatures and subjective perceptions, while a 1.9-kg reduction in total clothing mass had insignificant influences on the metabolic burden and overall body temperature. Practitioner Summary: International, European or American standards on firefighters' helmet, boots or gloves stipulate minimum requirements for the protection of firefighters, whereas comfort functions are relatively neglected. The structural differences in the officially approved helmets, gloves and boots can reduce regional thermoregulatory burdens and improve subjective perceptions.

    Background: This study investigated the effect of hydration differences on body fluid and temperature regulation between tropical and temperate indigenes exercising in the heat. Methods: Ten Japanese and ten Malaysian males with matched physical characteristics (height, body weight, and peak oxygen consumption) participated in this study. Participants performed exercise for 60 min at 55% peak oxygen uptake followed by a 30 min recovery at 32 degrees C and 70% relative air humidity with hydration (4 times each, 3 mL per kg body weight, 37 degrees C) or without hydration. Rectal temperature, skin temperature, heart rate, skin blood flow, and blood pressure were measured continuously. The percentage of body weight loss and total sweat loss were calculated from body weight measurements. The percentage change in plasma volume was estimated from hemoglobin concentration and hematocrit. Results: Malaysian participants had a significantly lower rectal temperature, a smaller reduction in plasma volume, and a lower heart rate in the hydrated condition than in the non-hydrated condition at the end of exercise (P <0.05), whereas Japanese participants showed no difference between the two hydration conditions. Hydration induced a greater total sweat loss in both groups (P <0.05), and the percentage of body weight loss in hydrated Malaysians was significantly less than in hydrated Japanese (P <0.05). A significant interaction between groups and hydration conditions was observed for the percentage of mean cutaneous vascular conductance during exercise relative to baseline (P <0.05). Conclusions: The smaller reduction in plasma volume and percentage body weight loss in hydrated Malaysians indicated an advantage in body fluid regulation. This may enable Malaysians to reserve more blood for circulation and heat dissipation and thereby maintain lower rectal temperatures in a hydrated condition.

    The purpose of this study was to explore whether there is evidence of heat acclimatization in the words used to express thermal sensation. A total of 458 urban Japanese and 601 Indonesians participated in a questionnaire. In addition, in a preliminary survey, 39 native English speakers in the UK participated. Our results showed that (1) for Indonesians, the closest thermal descriptor of a feeling of thermal comfort was 'cool' (75%) followed by 'slightly cool' (7%), 'slightly cold' (5%) and 'cold' (5%), while Japanese responses were distributed uniformly among descriptors 'cool', 'slightly cool', 'neither', 'slightly warm', and 'warm'; (2) the closest thermal descriptors of a feeling of discomfort for Indonesians were less affected by individual thermal susceptibility (vulnerability) than those for Japanese; (3) in the cases where 'cool' and 'slightly cold' were imagined in the mind, the descriptors were cognized as a thermal comfortable feeling by 97% and 57% of Indonesians, respectively; (4) the most frequently voted choice endorsing hot weather was 'higher than 32A degrees C' for Indonesians and 'higher than 29A degrees C' for Japanese respondents; for cold weather, 'lower than 15A degrees C' for Japanese and 'lower than 20A degrees C' for Indonesians. In summary, the descriptor 'cool' in Indonesians connotes a thermally comfortable feeling, but the inter-zone between hot and cold weather that was judged in the mind showed a upward shift when compared to that of Japanese. It is suggested that linguistic heat acclimatization exists on a cognitive level for Indonesians and is preserved in the words of thermal descriptors.

    Background: In this study, we investigated the effects of duration of stay in a temperate area on the thermoregulatory responses to passive heat exposure of residents from tropical areas, particularly to clarify whether they would lose their heat tolerance during passive heat exposure through residence in a temperate country, Japan. Methods: We enrolled 12 males (mean +/- SE age 25.7 +/- 1.3 years) from south-east Asian countries who had resided in Japan for a mean of 24.5 +/- 5.04 months, and 12 Japanese males (age 24.1 +/- 0.9 years). Passive heat exposure was induced through leg immersion in hot water (42 degrees C) for 60 minutes under conditions of 28 C air temperature and 50% relative humidity. Results: Compared with the Japanese group, the tropical group displayed a higher pre-exposure rectal temperature (P < 0.01) and a smaller increase in rectal temperature during 60 minutes of leg immersion (P = 0.03). Additionally, the tropical group showed a tendency towards a lower total sweat rate (P = 0.06) and lower local sweat rate on the forehead (P = 0.07). The tropical group also had a significantly longer sweating onset time on the upper back (P = 0.04) compared with the Japanese groups. The tropical group who stayed in Japan for > 23 months sweated earlier on the forehead and upper back than those who stayed in Japan < 11 months (P < 0.01 and P = 0.03 for the forehead and upper back, respectively). There was a positive correlation between duration of stay in Japan and total sweat rate (r = 0.58, P < 0.05), and negative correlations between duration of stay and sweating onset time on the forehead (r = -0.73, P = 0.01) and on the upper back (r = -0.66, P = 0.02). Other physiological indices measured in this study did not show any difference between the subjects in the tropical group who had lived in Japan for a shorter time and those who had lived there for a longer time. Conclusions: We conclude that the nature of heat acclimatization of the sweating responses to passive heat exposure that are acquired from long-term heat acclimatization is decayed by a stay in a temperate area, as shown by the subjects in our tropical group. We did not find any evidence of a decay in the other physiological indices, indicating that heat tolerance acquired from long-term heat acclimatization is not completely diminished through residence in a temperate area for less than 4 years, although some aspects of this heat tolerance may be decayed.

    There are several types of cold adaptation based on the alteration of thermoregulatory response. It has been thought that the temperature of repeated cold exposures during the adaptation period is one of the factors affecting the type of cold adaptation developed. This study tested the hypothesis that repeated mild cold immersions would induce an insulative cold adaptation but would not alter the metabolic response. Seven healthy male participants were immersed to their xiphoid process level repeatedly in 26A degrees C water for 60 min, 3 days every week, for 4 weeks. During the first and last exposure of this cold acclimation period, the participants underwent body immersion tests measuring their thermoregulatory responses to cold. Separately, they conducted finger immersion into 5A degrees C water for 30 min to assess their cold-induced vasodilation (CIVD) response before and after cold acclimation. During the immersion to xiphoid process, participants showed significantly lower mean skin temperature and skin blood flow in the forearm post-acclimation, while no adaptation was observed in the metabolic response. Additionally, blunted CIVD responses were observed after cold acclimation. From these results, it was considered that the participants showed an insulative-type of cold acclimation after the repeated mild cold immersions. The major finding of this study was the acceptance of the hypothesis that repeated mild cold immersion was sufficient to induce insulative cold adaptation but did not alter the metabolic response. It is suggested that the adaptation in the thermoregulatory response is specific to the response which is repeatedly stimulated during the adaptation process.

    To examine the effects of firefighters' self-contained breathing apparatus' (SCBA) weight and its harness design on the physiological and subjective responses, eight male students performed treadmill exercise under four conditions: the 8 kg firefighter protective clothing (PC) (Control), the PC + an 11 kg SCBA with an old harness (Test A), the PC + a 6.4 kg SCBA with an old harness (Test B) and the PC + a 6.4 kg SCBA with a new harness (Test C), at ambient temperatures (T-a) of 22 degrees C and 32 degrees C. Besides highlighting the fact that a heavy SCBA had a significant effect on the oxygen consumption and metabolic rate, this experiment also found that in a T-a of 32 degrees C, in particular, the combined effect of 4.7 kg lighter SCBA and new harness design could reduce metabolic rate and improved subjective muscle fatigue and thermal discomfort. Practitioner Summary: An effort to alleviate the physiological and subjective burden of firefighters by reducing the weight of SCBA and by using the new harness design has provided satisfactory results in reduced oxygen consumption and in improved subjective responses in a hot air environment.

    For the coherent understanding of heat acclimatization in tropical natives, we compared ethnic differences between tropical and temperate natives during resting, passive and active heating conditions. Experimental protocols included: (1) a resting condition (an air temperature of 28A degrees C with 50% RH), (2) a passive heating condition (28A degrees C with 50% RH; leg immersion in a hot tub at a water temperature of 42A degrees C), and (3) an active heating condition (32A degrees C with 70% RH; a bicycle exercise). Morphologically and physically matched tropical natives (ten Malaysian males, MY) and temperate natives (ten Japanese males, JP) participated in all three trials. The results saw that: tropical natives had a higher resting rectal temperature and lower hand and foot temperatures at rest, smaller rise of rectal temperature and greater temperature rise in bodily extremities, and a lower sensation of thirst during passive and active heating than the matched temperate natives. It is suggested that tropical natives' homeostasis during heating is effectively controlled with the improved stability in internal body temperature and the increased capability of vascular circulation in extremities, with a lower thirst sensation. The enhanced stability of internal body temperature and the extended thermoregulatory capability of vascular circulation in the extremities of tropical natives can be interpreted as an interactive change to accomplish a thermal dynamic equilibrium in hot environments. These heat adaptive traits were explained by Wilder's law of initial value and Werner's process and controller adaptation model.

    The objective of this study was to investigate thermoregulatory responses to heat in tropical (Malaysian) and temperate (Japanese) natives, during 60 min of passive heating. Ten Japanese (mean ages: 20.8 +/- 0.9 years) and ten Malaysian males (mean ages: 22.3 +/- 1.6 years) with matched morphological characteristics and physical fitness participated in this study. Passive heating was induced through leg immersion in hot water (42A degrees C) for 60 min under conditions of 28A degrees C air temperature and 50% RH. Local sweat rate on the forehead and thigh were significantly lower in Malaysians during leg immersion, but no significant differences in total sweat rate were observed between Malaysians (86.3 A +/- 11.8 g m(-2) h(-1)) and Japanese (83.2 A +/- 6.4 g m(-2) h(-1)) after leg immersion. In addition, Malaysians displayed a smaller rise in rectal temperature (0.3 A +/- 0.1A degrees C) than Japanese (0.7 A +/- 0.1A degrees C) during leg immersion, with a greater increase in hand skin temperature. Skin blood flow was significantly lower on the forehead and forearm in Malaysians during leg immersion. No significant different in mean skin temperature during leg immersion was observed between the two groups. These findings indicated that regional differences in body sweating distribution might exist between Malaysians and Japanese during heat exposure, with more uniform distribution of local sweat rate over the whole body among tropical Malaysians. Altogether, Malaysians appear to display enhanced efficiency of thermal sweating and thermoregulatory responses in dissipating heat loss during heat loading. Thermoregulatory differences between tropical and temperate natives in this study can be interpreted as a result of heat adaptations to physiological function.

    This study investigated the differences in heat dissipation response to intense heat stress during exercise in hot and humid environments between tropical and temperate indigenes with matched physical characteristics. Ten Japanese (JP) and ten Malaysian (MY) males participated in this study. Subjects performed exercise for 60 min at 55% peak oxygen uptake in 32A degrees C air with 70% relative humidity, followed by 30 min recovery. The increase in rectal temperature (T (re)) was smaller in MY during exercise compared to JP. The local sweat rate and total body mass loss were similar in both groups. Both skin blood flow and mean skin temperature was lower in MY compared to JP. A significantly greater increase in hand skin temperature was observed in MY during exercise, which is attributable to heat loss due to the greater surface area to mass ratio and large number of arteriovenous anastomoses. Also, the smaller increase in T (re) in MY may be explained by the presence of a significantly greater core-skin temperature gradient in MY than JP. The thermal gradient is also a major factor in increasing the convective heat transfer from core to skin as well as skin blood flow. It is concluded that the greater core-skin temperature gradient observed in MY is responsible for the smaller increase in T (re).

    Previous research suggests that water exercise (WE) improves bodily functions of the frail elderly, but there is as yet no research on the effect of once weekly WE. This study aims to compare the effects of once and twice weekly WE on bodily functions of frail elderly requiring nursing care in six months. The design is a prospective cohort study. Participants were assigned to two different exercise groups (once weekly group or twice weekly group; n = 35). Once weekly group participate in a 60-min exercise session once a week, for six months while twice weekly group attended the session twice a week. Exercise sessions were divided into a 10-min warm-up on land and 50 min of exercise in water. The 50-min WE program consisted of 20 min walking, 10 min activities of daily living (ADL) exercise, 10 min stretching and strength exercises, and 10 min relaxation in water. Muscle strength, flexibility, balance, mobility and ADL disability were measured before the beginning of intervention and three months and six months after the program had started. Significant differences between the once and twice weekly groups were found in flexibility and balance at 3-months and 6-months and lower muscle strength and ADL disability only at 3-months. These results from present study suggested that the effects of WE frequency in the fail elderly who require nursing care were different for each bodily function. (C) 2010 Elsevier Ireland Ltd.

    The purpose of the present study was to examine the discrepancies in rectal temperature (T (re)) at various depths. Nineteen young males performed two bouts of bicycle exercise and recovery. T (re) was simultaneously measured at depth of 4, 6, 8, 10, 13, 16, and 19 cm, alongside the measurement of skin temperatures. We found small but statistically significant differences by depth in the absolute T (re), the magnitude of rise in T (re) and the lag of response in T (re). During the stabilization stage before exercise, T (re) at 4 cm-depth was 0.5A degrees C lower than T (re) at 16 cm-depth (p < 0.05). As the depth measured in the rectum was shallower, the rise in T (re) during exercise was greater. However the rise in T (re) at 10, 13, 16 and 19 cm showed no systemic difference. Among seven depths, T (re) at 16 cm-depth had the most stable feature with the longest latent period (3.1 +/- A 1.3 min) and the smallest rise (0.8 +/- A 0.3A degrees C), while T (re) at 4 cm-depth was the most responsive to the change of exercise and rest with the shortest latent period (1.0 +/- A 0.6 min) and the greatest rise (1.2 +/- A 0.5A degrees C). The differences observed in the depths from 4 to 19 cm were offset by exercise to some extent. In summary, T (re) appeared in different manners according to the seven depths during the repetition of exercise and rest, but T (re) deeper than 10 cm-depth seemed to have no systematic differences.

    Typically, the scales for the measurement of thermal sensation have been formatted as categorical scales (CS). Emerging is the use of CS combined with visual analog scale (VAS) for the measurement of thermal sensation to improve the sensitivity of scales. However, reports are rare comparing the typical CS, standard VAS, and combined CS with VAS. Methodological and conceptual issues are arising with the combining of scales, but there are insufficient reports about the advantages and limitations of different scales. The present study compared 9-points categorical scale (9pts CS), VAS, and CS combined with VAS (graphic CS) through a questionnaire Survey (n = 988) and a controlled experiment during exercise (17 male subjects). Our results showed that graphic CS was more closely related to indoor air temperature for resting residents rather than VAS or 9pts CS. Around thermal neutral zone indoor environments, sensitivity to discriminate thermal sensation was the greatest for graphic CS. In particular, questionnaire responses to VAS showed a remarkable clustering around the thermal neutral zone. For dynamic exercising subjects, mean skin temperature was more closely related to graphic CS than 9pts CS. Our results indicated that graphic CS seemed to be more valid and sensitive than 9pts CS or VAS for the measurement of thermal sensation, but there are many issues to be considered when combining CS and VAS from the methodological and conceptual view points: definitions of terms, verbalizing with descriptors, number of category, scoring length, unipolar/bipolar construction, language translation, central terms, both anchor terms, orientation, color, etc. The above methodological and conceptual issues were discussed.

    The purpose of this study was to investigate ethnic differences in cutaneous thermal sensation thresholds and the inter-threshold sensory zone between tropical (Malaysians) and temperate natives (Japanese). The results showed that (1) Malaysian males perceived warmth on the forehead at a higher skin temperature (T(sk)) than Japanese males (p < 0.05), whereas cool sensations on the hand and foot were perceived at a lower T(sk) in Malaysians (p < 0.05); (2) Overall, the sensitivity to detect warmth was greater in Japanese than in Malaysian males, (3) The most thermally sensitive body region of Japanese was the forehead for both warming and cooling, while the regional thermal sensitivity of Malaysians had a smaller differential than that of Japanese: (4) The ethnic difference in the inter-threshold sensory zone was particularly noticeable on the forehead (1.9 +/- 1.2 C for Japanese, 3.2 +/- 1.6 degrees C for Malaysians, p < 0.05). In conclusion, tropical natives had a tendency to perceive warmth at a higher T(sk) and slower at an identical speed of warming, and had a wider range of the inter-threshold sensory zone than temperate natives.

    The purpose of this study was to investigate the effects of water exercise at a day service facility and the effects of water exercise frequency on health-related quality of life (HRQL). Participants (n = 30) were randomly separated into three groups: two indicating exercise frequency, at once-weekly or twice-weekly, and a control group. One-hour exercise intervention sessions were carried out once or twice a week, accordingly, for 24 weeks. The water exercise session comprised a warm-up on land, activities of daily living (ADL) exercises, stretching, strength training, and relaxation in water. HRQL was evaluated using the Medical Outcomes Survey Short-Form 36 (SF-36) questionnaire, and ADL disability was assessed using the Functional Independence Measure. Significant differences were found between pre- and 6 months in both the once- and twice-weekly groups in HRQL (p < 0.05). No significant difference was found among pre-, 3 months, and 6 months. The effect size between the once and twice groups was moderate in both the physical component summary (0.72) and mental component summary (0.75) at 3 months. ADL disability shows significant correlation with HRQL. Water exercise intervention at a day service facility improved participants' HRQL for 6 months by improving exercise habits and ADL disability. Furthermore, the HRQL change differed according to exercise frequency: twice-weekly exercise showed more rapid improvement than once-weekly.
