Summary: To address the challenges of urban heat, a 'human-centric' approach is essential, focusing on personalized characteristics of comfort and health. Current research emphasizes systematic review of personalized urban heat studies, with a need for future evaluations to focus on data accuracy and addressing knowledge gaps.

Summary: This study highlighted the direct effects of temperature conditions on pregnancy health, showing that maternal responses to heat exposure can impact fetal development and restrict placental growth. Additionally, differences in food intake and nesting behavior during pregnancy between standard housing and thermoneutral zone conditions emphasize the need for caution when extrapolating from animal models to humans.

Summary: With increasing global temperatures, it is crucial to study how wild animals respond to heat. Thermal imaging of the eye region provides a non-invasive method to measure temperature and understand thermoregulation and stress responses. However, there is limited knowledge about eye region temperature regulation and individual differences.

Summary: In many endotherms, using heat generated by active skeletal muscles to replace thermogenesis is an important energy-saving mechanism. This study found individual variation in the extent of substitution, with body length and heart mass positively correlated and surface area negatively correlated with substitution.

Summary: Through a simulated experiment of footbath, it was found that the skin temperature would increase while the core temperature would decrease after footbath. The higher the water temperature and the longer the footbath duration, the longer the core temperature would stay lower. The onset of sweating was inversely proportional to the water temperature. A relationship curve between sweating onset time and water temperature has been established to determine the optimal footbath conditions, which may facilitate sleep onset.

Summary: This study investigated the effects of prior heat exposure on upper-body endurance work capacity and maximal isokinetic arm and leg strength in young men. The results showed that prior heat exposure led to an increase in body temperature, resulting in a shorter time to exhaustion and decreased muscle strength. Workers should be cautious about the impact of heat exposure on their endurance and strength before engaging in manual labor.

Summary: This study explored whether medications related to thermoregulation modified the associations between maternal exposure to extreme heat events (EHEs) and congenital heart defects (CHDs) in offspring. The findings suggest that while overall there was no significant interaction, medications altering central thermoregulation did significantly modify the association between EHEs and CHDs in the Southwest region of the United States.

Summary: This study examines the impact of network-wide exposure to cyclists and motorised vehicles on bicycle crash frequency in Utrecht, a Dutch cycling capital. The results show that increasing exposure to motorised vehicles, and to a lesser extent, exposure to cyclists, increases the number of bicycle crashes on 50 km/h roads. For 30 km/h roads, no significant relationship between exposure to cyclists and bicycle crashes was found. Moreover, cyclist crashes on 30 km/h roads are less affected by an increase in exposure to motorised vehicles compared to 50 km/h roads. The study highlights the need for further improvements in road safety for cyclists.

Summary: This study investigates the thermoregulatory capacity of ostriches and finds that females with better regulation of head temperatures have higher egg-laying rates under hotter conditions. The study also reveals that thermoregulatory capacity is heritable and shows signs of local adaptation to temperature fluctuations. These findings suggest that thermoregulation in ostriches has evolved in response to past climatic conditions and is currently under selection through its effect on reproduction.

Summary: This study investigates the seasonal variations in thermoregulation efficiency and behavior of a lizard population on Naxos Island, Greece. The results show that seasonal fluctuations significantly influence the ability of lizards to regulate their body temperature, with summer being the most favorable and autumn being the least favorable. Lizards adjust their thermal preferences and thermoregulation efficiency depending on the challenges of each season, maintaining stable body temperatures.

Summary: The study highlights the underreporting of lower severity cycling collisions and single cyclist collisions, using self-reported survey data from Ireland to provide detailed information on these often overlooked incidents. This research emphasizes the importance of including these underreported collision types in cyclist safety priorities for a more comprehensive analysis.

Summary: The study found that small mammal communities in the Mojave Desert remained relatively stable, while bird populations declined significantly in response to warming and drying. This difference in response may be attributed to the different microhabitat use of birds and mammals.

Summary: This study aimed to explore the intraseasonal variation of the association between heat exposure and mortality risk during the warm season in Shandong province. The results showed a J-shaped association between ambient warm temperature and mortality risk during the warm season, with a greater impact of extreme heat in the early warm season. Females, elderly aged over 75 years, individuals with junior high school education or lower, and cardiorespiratory patients were more susceptible to heat exposure compared to other population subgroups. Therefore, it is important to develop health promotion strategies to mitigate the adverse effects of early heat.

Summary: Aerobic training with blood flow restriction (BFR) has potential benefits for endurance athletes, including improved physiological capacities and performance. However, implementing BFR training for endurance athletes requires additional considerations compared to non-endurance athletes.

Summary: This study examined the effects of blood flow restriction on cardiovascular, perceptual, and neuromuscular fatigue during and after cycling intervals. The results showed that blood flow restriction reduced the mechanical and cardiovascular demands of the intervals, without affecting perception of fatigue or neuromuscular characteristics.

Summary: This study examined the magnitude and reliability of rate of torque development (RTD) during a cycling sprint with altered resistance, duration, and pedal downstroke. The results suggest that the average of downstrokes 2 and 3 during a 5-second sprint with heavy or very heavy resistance is the most reliable measurement of RTD in sprint cyclists.

Summary: This study investigated whether walking with blood flow restriction (BFR) can increase cardio-respiratory demands and serve as an alternative to jogging. The results showed that moderate-intensity BFR walking induced the highest cardio-respiratory and perceptual responses compared to other walking sessions. However, jogging elicited higher cardio-respiratory measures than moderate-intensity BFR walking, except for systolic blood pressure. Perceptual measures were higher during moderate-intensity BFR walking compared to jogging. Overall, BFR walking does not seem to provide an equivalent exercise modality for unrestricted jogging in physically active adults.

Summary: This study investigated the influence of blood-flow restriction (BFR) on the distribution of pace, physiological demands, and perceptual responses during self-paced cycling. The results showed that trained cyclists adopted a more even distribution of pace when BFR was applied compared with a negative distribution without restriction. This study provides a useful tool to understand how the distribution of pace is self-regulated.

Summary: This study assessed the reliability of mean concentric bar velocity from 3- to 0-repetitions in reserve (RIR) across different exercises and loads. The study found that the reliability of mean concentric velocity of RIR values varied across sets and exercises, and the velocity of specific RIR values varied across exercises, loads, and sets.
