SUMMARY OBJECTIVE Psychological distress is an important mental health problem among university students. The goal of this study was to determine psychological distress and its associated risk factors among students in the Anhui province. METHODS A cross-sectional study was conducted in a sample of 1304 students. In this study, a self-administered questionnaire consisting of the general demography and General Health Questionnaire (GHQ-12) was completed. Psychological distress was assessed using the GHQ-12-item questionnaire. A dichotomous category split was imposed on the GHQ-12 for the purpose of analysis. A GHQ-12 score of 4 or higher indicated psychological distress. The data were analyzed by SPSS 20.0 system. RESULTS A total of 1304 samples were analyzed in this study. The results indicated that the education level of the father and mother was associated with the students’ psychological distress (P<0.001). A significant association was found between high-intensity exercise and low-intensity exercise and psychological distress. However, no significant difference was identified between gender and psychological distress (P=0.173). CONCLUSION The education level of parents, high-intensity exercise, and low-intensity exercise were associated with psychological distress. Our results suggest that it is indispensable to raise awareness of psychological disorders and its associated risk factors among university students. Further studies are required to develop appropriate interventions for high-risk groups.

We tested the hypothesis that thermal behavior alleviates thermal discomfort and accelerates core temperature recovery following low intensity exercise. Methods: In a 27 ± 0 °C, 48 ± 6% relative humidity environment, 12 healthy subjects (six females) completed 60 min of exercise followed by 90 min of seated recovery on two occasions. Subjects wore a suit top perfusing 34 ± 0 °C water during exercise. In the control trial, this water continually perfused throughout recovery. In the behavior trial, the upper body was maintained thermally comfortable by pressing a button to receive cool water (3 ± 2 °C) perfusing through the top for 2 min per button press. Results: Physiological variables (core temperature, p ≥ 0.18; mean skin temperature, p = 0.99; skin wettedness, p ≥ 0.09; forearm skin blood flow, p = 0.29 and local axilla sweat rate, p = 0.99) did not differ between trials during exercise. Following exercise, mean skin temperature decreased in the behavior trial in the first 10 min (by −0.5 ± 0.7 °C, p < 0.01) and upper body skin temperature was reduced until 70 min into recovery (by 1.8 ± 1.4 °C, p < 0.05). Core temperature recovered to pre-exercise levels 17 ± 31 min faster (p = 0.02) in the behavior trial. There were no differences in skin blood flow or local sweat rate between conditions during recovery (p ≥ 0.05). Whole-body thermal discomfort was reduced (by −0.4 ± 0.5 a.u.) in the behavior trial compared to the control trial within the first 20 min of recovery (p ≤ 0.02). Thermal behavior via upper body cooling resulted in augmented cumulative heat loss within the first 30 min of recovery (Behavior: 288 ± 92 kJ; Control: 160 ± 44 kJ, p = 0.02). Conclusions: Engaging in thermal behavior that results in large reductions in mean skin temperature following exercise accelerates the recovery of core temperature and alleviates thermal discomfort by promoting heat loss.

The goal of this study was to investigate the persistence of cold-induced vasoconstriction following cessation of active skin-surface cooling. This study demonstrates a hysteresis effect that develops between skin temperature and blood perfusion during the cooling and subsequent rewarming period. An Arctic Ice cryotherapy unit (CTU) was applied to the knee region of six healthy subjects for 60 min of active cooling followed by 120 min of passive rewarming. Multiple laser Doppler flowmetry perfusion probes were used to measure skin blood flow (expressed as cutaneous vascular conductance (CVC)). Skin surface cooling produced a significant reduction in CVC (P < 0.001) that persisted throughout the duration of the rewarming period. In addition, there was a hysteresis effect between CVC and skin temperature during the cooling and subsequent rewarming cycle (P < 0.01). Mixed model regression (MMR) showed a significant difference in the slopes of the CVC–skin temperature curves during cooling and rewarming (P < 0.001). Piecewise regression was used to investigate the temperature thresholds for acceleration of CVC during the cooling and rewarming periods. The two thresholds were shown to be significantly different (P = 0.003). The results show that localized cooling causes significant vasoconstriction that continues beyond the active cooling period despite skin temperatures returning toward baseline values. The significant and persistent reduction in skin perfusion may contribute to nonfreezing cold injury (NFCI) associated with cryotherapy.

The importance of supplements used with exercise is increasing day by day. In this study, it was aimed to evaluate the effects of creatine monohydrate (CrM) supplementation with different intensities of exercise on oxidative stress through dynamic thiol disulfide homeostasis. Fourty two BALB/c mice were used and randomly divided into 6 groups; control (C), low-intensity exercise (LIE), high-intensity exercise (HIE), C+CrM (4% of daily diet), LIE+CrM, and HIE+CrM groups. Exercise groups were performed low-intensity (8m/min/30min/day) and high-intensity (24m/min/30min/day) exercise on a mouse treadmill for 8 weeks. At the end of the experimental period, the thiol disulfide homeostasis levels analyzed by using a new automated measurement technique. When the native thiol and total thiol values were examined the difference between the groups was statistically significant (respectively, p=0.029, p=0,035). Creatine intake with exercise decreased native thiol and total thiol levels. However, serum disulfide levels were lower in LIE+CrM compared to other study groups, but there was no statistically significant difference. It is thought that creatine supplementation with exercise reduces the thiol-disulfide homeostasis burden of the organism, and that after the depletion of creatine stores, the sustainability of oxidant-antioxidant homeostasis can be extended, thus prolonging the duration of antioxidant resistance.

Background The diagnosis of fibromyalgia syndrome (FMS) syndrome is often complicated and relies on diagnostic criteria based mostly on the symptoms reported by patients. Implementing objective complementary tests would be desirable to better characterize this population. Objective The purpose of this cross-sectional study was to compare the skin temperature at rest using thermography in women with FMS and healthy women. Methods Eighty-six women with FMS and 92 healthy controls volunteered to participate. The temperature of all participants was measured by infra-red thermography, registering the skin surface temperature (minimum, maximum and average) at rest in different areas: neck, upper and lower back, chest, knees and elbows. In order to analyze the differences in the skin temperature between groups, inferential analyses of the data were performed using Mann-Whitney U test. Results The results showed no significant difference in skin temperature between groups in the neck, upper back, chest and elbows (p>0.05). The lower back and knees areas showed significant differences between groups (p<0.05), although these differences did not reach a minimum of clinically detectable change. Conclusions Women with fibromyalgia presented no clinically meaningful reduction or difference in skin temperature at rest when compared with a group of healthy women. The infra-red thermography is not an effective supplementary assessment tool in women with fibromyalgia.

Therefore the objective of this study was to examine the differences of calf temperature by infrared thermal imager between on anti-fatigue matt and on the floor without mat. The subjects were instructed to wear short pants. It was measured with bare feet because influence of shoes and socks was to except. Subjects worked during 1 hour on the mat or without mat and next day without mat or on the mat. The order and load of work kept regularly. In this study, there was also a significant difference (p < 0.001) in the calf skin temperature between conditions, and calf temperature was higher when the subjects were standing on the mat than when they were standing on the floor without mat. By providing an elastic surface to stand on, a matt simulates muscle activity in feet and legs promote blood circulation. As a cross-modality evaluation, electromyogram was measured. There was the significant difference in Median Frequency (p < 0.001) and Median Power Frequency (p < 0.05) of EMG between two conditions. Median Frequency and Median Power Frequency showed a tendency to more decrease on the floor.

Background: Cancer-related fatigue (CRF) during chemotherapy and after it and decreased body energy are common problems in patients that do not resolve with sleep and rest. Objectives: This study aimed to assess the effect of combination therapy of low-intensity exercise and slow stroke back massage (SSBM) on physical activity and fatigue intensity of patients undergoing chemotherapy. Methods: This clinical trial study was performed on 92 patients with cancer undergoing chemotherapy who were referred to the oncology wards of Baqhaiee-2 hospital Ahvaz-Iran (2018 - 2020). Patients were randomly divided into two groups. Intervention group patients who received three days a week for four weeks that each session 10 minutes for slow stroke back massage and 15 minutes’ low-intensity exercise. Control group patients who received usual care. Data were collected using a demographic questionnaire, Piper Fatigue Scale (PFS), and International Physical Activity Questionnaire (IPAQ) and then analyzed using SPSS software. Results: The results showed the intensity of fatigue decreased in the experimental group, and there was a statistically significant difference between the two groups (P = 0.05). The trend of physical activity increased in the experimental group; however, there was no statistically significant difference between the two groups (P = 0.68). Conclusions: The combination of low-intensity exercise intervention and slow stroke back massage had a positive effect on fatigue severity but no statistically positive effect on physical activity.

This study examined the effects of daily low-intensity exercise following acute stroke on mass, Type I and II fiber cross-sectional area, and myofibrillar protein content of hind-limb muscles in a rat model. Adult male Sprague-Dawley rats were randomly assigned to 1 of 4 groups (n = 7-9 per group): stroke (occlusion of the right middle cerebral artery [RMCA]), control (sham RMCA procedure), exercise, and stroke-exercise. Beginning 48 hours post-stroke induction/sham operation, rats in the exercise group had 6 sessions of exercise in which they ran on a treadmill at grade 10 for 20 min/day at 10 m/min. At 8 days poststroke, all rats were anesthetized and soleus, plantaris, and gastrocnemius muscles were dissected from both the affected and unaffected sides. After 6 sessions of exercise following acute ischemic stroke, the stroke-exercise group showed the following significant (p < .05) increases compared to the stroke-only group: body weight and dietary intake, muscle weight of affected soleus and both affected and unaffected gastrocnemius muscle, Type I fiber cross-sectional area of affected soleus and both affected and unaffected gastrocnemius muscle, Type II fiber cross-sectional area of the unaffected soleus, both affected and unaffected plantaris and gastrocnemius muscle, Type II fiber distribution of affected gastrocnemius muscle, and myofibrillar protein content of both affected and unaffected soleus muscle. Daily low-intensity exercise following acute stroke attenuates hind-limb muscle atrophy in both affected and unaffected sides. The effects of exercise are more pronounced in the soleus and gastrocnemius as compared to the plantaris muscle.
