Face Cooling

The aim of this study was to test the effect of face cooling with cold water (1.2 ± 0.7°C) vs. face cooling with neutral water (28.0 ± 3.0°C) during high-intensity swimming training on both the core temperature (Tco) and thermal perceptions in internationally ranked long-distance swimmers (5 men’s and 3 women’s) during 2 randomized swimming sessions. After a standardized warm-up of 1,200 m, the athletes performed a standardized training session that consisted of 2,000 m (5 × 400 m; start every 5’15”) at a best velocity then 600 m of aerobic work. Heart rate (HR) was continuously monitored during 5 × 400 m, whereas Tco, thermal comfort (TC), and thermal sensation (TS) were measured before and after each 400 m. Before and after each 400 m, the swimmers were asked to flow 200 mL of cold water (1.2°C) or neutral (22°C) water packaged in standardized bottles on their face. The swimmers were asked don’t drink during exercise. The velocity was significantly different between cold water and neutral water (p < 0.004 – 71.58 m.min–1 ± 2.32 and 70.52 m.min–1 ± 1.73, respectively). The Tco was increased by ±0.5°C at race pace, under both face cooling conditions with no significant difference. No significant changes were noted in mean HR (i.e., 115 ± 9 and 114 ± 15 bpm for NW and CW, respectively). TC was higher with Cold Cooling than Neutral Cooling and TS was lower with Cold cooling compared with Neutral cooling. The changes in perceptual parameters caused by face cooling with cold water reflect the psychological impact on the physical parameters. The mean velocity was less important with face cooling whereas the heat rate and Tco were the same in the both conditions. The mechanism leading to these results seems to involve brain integration of signals from physiological and psychological sources.

The authors tested the effect of cold water ingestion during high-intensity training in the morning vs the evening on both core temperature (TC) and thermal perceptions of internationally ranked long-distance swimmers during a training period in a tropical climate. Nine internationally ranked long-distance swimmers (5 men and 4 women) performed 4 randomized training sessions (2 in the evening and 2 in the morning) with 2 randomized beverages with different temperatures for 3 consecutive days. After a standardized warm-up of 1000 m, the subjects performed a standardized training session that consisted of 10 × 100 m (start every 1′20″) at a fixed velocity. The swimmers were then followed for the next 3000 m of the training schedule. Heart rate (HR) was continuously monitored during the 10 × 100 m, whereas TC, thermal comfort, and thermal sensation (TS) were measured before and after each 1000-m session. Before and after each 1000 m, the swimmers were asked to drink 190 mL of neutral (26.5 ± 2.5°C) or cold (1.3 ± 0.3°C) water packaged in standardized bottles. Results demonstrated that cold water ingestion induced a significant effect on TC, with a pronounced decrease in the evening, resulting in significantly lower mean TC and lower mean delta TC in evening cold (EC) than in evening neutral (EN), concomitant with significantly lower TS in EC than in EN and a significant effect on exercise HR. Moreover, although TC increased significantly with time in MN, MC, and EN, TC was stabilized during exercise in EC. To conclude, we demonstrate that a cold beverage had a significant effect on TC, TS, and HR during training in high-level swimmers in a tropical climate, especially during evening training.

The aim of this research paper was to examine the voice quality of sports coaches using the objective (acoustic) method. A total of 28 sports coaches (mean age 28.58, SD=5.08), from the City of Zagreb participated in this research. Recordings of the phonation of the vowel /a/ before and after one training session were obtained and analyzed using the PRAAT Program. Mean, minimal and maximal values of fundamental frequency, shimmer, jitter and harmonics-to-noise ratio were observed. The statistical analyses showed no statistically significant difference in acoustic voice quality of male and female coaches before and after the training session, or between male and female coaches. However, intra-individual differences among participants were observed, which may be significant in terms of their potential to affect the quality of their voices in the future.

Based on basic health research in 2007, chronic disease is still in the top ten of the most occurred in Indonesia. From the health profile  of Bali province  in  2014, it  shown  that the chronic disease is still in the top ten of most visit in the hospitals, both in inpatient  and outpatient. Bali province  is one of province with high density population.  The role of paramedic  in curing the chronic disease can be in the form of primary,  secondary,  or tertiary prevention.  Primary prevention for the chronic disease is conducted  through modifying  the risk factors via life style's  change. The healthy phone-call  method  is based on the culture of Balinese  community,  in which they are very consumptive  to use the communication  technology,  namely phone.  Individual who has been screened to have risks of having the contagious disease is monitored by paramedics  and get the needed medical services through  long distance  communication.  Many  controls  are needed  namely  regular  exercise,  knowledge  of healthy  food,  stress management. Telenursing method has several advantage, i.e., effective and efficient, lowering the curing cost of chronic diseases, and increasing the degree of the community health.  The aim of this study was to know the effect of healthy phone-call  to control the  risk  factor  of chronic  disease  in Bali.    The  research  method  used  was  quasy  experimental  to  analyse  the  difference  in knowledge,  attitude,  and behavior  of preventing  chronic disease  from nutrition  management  aspect in  individual  who has been screened to have chronic disease's  risk before and after the healthy phone-call  treatment.   This study was conducted  in working area of the Centre of Community Health III South Denpasar.  Individual with chronic disease's risk was given intervention namely phone-call  and short message three times per week for 3  weeks.  The results of this study demonstrated  a significant difference in chronic disease preventing  behavior based on nutrition management  aspect before and after given phone-call  on 30  respondents (p = 0,000).   A healthy phone-call  can be used  as one of chronic  disease primary prevention  method  through  knowledge  and information addition  in individual with chronic disease's risk. Chronic disease can be applied  in nursing nurturing treatment  in preventing and promoting efforts both in community and in hospital.

The cold pressor test (CTP) as a diagnostic method of the circulatory system reactivity may be a basis for the qualification for thermal stimulation therapy. The aim of the work was a thermovisual assessment of the reaction to the Hines and Brown cold pressor test. A group of 30 healthy men in the age of 23.5 ± 0.8 years were examined. The average weight of the examinees was 78.4 ± 9.2 kg, their height 180.7 ± 5.9 cms, and BMI 23.9 ± 2.2 kg/m2. A thermovisual picture of a tested and not tested hand of all the subjects was taken before and after the cold pressor test. Under the influence of cold water the surface temperature of a tested hand has decreased in a statistically significant way by 8.3°C on average, which is 29% of the temperature before the test, whilst the temperature of an untested hand dropped by 0.67°C. The decreases of temperature were not even and there was a statistically significant difference between the dorsal and palmar side of the hand. The correlation between the changes of systolic blood pressure and the hand surface temperature before and after CTP was observed.

ABSTRACT Introduction Dehydration has been described as one of the main factors of reduced performance in combat sports activities, leading to death in extreme cases. Objective To investigate the pre-training hydration status and changes in fluid homeostasis during two taekwondo training sessions. Methods Eighteen male college athletes (age 22.6 ± 3.37 years) were assessed. The study design aimed to reproduce the conditions of a 90-minute taekwondo training session, divided into three stages: a) warm-up exercises (20 min); b) poomsae (30 min) and c) technical training (40 min). The athletes had ad libitum water intake during training. To assess the hydration status we considered body mass (BM), the amount of liquid consumed and urine output, which enabled us to establish absolute and relative fluid loss in kg and percentage as well as the sweating rate. We also considered urine specific gravity (USG), urine color (U-COL), and subjective sensation of thirst (Sthirst) before and after the training session. Pre- and post-training results were compared separately in each session and between sessions. Results There was a significant difference (P<0.05) in pre-training BM between the two days of training. There was a significant difference (P<0.05) in the final BM on both days of the experiment. Most subjects had relative dehydration below 2%. A significant difference (P<0.05) was recorded pre and post training for U-COL and Sthirst, with the highest rates obtained at the end of each session. Participants always started training at a low dehydration status (USG >1,020g.ml-1). Conclusions The athletes tended to start the training sessions in dehydration status, which increases over the course of the training. Ad libitum water intake was not sufficient to balance fluid loss. Changes in fluid levels between sessions were similar.

Background: Regardless of the sport discipline, the rules of prophylaxis, coaching methods and experience, injuries and contusions in athletes occur. They are inevitable, and when they eventually appear, a comprehensive therapy should be applied to avoid complications and further injuries.Material and methods: A female runner was given a classical massage, before and after the training session each of 10 minutes and, additionally, two sessions of 45-minute-tensegrity massage. Two diferent confgurations were worked out (I and II) because only selected connective tissues were intensively sensitive to compression. Results: After the classical massage the decrease in pain of fbular muscles (peroneus longus and brevis) was achieved, however, after the tensegrity massage the reduction of pain in inguinale ligaments was additionally observed. The massage of the tissues being in direct and indirect contact with the injured area resulted in complete pain elimination.Conclusions: Tensegrity massage can be used in the cases of connective tissue injuries and other mild injuries which are found in athletes. The choice of the type of the massage always depends on current symptoms and needs of the athletes. The therapy ought to be completed with the education on the preventive activities which athletes should follow. Keywords: classical and tensegrity massage, injury, pain

This study investigated the relationship between mindfulness training (a nonjudgmental attentional training technique) and flow experiences in athletes. Participants were 13 university athletes (M = 21 years), assigned either to a control group or an experimental group. Flow experiences were assessed before and after the intervention. ANOVA (group x time) of global scores on the Flow State Scale-2 (FSS-2; Jackson & Eklund, 2004) showed a significant interaction (F = 11.49, p < .05). Follow-up t tests indicated no significant difference (p > .05) between the experimental and control groups’ FSS-2 global scores at the baseline training session, but a large difference (p < .05, d = 1.66) at a follow-up training session. Significant interaction effects were also observed for FSS-2 subscales scores for the flow dimensions of “Clear Goals” (F =18.73, p < .05) and “Sense of Control” (F = 14.61, p < .05). Following an evaluation of the strengths and weaknesses of this study, the theoretical significance of the results is assessed and the promise for the application of mindfulness training in performance enhancement is discussed.

Running is one of the most accessible physical activities and long-distance running has attracted extensive attention in the past several years. While the incidence of running injuries, especially to the lower extremities, has increased. The objective of this study was to investigate the differences in ground reaction forces (GRF) and kinematic param between long-distance runners before and after long-distance running on treadmill (TM), asphalt road (AR), and plastic track (PT). Eight-camera Vicon motion analysis system was used to measure the hip, knee and ankle motion param of 10 healthy male subjects at a speed of 2.8 ± 0.2m/s. The hip, knee and ankle kinematics and the relationship of joint angles of lower limbs in the sagittal plane, coronal plane and transversal plane were analyzed. Ground reaction force (GRF) was collected using an AMTI force platform. The results showed that there were no significant differences in GRF and average loading rate (VALR). There was no significant difference in the range of motion (ROM) of ankle and hip after long-distance running on three surfaces compared to pre-test. Compared with stance-period of pre-test, the stance-period of AR and PT were significantly longer. Post hoc analyses exhibited the stance-period of AR and PT were longer than TM. In conclusion, runners can adjust different joints angles to maintain a similar GRF during long-distance running on different sports surfaces.

This study aimed to investigate the muscle fatigue and self-perceived exertion level on violin players before and after a training session. Fourteen professional violin players volunteered in this study. Surface electromyography (EMG) was used to record the fatigue level of the upper trapezius muscles before and after a training session. Medium Frequency (MF) of the EMG signals was used to document the fatigue rate of this muscle. Regression analysis and paired sample t-tests revealed no significant difference in the slopes of MF on both sides of trapezius muscle, before and after the training sessions. However, the Borg Scale ratings of perceived exertion revealed significant increase in fatigue level (p=0.003) after the training session. The disparity in the subjective perception with the objective findings indicated that the violists' self-perceived exertion arises from multiple sources. The high prevalence of playing-related musculoskeletal complaints (79%) in this group of players warrants further ergonomic investigation of possible work-related risk factors.
