AbstractBackground: The purpose of the following research was to find out the influence of imaginary training based on intention implementation on throw effectiveness of young basketball players, both male and female in stressogenic situations. Individual differences (action vs state orientation) between players were also measured in this research.Material/Methods: 76 players (32 females and 44 males) in the cadet category (15-16 years old) from basketball clubs of Gdansk, Gdynia and Sopot took part in this research. In the first stage all players did a throw efficiency test ERPE 05 under two conditions, and their heart rate was measured. Then players were randomly assigned to one of two groups. The first one did imaginary training based on the influence of intention implementation for 10 days, while the other did not. After 10 days ERPE 05 test under two conditions was run again.Results: Test results showed that intention implementation does not influence effectiveness improvement in stressogenic conditions as far as state-oriented players are concerned, but it does lower the physiological cost of physical effort in form of a decreased heart rate.Conclusions: This research proves that visualization training based on implementation instructions does influence young players’ physiology and significantly lowers their heart rate under stressogenic conditions. However useful, visualization techniques used in this research still need other tests and should be applied for a longer period of time to acutely show how they affect young players’ mental preparation

The Relationship

Purpose:To develop and validate an intermittent match-fitness test for water-polo players.Methods:Eight male junior players performed the Water Polo Intermittent Shuttle Test (WIST) twice to assess test reliability. To assess test sensitivity and validity, 104 male and female players from different competition standards and playing positions were tested. Eighteen players performed the WIST 5 times throughout a season to track fitness changes. Twelve players performed the WIST 48 hours before 4 consecutive National League games, and coaches awarded individual match-fitness scores based on game performances to assess the relationship between match fitness and test results. Heart rate (HR) and blood lactate (Lablood) were measured during and after each test, respectively.Results:Test–retest performance values were 216 ± 90 vs 229 ± 96 m (r = .98, P = .0001, coefficient of variation [CV] = 5.4%), peak HR 190 ± 8 vs 192 ± 10 bpm (r = .96, P = .0002, CV = 1.2%), and Lablood 7.0 ± 1.8 vs 6.4 ± 1.6 mmol/L (r = .84, P = .0092, CV = 8.8%). Significant differences were observed among different standards of play (range junior regional females 102 ± 10 m, senior international males 401 ± 30 m) and playing positions (field players 305 ± 154 m, center forwards 255 ± 118, goal keepers 203 ± 135 m). Test performance was lower in the early season (344 ± 118 m) than the remainder of the season (range 459 ± 138 to 550 ± 176 m). WIST performance and match-fitness scores correlated for all field players (r = .57, P = .054) but more highly for field players other than center forwards (r = .83, P = .0027).Conclusions:The WIST is a reliable, sensitive, and valid match-fitness test for water-polo players. It could become a useful tool to assess the effects of different interventions on match fitness.

Traditionally, horse riding has been restricted to men but today equestrian sports are dominated by women. We hypothesised that men and women differ with regard to riding and the response they evoke in their horse. Cortisol and heart rate variability (HRV) were studied in male (n=8) and female riders (n=8) and in horses (n=8) ridden by men and women over a jumping course. Saliva for cortisol analysis was collected, cardiac beat to beat (RR) intervals were recorded and heart rate and HRV variables SDRR (standard deviation of RR interval) and RMSSD (root mean square of successive RR differences) calculated. In another experiment, saddle pressure was compared between male and female riders (n=5 each). Cortisol did not differ between male and female riders and increased in horses (P<0.001) irrespective of the sex of the rider. Heart rate in riders increased from walk to jumping (P<0.001) while HRV decreased (P<0.001) to the same extent in men and women. In horses, heart rate increased (P<0.001) and SDRR and RMSSD decreased during walk and remained low at trot and canter (P<0.001) irrespective of the riders’ sex. In trot (P<0.05) and canter (P<0.01) saddle pressure was slightly lower in female versus male riders. This is due to weight differences and not to a different seat. In conclusion, no fundamental differences existed in the physical effort, stress response and seat between male and female riders and in the response of horses to men and women.

The purpose of this study is to examine the burnout levels of basketball players in terms of gender, age and experience. A total of 270 (124 female and 146 male) basketball players (age mean x = 23.07 ± 1.28 years) participated in the study. Maslach’s Burnout Inventory was developed by Maslach and Jackson (1981) and adapted to Turkish by Ergin (1992) was used to measure the burnout levels of basketball players for collecting data. The data were analyzed with SPSS program. The Cronbach's alpha coefficient was calculated to test the internal consistency of the scale. The Mann-Whitney U test was used for paired group comparisons. The Kruskal Wallis H test was used for the multiple group comparisons. When Mann Whitney U test results were examined, Emotional Exhaustion (p = .063, p> .05), Depersonalization (p = .498, p> .05) and Personal Accomplishment (p = .599, p> .05), there was no significant difference between male and female basketball players according to gender. According to Kruskall Wallis H test results, the variables of emotional exhaustion (p = .162, p> .05), Depersonalization (p=.319, p>.05) and Personal Accomplishment (p = .284, p> .05) no significant difference was observed. According to Kruskall Wallis H test results, there was no significant difference in Personal Accomplishment (p = .674, p> .05) sub-dimensions according to experience variable. However, significant differences were found in the subscales of Emotional Exhaustion (p = .002, p <.05) and Depersonalization (p = .033, p <.05) compared to the experience variable. As a result, the level of burnout is important for the experience of basketball players.

Research background and hypothesis. Replete schedule of competitions and intense training are features of contemporary team sports. Athletes, especially the most involved ones, may not have enough time to recover. As a consequence, aggregated fatigue can manifest in some undesirable form and affect athlete’s performance and health.Research aim. The aim of this study was to evaluate the changes in heart rate recovery (HRR) and investigate possible relations with sport-specifi c measures of effi cacy in professional basketball players during competition season.Research methods. Eight male high-level basketball players (mean ± SD, body mass, 97.3 ± 11.33 kg; height 2.02 ± 0.067 m, and age 23 ± 3.12 years) were investigated. The same basketball specifi c exercise was replicated several times from September till April during the practice sessions in order to assess the personal trends of HRR. Heart rate monitoring was performed using POLAR TEAM SYSTEM. Investigated athletes were ranked retrospectively according to the total amount of minutes played and the coeffi cients of effi cacy. Research results. There were signifi cant differences in the trends of HRR between the investigated players. The most effective players showed decreasing trends of HRR in all cases of ranking.Discussion and conclusions. Research fi ndings have shown that the quality of heart rate recovery differs between basketball players of the same team and could be associated with sport-specifi c effi cacy and competition playing time.Keywords: adaptation, autonomic control, monitoring training.

Abstract Introduction Pathophysiologic responses to viral respiratory challenges such as SARS-CoV-2 may affect sleep duration, quality and concomitant cardiorespiratory function. Unobtrusive and ecologically valid methods to monitor longitudinal sleep metrics may therefore have practical value for surveillance and monitoring of infectious illnesses. We leveraged sleep metrics from Sleep Number 360 smart bed users to build a COVID-19 predictive model. Methods An IRB approved survey was presented to opting-in users from August to November 2020. COVID-19 test results were reported by 2003/6878 respondents (116 positive; 1887 negative). From the positive group, data from 82 responders (44.7±11.3 yrs.) who reported the date of symptom onset were used. From the negative group, data from 1519 responders (48.4±12.9 yrs.) who reported testing dates were used. Sleep duration, sleep quality, restful sleep duration, time to fall asleep, respiration rate, heart rate, and motion level were obtained from ballistocardiography signals stored in the cloud. Data from January to October 2020 were considered. The predictive model consists of two levels: 1) the daily probability of staying healthy calculated by logistic regression and 2) a continuous density Hidden Markov Model to refine the daily prediction considering the past decision history. Results With respect to their baseline, significant increases in sleep duration, average breathing rate, average heart rate and decrease in sleep quality were associated with symptom exacerbation in COVID-19 positive respondents. In COVID-19 negative respondents, no significant sleep or cardiorespiratory metrics were observed. Evaluation of the predictive model resulted in cross-validated area under the receiving-operator curve (AUC) estimate of 0.84±0.09 which is similar to values reported for wearable-sensors. Considering additional days to confirm prediction improved the AUC estimate to 0.93±0.05. Conclusion The results obtained on the smart bed user population suggest that unobtrusive sleep metrics may offer rich information to predict and track the development of symptoms in individuals infected with COVID-19.

Purpose: To compare weekly training and game demands according to playing position in basketball players. Methods: A longitudinal, observational study was adopted. Semiprofessional, male basketball players categorized as backcourt (guards; n = 4) and frontcourt players (forwards/centers; n = 4) had their weekly workloads monitored across an entire season. External workload was determined using microsensors and included PlayerLoad™ (PL) and inertial movement analysis variables. Internal workload was determined using heart rate to calculate absolute and relative summated-heart-rate-zones workload and rating of perceived exertion (RPE) to calculate session-RPE workload. Comparisons between weekly training and game demands were made using linear mixed models and effect sizes in each positional group. Results: In backcourt players, higher relative PL (P = .04, very large) and relative summated-heart-rate-zones workload (P = .007, very large) were evident during training, while greater session-RPE workload (P = .001, very large) was apparent during games. In frontcourt players, greater PL (P < .001, very large), relative PL (P = .019, very large), peak PL intensities (P < .001, moderate), high-intensity inertial movement analysis events (P = .002, very large), total inertial movement analysis events (P < .001, very large), summated-heart-rate-zones workload (P < .001, very large), RPE (P < .001, very large), and session-RPE workload (P < .001, very large) were evident during games. Conclusions: Backcourt players experienced similar demands between training and games across several variables, with higher average workload intensities during training. Frontcourt players experienced greater demands across all variables during games than training. These findings emphasize the need for position-specific preparation strategies leading into games in basketball teams.

Abstract Introduction: Therapy choice and its progression for patients with Chronic Obstructive Pulmonary Disease (COPD) should be based on their symptoms and clinical condition according to reports of dyspnea and fatigue. Therefore patient-reported scales have presented a key role during the communication with the patient. Objective: To verify if patients with COPD prefer the Modified Borg Scale (MBS), Visual Analogue Scale (VAS), Glasses Scale (GS), Faces Scale (FS) or Ratings of Perceived Exertion (RPE) during the six-minute walk test(6MWT), and to compare and correlate the scales with each other, with peripheral oxygen saturation (SpO2) and heart rate (HR). Methods: 28 patients with COPD (50% had mild to moderate COPD and 50% had severe to very severe) were evaluated by a respiratory and cognitive assessment. Additionally, they performed the 6MWT, in which the scales were applied simultaneously (random order) and patients reported their preference in the end of the test. Results: 57% of patients were illiterate or presented incomplete primary education and most of them (67%) chose the FS or GS. Significant positive correlations were observed between instruments for both dyspnea and fatigue in the end of the 6MWT, which the strongest was between MBS and FS (r = 0.95). Nevertheless, there was no correlation between the scales and SpO2 and HR. Conclusion: As the majority of patients preferred pictured to numerical scales we suggest their use as a resource for therapeutic evaluation; MBS might be replace by FS, even though they have different scores and not scaled proportionally. However, this change must be carefully considered because there is the risk of dubious interpretation.
