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 Background The prevalence of chronotropic incompetence (CI) in heart failure (HF) population is high and negatively impacts prognosis. In HF patients with an implanted cardiac resynchronisation therapy (CRT) device and severe CI, the effect of rate adaptive pacing on patient outcomes is unclear. Closed loop stimulation (CLS) based on cardiac impedance measurement may be an optimal method of heart rate adaptation according to metabolic need in HF patients with severe CI. Purpose This is the first study evaluating the effect of CLS on the established prognostic parameters assessed by the cardio-pulmonary exercise (CPX) testing and on quality of life (QoL) of the patients. Methods A randomised, controlled, double-blind and crossover pilot study has been performed in CRT patients with severe CI defined as the inability to achieve 70% of the age-predicted maximum heart rate (APMHR). After baseline assessment, patients were randomised to either DDD-CLS pacing (group 1) or DDD pacing at 40 bpm (group 2) for a 1-month period, followed by crossover for another month. At baseline and at 1- and 2-month follow-ups, a CPX was performed and QoL was assessed using the EQ-5D-5L questionnaire. The main endpoints were the effect of CLS on ventilatory efficiency (VE) slope (evaluated by an independent CPX expert), the responder rate defined as an improvement (decrease) of the VE slope by at least 5%, percentage of maximal predicted heart rate reserve (HRR) achieved, and QoL. Results Of the 36 patients enrolled in the study, 20 fulfilled the criterion for severe CI and entered the study follow-up (mean age 68.9±7.4 years, 70% men, LVEF=41.8±9.3%, 40%/60% NYHA class II/III). Full baseline and follow-up datasets were obtained in 17 patients. The mean VE slope and HRR at baseline were 34.4±4.4 and 49.6±23.8%, respectively, in group 1 (n=7) and 34.5±12.2 and 54.2±16.1% in group 2 (n=10). After completing the 2-month CPX, the mean difference between DDD-CLS and DDD-40 modes was −2.4±8.3 (group 1) and −1.2±3.5 (group 2) for VE slope, and 17.1±15.5% (group 1) and 8.7±18.8% (group 2) for HRR. Altogether, VE slope improved by −1.8±2.95 (p=0.31) in DDD-CLS versus DDD-40, and HRR improved by 12.9±8.8% (p=0.01). The VE slope decreased by ≥5% in 47% of patients (“responders to CLS”). The mean difference in the QoL between DDD-CLS and DDD-40 was 0.16±0.25 in group 1 and −0.01±0.05 in group 2, resulting in an overall increase by 0.08±0.08 in the DDD-CLS mode (p=0.13). Conclusion First results of the evaluation of the effectiveness of CLS in CRT patients with severe CI revealed that CLS generated an overall positive effect on well-established surrogate parameters for prognosis. About one half of the patients showed CLS response in terms of improved VE slope. In addition, CLS improved quality of life. Further clinical research is needed to identify predictors that can increase the responder rate and to confirm improvement in clinical outcomes.

Abstract INTRODUCTION This study presents the first steps and results towards the development of a system for predicting the quality of surgical performance and workload in laparoscopic training. MATERIAL AND METHODS Surgeons wore a smartwatch which recorded their heart rate and hand motion during each laparoscopic procedure. Data was then correlated with both the Surgery Task Load Index (SURG-TLX) subjective questionnaire and the Global Operational Assessment of Laparoscopic Skills (GOALS) objective evaluation tool. Statistical analysis was conducted in order to study the relationship between parameters and to compare the results according to the surgeons’ level of experience. RESULTS Nine laparoscopic surgeons participated in this study, five gynecologists and four digestive surgeons. Gynecological surgeons showed a positive correlation between their level of experience, heart rate, hand motion, and GOALS score, except for bimanual dexterity. The reduction in the variability of hand accelerations led to improved tissue handling. Digestive surgeons showed a negative correlation between their level of experience and the reported temporal demand and complexity of the procedure. Novice digestive surgeons reported increased workload during surgery, mainly in mental, physical, and temporal workload. In both surgical specialties, it was observed that reduction in surgical workload was associated with improved GOALS score. CONCLUSIONS Preliminary results showed that bimanual dexterity is independent of the experience of gynecological surgeons. During laparoscopic surgical procedures, reduced variability in hand accelerations leads to better tissue manipulation. In addition, in gynecological and upper gastrointestinal procedures, reduced surgical workload is associated with improved surgical performance.

Resting Heart Rate

Purpose: Resting heart rate (HR), health related quality of life (HQoL) and NYHA functional capacity are referred as important determinants of prognosis and targets of therapy in heart failure (HF). REALITY HF (Resting Heart Rate and Real Life Treatment Modality in Outpatients with Left Ventricular Systolic Dysfunction) study data were analyzed for the evaluation of any relationship of resting HR with HQoL assessed by Kansas City Cardiomyopathy Questionnaire (KCCQ) and NYHA functional class. Methods: REALITY HF was a multicenter, prospective registry designed to evaluate HF patients’ characteristics and effects of treatment modalities on resting HR and enrolled 1057 patients (age 61±12 years) with LVEF <40%. 781 (74%) patients in sinus rhythm were included in this analysis. Patients were classified into 4 groups according to the quartiles of HR: Q1:<68 bpm (n=234), Q2:69-75 bpm (n=189), Q3:76-87 bpm (n=194) and Q4:>87 bpm (n=164). KCCQ was completed in a random sample of 320 (Q1:n=27, Q2:n=99, Q3:n=125, Q4:n=69) patients, in which higher scores show better patient’s health status. Results: During enrollment, 82% of patients were receiving ≥2 drugs including ACE[[Unable to Display Character: &#304;]]/ARB, beta blocker, aldosterone blocker, diuretic or digoxin. Resting HR was 76±14 bpm and 68% of patients had a resting HR ≥70 bpm. KCCQ overall summary score (OSC) was found to be 75.7±13.2 in those in Q1, 65.5±20.8 in Q2, 64.4±20.6 in Q3 and 58.3±21.2 in Q4 (p=0.004) and KCCQ clinical summary score (CSS) was 80.4±15.7 in those in Q1, 70.0±22.4 in Q2, 69.9±21.9 in Q3 and 63.8±23.3 in Q4 (p=0.016). Also, there was a significant negative correlation between resting HR and OSC (p=0.008) or CSS (p=0.031). The distribution of NYHA-I patients for Q1, Q2, Q3 and Q4 were 40.7%, 22.8%, 23.8% and 12.7%, NYHA-II patients-30.8%, 23.1%, 27.2% and 18.9%, NYHA-III patients-21.2%, 23.9%, 24.3% and 30.6% and NYHA-IV patients-22.7%, 34.1%, 22.7% and 20.5%, respectively (p<0.001). Also, resting HR were found to gradually and significantly increase across NYHA categories (72.8±12 bpm in NYHA-I, 76.1±13 bpm in NYHA-II, 80.2±15 bpm in NYHA-III and 78.9±16 bpm in NYHA-IV, p<0.001). Conclusions: These results suggest that elevated resting HR in HF patients is associated with impaired HQoL and worse NYHA functional capacity.

Background: Adjuvant used with local anaesthetic agent in caudal is more effective for post operative analgesia in children . Aim and objective: To find out the duration and quality of caudal analgesia in children undergoing genitourinary surgery by combination of bupivacaine and midazolam. Methods: A total number of sixty patients ASA grade I&II were selected randomly as per inclusion & exclusion criteria in two groups. Thirty in each group. In group A, caudal block was given by bupivacainemidazolam mixture and in group B, caudal block was given by bupivacaine in lateral decubitus position, just after completion of surgery before reversed from GA. In post operative period arterial blood pressure, heart rate, and duration of analgesia were recorded. Results: There was no significant difference between the groups of blood pressure, heart rate, and pain score up to 30 min but after one hour of post operative period pain scores were significant(p<0.05). Conclusion: Midazolam improves the duration and quality of analgesic effect of bupivacaine. DOI: http://dx.doi.org/10.3329/jbsa.v23i1.18152 Journal of BSA, 2010; 23(1): 8-13
