RESUMO

BACKGROUND: Subjects suffering from psychiatric disorders are frequently hospitalized due to medical comorbidities. In the present study, we analyzed consultation-liaison psychiatry (CLP) activity in a General Hospital, describing the sociodemographic, diagnostic, and therapeutic characteristics of the evaluated subjects, as well as reasons for consultation requests. SUBJECTS AND METHODS: Data concerning psychiatric consultation performed at the Perugia General Hospital during a 1-year period (01/06/2022-20/06/2023) were collected and analyzed by means of descriptive statistics. RESULTS: A total of 707 psychiatric consultations were performed. The primary reason that led to psychiatric consultations was psychomotor agitation. 85 (18.5%) patients attempted suicide; the most frequent modality was the assumption of drugs at non-therapeutic doses. The 72% of the sample (n=509) presented a clear-cut medical comorbidity. In most cases, subjects were referred to Community Mental Health and Addiction services (n=22, 32.4%). CONCLUSIONS: CLP plays a crucial role in the perspective of the overall well-being of hospitalized subjects, but also for the overall management of complex cases. Despite this, a homogeneous approach with standardized guidelines is needed in this field.

RESUMO

Purpose: The purpose of this study was to look for a new, simple, and fast method of assessing and monitoring indoor race performance and to assess the relationship between 20 s, 60 s, and 2000 m indoor rowing performances of youth rowers to evaluate their anaerobic profile. Methods: For three consecutive days, 17 young able-bodied male rowers (15.8 ± 2.0 years), performed three tests (20 s, 60 s, and 2000 m) on a rowing ergometer. Mean power (W20, W60, and W2000) and 2000 m time (t2000) were considered for the analysis. In addition, 14 athletes (15-18 years) performed a 20 s, 60 s, and 2000 m tests and used this as a control group. To define the anaerobic profile of the athletes, W20 and W60 were normalized as percentages of W2000. Associations between variables were determined by means of the Pearson correlation coefficient (r). Results: Mean power decreased with increasing test duration (W20 = 525.1 ± 113.7 W; W60 = 476.1 ± 91.0 W; W2000=312.9 ± 56.0 W) and negative correlations emerged between t2000 (418.5 ± 23.1 s) and W20 (r = -0.952, p < 0.0001) and W60 (r = -0.930, p < 0.0001). Conclusion: These findings indicate that W20 and W60 are significant predictors of 2000 m rowing ergometer performances. Furthermore, normalized W20 and W60 can be used to evaluate athletes and as a reference for planning anaerobic training sessions, on a rowing ergometer.

RESUMO

AIM & METHODS: Extreme endurance exercise provides a valuable research model for understanding the adaptive metabolic response of older and younger individuals to intense physical activity. Here, we compare a wide range of metabolic and physiologic parameters in two cohorts of seven trained men, age 30 ± 5 years or age 65 ± 6 years, before and after the participants travelled ≈3000 km by bicycle over 15 days. RESULTS: Over the 15-day exercise intervention, participants lost 2-3 kg fat mass with no significant change in body weight. V̇O2 max did not change in younger cyclists, but decreased (p = 0.06) in the older cohort. The resting plasma FFA concentration decreased markedly in both groups, and plasma glucose increased in the younger group. In the older cohort, plasma LDL-cholesterol and plasma triglyceride decreased. In skeletal muscle, fat transporters CD36 and FABPm remained unchanged. The glucose handling proteins GLUT4 and SNAP23 increased in both groups. Mitochondrial ROS production decreased in both groups, and ADP sensitivity increased in skeletal muscle in the older but not in the younger cohort. CONCLUSION: In summary, these data suggest that older but not younger individuals experience a negative adaptive response affecting cardiovascular function in response to extreme endurance exercise, while a positive response to the same exercise intervention is observed in peripheral tissues in younger and older men. The results also suggest that the adaptive thresholds differ in younger and old men, and this difference primarily affects central cardiovascular functions in older men after extreme endurance exercise.

RESUMO

BACKGROUND: The aim of this study was to investigate if the supplementation with Opuntia ficus-indica (OFI) juice may affect plasma redox balance and heart rate variability (HRV) parameters following a maximal effort test, in young physically active women. METHODS: A randomized, double blind, placebo controlled and crossover study comprising eight women (23.25 ± 2.95 years, 54.13 ± 9.05 kg, 157.75 ± 0.66 cm and BMI of 21.69 ± 0.66 kg/m2) was carried out. A juice containing OFI diluted in water and a Placebo solution were supplied (170 ml; OFI = 50 ml of OFI juice + 120 ml of water; Placebo = 170 ml beverage without Vitamin C and indicaxanthin). Participants consumed the OFI juice or Placebo beverage every day for 3 days, before performing a maximal cycle ergometer test, and for 2 consecutive days after the test. Plasma hydroperoxides and total antioxidant capacity (PAT), Skin Carotenoid Score (SCS) and HRV variables (LF, HF, LF/HF and rMSSD) were recorded at different time points. RESULTS: The OFI group showed significantly lower levels of hydroperoxides compared to the Placebo group in pre-test, post-test and 48-h post-test. PAT values of the OFI group significantly increased compared to those of the Placebo group in pre-test and 48-h post-test. SCS did not differ between groups. LF was significantly lower in the OFI group 24-h after the end of the test, whereas rMSSD was significantly higher in the OFI group 48-h post-test. CONCLUSION: OFI supplementation decreased the oxidative stress induced by intense exercise and improved autonomic balance in physically active women.

RESUMO

Many studies reported various relationships between 2000-m rowing performance and anthropometric as well as metabolic variables, however, little is known about 60-s mean power in elite youth athletes. The aim of this study was to develop different regression models to predict 2000-m rowing indoor performance time (t2000) using anthropometric variables, maximal oxygen uptake (VO2max) and mean power established during a 60-s all-out test (W60) in national elite youth rowers. Fifteen youth male Italian rowers (age: 15.7 ± 2.0 years; body height: 176.0 ± 8.0 cm; body mass: 71.2 ± 10.0 kg) performed an incremental maximal test, a 60-s all-out test and a 2000-m race simulation using a Concept2 rowing ergometer to assess VO2max, W60 and t2000, respectively. The relationships of all variables with t2000 were investigated through Pearson's correlation. Multiple regression analyses were used to verify the best prediction model of 2000-m indoor rowing performance. The reliability of these models was expressed by R2 and the standard error of estimate. The results showed that t2000 was significantly correlated with all the examined variables, except for VO2max/body mass and age, and exhibited the significantly highest relationship with W60 (r = -0.943). The combination of anthropometric, VO2max and W60 variables was found to be the most reliable equation to predict t2000 (R2 = 0.94, SEE = 6.4). W60 measure should be considered when monitoring the rower's capability to perform high-intensity phases, important during the race's fast start and end. Not requiring expensive equipment and long duration, a 60-s all-out test could be considered a valuable tool for predicting 2000-m performance of elite youth rowers.

RESUMO

Cerasola, D, Cataldo, A, Bellafiore, M, Traina, M, Palma, A, Bianco, A, and Capranica, L. Race profiles of rowers during the 2014 Youth Olympic Games. J Strength Cond Res 32(7): 2055-2060, 2018-Among the different factors affecting the outcome of elite rowing competitions, pacing strategy plays a relevant role. The purpose of this study was to analyze the race profiles of youth athletes competing at the 2014 Youth Olympic Games over a distance of 1,000 m. According to the competition outcome of sculling and sweep events, 96 youth (17-18 years) rowers (48 male and 48 female) were divided into winner (W), not winner (NW), qualified (Q), and not-qualified (NQ) athletes. The time during the 1,000-m race distance was considered at 0-500 m (T1) and 500-1000 m (T2). The average speed of T1 and T2 were normalized in relation to the average speed of the whole race. In both sexes, W rowers showed higher (p > 0.05) T2 values (100.8 ± 0.9%) with respect to T1 (99.2 ± 0.9%) ones. Female athletes showed a higher (p ≤ 0.05) T1 with respect to T2 in NW, Q, and NQ, whereas male athletes exhibited a higher T1 (p ≤ 0.05) than T2 speed only in NQ. While to be admitted to the final phase of the competition, the rowers tended to favor a positive race strategy (88%); during the final phase, a difference (p = 0.43) emerged for outcome, with the majority of medalists (67%) adopting a negative race strategy. These results suggest that winners have applied a different race strategy compared with the other groups in consequence to a higher efficiency of anaerobic metabolism.

RESUMO

Relationships between heart rate recovery after exercise (HRR, baseline heart rate variability measures (HRV), and time to perform a 10Km running trial (t10Km) were evaluated in "master" athletes of endurance to assess whether the measured indexes may be useful for monitoring the training status of the athletes. Ten "master" athletes of endurance, aged 40-60 years, were recruited. After baseline measures of HRV, the athletes performed a graded maximal test on treadmill and HRR was measured at 1 and 2 minutes from recovery. Subsequently they performed a 10Km running trial and t10Km was related to HRV and HRR indexes. The time to perform a 10Km running trial was significantly correlated with baseline HRV indexes. No correlation was found between t10Km and HRR. Baseline HRV measures, but not HRR, were significantly correlated with the time of performance on 10km running in "master" athletes. The enhanced parasympathetic function at rest appears to be a condition to a better performance on 10km running. HRV can be simple and useful measurements for monitoring the training stratus of athletes and their physical condition in proximity of a competition.

RESUMO

BACKGROUND: The aim of this study was to assess the influence of the autonomic system on the performance of repeated sprints, involving predominantly neuromuscular power, in young soccer players. METHODS: Twelve young soccer players, selected for the Sicilian Regional Football Representative, mean age 15 years, were recruited. Baseline heart rate variability (HRV) was measured and indices of power spectral analysis (LF, HF, and LF/HF ratio) were calculated to evaluate the sympathovagal balance. The athletes performed 10 maximal 6-second cycling sprints (RS), interspersed with 30 seconds of recovery, to measure the peak power output (PP) represented by the highest power value recorded during a 6-second sprint, and the mean peak power output (MPP) represented by the average of all highest power values recorded within a repeated-sprint bout. RESULTS: PP was negatively correlated with LF (ρ=-0.685, P=0.0141) and LF/HF (ρ=-0.709, P=0.0098), and positively correlated with HF (ρ=0.684, P=0.0142). MPP was negatively correlated with LF (ρ=-0.610, P=0.0350) and LF/HF (ρ=-0.606, P=0.0366), and positively correlated with HF (ρ=0.731, P=0.0070). CONCLUSIONS: Our study shows that a baseline parasympathetic predominance in the autonomic nervous system balance is associated with a better neuromuscular contribution to performance, resulting in higher values of PP and MPP during brief repeated maximal cycling sprints. The assessment of baseline HRV before exercise may be useful for to monitor the physical condition of young soccer players and their readiness status to a higher performance.
