El rol de la inteligencia emocional en el rendimiento en escalada

Purpose: To investigate the association between emotional intelligence (EI) and self-reported climbing ability. Methods: Redpoint climbing ability was used as an indicator of rock climbing performance and EI were assessed as ability and a trait using two different questionnaires MSCEIT and SSEIT in forty-three climbers (15 females and 28 males). ANOVA was used to analyse differences between male and female and advanced and elite climbers in EI parameters in both questionnaires. The analyses were also adjusted by age using ANCOVA. Results: Linear regression analysis revealed that there are no differences between trait EI and climbing performance, but we found the component `Facilitation Thought’ of EI measured as ability was inversely associated with the highest red-point ability. Conclusion: Our results suggest that elite climbers do not use their emotions to facilitate thinking as much as expert climbers, which is positively related to performance. Future researches should direct to investigate how elite climbers manage their emotions.Objetivo: Investigar la asociación entre la inteligencia emocional (IE) y el nivel de escalada autoinformada. Método: Se usó el nivel de escalada ensayado como un indicador del rendimiento de la escalada en roca y se evaluó en cuarenta y tres escaladores (15 mujeres y 28 hombres) la IE como habilidad tanto como rasgo, utilizando dos cuestionarios diferentes MSCEIT y SSEIT. Se utilizó un ANOVA para analizar las diferencias entre los escaladores masculinos y femeninos y avanzados y élite en los parámetros de IE en ambos cuestionarios. Los análisis también se ajustaron por edad utilizando un ANCOVA. Resultados: El análisis de regresión lineal reveló que no hay diferencias entre el rasgo IE y el rendimiento en escalada, pero encontramos que el componente´facilitación del pensamiento´ de IE como habilidad estaba inversamente asociado con un mayor nivel de escalada ensayada. Conclusión: Nuestros resultados sugieren que los escaladores de élite no usan sus emociones para facilitar el pensamiento, en relación con los escaladores expertos, lo que se relaciona positivamente con el rendimiento. Las investigaciones futuras deben dirigirse a investigar cómo los escaladores de élite manejan sus emocione

Body adiposity index and incident hypertension: The Aerobics Center Longitudinal Study

Background and aim The body adiposity index (BAI) has been recently proposed as a new method to estimate the percentage of body fat. The association between BAI and hypertension risk has not been investigated yet. The aim of our study was to evaluate the ability of BAI to predict hypertension in males and females compared with traditional body adiposity measures. Methods and results The present follow-up analysis comprised 10,309 individuals (2259 females) free of hypertension from the Aerobics Center Longitudinal Study, who completed a baseline examination between 1988 and 2003. Body adiposity measures included BAI, body mass index (BMI), waist circumference, hip circumference, percentage of body fat and waist to hip ratio (WHR). Incident hypertension was ascertained from responses to mail-back surveys between 1990 and 2004. During an average of 9.1 years of follow-up, 872 subjects (107 females) became hypertensive. Hazard ratios (HRs) and 95% confidence intervals (95% CI) showed that males in the highest categories of all body adiposity measures showed a higher incident risk of hypertension (HRs ranged from 1.37 to 2.09). Females showed a higher incident risk of hypertension only in the highest categories of BAI, BMI and WHR (HRs ranged from 1.84 to 3.36). Conclusion Our results suggest that in order to predict incident hypertension BAI could be considered as an alternative to traditional body adiposity measures.The authors thank the Cooper Clinic physicians and technicians for collecting the data, and staff at the Cooper Institute for data entry and data management.

Hemodynamic and cardiorespiratory predictors of sport rock climbing performance

Rock-climbing performance is largely dependent on the endurance of the forearm flexors. Recently, it was reported that forearm flexor endurance in elite climbers is independent of the ability to regulate conduit artery (brachial) blood flow, suggesting that endurance is not primarily dependent on the ability of the brachial artery to deliver oxygen, but rather the ability of the muscle to perfuse and use oxygen, i.e. skeletal muscle oxidative capacity. Purpose: The aim of the study was to determine whether an index of oxidative capacity in the flexor digitorum profundus (FDP) predicts the best sport climbing red-point grade within the last 6 months. Participants consisted of 46 sport climbers with a range of abilities. Methods: Using near infrared spectroscopy, the oxidative capacity index of the FDP was assessed by calculating the half-time for tissue oxygen re-saturation (O2HTR) following 3-5 min of ischemia. Results: Linear regression, adjusted for age, sex, BMI and training experience, revealed a 1s decrease in O2HTR was associated with an increase in red-point grade by 0.65 (95% CI: 0.35-0.94, AdjR2 = 0.53). Conclusions: Considering a grade of 0.4 separated the top 4 competitors in the 2015 International Federation Sport Climbing World Cup, these findings suggest that forearm flexor oxidative capacity index is an important determinant of rock climbing performance.N/

Differences in oxygenation kinetics between the dominant and non-dominant flexor digitorum profundus in rock climbers

Purpose. This study examined differences in oxygenation kinetics in the non-dominant and dominant flexor digitorum profundus (FDP) of rock climbers. Methods. Participants consisted of 28 sport climbers with a range of on-sight abilities (6a+ to 8a French Sport). Using near infrared spectroscopy, oxygenation kinetics of the FDP was assessed by calculating the time to half recovery (t½ recovery) of the tissue saturation index (TSI) following 3-5 min of ischemia. Results. A 2-way mixed model ANOVA found a non-significant interaction (p =0.112) for TSI x sex. However, there was a significant the main effect (p =0.027) handedness (dominant vs. non-dominant FDP). The dominant forearm recovered 13.6% quicker (t½ recovery mean difference = 1.12 sec, 95% CI 0.13 to 2.10 sec) compared to the non-dominant FDP. This was not affected by 6-month on-sight climbing ability or sex (p =0.839, p =0.683). Conclusions. Significant intra-individual differences in oxygenation kinetics of the FDP were found. Improvements in oxygenation kinetics within the FDP are likely due to the abilities of the muscle to deliver, perfuse and consume oxygen. These enhancements may be due to structural adaptations in the microvasculature such as an increase in capillary density and an enhanced improvement in capillary filtration

Ethnic differences in body composition and somatotype in Mapuche and non-Mapuche school children from Temuco-Chile

Los cambios culturales y demográficos en la etnia Mapuche chilena, han generado modificaciones en estilos de vida y la estructura morfofuncional de su población, incentivando de esta forma el estudio del estado de salud en jóvenes chilenos. El objetivo de este estudio fue analizar las diferencias en composición corporal y somatotipo entre niños Mapuche y no-Mapuche de la Comuna de Temuco en Chile. Participaron 122 niños Mapuche y 146 niños no-Mapuche entre 10 y 13 años. Se recogieron medidas de peso, talla; pliegues cutáneos y diámetros óseos; siguiendo el protocolo de la Sociedad Internacional para el desarrollo de la cineantropometría (ISAK). Se determinó el índice de masa corporal (IMC), estado nutricional, grasa corporal total y somatotipo (endomorfía, mesomorfía y ectomorfía). Los resultados indican que los niños Mapuche de 10 años presentaron valores menores de IMC (p0,01), grasa corporal total (p 0,001), así como de endomorfia y mesomorfia (p0,01) respecto a los no-Mapuche. Los niños Mapuche de 11-12 años presentaron valores menores de grasa corporal total (p0,01) y de endomorfia y ectomorfia (p0,05), comparados con los no-Mapuche. Los niños Mapuches de 13 años presentaron valores menores de grasa corporal total (p0,001) y de endomorfia y ectomorfía (p0,01) que el no-Mapuche. Los escolares Mapuches tienen menor grasa corporal que los niños no-Mapuche, el somatotipo predominante en la etnia Mapuche es el mesomórfico, observándose un componente endomórfico menor cuanto mayor es la edad. Son necesarias políticas de salud pública en los jóvenes, fundamentalmente educativa, para garantizar niveles adecuados de calidad de vida en ambas poblaciones Mapuches y no-Mapuche.The cultural and demographic development of modern society has also affected the Mapuche ethnia and has influenced changes in lifestyles and in the morphofunctional structure of the population, particularly in young people. The purpose of this study was to determine differences in body composition and somatotype between Mapuche and non-Mapuche children from Temuco, Chile. A total of 122 Mapuche and 146 non-Mapuche children between 10 and 13 years old participated in the study. The measurements included were weight, height, skinfold thickness of triceps, subscapularis, supraspinatus and calf; perimeters of contracted and relaxed arm, waist and calf circumference; and humeral and femoral diameters, all following the procedures reference manual (ISAK). Several indexes were calculated: Body Mass Index (BMI), weight status (underweight, normoweight, overweight, obesity), total body fat (fat mass, percentage of fat mass and percentage of fat mass >20% of obesity) and finally, somatotype (endomorph, ectomorph, mesomorph). Ten year-old Mapuche children had lower values for BMI (p 0,01), total body fat (p0.001), and endomorphic and mesomorphic values (p0.01), compared to non Mapuche children. Mapuche children of 11-12 years of age had lower values for total body fat (p0.01), and endomorphic and ectomorphic values (p0.05), compared to non-Mapuche children. Thirteen year-old Mapuche children had lower values for total body fat (p0.001), and endomorphic and ectomorphic values (p0.01), compared to non-Mapuche children. Mapuche children had lower fat mass than non-Mapuche children, and the main somatotype among Mapuche children is mesomorphic with a reduction of the endomorphic component with increasing age. Public policy for youth is required, mainly educational, to guarantee appropriate levels of quality of life for both Mapuche and non-Mapuche populations

Cognitive Function of Climbers: An Exploratory Study of Working Memory and Climbing Performance

Sport climbing requires a combination of physical and cognitive skills, with working memory (WM) playing a crucial role in performance. This study aimed to investigate the association between WM capacity and climbing ability, while considering potential confounding factors including sex, age, education level, and climbing experience. Additionally, the study compared prefrontal cortex (PFC) hemodynamic responses among different climbing ability groups and sex during WM performance. Twenty-eight climbers participated, with WM assessed using the eCorsi task and PFC hemodynamic responses measured with near infrared spectroscopy (NIRS). Initial linear regression analyses revealed no association between WM and climbing ability. However, significant associations were found after adjustment for covariates. Specifically, sex (p = .014), sex in conjunction with age (p = .026), sex combined with climbing experience (p = .022), and sex along with education level (p = .038) were identified as significant predictors of differences inWM between Expert and Elite climbers. Additionally, notable differences in PFC hemodynamic responses were observed between Expert and Elite climbers, as well as between sexes during the WM task, providing support for differences in WM capacity. This study contributes to understanding the complex relationship between WM capacity and climbing performance, emphasizing the need to account for influencing factors in assessments

Physiology of sport climbing

El presente trabajo revisa la literatura científica existente sobre la escalada deportiva con el objetivo de analizar en profundidad las características antropométricas y fisiológicas del escalador deportivo, así como las exigencias fisiológicas en el desarrollo de la actividad. La literatura revisada sugiere que los escaladores se caracterizan por tener un bajo peso corporal y un bajo porcentaje de masa grasa. También una alta fuerza de prensión manual y una alta fuerza resistencia. Algunos autores han considerado el consumo máximo de oxígeno como un determinante del rendimiento en escalada, sin embargo los resultados son contradictorios. Otros parámetros fisiológicos son analizados durante y después de la escalada. Se han detectado importantes diferencias metodológicas entre los estudios analizados, sugiriendo la necesidad de estandarizar los protocolos de evaluación en este deporte. La presente revisión contribuye de manera significativa a un mayor conocimiento de las características de este deporte y de quienes las practican, identificando diversas áreas de interés que requieren futuro estudio.The purpose of the present paper is to review the existing research on anthropometric and physiological characteristics of sport climbers as well as the physiological responses during the sport climbing. The literature suggests that the sport climbers are characterised by both a low percentage body fat and body mass. A high handgrip strength and high endurance strength also are specific characteristics of sport climbers. In contrast, it is not clear whether maximal oxygen consumption is a determinant of sport climbing performance. Several physiological parameters have been analysed during and after sport climbing such as heart rate, blood lactate and maximal strength. We have observed many differences in the assessment methodology between the studies, suggesting that a standardization of the evaluation protocols is needed in this sport discipline. This review provides a wide knowledge of the characteristics of this sport, as well as identifies particular areas that require further attention

Ultraviolet sun exposure and sun protection behaviors in outdoor rock climbers

Background: Overexposure to sunlight and sunburn are the main preventable causes of skin cancer. Outdoor sports are associated with significant levels of sunlight exposure. Aims: We sought to quantify the sun radiation exposure received by outdoor rock climbers and assess their sun exposure habits, sun protection behaviors, attitudes, and knowledge regarding skin cancer. Methods: From April to June 2021, outdoor rock climbers contacted via email completed an online validated self-reported questionnaire on sun related habits, behaviors, attitudes and knowledge. As a pilot trial, ten participants wore a personal dosimeter during two outdoor climbing weekends in May and November 2021. Ambient ultraviolet radiation (UVR) was also recorded. Results: A total of 217 outdoor rock climbers (103 women), mean age 36.8 ± 8.8 years (range 20–70 years) and median climbing practice per week of 8 h (IQR 7.5) were studied. Two in three (65.9%) participants reported at least one sunburn event during the previous rock climbing season. Of the survey respondents, 49.3% reported using sunscreen with SPF ≥ 15, 47% wore sunglasses, and 14.3% indicated they reapplied sunscreen every two hours. The median personal UVR dose measured during the two outdoor climbing weekends analyzed was 5.2 (IQR 1.8) and 8.8 (IQR 1.1) standard erythemal doses, respectively. Conclusions: The high rates of sunburn, the elevated personal UVR measured and the clearly insufficient sun protection practices followed during rock climbing together with unsatisfactory attitudes towards tanning reveal the need to develop explicit sun protection campaigns and educational strategies to reduce the risk of skin cancer among the athletes studied.10 página
