Pacing in long-distance running

Effects of Pacing Properties on Performance in Long-Distance Running This article focuses on the performance of runners in official races. Based on extensive public data of participants in races organized by the ‘Boston Athletic Association’, how different pacing profiles can influence performance in a race. The pacing of an athlete refers to the running speed in different sections of the race. The data acquisition includes three years of data published by the racing agencies, and mainly includes times at various points that provide information about the individual runner’s speed profile. 10 km, half marathon and the marathon were taken into account with a record of 120,472 runners. Since age is a crucial but complex determinant for performance, the age effect was first modeled gender and distance-specific. High degree polynomials and used to cross validation to select models that are both accurately and sufficiently generalizable. Thereafter, a clustering of the racing profiles was performed to identify the dominant pacing profiles that select the runners. After the influences of age were compensated, a descriptive pattern mining approach has been applied to select reliable and informative aspects of the pacing that best determine optimal performance.

Vitamin D in Swiss athletes

Predictive Factors for Vitamin D Concentrations in Swiss Athletes: A Cross-sectional Study Vitamin D concentrations that correspond to 75 Nmol / L 25 (OH) D were associated with the maintenance of muscle function, growth and regeneration, optimal bone health and immunology for athletes. In this study, the prevalence and predictors for insufficient 25 (OH) D concentrations were examined for athletes. 603schweizer athletes were evaluated.25 (OH) D was analyzed by high performance liquid chromatography (HPLC).A standardized questionnaire was used to collect information about possible predictors for the 25 (OH) D concentrations. 50 \ .5% showed inadequate 25 (OH) D concentrations.Differences in the predicted probability of inadequate 25 (OH) D were in vitamin D supplementation (42%) compared to non-supplementation (52%), for indoor athletes (58%) against outdoor sports (43%) and inThe sun-senior autumn season (49%), winter (70%) and spring (57%) compared to summer (17%). Higher BMI Z values and age were connected to higher 25 (OH) D concentrations. Inadequate 25 (OH) D concentrations are common for athletes, especially in a recent age, in those who have not been supplemented, for athletes trained in closed rooms, and during the sun-senior season.

The left-hearted function in swimmers and runners

Left Ventricular Structure and Function in Elite Swimmers and Runners Sport-specific differences in the left ventricle (LV) of athletes who are not moving in the water have been studied several times. However, compare with athletes in water sports are sparse.The aim of this study was to investigate differences in the LV structure and function of elite schemes and runners. At the study, 16 elite swimmer 16 elite runners participated.All athletes ran through echocardiography at rest. The LV dimension, the global systolic and diastolic LV function were determined and the LV mechanism determines. The early diastolic function was lower in floats lower, including the maximum early transmitral filling speed, the middle early mitral ring tip speed and the ratio of peak early velocity to the late transmitral filling speed. The diastolic mechanics index of the time until the maximum speed rate also occurred in diastoles in floats. The heart time volume was greater with swimmers, which was attributed to their higher heart frequencies.All other indices of systolic LV function and dimensions were similar between the groups.

The influence of gender, age and performance level on the pacing in the Ironman

The effect of sex, age and performance level on pacing of Ironman triathletes The aim of this study was to investigate the effects of gender, age and performance level on the pacing of Ironman triathlets. The section times in swimming, cycling and running as well as the total time of 343'345 athletes who participated between 2002 and 2015 at 253 different Ironman triathlons were analyzed. The participants were divided into nine performance groups after their total time. The times when swimming, cycling, running and changing zones were specified as a percentage of the total time.Women turned relatively little time (%) when swimming, running and changing as well as more time (%) when cycling than men. The fastest power group was relatively faster during running (34.8 ± 1.4 compared to 40.3 ± 3.0%) and the change zone (0.9 ± 0.3 compared to 2.2 ± 0.6%) and relatively slowerWhen swimming (10.2 ± 0.8) against 9.8 ± 1.5%) than the slowest power group. The athletes of the younger age groups were relatively faster when swimming, and in the change zone, but relatively slower when cycling.

The influence of gender and performance level on the pacing in the Duathlon

The Effect of Sex and Performance Level on Pacing in Duathlon The goal of the study was the study of the effects of sex and performance on pacing on the short (Run 1 with 10 km, bike with 50 km and Run with 2 5 km) and the long route (Run 1 with 10 km, bike with 150Km and Run 2 with 30 km) at the Powerman World Cup ‘Powerman Zofingen’. All finishers (n = 6671; women, n = 1037; Men, n = 5634), which were either in the short or long-distance version of ‘Powerman Zofingen’ from 2003 to 2017, were used for the time completed in each discipline (RUN 1, Bike and Run 2) and Change Zone (Tran) from Run 1 to Bike (Tran 1) and Bike to Run 2 (Tran 2). The athletes were divided into quartile (Q) groups (Q 1, Q 2, Q 3 and Q 4), where Q 1 was the fastest and Q 4 slowest. On the short corner of both sexes, a middle discipline / change zone × Quartile interaction over the relative time was observed, with Q 1 in Tran 1, Tran 2 and Run 2 relatively the fastest and the slowest in bike. On the long distance, both sexes were observed with a strong interaction between discipline and change zone × Quartile over the relative time where Q 1 was relatively fastest in Tran 1, Tran 2 and Run 2 and the slowest in bike.

Pulmonary edema by swimming

Swimming induced pulmonary oedema in athletes - a systematic review and best evidence synthesis A lung edema (SIPE) caused by swimming is an unusual event that is usually showing itself when swimming in cold water. Prevalence is most likely undergraduate and the underlying mechanisms are controversial. The aim of this work was to summarize the evidence regarding prevalence, pathophysiology and treatment of the pulmonary pulmonary edema in endurance athletes. Searched Medline, Embase, Scopus and Google Scholar.The Level I-IV was included from 1970 to 2017.For clinical trials, only publications were considered, which report on swimming-induced pulmonary edema. The distortion potential was evaluated with the Robin I tool and the quality of the evidence with the Cochrane Grade system.For data synthesis and analysis, a best evidence synthesis was used. A total of 29 studies were recorded with 174 athletes.The most common symptoms was coughing, shortness of breath, foam and hemoptyseis. The risk of distortion for clinical trials included 13 with moderate risk, 3 with severe and 4 critical risk. Four of the pathophysiological studies had a moderate risk, 3 a serious risk and 1 a critical bias risk. Best evidence analysis showed a strong correlation between immersion in cold water and the increase in the CVP (central venous pressure), the MPAP (mean pulmonary arterial pressure), the PVR (peripheral vascular resistance) and the PAWP (pulmonary arterial wedge pressure), resulting in oneInterstitial asymptomatic edema led. The results of this study suggest a moderate relationship between the water temperature and the spread of SIPE. The presence of clinical symptoms coughing, dyspnoe, foam and hemoptyseis is strongly indicating a sipe during or immediately after swimming. There are limited indications that risk factors are pre-existing, which lead to SIPE when exposed during swimming strenuous physical activity.

E-Book for running shoes

Relaxed and enduring running training is only possible with the right running shoes. Due to the anatomical conditions (supination or overpronation), everyone needs a slightly different shoe. Different models without support, with supporting indoor element or strong until not dampening come here in the game. In the end, the shoe should fit to the runner and feel good. In general, running shoes can be divided into four categories: neutral shoes, stable and motion control shoes, Leightweight coaches and trekking shoes.

What happens during a 48-h running?

Pacing and Changes in Body Composition in 48 h Ultra-Endurance Running—A Case Study The pacing was examined for elite and master runners, which participate in marathon and ultra-marathon races up to 100 km and 100 miles, but not for longer ultra-marathons. In this case study, a 54-year-old ultramarathon runner was investigated, which wanted to achieve as many kilometers as possible in 48 hours. The changes in running speed during the race and selected anthropometric properties (body mass and body water) using the analysis of bioelectric impedance during and after the race were analyzed. The runner achieved a total distance of 230 km and the running speed did not take on linear during the race. Body weight decreased while the percentage of body water rose over the race non-linear.

Pacing during marathon

Pacing Strategies in the ‘Athens Classic Marathon’: Physiological and Psychological Aspects Despite the increasing scientific interest in the relationship between pacing and the performance of the marathon, there are a few information about the combination of pacing with physiological and psychological parameters. The aim of the present study was therefore to investigate the role of physical fitness and training properties at pacing at the “Athens Classic Marathon”. The finishers of this race in 2017 (women, n = 26, age 40.8 ± 9.4 years; men, n = 130, old 44.1 ± 8.6 years) were analyzed on their paping during the race, theMotivation of Marathon Scale (MOMS) examined and a number of physiological tests performed. Women and faster leisure runners took a more uniform pacing. A more uniform pacing was associated with a higher aerobic capacity and less muscle force in men, but not in women. Men with even pacing achieved higher psychological coping, self-esteem, life consent, recognition and competition as their colleagues with less uniform pacing.
