Pacing in half marathon and marathon

Performance and Pacing of Age Groups in Half-Marathon and Marathon The aim of the present study was to investigate the age-related differences in performance and pacing in a half marathon compared to a marathon. All Finishers (N = 9137) of the Half Marathon (N = 7258) and the Marathon (N = 1853) Ljubljana 2017 with available data for intermediate times during the race were analyzed on the pacing. Half marathon runners were slower at women than marathon runners (2.77 ± 0.35 compared to 2.86 ± 0.39 m / s), but faster in men (3.14 ± 0.45 compared to 3.08 ± 0.46 m /s). In both races, the age group was <25 years the fastest and age group> 54 years slowest. All age groups showed a positive pacing (decrease in speed in the race) in both the renown distances and the sexes, each segment being slower than the previous one. In the marathon, however, a final spurt was observed, but not in the half marathon. For most age groups, the pacing in the half marathon was more even than in the marathon.

Heart function for athletes

Left Ventricular Systolic Function Assessed by Speckle Tracking Echocardiography in Athletes with and without Left Ventricle Hypertrophy The aim of this study was selected parameters for the elongation and rotation of the left ventricle (the basal rotation index (BR), the basal scope limit index (BCS) and the global longitudinal strain (GLS) of the left ventricle) in male athletes with physiological cardiac hypertrophy (LVH group)as well as athletes (non-LVH group) and non-athletes without hypertrophy (control group, CG) to evaluate. They were evaluated before and after a stress test by means of transthoracic echocardiography and Speckle tracking echocardiography.The LVH group showed a lower BR in peace than the non-LVH group and the CG. The physical effort had no influence on the BR, and this effect did not differ between the groups. There was a combined influence of LVH and physical effort on BR and BCS, but no significant differences in BCS and GLS at rest between the groups. A higher BCS and a lower GLS after loading in the LVH group were detected compared to the CG. The left ventricular basal rotation as well as the longitudinal and peripheral loads showed a lower difference between rest and strain in subjects with significant myocarde hypertrophy.

What influences the performance in the ultramarathon?

Different predictor variables for women and men in ultra-marathon running – the Wellington Urban Ultramarathon 2018 Ultra marathon races are becoming increasingly popular. Women are now 20% of all finishers, and this number is growing.Predictors for the performance of women in the ultra-marathon run were rarely examined. The aim of this study was to investigate the performance-influencing variables for women and men at 62 km long Wellington Urban Ultramarathon 2018 (Wuu2K) and to create an equation to predict the ultra-marathon race. In women, the running volume were associated with racing time during exercise per week (km) and the personal best (PBT) in 5 km, 10 km and half marathon (min). For men, age, body mass index (BMI), runtime, running speed during training (min / km), Marathon-PBT and 5 km PBT (min) were associated with the race. For men, the ultra-marathon race can be predicted by the following equation: ultra-marathon race time (min) = -30,85 ± 0,2352 × Marathon PBT + 25,37 × 5 km PBT + 17,20 × training speed(Min / km).For women, the ultra-marathon race could be predicted by the following equation: ultra-marathon race time (min) = -148.83 + 3.824 × (half) - Marathon-PBT) + 9.76 × (10 km PBT)- 6,899 × (5 km PBT).

40 years Ironman Hawaii

Celebrating 40 Years of Ironman: How the Champions Perform We wanted to find out what discipline the strongest performance improvements in the history of the Ironman Triathlon in Hawaii and also which discipline had the greater impact on the entire race. Data from 1983 to 2018 The three best women and men of each year participated in the Ironman World Cup were taken into account.In addition to explorative data analyzes, linear regressions were carried out between intermediate times and years. Furthermore, a stepwise multi-linear regression was used, wherein the total time was used as a dependent variable and the intermediate times as an independent variable. Both women and men significantly improved their achievements from 1983 to 2018 at the Ironman World Cup. When swimming, there was the biggest difference in improvements between men and women (3.0% compared to 12.1%). Both women and men, a negative and significant decline in each discipline was found, with cycling the discipline with the greatest reduction. The results of gradual multiple regression showed that cycling for both sexes was the discipline with the highest influence on the total time.

Age of the highest performance in the ultramarathon

Age of maximum performance in Ultra-Marathon One of our published works was recently commented.In recent years, the number of participants has increased exponentially to 100 km ultramarathons. Although most participants have already participated in shorter runs for several years, we do not know much about the influence of age. Recently, the results of a study were published (Nikolaidis Pt and Knechtle B, 2018, J Strength Cond Res 27-Feb; DOI: 10.1519 / JSC.0000000000002539), whose goal was to analyze age, in which UltraLauer reach its highlightConsideration of age groups of 5-year intervals and analysis of the times of all participants and the 10 fastest times in each age group. The times of 370'051 athletes (44,601 women and 325,450 men) were analyzed, which completed at least a 100 km run between 1959 and 2016. The maximum age of performance was 40-44 years in women and all men at 45-49 the participants, while it was 30-34 years in women and 35-39 years in men when taken into account the top ten. In an analysis of year to year, the maximum age of the performance of women was 41 years and in men of 45 years, taking into account all participants and 39 years in women and 41 years in men taking into account the top ten. These results that do not differ from the previously reported have some non-physiological considerations to consider, such as the difference between marathon and ultramarathone, where the best athletes (younger age groups) can be selected for the marathon.

Competition preparation in an ultra-rider

Training and Body Composition during Preparation for a 48-Hour Ultra-Marathon Race: A Case Study of a Master Athlete Although the acute effects of ultra-endurance loads on the body composition were well examined, limited information about the chronic adjustments of the body composition to the ultra-endurance workout. The aim of the present study was to investigate the variations of training and body composition of an athlete during the preparation of a 48-hour ultra-marathon. For all training units (n = 73) before the race, running track, duration and tempo were recorded and body mass, body fat (BF), body water (%), visceral fat, fat-free mass (FFM) were four sizes (waist, upper arm, thighs and wade)and eight skin folds (chest, middle armpit, triceps, scapula, abdomen, beckenbamm, thigh and calf) measured in a 53-year ultra-endurance athlete. The main results of this study were that the athlete’s training plan followed a periodic pattern with respect to the training intensity and the training volume, which increased significantly with time, weight and body fat during the first 30 training units, and the sizes and skin folds were reflected in the respective decrease in theBody fat against. The results of this case study delivered useful information about the variation of the training and body composition during the preparation of an ultramarathon run in a male master ultramarathon runner.
