Evidence suggests that higher testosterone levels may provide an athletic advantage. Therefore, it is of practical interest to examine the association between testosterone levels and power- and streng...
Few data are available on sleep characteristics of elite track-and-field athletes. Our study aimed to assess (1) differences in sleep between sexes and among different track-and-field disciplines, (2)...
Sleep characteristics of 16 elite Olympic-level track-and-field athletes (male: n = 8; female: n = 8) were assessed during the preseason period, at baseline (T0), and during the in-season period, afte...
Female athletes displayed better sleep efficiency (88.69 [87.69-89.68] vs 91.72 [90.99-92.45]; P = .003, effect size [ES]: 0.44), lower sleep latency (18.99 [15.97-22.00] vs 6.99 [5.65-8.32]; P < .001...
Sleep quality and quantity were suboptimal at baseline in Olympic-level track-and-field athletes. Large differences were observed in sleep characteristics between sexes and among different track-and-f...
Most epidemiological studies on track-and-field meets have been limited to the Olympics and world championships. These are meets in which only high-performance athletes participate at a certain time o...
The number and incidence of injuries requiring on-field medical care during or after the event were obtained from 39 track-and-field meets. Injuries were defined as cases that required on-field medica...
A total of 191 injuries were reported. This study identified a population with a high incidence of injury (middle- and long-distance events, combined events, and athletes over the age of 19), areas wi...
The results provide insights into the trends, locations, and transport of injured athletes during track-and-field meets. Professionals will better understand the injuries occurring during track-and-fi...
Agriculture machinery navigating along permanent traffic lanes in the farmland may avoid causing extensive soil compaction. However, the permanent traffic lanes are frequently covered up or eliminated...
To understand athletic performance before and after puberty, this study determined: 1) the age at which the sex difference increases among elite youth track and field athletes for running and jumping ...
Track and field records of elite USA male and female youth (7-18 years) across three years (2019, 2021, and 2022) were collected from an online database (athletic.net). The top 50 performances were re...
Males ran faster than females at every age in the 100, 200, 400 and 800 m (P < 0.001). When combining all running events, the sex difference (%) was 4.0 ± 1.7% between 7-12 years and increased to 6.3 ...
Prior to 12 years of age in elite youth track and field athletes, there was a consistent and significant sex difference of ~5%, such that males ran faster and jumped higher and farther than females. T...
Generalizability theory (GT) has been used throughout the scientific literature to ensure validity, reliability, and generalizability in different sport contexts. However, there is a small number of s...
The literature on motor development and training assumes a hierarchy for learning skills-learning the "fundamentals"-that has yet to be empirically demonstrated. The present study addressed this issue...
Track and field (T&F) is a highly popular sport for adolescents. The diversity of running, jumping, and throwing events within the sport can result in unique injury patterns for adolescent track and f...
Emergency department (ED) data from the National Electronic Injury Surveillance System were obtained for a 20-year period from 2000 through 2019. Cases involving 14- to 18-year-olds participating in T...
8,060 track and field related ED encounters were observed, representing an estimated 272,227 encounters nationally over the 20-year study period. The rate of ED encounters increased significantly over...
There was an increasing trend of ED visits from adolescent T&F participants throughout the 20-year study period with different injury patterns observed by sex and T&F event discipline....
Sports records hold valuable insights into human physiological limits. However, presently, there is a lack of integration and evolutionary patterns in the recorded information across various sports....
We selected sports records from 1992 to 2018, covering 24 events in men's track, field, and swimming. The Gembris prediction model calculated performance randomness, and Pearson correlation analysis a...
1) The evolution range indicates that swimming events generally have a larger annual world record variation than track and field events; 2) Gembris's predictions show that sprint, marathon, and swimmi...
Sports record evolution is closely linked not only to specific sports technology but also to energy expenditure. Strengthening basic physical training is recommended to enhance sports performance....
We aimed to verify the reliability of muscle thickness and luminance evaluation of the deep leg muscles using an ultrasound device....

Track and field, Participants: high school track and field long distance athletes (N = 10, female: 50.0%, age = 16.0 ± 2.8 years, BMI = 18.2 ± 2.3 kg/m2) PARTICIPANTS: This study included Japanese hig...
The thickness and echo intensity of tibialis posterior, flexor digitorum longus, and soleus muscles in the posterior medial tibia were clarified....
The echo intensity evaluation of the tibialis posterior muscle showed an additive error....
The study suggested that the results could be clinically applied clinically, except for the evaluation of echo intensity of the posterior tibialis muscle....
