Discussion on the Core Strength Training Method for 100-Meter Event in Track and Field Sports

In track and field sports,the 100-meter race is an extremely intense sport that requires effective training of athletes’core strength.From the perspective of adolescents,in order to enhance core strength,it is necessary to effectively fix the pelvic position in the process of exercise,so that the core stability,balance,and coordination of athletes can be improved.The training process of the 100-meter event is mainly an anaerobic metabolic exercise,it is necessary to ensure that athletes maintain a high level of physical readiness during the exercises and concentrate highly on their core strength,so that they can achieve excellent results.This paper analyzes the core strength training for the 100-meter event in track and field sports,discusses its importance,and puts forward specific training methods,hoping to provide guidelines for relevant researchers.

Common Sports Injuries and Preventive Measures for Athletes—Take The Track and Field Team Athletes in Yushan County as an Example

Taking the common sports injuries and preventive measures of Yushan County middle school track and field athletes as the research object,the sports injuries of Yushan County middle school track and field athletes were investigated and analyzed from the angle,type,location and nature of sports injury.Research on sports injury problems,trying to find the causes of sports injuries in daily training of track and field athletes,and proposed targeted preventive measures based on the specific situation of Yushan County Middle School.The results show that 77.70%of track and field athletes have suffered sports injury and periostitis and ligament/muscle strains are the most common forms of injury,and lower limbs are more prone to sports injuries than upper limbs.

The frequency and performance trends of European countries in the U18 and U20 rankings for 1500 m and 3000 m between 2009-2020

We purpose to determine the nationality of the European middle-distance athletes under 18 years(U18)and under 20 years(U20)during the last decade,to verify the participation trend for each country,and to assess whether the place of competition can be associated with the athletes ranking position.The sample comprised 902 European male runners,ranked among the best finishers from 2009 to 2020.The athletes were divided into two categories(n_(U18)=266;and n_(U20)=636)of two distances(n_(1500m)=397;n_(3000m)=505).The Mantel test was used for participation trend and the Chi-square test(χ^(2))was used to verify differences between the ranking position and the place of competition.For both distances,the highest number of athletes were from Spain(n=127),followed by Turkey(n=62)and Great Britain(n=50).No significant trends were shown for most of the countries,in both distances.A positive trend was shown for Slovenia(i.e.,3000m)over the years.A non-significant association was verified between the countries and the ranking position,as non-significant differences were proved for the place of competition.This information may be useful to guide athlete development programs in each country.

Relationships Between Vertical Jump Metrics and Sprint Performance,and Qualities that Distinguish Between Faster and Slower Sprinters

Purpose This study aimed to investigate the relationships between vertical jump metrics and phases during a 60 m sprint.The variances in strength qualities between sprinters of different ability levels were also compared.Methods Eighteen young male elite sprinters(age:18.1±1.3 years;stature:1.72±0.07 m;body mass:66.3±6.2 kg)were assessed for squat(SJ),countermovement(CMJ),drop(DJ),and standing long jumps,a maximal load back-squat,and a 60-m sprint from a block-start.The relationships between sprint performances with all variables were analysed using correlation and multiple regression while discriminative parameters between fast(100 m time:~10.50 s)and slow(~11.00 s)sprint groups were assessed using independent t-tests.Results Higher associations existed between vertical jumps and longer sprint distances,especially between SJ height and relative peak power with 10 m(r=−0.47 and−0.47,respectively),30 m(−0.71 and−0.74),60 m(−0.76 and−0.81),10-30 m(−0.80 and−0.86),and 30-60 m(−0.78 and−0.84)sprint distances.Concurrently,variables such as relative maximal-strength,relative SJ parameters(height,peak force,and peak power),relative CMJ peak power,and reactive strength index(DJ from 35 cm height)had significant discriminative ability and correlations(P<0.05)with sprint distances involving maximal velocity and flying-start.Additionally,a combination of SJ height and relative maximal-strength during back-squat accounted for 75%of the variance in 60 m sprint times.Conclusions Relative measures of multiple strength metrics may provide better insight regarding factors that enhance sprint performance.Adequate maximal-strength,high explosive power,and reactive strength seem necessary to improve sprint performance in young male elite sprinters.
