TY - JOUR T1 - Influence of Speed-strength Training on the Concentration Indicators of Schoolchildren Aged 13-14 Years with Different Typology A1 - Georgiy Georgievich Polevoy JF - Pharmacophore JO - Pharmacophore SN - 2229-5402 Y1 - 2021 VL - 12 IS - 6 DO - 10.51847/oCGvk8tmjd SP - 15 EP - 18 N2 - The present article aimed to investigate the effect of speed-strength classes on the concentration indicators of thirteen- to fourteen-year-old students with diverse typologies. The study period was three months. All physical education classes were held for 40 minutes and twice a week. Students from the control class (20 children) studied based on the common program, and students from the special group (20 children) further carried out a set of speed and strength exercises. All students performed the tapping test (strength of the nervous system) and the Bourdon test (concentration of attention). After a special study, the concentration values in the control class in kids with a strong nervous system improved by 5% (p>0.05) and with a weak one - by 6% (p> 0.05). In the experimental class, concentration indicators increased by 13% (p UR - https://pharmacophorejournal.com/article/influence-of-speed-strength-training-on-the-concentration-indicators-of-schoolchildren-aged-13-14-ye-mvaoafuzpmd0ux9 ER -
