SPEED ENDURANCE ENHANCEMENT IN TRACK-AND-FIELD ATHLETES FROM THE KOLA PENINSULA THROUGH BLOOD LACTATE CONTROL

Aim. The article deals with establishing the effect of the method for speed endurance enhancement in female track-and-field athletes from the Kola peninsula through blood lactate control at 11 mmol/l. Materials and methods. The study was conducted from November 2017 to April 2018. At the first stage, we created an experimental group of track-and-field athletes from sports school No 4 (Murmansk). All female athletes (middle-distance runners, n = 34) were 18–20 years old and possessed the first or the second adult category at the time of selection. 1 km test was conducted to establish speed endurance in participants. At the second stage, a 6-month experiment was conducted: all athletes had a 6-week interval training at a distance of 1 km with timekeeping, pulsometry, and blood count for establishing blood lactate immediately after each segment of the distance. At the third stage, a control 1 km test was conducted. The authors analyzed the results obtained using statistical methods (р ≤ 0.01). Results. It was established that the main methods for the development of speed endurance in female athletes are repetitive and interval methods. The main means of speed endurance enhancement are resistance running, running rhythm, and pursuit running. In the first two months of interval training, a significant increase in speed endurance, pulse values, and lactate (no more than 11 mmol/l) was registered. Stagnation of results was registered during the 4th, 5th, 7th, 11th, and 12th weeks of training. Conclusion. The data obtained can be used as a part of special physical preparation in female track-and-field athletes aged 18–20 years from Murmansk and Murmansk region.
