Sažetak
Some quantitative characteristics of muscular fatigue and processes of muscular regeneration after two different specific running workloads were analysed on a sample of eight well-trained middle- and long-distance runners, with the use of a measuring procedure encompassing six biomechanic parameters of muscular function, one functional and one biochemical parameter.
The most important experimental findings are:
1. More intensive interval (raining load has resulted in a greater decrease (degree of fatigue) in those muscular contractile capacities which form the physiological basis of muscle strength and speed. A continuous 6 km long run at a speed of 4.96 mis caused a larger deficiency in the parameters defining the basis of muscular endurance capacity.
2. The recovery of the force of muscle contraction (power) and biomechanical parameters of the speed of muscle contraction ix rapid and takes 10-15 minutes, while the recovery of muscle endurance is a slower process and takes 1 to 2 hours, similar as the processes of lactate elimination from blood.
3. Supercompensation of muscular contraction characteristics (power and speed of contraction) is attained in 10 up to 15 minutes after the run and is further maintained at least 40 minutes after the exertion.
