A Study of Blood Lactic Acid and Isokinetic Muscular Strength after Maximal Load Exercise

Abstract

Abstract. [Purpose] This study was undertaken to understand the effects of three different ways of resting after maximal exercise on lactic acid in blood, and muscular strength.[Methods] To achieve this objective, nine athletes were selected as blood donors. Blood was gathered from each donor at three different times: at rest, after maximal exercise, and after recovery. Strength was measured after 30 minutes maximal exercise.[Results] Lactic acid of significant differences appeared more in the walking + jogging rest than the national gymnastics rest and was more effective in removing lactate.[Conclusion] Isokinetic strength (Peak Torque, Peak Torque % Body Weight) were significantly better after the walking + jogging rest than after the national gymnastics rest.

Dehydration, skeletal muscle damage and inflammation before the competitions among the elite wrestlers

“…In clinical practice, CK, LDH, AST, ALT were commonly used for the diagnosis of skeletal muscle diseases and skeletal muscle tissue damage 42 ) . The most important indicator of muscle tissue damage is the serum CK level 43 ) . The LDH level is accepted to be a specific indicator of fatigue 44 , 45 ) .…”

Influence of preliminary exercise training on muscle damage indices in rats after one bout of prolonged treadmill exercise

“…CK and LDH are the metabolites produced within the human body during exercise, and an increase in exercise intensity and duration is known to result in a substantial corresponding increase in cardiac and skeletal muscle activity. The serum CK level is the most important indicator of muscle tissue damage 10 ) , while the LDH level is a specific indicator of fatigue 11 , 12 ) . In addition, the level of hs-CRP, an acute inflammatory marker, increases rapidly after exercise 13 ) .…”
