Heart Rate and Exercise Intensity During Sports Activities
SummaryVariations in heart rate during exercise correlate with changes of exercise intensity and may be measured directly by radiotelemetry and continuous ECG recording. The heart rate can also beExpand

The effect of probiotics on respiratory infections and gastrointestinal symptoms during training in marathon runners.
Heavy exercise is associated with an increased risk of upper respiratory tract infections. Strenuous exercise also causes gastrointestinal (GI) symptoms. In previous studies probiotics have reducedExpand

Changes in force production, blood lactate and EMG activity in the 400-m sprint.
The neural activation (iEMG) and selected stride characteristics of six male sprinters were studied for 100-, 200-, 300- and 400-m experimental sprints, which were run according to the velocity inExpand

Effects of acute prolonged exercise on-serum and LDL oxidation and antioxidant defences.
We investigated the acute effects of long-distance running on oxidation of lipids and antioxidant functions in LDL and serum. Eight trained male runners who participated in a 31-km run and 22 maleExpand

Comparison of three maximal anaerobic running test protocols in marathon runners, middle-distance runners and sprinters.
Three modifications of the maximal anaerobic running test (MART) were compared in sprinters (Spr, n = 5), middle-distance runners (Mid, n = 5) and marathon runners (Mar, n = 6). The MART1, MART3 andExpand

Lack of association between indices of vitamin B1, B2, and B6 status and exercise-induced blood lactate in young adults.
By means of a 5-week vitamin B-complex supplementation, associations between indices of vitamin B1, B2, and B6 status (activation coefficients [AC] for erythrocyte transketolase, glutathioneExpand
