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 be… Expand

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 reduced… Expand
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 in… Expand

In order to study the effects of different athletic backgrounds on exercise‐induced hormonal responses, serum testosterone, luteinizing hormone, follicle‐stimulating hormone and cortisol… Expand
Comparison of physiological strain and muscular performance of athletes during two intermittent running exercises at the velocity associated with VO2max.
The purpose of this study was to examine physiological strain and muscular performance responses of well trained athletes during two intermittent running exercise protocols at the velocity associated… Expand
Validation of Cut-Points for Evaluating the Intensity of Physical Activity with Accelerometry-Based Mean Amplitude Deviation (MAD)
Purpose Our recent study of three accelerometer brands in various ambulatory activities showed that the mean amplitude deviation (MAD) of the resultant acceleration signal performed best in… Expand
Comparison of three maximal anaerobic running test protocols in marathon runners, middle-distance runners and sprinters.
- T. Vuorimaa, K. Häkkinen, P. Vähäsöyrinki, H. Rusko
- International journal of sports medicine
- 1 July 1996
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 and… Expand
