Subsequently, the participant was asked to perform a series of standardized strength and aerobic exercise activities (see "Standardized Exercise Protocols").
The exercise protocol (section "Standardized Exercise Protocols") was always performed under supervision of two researchers to ensure proper execution.
On day 2, standardized exercise protocols were carried out before each questionnaire (i.e., a strength exercise protocol before the strength exercise questions, and an aerobic exercise protocol before the questions about aerobic activities).
Standardized exercise training with prescribed work-rest ratios, intensity, volume and time are more effective in improving physical fitness, especially short term [ 23, 32, 33].
CPET was then performed as a multistage incremental "ramp workload" study using a cycle ergometer and a metabolic cart with standardized exercise software (Medgraphic Cardio-2CP system, Medical Graphics Corporation, St. Paul, MN, USA) for breath-by-breath analysis of gas exchange.
Factors determining clinical success other than measuring technical skills on this simulator were taken into account, but in this study we minimized bias and standardized the exercise to validate the simulator.
In summary, it can be concluded that a standardized physical exercise with increasing intensity leads to an increase in IMP concentration in red blood cells immediately after exercise, which with a significant increase in Hyp concentration in the blood suggests that Hyp was included in the IMP pool.
We have shown in this study that a standardized physical exercise with increasing intensity leads to an increase in IMP concentration in red blood cells immediately after the exercise, which with a significant increase in Hyp concentration in the blood suggests that Hyp was included in the IMP pool.
We implanted telemetric ECG transmitters (DSI, St Paul, MN, USA) and recorded telemetric ECGs during normal activity for 24 h, standardized swimming exercise, and repetitive warm air jet challenges at baseline, after 5 days of chronic β1-β2-adrenoceptor-blocker propranolol (propranololhydrochloride) 3.5 mg/day per os (p.o).
