Outcome Measures
Primary Outcomes (2)
Creatine kinase
The level of creatine kinase is measured from a venous blood sample taken by a healthcare specialist. Samples are collected in 2.7 ml citrate vacuum tubes. Samples are immediately centrifuged at 1000 g for 15 min and then divided into 0.5 ml cryotubes and frozen at -80 °C. Samples are taken pre-exercise (baseline), post-exercise, and 2 h, 24 h and 48 h post-exercise. Creatine kinase is determined by ELISA method according to the manufacturer's instructions.
Change between values before and after 4 weeks of crossover.
Perceived muscle soreness
A visual analogue scale is used to subjectively assess lower limb muscle soreness. The visual analogue scale is represented by a 100 mm line marked 0 - no pain and 100 - worst imaginable pain. The subject is instructed to mark a point on the line corresponding to their perceived muscle soreness. Muscle soreness is assessed pre-exercise (baseline), post-exercise, and 2 h, 24 h and 48 h post-exercise.
Change between values before and after 4 weeks of crossover.
Secondary Outcomes (3)
Reactive strength index
Change between values before and after 4 weeks of crossover.
Malondialdehydes
Change between values before and after 4 weeks of crossover.
Interleukin-6
Change between values before and after 4 weeks of crossover.
Other Outcomes (5)
Heart rate
Change between values before and after 4 weeks of crossover.
Ventilation
Change between values before and after 4 weeks of crossover.
Oxygen uptake
Change between values before and after 4 weeks of crossover.
