Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Running economy	The cost of running (oxygen consumption) at different speeds	Changes from baseline at 15 days
Secondary	Time to exhaustion	Time that the athlete endured running until voluntarily ending the exercise	Changes from baseline at 15 days
Secondary	Muscle power	Ability to produce muscle power in a jump test	Changes from baseline at 15 days
Secondary	Muscle oxygenation	Saturation of O2 in the vastus lateralis during exercise	Changes from baseline at 15 days
Secondary	RPE	Rate of perceived exertion during the exercise	Changes from baseline at 15 days
Secondary	Running mechanics	Contact and flight time of each step during the exercise	Changes from baseline at 15 days
