			 Nicknamed "Blade Jumper", the 2012 Paralympics gold medalist and 
			2014 German long jump champion hopes to become the second athlete 
			with a carbon fiber running blade to compete in the Olympics after 
			South Africa's Oscar Pistorius in 2012. 
 But a new rule by the International Association of Athletics 
			Federations (IAAF) introduced last year leaves it to amputee 
			competitors to prove their prosthesis does not put them in an 
			advantage over able-bodied athletes.
 
 "Markus Rehm and the German Disabled Sports Association hope to gain 
			clarification from the results about whether it will be possible in 
			the future for athletes with amputations to compete at national and 
			international athletics competitions," his management said in a 
			statement on Tuesday.
 
			
			 "The results will be presented at the beginning of June in Cologne."
 The studies are conducted in association with the German Sport 
			University Cologne, the National Institute of Advanced Industrial 
			Science and Technology in Tokyo, the University of Colorado Boulder 
			as well as a Japanese broadcaster.
 
 IAAF's new rule bans 'the use of any mechanical aid, unless the 
			athlete can establish on the balance of probabilities that the use 
			of such an aid would not provide him with an overall competitive 
			advantage over an athlete not using such aid.'
 
 Rehm's performances have caused a stir, especially after his 2014 
			German title victory that triggered mixed reactions from fellow 
			athletes at the time.

			He also beat able-bodied athletes with a jump of 8.10 meters at the 
			Glasgow Indoor Grand Prix in February.
 The 27-year-old, who lost his lower right leg in a boating accident 
			as a teenager, has already complained his case was dragging on, with 
			the IAAF still to publish the specific criteria for their new rule.
 
 Rehm, who under the current rule is at the moment unavailable for 
			selection for the German Olympic team, has also threatened legal 
			action as a last resort if the IAAF was seen to be stalling his 
			case.
 
 The Rio Olympics begin on Aug. 5, with the long jump qualifying and 
			final competitions set for Aug. 12-13.
