biochemical and performance recovery following simulated soccer match play",
abstract="The	aim	of	this	study	was	to	examine	the	effect	of	breathing	a hyperoxic	gas	mixture	on	recovery	kinetics	after	a simulated	soccer	match	protocol.	In	a double-blind,	randomized	design,	twenty-eight	semiprofessional	soccer	players	completed	the	Loughborough	Intermittent	Shuttle	Test	(LIST)	followed	by	the	administration	of	either	a hyperoxic	(FIO2 =	99.5%:	HYP)	or	a normoxic	gas	mixture	(FIO2 =	21%:	NORM).	HYP	and	NORM	were	administered	immediately	after	LIST	and	daily	for	the	next	3 days	for	15 minutes.	Physical	performance	(squat	jump:	SJ,	countermovement	jump:	CMJ,	maximal	voluntary	contraction:	MVC,	and	20 m sprint:	SP),	blood	concentrations	of	muscle	damage	markers	(creatine	kinase:	CK,	lactate	dehydrogenase:	LDH),	marker	of	inflammation	(C-reactive	protein:	CRP)	and	Hooper	index	(HI)	were	assessed	at	baseline,	15 minutes	and	24 h,	48 h and	72 h following	the	LIST.	SJ,	CMJ,	MVC,	and	SP	were	lower	at	15 min,	24 h,	and	48 h in	both	conditions	compared	to	the	prior	LIST	(p < 0.05).	However,	the	decrease	in	MVC	was	significantly	attenuated	at	15 min,	24 h and	48 h in	HYP	compared	to	the	NORM	condition	(p < 0.01).	Likewise,	HI,	muscle	soreness	and	fatigue	scores	were	significantly	lower	in	HYP	compared	to	the	NORM	condition	up	to	48 h following	the	LIST	(p < 0.01).	The	present	study	suggests	that	the	application	of	HYP	immediately	after	a simulated	soccer	match	and	for	the	next	3 days	promoted	a lower	fatigue-induced	decrement	in	MVC	and	restored	perceptual	parameters	of	fatigue	in	semi-professional	players.",
