COMPRESSION OVERVIEW:

INCREASED VO₂MAX AND ANAEROBIC THRESHOLD

Recent research in trained athletes reported that compression garments increased VO₂max by 10% and anaerobic threshold by 40% (13). Given that these two physiological variables are highly correlated to success in endurance sports compression garments may provide a significant competitive advantage for endurance athletes.

REDUCED MUSCLE OSCILLATION

It has been suggested that excess oscillatory displacement of a muscle during a dynamic movement may contribute to fatigue and interfere with neurotransmission and optimal muscle recruitment patterns (14). Recent research reported that compression garments were able to significantly reduce longitudinal and anterior-posterior muscle oscillation by 0.32 and 0.40cm respectively upon landing from a maximal vertical jump (7).

ENHANCED PROPRIOCEPTION

Proprioception or joint position sense has major implications to athletic performance, particularly in the areas of technique and injury prevention. Research investigating hip joint proprioception reported significantly greater joint position sense at both 45 and 60 degrees hip flexion (11).

INCREASED EXPLOSIVE MUSCULAR POWER

Explosive muscular power is highly correlated with success in most sports. Research in track and field athletes has reported a 5.2% increase in maximal vertical jump height when vertical jumps are measured wearing compression garments (7).

REDUCED BLOOD LACTATE CONCENTRATIONS

High intensity exercise produces lactic acid which presents a challenge to the body’s ability to maintain pH within the narrow physiological range. This in turn can negatively impact the force generating capacity of the muscle which results in muscle fatigue and impaired athletic performance. Data published by Berry and McMurray (1) showed a 14% decrease in blood lactate concentrations 15 minutes following high intensity exercise when compression garments were worn during and after exercise.

FASTER RECOVERY

Muscle damage is an inevitable consequence of high intensity exercise and any technique that can facilitate muscle repair and faster recovery is of large benefit to the athlete. A study in elite Rugby Union players reported that compression garments worn immediately after a rugby match significantly reduced markers of muscle damage (creatine kinase) compared to passive recovery at 36 and 84 hours post match (8)
