BRIEF REVIEW: FORCE AND VELOCITY OF UPPER LIMB STRIKES

B

The force with which an upper limb striking technique such as a punch is delivered with is a major determinant of the impact of the strike and its potential for damage and effectiveness. Previous research has shown greater levels of mean and maximum punching force in winning vs. losing boxing contestants. A great variety of different upper limb striking techniques exist across a range of...

BRIEF REVIEW: TIME TO LOSS OF CONSCIOUSNESS FOLLOWING A STROKE

B

Combative choking techniques (more accurately described as strangulations) are commonly used techniques in a wide range of combat sports and arts, as well as in law enforcement. The goal of a strangulation is to cause bilateral compression of the carotid artery and jugular vein, decreasing the cerebral perfusion pressure and leading to a loss of consciousness (LOC). An understanding of the likely...

BRIEF REVIEW: TAPERING IN MMA

B

Tapering refers to a systematic decrease in training load leading up to a competition, and is a common practice in most competitive sports. The goal of a taper is to dissipate fatigue while maintaining fitness, therefore maximising preparedness for the event. In most combat sports, the tapering process is confounded by the period leading up to an event also being a period of body mass reduction...

BRIEF REVIEW: Time Motion Assessment in Judo

B

Visual, non-automated time-motion analysis has been used as a method of analysing performance in both competition and training conditions in a variety of sports, including combat sports, and is thought to have some utility in detecting change in performance as a result of training interventions.  Two separate studies were conducted on high-level Brazilian judo athletes. The first study had 25...

BRIEF REVIEW: The physical demands of mixed martial arts: A narrative review using the ARMSS model to provide a hierarchy of evidence

B

Christopher Kirk , David R Clark , Carl Langan-Evans & James P Morton Journal of Sports Sciences 2020;23-1 BACKGROUND The optimal preparation for any sport depends in part on the known determinants of success and the methods employed to achieve these determinants. As mixed martial arts (MMA) is a relatively new sport, the research base related to its performance factors is still in its...

BRIEF REVIEW: Hip & Lumbar Range of Motion and Lower Back Pain

B

BACKGROUND Most musculoskeletal injury is multifaceted, with biomechanics, i.e. the way we move, one potential aspect that may lead to the occurrence of either a gradual-onset or acute-onset injury. It is thought that suboptimal biomechanics (tightness, weakness, impaired motor control etc.) in certain areas of the body may lean to increased mechanical load in other areas.  The prevalence of...

BRIEF REVIEW: Sport Psychology in Mixed Martial Arts

B

BACKGROUND  The effectiveness of sports psychology interventions, or “psychological skills training” has been demonstrated in many sports. The aim of this study was to perform a review of studies directly related to sports psychology in MMA.  METHODS The terms “mixed mart arts” and “ultimate fighting” were searched in combination with: “Psychology”, “Sport Psychology”, “Exercise Psychology”...

Measurement of Wrist Motion in the Punch

M

BACKGROUND  Hand and wrist injuries are the most commonly reported injuries in boxing. Previous studies have looked at shoulder and elbow joint angles in punching, but none have investigated movement at the wrist METHODS An 6-degree-of-freedom electromagnetic tracking system was used to measure wrist movement during punching, which was compared to a mechanical surrogate and static wrist angle...

SHORT REVIEW: How Effective is Rapid Weight Loss in MMA?

S

BACKGROUND  Rapid weight loss followed by rapid weight gain strategies are commonly employed by combat sports athletes of all disciplines. The amount of weight lost and subsequently gained is generally greater in MMA athletes than other combat athletes  Previous studies have shown the amount of weight regained to be predictive of success in judo, but not in boxing. One small study in MMA athletes...
