Is occlusion training effective in increasing strength and hypertrophy of lower limb muscles in MMA fighters?

BACKGROUND: The aim of this study is to evaluate the influence of implementation of the BFR training on the hypertrophy and strength of the lower limb muscles in combat sports fighters, using common and easy to perform both training and control methods. METHODS: Design as a randomized control trial (RCT). The study included 30 men, MMA fighters since at least a year. They were divided into two groups: (A, a control group; B, men with the BFR training). The training lasted 8 weeks (3 times a week) and consisted of performing a set of specific exercises with a load of 20% 1RM. RESULTS: The Wilcoxon analyzing test showed important changes in muscle girth (P<0.01) and lower limb muscular strength (P<0.05). These changes were to be seen in the tested group only, not in the control group. CONCLUSIONS: Occlusion training is effective in increasing strength and hypertrophy of lower limb muscles in martial arts fighters.

Uncommon Bone Injuries in Soccer Players.

Soccer is the most common team sport in the world. A significant number of players are associated with a large number of injuries. Injuries occur in a variety of contexts regardless of the age or performance level of players. The vast majority of injuries involve soft tissues. Bone injuries are less common, but usually result in long-term exclusion from the game. Three different types of fractures related to soccer are classified as acute types, stress fractures and avulsion. This manuscript outlines the diagnostic procedures and treatments for stress fractures, avulsion fractures and bone cyst. The common feature of the described injuries includes frequent difficulties associated with the correct diagnosis and treatment direction. In therapeutic treatment, the doctor and the patient often have to choose between conservative treatment and surgical treatment, which in many cases is not simple. We suggest that in the event of injuries to soccer players, surgical treatment should be used, shortening the time to return to full sports activity. A very important element of the therapeutic process is proper rehabilitation, which should be individually tailored to the patient in order to optimize the treatment process. Some of the rehabilitation protocols should be permanently incorporated into the warm-up protocols for training. Such a procedure has a preventive effect.

The Fifth Metatarsal Bone Fracture in Athletes - Modalities of Treatment Related to Agility in Soccer Players.

The 5th metatarsal fracture is a common foot fracture which could exclude a player from competition for several months and significantly affect his or her career. This manuscript presents the treatment and rehabilitation of professional soccer players who had acute fractures of the 5th metatarsal bone and a cannulated screw fixation. The main purpose of the analysis was to determine the minimum time necessary for a permanent return to the sport after a 5th metatarsal fracture among professional soccer players. We followed the surgical and rehabilitation path of 21 professional soccer players from the Polish League (Ist and IInd divisions) who suffered from the 5th metatarsal bone fracture. All players underwent standard percutaneous internal fixation with the use of cannulated screws. The total inability to play lasted for 9.2 (± 1.86) weeks among players treated only surgically (n = 10), 17.5 (± 2.5) weeks in the conservative and later surgery group, excluding players with nonunion (n = 6), and 24.5 (± 10.5) weeks for nonunion and switch treatment (n = 4) players. Prompt fracture stabilization surgery is recommended for athletes, enabling the implementation of an aggressive rehabilitation protocol as soon as possible. Early limb loading after surgery (from week 2) does not delay fracture healing or hinder the bone union, thus rehabilitation plays a crucial role in shortening the time of RTP (return to play) and is obligatory for each athlete who undergoes surgical treatment.
