an increase in training volume at high intensity levels were related to injury incidence, or 6 increased the odds of injury. Training intensity was assessed through time spent in two high-7 and very high-intensity zones of 85-<90% and ≥90% of maximal heart rate (T-HI and T-VHI, 8 respectively), and all injuries were recorded over two consecutive seasons. Twenty-three elite 9 professional male soccer players (meanSD age 25.64.6 years, stature 181.86.8 cm, and 10 body mass of 79.38.1 kg) were studied throughout the 2-yrs span of the investigation. The 11 results showed a mean of total injury incidence of 18.8 (95% CI 14.7 to 22.9) injuries per 1000 12 h of exposure. Significant correlations were found between training volume at high intensities
Muscle injuries are one of the most common sport related injuries, their incidence varying from 30-55% in all sports injuries. They account for the loss of 90 training days and 15 matches per club per season in elite football (soccer). In recent years, the use of Actovegin® in sports medicine has caused a lot of controversy in many sports disciplines. Although it is unlikely for this deproteinised substance to have oxygen-enhancing capacity, there is an anecdotal belief that Actovegin® can increase an athlete's performance. Actovegin® is produced by Nycomed Austria GmbH and has been used by doctors across Europe, China and Russia for over 60 years. Nevertheless, very little is known regarding the effects of Actovegin on muscle injuries. This article reviews the current evidence on Actovegin®, its legal status with sports governing bodies and its potential role in sport injuries. We will also report our experience with this drug in treating muscle injuries. In this pilot study, players in the Actovegin treatment group were able to return to play 8 days earlier (95% CI -1.249 to -14.7510) compared to physiotherapy alone (p=0.033). No adverse reactions were recorded in any of the participants.
Talonavicular coalitions, a rarely reported fusion between the talus and navicular, are often an incidental radiographic finding that may be asymptomatic or associated with peroneal spasm. The authors present a review of literature and case report based on clinical evaluation and instrumented gait analysis. Specifically, a patient presenting with a bilateral talonavicular coalition was objectively evaluated with kinetic, kinematic, muscle dynamometry, and pedobarographic testing to understand the biomechanical limitations related to this pathology. An excessive passive component of ankle torque, a high first metatarsophangeal joint plantar pressure, and a diminished time in the midstance portion of stance phase were measured and compared to those of healthy individuals.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
