ABSTRACT Introduction: Brain-Derived Neurotrophic Factor (BDNF) plays an important role in transmission of nerve impulses, plasticity, growth, and generally in the health of nervous system. Interleukin-6 (IL-6) is involved in immune and inflammatory responses and is produced by immune cells, fibroblasts, endothelial cells, skeletal muscles, and fat tissues. The aim of this study ...

Purpose: Despite the widespread use of cryotherapy in sports fields there is a lack of certain evidence of its impact of it on muscle activation especially following fatigue-induced exercise. This study aimed to assess the impact of cryotherapy alone and after plyometric exercises on knee muscle activation during the drop jump task. Method: 35 active female subjects (mean age of 22.74±2.10, m...

Plyometric training has become an important part of upper extremity rehabilitation protocols. The purpose of this study was to determine the effects of plyometric training on the shoulder internal rotators (IR). Male subjects (N=34) were randomly divided into two groups: control or plyometric training. Pre/interim/posttesting measurements included: 1) kinesthetic measurements of shoulder IR at ...

Non-sport-specific strength training is a way to increase endurance performance; however, which kind of exercise (maximal, plyometric, explosive or resistance training) gives the best results still under debate. Scientific publications were analyzed according PRISMA checklist and statement. The initial search yielded 500 studies, 17 included in this review using PEDro Scale. Maximal boosted abi...

Background Core stability is the central motor control and muscular capacity of the lumbar-pelvic-thigh to maintain stability of this region against various postural and external forces [1]. Studies, have been shown different roles of core stability to improve performance; Lewarchik (2003) tend to stabilize the core in footballers not observed significant using the stability exercise program an...

ACL injury continues to be the largest single problem in orthopedic sports medicine, with approximately 95,000 new injuries occurring every year. Non-contact mechanisms represent 80% of the traumatic events resulting in more than 2000 ACL injuries per years between young athletes aged 14–23 years. Acceleration, deceleration, change of direction, landing and pivoting are the most common mechanis...

The purpose of this meta-analysis was to attempt to gain a clear picture of the magnitude of sprint performance improvements expected after chronic plyometric training (PT) and to identify specific factors that influence the treatment effects. Studies employing a PT intervention and containing data necessary to calculate effect size (ES) were included in the analysis. A total of 26 studies with...
