Effect of 12-Week Functional Training Intervention on the Speed of Young Footballers

Abstract

The aim of the research was to verify the functional state of young football players using selected tests of the Functional Movement Screen (FMS) protocol, as well as the impact of the 12 weeks of functional training on the speed parameters. The research was conducted on 20 highly competitive young (U17) football players. Research project was conducted in two stages: in the first part of the study, the functional assessment was made by using the FMS test, then the measurement of the speed parameters was done with the Microgate photocells system. Results showed a significant improvement in the functional state of young football players: FMS 1 (45.2% of difference, p = 0.004), FMS 2 (24.3% of difference, p = 0.012), FMS 3 (48.5% of difference, p = 0.001). After the functional training program, there was also an improvement in the parameters of the acceleration and velocity: acceleration between 5-10 m and speed between 10-30 m shows significant improvement (expressed during covering a given distance) of the footballers, amounting to 0.02 s (2.4%) and 0.04 s (1.5%). But there was no improvement in acceleration between 0-5 m. An appropriate training schedule, based on FMS results, should be adopted in the annual training program to improve basic motor skills of the football players and minimize their injuries. software, A.S. and A.S.S.; validation, A.S., T.G. and A.S.S.; formal analysis, A.S. and A.S.S.; investigation, J.B., A.B. and A.S.; resources, J.B., A.B. and A.S.; data curation, A.S. and A.S.S.; writing-original draft preparation, J.B., A.B. and A.S.; writing-review and editing, A.S., T.G. and A.S.S.; visualization, A.S.; supervision, A.S.; project administration, A.S.; funding acquisition, A.S.

Effects of functional correction training on injury risk of athletes: a systematic review and meta-analysis

“…Three studies were not included in the meta-analysis for the following reasons: one was missing data regarding the total FMS™ scores and sports injury but included data regarding the strength and flexibility of the athletes ( Song et al., 2014 ), and two studies had single-group sample sizes fewer than 10 people and very low quality assessment scores (the PEDro quality scale score for physical therapy was only 4 points) ( Kim et al., 2014 ; Armstrong et al., 2019 ). Furthermore, some studies used a single-group pre-test design method to perform functional correction training for athletes and found that that they had a positive impact on the FMS™ scores, asymmetric events, and sports injuries ( Kiesel, Plisky & Butler, 2011 ; Lee, Zhang1 & Lee, 2015 ; Garbenyté-Apolinskiené et al., 2018 ; Tejani et al., 2019 ; Boucher et al., 2018 ; Baron et al., 2019 ; Huebner et al., 2019 ; Bayrakdar, Kılın & Boz, 2020 ). These studies did not meet the inclusion criteria and were excluded from this report.…”

Distribution of Plantar Pressure in Soccer Players

“…It is foot defects that can alter gait biomechanics, resulting in the ineffective performance of motor activities and a significant load on the athletes’ locomotor system [ 2 ]. As one of the contact sports, soccer can lead to injuries, especially in the foot and ankle, amounting to 20% of all injuries [ 12 , 13 ]. According to Bastos et al and Baron et al, soccer players who play in defensive positions, with frequent contact with the opponent, those who run at full speed with changes in directions and those who perform rapid accelerations at their position on the pitch are particularly vulnerable to musculoskeletal injuries [ 5 , 13 ].…”

Improved performance, optimal preparation of players for performing sprints and changes of direction and reduced risk of injury can be achieved with properly designed warm-up routines before training and games [ 13 , 14 ].…”
