“…After finishing the jump tests, a re-warm-up for the COD started, which consisted of performing the test at sub-maximal intensities (50%, 70% and 90% of self-perceived maximum intensity). Pauses of one to two minutes were included between each run during the re-warm-up, where the athlete performed rotational movements from a protocol by Van den Tillaar; Lerberg; von Heimburg [60]. Then the COD test was performed with maximal intensity, with three minutes' rest between each run.…”

The ability to rapidly perform change of direction (COD) is crucial for performance in Soccer. COD speed is thought to share similarities with countermovement jumps in kinematics and muscle activation. Thus, the objective of the current study was to investigate the relationship between muscle activities in performance measures of a modified 505-agility test and different countermovement jumps. Twenty-one experienced soccer players performed a COD test including the 505-agility test and uni- and bi-lateral horizontal and vertical countermovement jumps. The main findings were that the vertical bilateral and horizontal unilateral countermovement jump were able to predict total time to complete the COD, but not 505-agility time. Muscle activity in the COD and countermovement jumps was only distinguished by a higher peak muscle activity for the adductor longus, semitendinosus and biceps femoris in the COD to stabilize the hip and decelerate knee joint movements when turning compared with the jumps. Conclusively, the relationship between performance in countermovement jumps and total time to complete the COD test was due to longer sprint distances, which makes the distinction between performances bigger. Peak muscle activity of most muscles is similar between the jumps and the COD step, indicating similar muscular demands between these activities.

“…Another study has evaluated the influence of specific and general warm-ups on explosive muscular performance [35], resulting that only those pertinent to explosive strength provided additional value to the muscular outcomes. This aspect has also been highlighted by van den Tillaar et al, [36], who also stressed that during a warm-up, specificity should be preferred rather than duration. There may be a twofold explanation on why the LSR did not show an increase in the ESA group: Firstly, no specificity was provided regarding aerobic activity.…”

“…Secondly, the duration of the warm-up activity was too long causing negative effects on the aerobic outcomes in the sampled population. Therefore, coaches should not provide excessively long warm-ups [36].…”

Background: Physical fitness in youth is a predictor of health in adulthood. The main objective of the present study was to understand if an enriched sport activity program could increase physical fitness in a population of schoolchildren. Methods: In a sample of 672 children aged 10.0 ± 1.90 years, different motor skills were tested by the 1 kg and 3 kg ball throw (BT), the standing broad jump (SBJ), the 30 m sprint (30mS), the leger shuttle run (LSR), the illinois agility test (IGT), and the quadruped test (QT). Within the controlled-trial, the intervention group (ESA) underwent an additional warm-up protocol, which included cognitive enhancing elements, for 14 weeks while the control group continued with ordinary exercise activity. Results: A significant increase was present regarding the 1 kg and 3 kg BT, the SBJ, the 30mS, and the IGT, while no significant difference was shown regarding the QT and the LSR in the ESA group between pre and post intervention. In the control group, no differences were present for any test except for the QT and the LSR post-test. Conclusion: A 14-week structured physical intervention had moderate effects regarding throwing, jumping, sprinting, and agility in a sample of schoolchildren.

26This study aimed to study the co-activation of hamstring-quadriceps muscles 27 during submaximal strength exercises without the use of maximum voluntary isometric 28 contraction testing and compare (i) the inter-limb differences in muscle activation, (iithe 29 intra-muscular group activation pattern, and (iii) the activation during different phases of 30 the exercise. Muscle activation was recorded by surface electromyography of 19 elite 31 male youth players. Participants performed five repetitions of the Bulgarian squat, lunge 32 and the squat with an external load of 10 kg. Electrical activity was recorded for the rectus 33 femoris, vastus medialis, vastus lateralis, biceps femoris and semitendinosus. No 34 significant inter-limb differences were found (F 1, 13 =619; p=0.82; partial η 2 =0.045). 35 Significant differences were found in the muscle activation between different muscles 36 within the muscle group (quadriceps and hamstrings) for each of the exercises : Bulgarian 37 squat (F 1,18 =331: p<0.001; partial η 2 =0.80), lunge (F 4,72 =114.5; p<0.001; partial η 2 =0.86) 38 and squat (F 1,16 =247.31; p<0.001; partial η 2 =0.93).Differences were found between the 39 concentric, isometric and eccentric phases of each of the exercises (F 2, 26 =52.27; p=0.02;40 partial η 2 =0.80). The existence of an activation pattern of each of the muscles in the three 41 proposed exercises could be used for muscle assessment and as a tool for injury recovery. Introduction 43Performance in soccer depends on psychological, physiological and 44 biomechanical factors (1, 2). The study of these factors not only helps improve 45 performance, but also works towards injury prevention. Performance and injury 46 prevention are not isolated fields, and the presence of an injury can affect on-field 47 performance. Measurement of the muscular capacity of players is an important factor in 48 the evaluation and prediction of the functional capacity of the player (3). 49Muscular capacity has been traditionally measured using isokinetic machines (4, 50 5). However, recently many studies have used electromyography (EMG) (6-8). One of 51 the major aims of such studies has been to to determine asymmetry in soccer players, 52 which can affect both performance (9, 10) and injury (11). Such comparative studies have 53 been carried out in youth soccer players as well (12-15) finding that there may be a 54 neuromuscular pattern and that force work could be related to a reduction in the injury 55 rate in football players. 56 Asymmetry in soccer players could be offset with proper exercise prescription, 57 which facilitates improvements in musculoskeletal function by addressing the specific 58 needs of the subject as an integral part of any rehabilitative, preventive, or maintenance 59 program (16). Functional weight-bearing exercises have received a significant amount of 60 attention as the preferred mode of exercise for lower extremity strengthening (17). In 61 studies with EMG, basic strength exercises (forward lunge, bugarian squat, lateral ste...
