“…Confirming our first research question, one of the main findings is that agility and COD differ also in fatigued conditions (Fig 4), with a slight but constantly increasing effect size compared to rest conditions (ES between 1 st blocks = 2.02; ES between 2 nd blocks = 2.3; ES between 3 rd blocks = 2.38; ES between 4 th blocks = 2.7). This is a novel finding because previous studies only investigated RCOD [29][30][31][32] and RA [33,34] separately.…”

“…For instance, Ruscello et al [31] reported a performance decrement of 5.76% in RCOD ability using the index of fatigue (IF%) as a measure (see [26] for direct comparison between methods and formulas) and adopting a 1:5 work:rest ratio. On the contrary, Matla ´k et al [33], using always a 1:5 work: rest ratio, but with a very different spatial configuration (less distance per repetition, and different turn angles), reported no clear trend of fatigue during one RA protocol. Furthermore, Madueno et al [32] showed that active recoveries between RCOD repetitions causes superior physiological stress, leading to a higher performance decrement, compared to passive recoveries.…”

“…block organization was also adopted by Matla ´k et al [33] in their study on repeated agility. By doing so, it would be possible to see a clearer performance trend between the initial (no fatigue) and final blocks (fatigue), avoiding the risk of an inter-repetition high variability.…”

“…However, in situational team sports like soccer, more than the single best performance, the ability to perform repeated efforts with only partial recoveries, then under the influence of fatigue, is the real crucial aspect, since players are required to resist it and to keep on playing in such condition. For this reason, research has focused on tasks with high intensity efforts interspersed with short recovery periods, like the repeated sprint ability (RSA) [26][27][28], the repeated change of direction (RCOD) ability [29][30][31][32], and very few also on repeated agility (RA) ability [33,34], even if a definition of this term is still missing. Moreover, the work:rest ratios of these repeated tasks, aimed to test players' ability to perform several high intensity activities resisting to fatigue, typically range from 1:2 to 1:6, also according to the sport practiced, but a 1:5 ratio is usually adopted [26,28,31,35].…”

Agility and change of direction speed are two different abilities, but no study has investigated if this difference exists also in fatigued conditions, and whether fatigue develops in a different way in a repeated-trial scenario. Fourteen soccer players (age: 17.0 ± 0.4 yrs; height: 176.9 ± 6.5 cm; body mass: 69.2 ± 6.4 kg) competing in a national-level youth league completed in a randomized counter-balanced crossover design a repeated agility protocol (RA) and a repeated change-of-direction one (RCOD), both consisting in performing 20 consecutive repetitions (work:rest ratio 1:5). The 20 repetitions were divided into 4 blocks (each block containing 5 repetitions) for the analysis. Results show that agility and COD are two different abilities both in rest and fatigue conditions: block 1 RA vs 1 RCOD (p < 0.001; ES = 2.02 huge; r = 0.17 poor; r2 = 0.03), 2 RA vs 2 RCOD (p < 0.001; ES = 2.3 huge; r = 0.51 fair; r2 = 0.26), 3 RA vs 3 RCOD (p < 0.001; ES = 2.38 huge; r = 0.54 fair; r2 = 0.29), and 4 RA vs 4 RCOD (p < 0.001; ES = 2.7 huge; r = 0.41 fair; r2 = 0.17). However, the fatigue development in both conditions was similar, with a percentage decrement score (Sdec) of 7.5% for RA, and 7.3% for RCOD. Ratings of perceived exertions (RPE) were similar too (7.3 ± 1.7, and 6.6 ± 1.9, for RA and RCOD, respectively). However, a significant fatigue-related performance impairment arose earlier in RA (block 2) than in RCOD (block 3). Total RA and total RCOD times were significantly different (p < 0.001; ES = 2.65 huge; r = 0.41 fair; r2 = 0.17), suggesting that they are two different and independent abilities.

“…Modern football evolves rapidly, especially regarding the physical qualities [10,11]. This is because the football game involves many dynamic movements, including acceleration, deceleration and change of direction while running [12], and the speed in football means chasing the ball from back to front, then fast backward, leftward, rightward movements, returning to the centre of the field and dribbling and hitting the ball [13]. This is the reason why each player's dribbling or changing direction in several directions (chaotic) can be determined by the combined asymmetrical and unpredictable nature of football [14,15].…”

Football game requires a permanent dynamic, in which players frequently perform changes of direction, with or without the ball. This requires explosive strength in the lower limbs as well as agility. The aim of the study was to measure the execution time within the changes of direction over different distances. A total of 20 male football players were selected (aged 17.6±1.27 years old), BMI 21.4 ± 1.99. For the explosive strength, two tests using Optojump (Microgate) were applied: CMJ and 5 jumps single leg left/right front/back drift. Each player also performed an agility test consisting of a single change of direction to the left and another one to the right, then a complete turn with three changes of direction, once to the left and once to the right. Regardless of the dominant part, in the simple agility test there were no significant differences between the left and right leg (p> 0.05), while in the multiple tests, these differences became significant, with a delay in execution on the left side (p<0.05). Also, a moderate correlation was found between explosive strength and agility (r=.544, p<.05). In the games of possession, positioning and rounds, they will be permanently changed in such a way as to use both legs for the symmetrical development of explosive strength. Technical elements with and without the ball will be introduced in all situations, such as: quick jump-departure with the ball at the foot and change of direction to the left and to the right. Players will play positioning roles opposite to the situation in which they normally work (left defenders will be used on the right side, etc.). In all cases, it is recommended to insist on avoiding additional movements that lead to a decrease in agility.

The study aimed to determine the effect of reactive agility with the FITLIGHT training system on the speed of the visual reaction time and dribbling skill of basketball players. Participants were divided into an experimental group (n = 10; age, 14.80 ± 0.79 years; height, 163.80 ± 3.46 cm; weight, 55.90 ± 0.99 kg; training, 4.50 ± 0.53 years) and a control group (n = 10; age, 14.60 ± 0.70 years; height, 163.30 ± 3.47 cm; weight, 56.10 ± 0.74 kg; training, 4.30 ± 0.48 years). Reactive agility was assessed through a modified t-test, visual reaction time was assessed using the Li Lafayette instrument Visual Reaction Time Apparatus 63014 response panel, and dribbling skills were assessed through dribbling testing. The results showed improved agility through the modified agility t-test (11%; p = 0.001), an increased speed of visual reaction time for both the right and left hands (23–31%), and improved dribbling skills (19%; p = 0.001) for the experimental group using the FITLIGHT reactive agility software. The results also showed increased skills of the experimental group when compared to the control group. Differences in variability emerged between 6 and 14.1% in favor of the experimental group. Therefore, the researchers recommended that attention should be paid to activating the role of the FITLIGHT reactive agility training to improve and develop the physical, visual, and skill capabilities of basketball players. The researchers propose that FITLIGHT can be effectively used in the basketball training process.
