“…Speci cally, the A-S pro le (Table 1) for each player was obtained for each session and player from a dataset with the speed performed in each acceleration during the session. The aim of the A-S pro le is to identify the linear regression the maximal acceleration produced in any speed (15) . The A-S pro le was plotted following the instructions given by Morin, et al 15 .…”

“…The aim of the A-S pro le is to identify the linear regression the maximal acceleration produced in any speed (15) . The A-S pro le was plotted following the instructions given by Morin, et al 15 . The minimal speed considered for analysis was 3 m/s because below this value the accelerations are not considered as maximal.…”

“…Although the force-velocity pro le is usually measured by a single linear and eld test with good validity and reliability (15,16) it requires preparation, organization and it is not speci c to team sports actions (15) . Thus, Morin et al (2021) designed a new method, which is known as the acceleration-speed (A-S) pro le and it is based on an in-situ data collection. This implies that the data do not need to be collected from a speci c test since the raw acceleration and speed data collected during the training or match is enough.…”

“…The concept is close to the F-V pro le and it allows to extrapolate the theoretical maximal speed and accelerations as the individual's sprint maximal capacity (15) . Also, it has shown good reliability when evaluating elite football players (15) . Similar results correlate V 0 and F 0 (F-V pro le variables) to the maximal theoretical speed (S 0 ) and the maximal theoretical acceleration (A 0 ) (A-S pro le variables) respectively, representing both the same mechanical concept (15) .…”

The acceleration-speed profile (A-S profile) is a new method to evaluate physical and determinant capabilities such as acceleration (ACC) and speed (S) in sports. The aim of this study was to analyze the differences in the A-S profile of elite football players induced by playing position and microcycle day. Players belonged to a second division club of Spanish competition La Liga. They were classified into six playing positions: central defenders (CD), full backs (FB), midfielders (MF), wide midfielders (WMF) and forwards (FW). Data was collected along six microcycles including one match per microcycle. The variables analyzed included: maximal theoretical acceleration (A0), maximal theoretical speed (S0), maximal acceleration (ACCmax), maximal speed (Smax) and A-S slope (ASslope). Significance differences were found within positions and microcycle day for all variables (p<0.05). MD showed greater values than the training sessions in A0, ACCmax and Smax (p<0.05). Highest values for variables associated to acceleration capabilities were found in CD on MD, whereas speed variables were higher in WMF. MD-2 showed the lowest values in all variables except for ASslope. In conclusion, the results show that exist differences on the A-S profile depending on the playing position and the microcycle day. Assessing the A-S profile could help to individualize the training sessions depending on playing position demands and to check that competitions requirements are achieved during microcycle.

“…Thus, regular measurements throughout the season are likely more valuable to better inform the player on injury risk. This will also be of interest to analyze the normal variability of weekly or monthly sprint acceleration mechanical outputs and their relation to hamstring injury risk, for example, promising in situ approaches recently presented by Morin et al [52].…”

Clear decreases in horizontal force production capacity during sprint acceleration have been reported after hamstring injuries (HI) in football players. We hypothesized that lower FH0 is associated with a higher HI occurrence in football players. We aimed to analyze the association between sprint running horizontal force production capacities at low (FH0) and high (V0) velocities, and HI occurrence in football. This prospective cohort study included 284 football players over one season. All players performed 30 m field sprints at the beginning and different times during the season. Sprint velocity data were used to compute sprint mechanical properties. Players’ injury data were prospectively collected during the entire season. Cox regression analyses were performed using new HI as the outcome, and horizontal force production capacity (FH0 and V0) was used at the start of the season (model 1) and at each measurement time point within the season (model 2) as explanatory variables, adjusted for individual players’ (model 2) age, geographical group of players, height, body mass, and previous HI, with cumulative hours of football practice as the time scale. A total of 47 new HI (20% of all injuries) were observed in 38 out of 284 players (13%). There were no associations between FH0 and/or V0 values at the start of the season and new HI occurrence during the season (model 1). During the season, a total of 801 measurements were performed, from one to six per player. Lower measured FH0 values were significantly associated with a higher risk of sustaining HI within the weeks following sprint measurement (HR = 2.67 (95% CI: 1.51 to 4.73), p < 0.001) (model 2). In conclusion, low horizontal force production capacities at low velocity during early sprint acceleration (FH0) may be considered as a potential additional factor associated with HI risk in a comprehensive, multifactorial, and individualized approach.
