“…Similar to the differences described for locomotor movement rates between top and bottom teams in FIFA Women's World Cup (Bradley and Scott, 2020) there are likely variations in the tempo of play across NCAA Division I that could subsequently impact energetic demands of these matches. Furthermore, the implementation of the metabolic power methodology could be modified by commercially available GPS systems (Williams et al, 2019) in order to have a proprietary competitive advantage, which could have also influenced the reported outcomes between studies (Terziotti et al, 2018). Additionally, when converting the relative energetic demands from these studies into calorie expenditure (520-770 kcal) (Wells et al, 2015;Williams et al, 2019), they are substantially lower than values obtained using heart rate derived equivalents (∼1,100-1,400 kcal) (Jagim et al, 2020;McFadden et al, 2020), thus it does not appear the outcomes from various methods can be used interchangeably.…”

Female soccer players are exposed to specific physical demands during matches, which vary according to the standard of play. Existing studies have largely focused on quantifying the distances covered for professional and international level players. This approach is limited in scope regarding the broader aspects around physical demands and is detached from development pathway models. An understanding of the demands across all standards will provide valuable insights about appropriate player development and help ensure physical readiness for the demands of the sport. The aim of this perspective paper is to describe the physical demands experienced during women's soccer matches across the developmental spectrum. A combination of evidence from the literature and data from the author's research (JDV) is presented. Specifically highlighted are the trends for locomotor distances, acceleration and deceleration frequency, and metabolic power metrics for youth (≤U17), college (NCAA/U20), professional (domestic) and international standards of women's soccer. In addition, the changes in match demands between levels of play are used to help illustrate gaps that must be overcome in order to successfully achieve physical readiness to compete at higher levels. The evidence demonstrates the importance of training appropriate attributes to prepare female soccer players who are striving to play at progressively higher standards.

“…In addition to the sampling frequency of the device (10Hz), the accuracy of positioning measurement and its derivatives is influenced by other factors. The most important of these include the number of satellites connected and their horizontal dilution of precision (HDOP) [22,23]. HDOP values >1 are defined as ideal, while values >2 are defined as excellent [24].…”

Assessment of Pain and External Load in Amputee Football Using Digital Pain Drawing and GNSS Tracking—A Pilot Study

et al. 2022

Amputee Football (AF) players move using lofstrand crutches (LC) and a single leg during training and matches, which may expose them to excessive loads. Due to a lack of scientific articles describing these issues, this pilot study aims to gain insight into the assessment of pain experiences, as well as external loads during training and matches in AF. An observational study design was followed. Twelve male AF players (2 goalkeepers—GK and 10 field players—FP), 29.9 ± 8.7 years, stature 178.3 ± 6.5 cm, body mass 77.2 ± 8.9 kg were involved in the study. After stature and body mass measures, participants filled out the questionnaire for pain. The players were familiarized with digital pain drawing (DPD). Afterwards, they reported pain typically felt in relation to regular AF training and playing matches—recall pain (RP). During a two-day training camp (TC) with two training sessions each day and during a two-day international tournament (IT) with two matches each day, the players were monitored using DPD, rate of perceived exertion (RPE) and overall pain level (OPL) scales. In addition, during an international tournament (IT), match players were monitored using a GNSS tracking system for external load assessment. All of the participants reported multiple locations of pain after AF training or a match. The area of recall pain (RP) was the highest: +0.5% when compared to the end of TC and +43% when compared to end of IT. The pain area registered at the end of IT was significantly lower (p = 0.028) compared to RP and lower without statistical significance when compared to the end of TC. Average RPE was 3.31 ± 1.38 and average OPL was 2.86 ± 1.81 in 0–10 scale. Typical RPE was higher than that registered at the end of IT. Also typical OPL was higher compared to that registered after the end of TC, which was higher than after the end of IT. The average distance covered by a FP during a match ranged from 2483.14 ± 583.64 m to 2911.08 ± 828.90 m. AF field players suffered pain as a consequence of training and matches. The loads coming from playing and training, combined with pain, may lead to injuries. Further research directions should include assessments of the relationship of pain characteristics, injuries and GNSS tracking parameters.

“…Global positioning system-technology has proven to be a valid and reliable tool for daily monitoring of the training load and match load on professional soccer players (21,22,29). Although the accuracy of GPEXE Pro is diminished in actions involving higher speeds or changes of direction (37); its reliability and validity have been tested and verified recently (18). The players were fitted with these devices 15 minutes before the activity to avoid possible errors or delays for the GPS9 activation.…”

Analysis of the competitive weekly-microcycle in elite soccer: comparison of workload behavior in absolute and relative terms. J Strength Cond Res 37(2): [343][344][345][346][347][348][349][350] 2023-This study aimed to analyze the locomotion activity of elite-level soccer players throughout the weekly microcycle by playing position, and compare the training-load (TL) behavior in relation to match-play in absolute and relative (meters or events per minute) terms. Training and match data were collected from 30 professional soccer players belonging to a Spanish First Division team during the 2015/2016 season using global positioning technology (152 training sessions and 38 matches). Overall, the results showed a decrease of TL metrics when competition approached (p , 0.05). However, a progressive decrease was not found for all metrics. Two-way analysis of variance test revealed that workload was affected by the interaction between microcycle-day and season period showing medium or large effect size (h 2 p . 0.15) for all positions and metrics. Considering the TL in relation to the match-load, opposite load behavior was found in absolute and relative terms by position; whereas, central-defenders, external-defenders, and forwards covered 21, 25 and 26% more absolute medium-speed running distance (MSRD), respectively; central-defenders covered 14% (8.6-13.4 m•min 21 ), external-defenders 10% (7.5-13.9 m•min 2 1 ), and forwards 7% (8.4-15.7 m•min 21 ) more relative-MSRD 4 days before match than match-day. The accelerations-metric also showed higher relative values 4, 3, and 2 days before the match. Because the objective of the training is to prepare players to withstand the competition demands, analyzing the position-specific TL concerning to match demands represents an advantageous strategy for training periodization. In addition, this study highlights the importance of taking into account the time spent of developing the different efforts to properly define the position-specific physical demands.
