“…The DT group participated in more zone 3, 4, and 5 (moderate to heavy, heavy, and very heavy) impacts than all other defensive position groups, which may be Competitive Impact Profiles of NCAA Football Players 14 attributed to the physical demands of the DT position, often involving physical contact with numerous offensive players on each play throughout the course of competition.Comparing the findings of the present study with the existing knowledge of positional game demands is problematic due to the lack of research on impact profiles in American football players. Positional analysis in contact team-sport similar to American football, including Rugby League(18,21) and Rugby Union(3,5,20,26), have demonstrated inter-positional differences in the quantity and intensity of impacts associated with competition, supporting the findings of the present study. Although the influence of the number and intensity of impacts sustained during competition on the duration of post-game recovery in Rugby League players has been investigated(18,21), and the biochemical and endocrine responses to competitive games in American football and Rugby league players have been reported(15,22), there is a lack of research quantifying the relationship between the physical demands of competition and the time-course of recovery associated with college football games.…”

“…American football competition presents a unique model to study position-specific impact profiles that may be similar to other contact team-sports. The characteristics of repeated collisions and the associated blunt force trauma resulting from competition in Rugby League and Rugby Union players have been reported (3,5,18,21), and significant (p<0.05) inter-positional differences in total impacts experienced have been demonstrated during competition (20,26). However, uncertainty exists regarding the intensity and frequency of position-specific impact profiles of NCAA division I football players during competition.…”

Wellman, AD, Coad, SC, Goulet, GC, and McLellan, CP. Quantification of accelerometer derived impacts associated with competitive games in National Collegiate Athletic Association division I college football players. J Strength Cond Res 31(2): 330-338, 2017-The aims of the present study were to (a) examine positional impact profiles of National Collegiate Athletic Association (NCAA) division I college football players using global positioning system (GPS) and integrated accelerometry (IA) technology and (b) determine if positional differences in impact profiles during competition exist within offensive and defensive teams. Thirty-three NCAA division I Football Bowl Subdivision players were monitored using GPS and IA (GPSports) during 12 regular season games throughout the 2014 season. Individual player data sets (n = 294) were divided into offensive and defensive teams, and positional subgroups. The intensity, number, and distribution of impact forces experienced by players during competition were recorded. Positional differences were found for the distribution of impacts within offensive and defensive teams. Wide receivers sustained more very light and light to moderate (5-6.5 G force) impacts than other position groups, whereas the running backs were involved in more severe (>10 G force) impacts than all offensive position groups, with the exception of the quarterbacks (p ≤ 0.05). The defensive back and linebacker groups were subject to more very light (5.0-6.0 G force) impacts, and the defensive tackle group sustained more heavy and very heavy (7.1-10 G force) impacts than other defensive positions (p ≤ 0.05). Data from the present study provide novel quantification of positional impact profiles related to the physical demands of college football games and highlight the need for position-specific monitoring and training in the preparation for the impact loads experienced during NCAA division I football competition.

“…Human movement analysis can provide valuable information to better understand the physical demands of sporting competition [17]. This information can be used to provide feedback to athletes [6], design training programs to improve performance [3,29] and reduce injury risk [24]. The emergence of accelerometer technology has allowed quantification of movement accelerations in team sports, thereby facilitating more sophisticated analysis of the physical demands imposed on athletes [7,13,23].…”

This study assessed the validity of an accelerometer to measure impacts in team sports. 76 participants completed a team sport circuit. Accelerations were collected concurrently at 100 Hz using an accelerometer and a 36-camera motion analysis system. The largest peak accelerations per movement were compared in 2 ways: i) pooled together and filtered at 13 different cut-off frequencies (range 6-25 Hz) to identify the optimal filtering frequency, and ii) the optimal cut-off frequency split into the 7 movements performed (n=532). Raw and 25-16 Hz filtering frequencies significantly overestimated and 6 Hz underestimated motion analysis peak accelerations (P <0.007). The 12 Hz filtered accelerometer data revealed the strongest relationship with motion analysis data (accuracy - 0.01±0.27 g, effect size - 0.01, agreement - 0.55 to 0.53 g, precision 0.27 g, and relative error 5.5%; P=1.00). The accelerometer underestimated peak accelerations during tackling and jumping, and overestimated during walking, jogging, sprinting and change of direction. Lower agreement and reduced precision were associated with sprinting, jumping and tackling. The accelerometer demonstrated an acceptable level of concurrent validity compared to a motion analysis system when filtered at a cut-off frequency of 12 Hz. The results advocate the use of accelerometers to measure movements in team sport.

“…Recent technological innovations have made GPS athlete-tracking a convenient and popular method to quantify movement patterns and physical demands in sport (1,2,15,26). Global positioning system technology has been used to quantify the physiological demands of sports such as rugby league (4,5,23,39), rugby union (27,43,48), and Australian Rules (28,31). In a study on the validity and reliability of GPS in team sport movement demands, Johnston et al (29) reported that GPS seems to be a practically superior athlete-monitoring system in comparison with other methods (e.g., time-motion analysis, hand notation techniques, video-based systems).…”

Global positioning systems (GPS) technology has made athlete-tracking a convenient and accepted technique to specify movement patterns and physical demands in sport. The purpose of this study was to examine positional demands of elite youth Gaelic football match-play using portable GPS technology to examine movement patterns and heart rates across match periods. Fifty-six elite youth male Gaelic footballers (age, 15 ± 0.66 years) fitted with portable 4-Hz GPS units were observed during 6 competitive matches (60 minutes). Data provided from the GPS unit included total distance, high-intensity (≥17·km·h(-1)) distance, sprint (≥22 km·h(-1)) distance, and total number of sprints. Heart rate was monitored continuously throughout the games. Players covered a mean distance of 5732 ± 1047 m, and the mean intensity of match-play was 85% of the peak heart rate. There was a significant (p = 0.028) drop in the total distance covered in the second half (2783 ± 599 m) compared with the first half (2948 ± 580 m). In particular, there is a noticeable drop in the distance covered in the third quarter of the game (after half-time), which has implications for re-warming up at the end of the half-time interval. There was a highly significant (p < .001) difference in the distance traveled across the 5 positional groups with midfielders covering the greatest total distance (6740 ± 384 m). The significant differences found with respect to positional groups support the implementation of individual, position-specific strength and conditioning programs.
