Introduction
NCAA Division I soccer matches are played with 11 players per side, and the average NCAA Division I soccer team roster contains 27 players.1 Substitutions are dictated by match play, tactical
considerations, injury, and player fatigue. In addition, coaches may take physical capabilities and performance on various sport specific fitness tests into consideration when selecting a starting lineup for
competitions.
Unlike international play, the number of substitutions allowed per game under NCAA rules is unlimited, given that a player does not re-enter the field of play in the same half after she is removed.1 This could
contribute to an increase in the number of substitutions per matches and necessitate both starting and non-starting players to be able to maintain a high level of play during matches.
The purpose of this study was to determine if there are differences in physiological characteristics across projected starting and non-starting players in a Division I collegiate female soccer team.
Practical Applications
Soccer coaches and sports performances coaches should ensure that an adequate level of physical fitness is achieved and
maintained by all members of a Division I collegiate female soccer team, regardless of projected playing time.
Soccer coaches and sports performance coaches should also take care to monitor fitness levels of all players on the roster
throughout the competitive season to ensure that non-starting players and players who may accumulate less minutes of play
during matches and training participate in additional fitness training if necessary.
Methods
 25 female soccer players from the same Division I squad were recruited. The team’s coaching staff determined 11 players projected
to start during the following season, and 14 players projected to be non-starters.
 The players completed various field tests during the non-traditional season, including assessments of: linear speed (0-5, 0-10, 0-30
meter [m] sprint intervals), COD speed (Arrowhead; pro-agility shuttle; 54.86-m [60-yard] shuttle; Figure 1); vertical and standing
broad jump (SBJ); and soccer-specific fitness (Yo-Yo Intermittent Recovery Test Level 1 [YYIRT1]).
 A one-way analysis of variance (p < 0.05), with Bonferroni post hoc, derived any differences for projected starting and non-starting
players. Although data from goalkeepers was collected, they were not included in the statistical analysis. Effect sizes (d) were also
calculated for selected comparisons.
Results
There were no significant differences (p > 0.05) in physiological characteristics between starting and
non-starting players for this squad (Table 1).
Most effects were low (0.01 < d < 0.45).
Although non significant (p = 0.06), there was a moderate effect for the 30-m sprint time for starting
and non-starting players (d = 0.63), as projected starting players had a 2% faster sprint time
compared to non-starting players.
Conclusions
 Division I collegiate female soccer players from the same playing squad demonstrated similar physical characteristics between projected
starting and non-starting players. This could be due to the fact that most players undergo very similar training loads during the non-
traditional season.3
 Relatively equivalent levels of fitness among all starting and non-starting players within a squad could increase the likelihood of
maintaining a high level of play across various player lineups and allow coaches greater flexibility in player substitutions (notwithstanding
player skill levels).
 Similar to established research,4 projected starting players tended to exhibit better speed over 30 m, which could suggest that more
skilled players may have a greater ability to maintain top speed over longer distances.

Introduction NCAA Division I soccer matches are played with 11 players per side, and the average NCAA Division I soccer team roster contains 27 players.1 Substitutions are dictated by match play, tactical considerations, injury, and player fatigue. In addition, coaches may take physical capabilities and performance on various sport specific fitness tests into consideration when selecting a starting lineup for competitions. Unlike international play, the number of substitutions allowed per game under NCAA rules is unlimited, given that a player does not re-enter the field of play in the same half after she is removed.1 This could contribute to an increase in the number of substitutions per matches and necessitate both starting and non-starting players to be able to maintain a high level of play during matches. The purpose of this study was to determine if there are differences in physiological characteristics across projected starting and non-starting players in a Division I collegiate female soccer team. Practical Applications Soccer coaches and sports performances coaches should ensure that an adequate level of physical fitness is achieved and maintained by all members of a Division I collegiate female soccer team, regardless of projected playing time. Soccer coaches and sports performance coaches should also take care to monitor fitness levels of all players on the roster throughout the competitive season to ensure that non-starting players and players who may accumulate less minutes of play during matches and training participate in additional fitness training if necessary. Methods  25 female soccer players from the same Division I squad were recruited. The team’s coaching staff determined 11 players projected to start during the following season, and 14 players projected to be non-starters.  The players completed various field tests during the non-traditional season, including assessments of: linear speed (0-5, 0-10, 0-30 meter [m] sprint intervals), COD speed (Arrowhead; pro-agility shuttle; 54.86-m [60-yard] shuttle; Figure 1); vertical and standing broad jump (SBJ); and soccer-specific fitness (Yo-Yo Intermittent Recovery Test Level 1 [YYIRT1]).  A one-way analysis of variance (p < 0.05), with Bonferroni post hoc, derived any differences for projected starting and non-starting players. Although data from goalkeepers was collected, they were not included in the statistical analysis. Effect sizes (d) were also calculated for selected comparisons. Results There were no significant differences (p > 0.05) in physiological characteristics between starting and non-starting players for this squad (Table 1). Most effects were low (0.01 < d < 0.45). Although non significant (p = 0.06), there was a moderate effect for the 30-m sprint time for starting and non-starting players (d = 0.63), as projected starting players had a 2% faster sprint time compared to non-starting players. Conclusions  Division I collegiate female soccer players from the same playing squad demonstrated similar physical characteristics between projected starting and non-starting players. This could be due to the fact that most players undergo very similar training loads during the non- traditional season.3  Relatively equivalent levels of fitness among all starting and non-starting players within a squad could increase the likelihood of maintaining a high level of play across various player lineups and allow coaches greater flexibility in player substitutions (notwithstanding player skill levels).  Similar to established research,4 projected starting players tended to exhibit better speed over 30 m, which could suggest that more skilled players may have a greater ability to maintain top speed over longer distances.
