Abstract: The purpose of this investigation was to
examine the relationship between maximal squat strength and
sprinting times. Seventeen Division I-AA male football athletes
(height = 1.78 +- 0.04 m, body mass [BM] = 85.9 +- 8.8 kg,
body mass index [BMI] = 27.0 +- 2.6 kg/m2, 1 repetition
maximum [1RM] = 166.5 +- 34.1 kg, 1RM/BM = 1.94 +- 0.33)
participated in this investigation. Height, weight, and squat
strength (1RM) were assessed on day 1. Within 1 week, 5, 10,
and 40 yard sprint times were assessed. Squats were performed
to a 70 degree knee angle and values expressed relative to each
subject’s BM. Sprints were performed on a standard outdoor
track surface with timing gates placed at the previously mentioned
distances. Statistically significant (p <= 0.05) correlations
were found between squat 1RM/BM and 40 yard sprint times
(r = 20.605, p = 0.010, power = 0.747) and 10 yard sprint
times (r = 20.544, p = 0.024, power = 0.626). The correlation
approached significance between 5 yard sprint times and
1RM/BM (r = 20.4502, p = 0.0698, power = 0.4421). Subjects
were then divided into those above 1RM/BM of 2.10
and below 1RM/BM of 1.90. Subjects with a 1RM/BM above
2.10 had statistically significantly lower sprint times at 10 and
40 yards in comparison with those subjects with a 1RM/BM
ratio below 1.90. This investigation provides additional evidence
of the possible importance of maximal squat strength relative to
BM concerning sprinting capabilities in competitive athletes.
