English abstract
This study aimed to examine the effect of lateral balance exercises on
muscular ability for lower extremities using drop jump (DJ) and examine the impact
of lateral balance exercises on sprint performance using (the 20) m test and (Agility
T-test). The study sample consisted of 24 female bachelor students recruited from
the Department of Physical Education and Sport Sciences at Sultan Qaboos
University for the academic year 2023/2024, (Age = 20.6 ± 0.7 years), (Height =
157.5 ± 6.1 cm), (Weight = 52.4 ± 8.3 Kg), (BMI = 21.1 ± 2.8 Kg/ m2
). All study
subjects performed drop jump (DJ), (20) m sprint, and (Agility T-test) followed by
side balance exercises protocol for both legs (right and left) using the balance tool
(BOSU). The first position is without balance exercises; the second is three sets and
five repetitions with a 90-second rest between sets. Results showed that there was
no effect of balance exercises on the performance of DJ (P= 0.85) and (20) m sprint
(P= 0.49). On the other hand, there were significant differences in RSI which is an
indicator of DJ (P=0.02). In addition, there was a significant difference in (the
Agility T-test) (P= 0.00). In conclusion, the lateral dynamic balance exercises
improve the reactive strength index (RSI) and the sprint performance time with a
change of direction (Agility T-test).
