Abstract
Objective.
The study is aiming to demonstrate the role of proper testing and
adaptation of training in order to increase physical performance and
decrease the risk of injury. Material and Methods.
22 rugby players underwent measurements of explosive force using
Myotest system and one leg explosive force using Optojump system,
before the start of a training camp and after two months of training.
Training comprised: strength training (once on 48 hours, 3-6 sets of
4-6 repetitions at 80-95% 1RM), aerobic training, and field training.
The training program considered the power differences between legs and
emphasized the strengthening of the weaker leg. Results.
At the end of the study we observed a significant increase in explosive
power of the lower limbs (from 39.41 ±6.998 W/kg to
46.36±8.399 W/kg, p=0.009), and also of explosive force at
the same level (from 21.59 N/kg ±1.82 to 25.75
±3.25 N/kg (p=< 0.001). Regarding the
differences in explosive power between legs, we noticed a mean
difference of 0.48 W/kg between right and left leg. After only 2 months
of training the mean differences was reduced to 0.28 W/kg. Conclusions.
Emphasizing the strength training of the weaker leg, we can adjust the
muscles imbalance and decrease the risk of sport injury. Two months of
proper exercise training, can significantly increase explosive power
and force of the lower limbs. Based on testing results, physical
trainers should adjust muscular imbalance of athletes and also conceive
proper rehabilitation in case of important asymmetry after a sport
injury.
