Answer:
Lucas can apply the sport principles to get in competition shapre for the race by: 1.- He can focus on progression, increasing the intensity and time he spends on the paddleboard.
Explanation:
To understand this answer we need to remember the principle of sport and analyze each answer.
The second options say he can continue paddleboarding three times per week to avoid reversibility. But reversibility is a state in which the subject loses its performance ability. In our case is incorrect because Lucas wants to get better shape not prevent the loss of his shape so it's wrong.
The third option says that he can lift weights and run a few days a week to add specificity to his training. However, in our scenario of a paddleboarding competition lifting weight and running is not specificity training. So it is wrong.
The fourth Option says he should explore other types of physical activity so paddleboarding doesn't become tedious. Nevertheless, the objective here is to improve shape in paddleboarding and stop doing it will do the opposite.
So, the first option is right.
