How do you use biomechanics in your daily life, how is it used in the professional world?
In your daily life: Walking to and from class, walking up and down the stairs, working in the weight room, in our sports activities.
Professional: Physical Therapist: analyzation of gait. Coaching: analyzing technique and performance and how to adjust and improve. Occupational Therapist: analyzing and balancing out the two different sides of the body, understanding motor control and how to rebuild movement into the body. Sports Scientist: analyzing athlete techniques, analyzing the forces acting upon athletes. Chiropractor: range of motion, joint movement.
Define, give characteristics, and a gym example of a first class lever.
Definition: A simple machine where the fulcrum is between the load and the resistance.
Characteristics: Made to either magnify force or to magnify speed and distance. Position of the fulcrum depends on how much effort is needed to move the load. If the fulcrum is closer to the load, then less effort is required.
Gym Examples: Triceps extension, nodding a head for/backwards, Leg press, quad extension, pedaling a bike.
Sport example: Soccer player heading the ball.
Describe how knowledge of mechanical principles can be used to prescribe resistance training.
Knowledge of mechanical principles can be used to prescribe resistance training because if you understand levers then you can easily manipulate an exercise to make it harder for the athlete to perform. Making it harder puts the athlete at a mechanical disadvantage and helps them grow to become stronger athletes and make them better at their sport. Manipulating the grip or load changes the way the body has to apply force and can alter mechanical advantages.
