38. Arnold vs the Blade Runner: The anatomy of bulking up with weights vs running

Research

Cardio or weight training? That is one of the most common and basic questions one will find themselves asking when signing up for a gym. Cardio such as running or swimming will help you achieve a more toned look. Weightlifting with a constant progression overload will help you bulk up. When one wishes to tone up, they try to reduce their body fat to tighten the muscle and give it shape. To bulk up is to try and accumulate as much muscle mass as you can. There is no right or wrong answer to which one is “better.” It all comes down to what fitness goal YOU are trying to reach. With that being said, the two are as different as night and day.

Cardio – Cardio is short for cardiovascular conditioning. It’s an aerobic exercise that relies on oxygen to get your breathing and heart rate up. Getting your heart rate up is essential to promote blood flow through your body. This whole process will allow you to burn many calories, which is why it’s the way to go if your goal is weight loss. In addition to weight loss benefits, cardio is terrific for your overall health. Keeping your heart pumping like this will allow your heart and lungs to move oxygen through your body efficiently.

Weight lifting – this is an anaerobic exercise. It does not rely on oxygen in the way cardio does. Instead, the activities performed here to break down glucose for energy. Weight lifting produces stress on your muscles which causes micro-tears in them. These micro-tears are where you will begin to bulk if followed by the appropriate diet. After a rigorous training session of weight lifting, one must eat a lot of protein, at least 0.8 grams per kilogram of body weight. This will help feed those muscle tears with protein which is essentially the building blocks of muscle. Another critical component of this diet is making sure you eat your carbs. As mentioned, weight lifting breaks down glucose for energy which can be replenished with healthy complex carbs. The benefits of weight training will have you burning calories all day and help to prevent any future injuries.

Critical thinking

As an avid gym-goer myself, my favorite thing to do is resistance weight training. So I’ll go to the gym and lift weights, do squats, bench press, etc. However, a mixture of both cardio and weights is the most ideal. You’ll have the best of both worlds! Both do wonders for your health. So to conclude, cardio will burn more calories during your workout and burn fat faster. Weight training will help you burn calories all day and help you accumulate muscle mass.

6. Antagonists, Prime movers, and Synergists

Research:

The human body is composed of muscles that work together to support the motion and tasks we perform. One of these muscle functions includes the upper arm and forearm. It consists of three bases, the prime mover, synergist, and antagonist. The prime mover also called an agonist, is mainly responsible for the human arm’s movement. It assembles the most power throughout a joint operation and includes the muscle, biceps brachii, which functions as a flexor (Saladin et al., 2021, p. 305).

The synergist plays a role in this action by assisting the prime mover. It proceeds as a double force for the flexor due to its muscle, brachialis. The biceps brachii extends over the brachialis and work together to help bend the elbow (Saladin et al., 2021, p. 305). Both of these muscles are connected but are not very alike. For example, the synergist secures the joint with the aim that the prime mover does its role of performing a gesture (Saladin et al., 2021, p. 305).

The antagonist is the complete flip-side of a prime mover function. An antagonist is a muscle relaxer that attentionally reduces the speed of a movement without taking absolute control over the prime mover. The purpose is to help human beings grasp various objects into their hands without receiving a fracture (Saladin et al., 2021, p. 305). While the elbow flexes, the prime mover becomes the brachialis, and the antagonist takes the form of the triceps (Saladin et al., 2021, p. 305). Each of these plays a role in supporting our activities.

Critical Thinking:

After researching the functions of antagonists, prime movers, and synergists, I’ve gained a lot of knowledge of what each muscle does in those areas to make sure we sustain a balance in both movement and pace. For example, if I decide to go out and jump rope. These functions would begin to apply by allowing me to lift the rope without too much stamina in the arm and place it in my hands. Then I could start rotating the jump rope while jumping as my upper arms move forward to make sure I do not swing out of control.
