Strength vs Size: Know the Difference Introduction When it comes to training for strength and size, there are a lot of misconceptions and confusion about what each one actually is. Some people think that strength and size are the same thing, while others think that you can only achieve one or the other. The reality is that both strength and size are important, and they can be developed independently or together. In this article, we will unpack the differences between strength and size and explain how you can train for each one. We will also provide examples of what type of training program will help you achieve your specific goals. What Is Strength and What Is Size? Strength and size are two different measures of muscular development. Strength is the ability to generate force against an external resistance, while size is the relative measure of muscle mass. Strength is important for everyday activities, such as carrying groceries or lifting a suitcase, while size is important for esthetic appearance and performance in athletics. There are many ways to train for strength and size, but the best approach depends on the individual’s goals and training history. The Science Behind Strength and Size Strength and size are two of the most coveted physical qualities a person can possess. But what are they, and what’s the difference? Strength is the ability to generate force, while size is the accumulation of muscle mass. Size is often mistaken for strength, but it’s important to understand the two are not synonymous. A person can be big but weak, or small but strong. The determining factor between strength and size is the type of muscle fiber. Size is determined by the number of muscle fibers, while strength is determined by the ability of those fibers to generate force. Muscles are extremely important to your body, and not just because they help you look good at the pool. They do many things to keep you alive and help in daily tasks like locomotion and lifting objects. Muscle tissues are made up of cells called muscle fibers. Each muscle fiber contains many myofibrils — the parts of the muscle fiber that contract. The myofibrils line up right next to each other, giving muscles a striped, or striated, appearance. Myofibrils contract because of the sliding action of two filamentous cytoskeletal proteins, called actin and myosin: Actin filaments, or thin filaments, consist of two strands of actin wound around each other. Myosin filaments, or thick filaments, contain groups of myosin. Myosin filaments have bulbous ends called myosin heads; in muscle, multiple strands of myosin arrange with their heads pointed in opposite directions so that both ends of thick filaments look bulbous. Thin and thick filaments are organized into repeating units called sarcomeres. Dark lines called Z-lines mark off the boundaries of each sarcomere. Thin filaments attach to the Z-lines at both ends of the sarcomere, while thick filaments are unattached. Each myofibril contains thousands of sarcomeres. Types of muscle fibers Skeletal muscles are made up of individual muscle fibers. And like muscles themselves, not all muscle fibers are the same. There are two types of skeletal muscle fibers, fast-twitch, and slow-twitch, and they each have different functions that are important to understand when it comes to movement and exercise programming. So What Does Hypertrophy AKA SIZE Mean? Hypertrophy is termed as the enlargement of an organ or tissue from the increase in the size of its cells, in this case, the muscle as we are talking about muscle hypertrophy. Muscle hypertrophy refers to an increase in muscle mass. This usually manifests as an increase in muscle size and strength. There are two distinct types of hypertrophies: Myofibrillar Hypertrophy- Each fiber of the muscle cell increases in size. Relatively heavier loads with lower reps cause the most optimal myofibrillar hypertrophy. Sarcoplasmic Hypertrophy- Fibre does not increase in size, but its ability to store glycolytic enzymes and fluids increases. Relatively lighter loads with higher reps cause the most optimal sarcoplasmic hypertrophy. Although these are termed different, their relation to one another is ambiguous. WHAT CAUSES HYPERTROPHY? MECHANICAL TENSION Mechanical tension is created by using a heavy load and performing exercises through a full range of motion for a while. The time the muscle spends under tension provided by the external load (barbell, dumbbell, etc) creates mechanical tension in the muscle. When you lift weights through a full range of motion, the muscles are placed under a combination of passive and active tension since they are stretched while being activated. Why is mechanical tension such a strong driver of hypertrophy? Think of the environment we live in, what’s a constant force/stressor we have to deal with? Gravity. Over time, our bodies have adapted and evolved to better handle the constant force of gravity. That’s why we have such well-developed musculoskeletal systems. Our bodies are very good at responding to mechanical loads. We have several sensors that are responsible for detecting loads and forces and these sensors can generate growth signals as a response to constantly increased loads like a training program would produce. Mechanical tension is the most important factor in training-induced muscle hypertrophy. Mechanosensory receptors (Pacinian corpuscles, Meissner’s corpuscles) are sensitive to both the magnitude and the duration of loading, and these stimuli can directly mediate intracellular signaling to bring about hypertrophic adaptations. There are two main ways to induce large amounts of mechanical tension and subsequent growth. The first is to lift heavier weights. Studies show that subjects training in the 60-90% 1RM range had much a higher protein synthesis response to training than subjects who used lighter loads. The second way is to lift lighter weights to failure – studies show that lifting lighter weights to failure is just as effective at inducing hypertrophy as lifting heavier weights. Use both strategies in your training to create optimal amounts of tension on the muscle and force it to respond with growth. METABOLIC STRESS Do you know when you get a ‘sick pump’ in the gym? That’s metabolic stress.
The Fascinating Science Behind Mind-Body Connection: Exploring the Power of Exercise on Mental Health Introduction In today’s fast-paced world, where stress and anxiety are prevalent, finding effective ways to support mental health is crucial. Exercise has long been touted as a remedy for physical ailments, but did you know it can also work wonders for your mental well-being? In this blog, we will dive into the fascinating science behind the mind-body connection, exploring how exercise positively impacts mental health and provides a natural boost to our overall happiness. The Mind-Body Connection: 1. Understanding The Science: Exercise not only benefits our physical health but also has a profound impact on our mental well-being. Let’s explore the scientific mechanisms behind this mind-body connection: a. Neurotransmitters and Endorphins: When we engage in physical activity, our bodies release endorphins, which are neurotransmitters responsible for reducing pain perception and enhancing mood. These feel-good chemicals create a sense of well-being and happiness, providing a natural boost to our mental state. b. Neurogenesis: Regular exercise has been found to boost neurogenesis, the production of new brain cells. Particularly in the hippocampus, a region associated with memory and learning, exercise stimulates the growth of new neurons. This process enhances cognitive function and mood regulation, contributing to improved mental health. c. Stress Reduction: Exercise triggers the release of stress-reducing hormones, such as norepinephrine and serotonin. These hormones help alleviate symptoms of anxiety and depression, promoting a sense of calm and relaxation. Regular exercise can also improve our ability to cope with stress, making us more resilient in the face of life’s challenges. 2. The Mental Health Benefits of Exercise Exercise offers a wide range of mental health benefits that can positively impact our overall well-being. Let’s explore some of these benefits: a.
