As we learn about the musculoskeletal system, I decided to try a cycling class, specifically spinning, as my new activity. I chose this workout because cycling is a popular form of aerobic exercise that emphasizes cardiovascular health while also engaging various muscle groups. Additionally, I wanted to challenge myself with a rhythmic, high-intensity workout that I had not tried extensively before. I liked the structured nature of spinning classes, the motivation provided by an instructor, and the opportunity to participate in a group activity. However, I found some aspects challenging, such as maintaining proper posture during intense intervals and managing the persistent discomfort in my quadriceps after extended periods. If I continue with this activity, my goals include increasing my endurance, enhancing leg strength, and improving overall cardiovascular fitness. I would recommend this workout to others seeking an engaging, low-impact aerobic exercise that is scalable to different fitness levels.

From an anatomical and physiological perspective, cycling primarily targets the lower body muscles, especially the quadriceps, hamstrings, gluteal muscles, calf muscles, and hip flexors. The activity involves repetitive flexion and extension of the knees and hips, engaging large muscle groups responsible for propulsion and stability. The activity is considered aerobic exercise because it involves sustained, rhythmic movement performed at moderate to vigorous intensities, which elevates heart rate and promotes cardiovascular health (American Heart Association, 2020). During spinning, the muscle fibers predominantly utilize aerobic cellular metabolism, as the activity is sustained over an extended period, requiring oxygen to generate ATP efficiently (McArdle, Katch, & Katch, 2015). However, during high-intensity intervals or sprints, anaerobic pathways may temporarily supplement aerobic metabolism, especially in fast-twitch muscle fibers. As for muscle contractions, spinning primarily involves isotonic movements—concentric contractions during the pedal stroke and eccentric contractions when resisting downward movement. Isometric contractions also occur when maintaining balance and posture on the bike, particularly during stand-up climbs or stabilization phases.

If considering a circuit training session that alternates between lifting weights and running, a specific example would involve performing resistance exercises like squats or lunges followed by a short sprint. During resistance exercises, muscles undergo concentric and eccentric isotonic contractions to control movement and generate force. During running, especially in sprinting or hill sprints, muscle fibers engage in both aerobic and anaerobic metabolism depending on the intensity and duration. Sprinting relies heavily on anaerobic glycolysis, especially in fast-twitch fibers, providing rapid energy for short bursts of high effort. The combination of strength training and cardio in circuit workouts enhances muscular endurance, strength, and cardiovascular capacity, contributing to overall musculoskeletal health (Reed et al., 2020). Personally, stepping out of my comfort zone by combining these elements challenged my muscular strength and aerobic endurance, highlighting the interconnectedness of the muscular and skeletal systems in supporting movement and stability (Enoka & Duchateau, 2008).

In conclusion, engaging in new physical activities like spinning provides not only cardiovascular benefits but also opportunity to understand the functional roles of different muscle groups. Recognizing the types of muscle contractions involved and metabolic pathways utilized enhances our understanding of how exercise impacts the musculoskeletal system. By exploring various activities that incorporate different movement patterns and intensities, we can develop well-rounded exercise routines that promote musculoskeletal health, improve performance, and prevent injuries. Incorporating credible scientific sources enriches this understanding, making exercise a scientifically grounded and effective pursuit for overall health and wellness (Caspersen, Powell, & Christenson, 1985).
