Muscle contractions are fundamentally influenced by oxygen. Whether you're a professional athlete or just someone who likes to stay active, knowing how oxygen affects muscle function will help you perform better in sports. In this blog, we'll look into how muscle oxygen sensors like the PLUS and FYER revolutionize your peak performance and examine the critical role that oxygen plays in muscle contraction.

While cycling is captivating to watch, it's also accessible for everyone to enjoy and improve their well-being. Serious cyclists target specific races, preparing with intense training and recovery plans. Monitoring progress helps set achievable goals and break personal records. Using muscle oxygen, a case study reveals that a 6-week high-intensity interval training (HIIT) program can improve aerobic fitness. By observing changes in muscle oxygen levels during exercise, we can measure better oxygen utilization and improved overall performance.

In this episode, hosts Kim and Jeroen discuss Near InfraRed Spectroscopy (NIRS) and its application in sports and fitness. They explain that NIRS sensors, like the FYER from Train.Red, can measure oxygen levels in muscles, allowing individuals to understand their body's responses during exercise.The hosts mention that NIRS can provide insights into muscle recovery and performance optimization, highlighting the significance of the recovery graph in assessing muscle training effectiveness. 
In this episode of the BE AHEAD podcast by Train.Red, the hosts Kim and Jeroen discuss Near InfraRed Spectroscopy (NIRS). NIRS is a way of measuring the oxygenation or de-oxygenation of tissue, specifically muscle, using light. It provides insights into muscle physiology and performance. NIRS is more powerful than pulse oximetry (SpO2) as it can penetrate deeper into the muscle. It helps in assessing muscle activation, efficiency, and recovery during exercise. NIRS measures the saturation of hemoglobin with or without oxygen and can be used to identify muscle imbalances. While NIRS doesn't directly indicate health, it provides information about an individual's fitness level and their ability to recover from exercise.
Train.Red utilizes infrared light in the near-infrared region to measure changes in oxygenation levels in the muscle tissue. By distinguishing between oxyhemoglobin and deoxyhemoglobin based on their absorption behavior, Train.Red quantifies the changes in concentration. The technology provides direct feedback on various training parameters, such as optimal pacing, recovery times, and muscle exhaustion, accessible through smartphones, sport watches, or the Train.Red application.
The body uses multiple biochemical systems to produce ATP (muscle fuel) during exercise, with one system requiring oxygen. The distribution and consumption of oxygen play a crucial role in performance, as indicated by the 'Fick Equation' that relates oxygen consumption to cardiac output and oxygen content of arterial and venous blood.
