Nicotinamide adenine dinucleotide, a coenzyme critical for cellular energy metabolism that declines with age. NAD+ precursors like NMN and NR are studied as longevity interventions.

Mechanistic target of rapamycin, a key nutrient-sensing pathway that regulates cell growth and aging. Inhibiting mTOR (e.g., with rapamycin) has shown lifespan extension in multiple organisms.

A class of drugs that selectively eliminate senescent (aged, dysfunctional) cells to reduce inflammation and improve tissue function.

What is Epigenetic clock?

A biomarker based on DNA methylation patterns that estimates biological age, often more predictive of health outcomes than chronological age.

The period of life spent in good health, free from chronic diseases and disability associated with aging.

An immunosuppressant drug that inhibits the mTOR pathway. Research shows rapamycin may extend lifespan and improve age-related health outcomes in multiple species.

What is Biological age?

A measure of how well or poorly your body is functioning relative to your chronological age, assessed through biomarkers such as DNA methylation, telomere length, and blood panels.

What is Caloric restriction?

A dietary regimen that reduces calorie intake without malnutrition. Caloric restriction is one of the most studied interventions shown to extend lifespan across species.

Protective caps at the ends of chromosomes that shorten with each cell division. Telomere length is associated with aging and age-related diseases.

A state in which cells permanently stop dividing but resist death, accumulating with age and secreting inflammatory factors that damage surrounding tissue.

A second-generation epigenetic clock that predicts time to death and is considered one of the most accurate measures of biological aging.

What is Inflammaging?

Chronic, low-grade inflammation that increases with age and contributes to the development of age-related diseases including cardiovascular disease, diabetes, and neurodegeneration.

The large-scale study of proteins in biological systems. In longevity research, proteomics identifies blood protein signatures that predict biological age and disease risk.

What is Yamanaka factors?

A set of four transcription factors (Oct4, Sox2, Klf4, c-Myc) that can reprogram adult cells to a pluripotent state. Partial reprogramming with Yamanaka factors is being explored to reverse cellular aging.

Nicotinamide mononucleotide, a precursor to NAD+ that is widely studied as a supplement to boost cellular energy and combat age-related decline.

A gene-editing technology that allows precise modifications to DNA. In longevity research, CRISPR is used to study and potentially modify genes associated with aging.

Life Time brings VO₂ max and metabolic testing to the masses

Life Time’s recent nationwide rollout of SpiroFit metabolic testing technology marks a significant advancement in making lab-grade VO₂ max and metabolic insights accessible to the general public. Traditionally confined to elite athletic settings, this technology enables everyday fitness enthusiasts to gain valuable insights into their metabolic processes during exercise. By measuring how the body utilizes oxygen and fuel, SpiroFit allows users to identify key metabolic transitions, such as the shift from fat to carbohydrate burning, thus providing actionable data to optimize training.

The implications of this technology extend beyond mere fitness tracking. VO₂ max is increasingly recognized as a critical indicator of overall cardiovascular health and long-term wellness, with higher levels correlated to improved resilience against chronic diseases and an extended healthspan. Life Time’s integration of SpiroFit into its clubs is a strategic move that aligns with the growing recognition of metabolic health as a foundational aspect of aging research. By delivering clinical-level insights in a user-friendly format, SpiroFit empowers individuals to train smarter and achieve measurable progress, enhancing their understanding of personal health metrics.

The broader impact of SpiroFit lies in its potential to shift research paradigms within the longevity field. By democratizing access to metabolic data, Life Time is not only fostering a culture of informed fitness but also paving the way for future innovations in health monitoring. As consumers demand more personalized and data-driven health insights, tools like SpiroFit may catalyze a shift in how we approach aging and healthspan research, emphasizing the importance of metabolic efficiency and its role in promoting longevity.
