This study surveyed national, elite and world class athletes (<i>n</i> = 147) competing in the female category regarding their opinions on the eligibility of DSD athletes in elite sport. The study compared current and retired Olympic sport athletes, elite versus world class athletes and current Olympic sport versus current Olympic-recognised sport athletes. Most athletes believed that it was an unethical requirement to medicate in order to comply with eligibility regulations (67.2%). Overall, athletes did not support a separate category for DSD athletes, an opinion most strongly held for precision sports (69.5%) and a majority believed their participation in the female category was fair (54.4%, precision sports). This opinion was more commonly held by Olympic-recognised sport than current Olympic sport athletes, particularly for sports heavily reliant on physical capacity (61.1% vs. 20%). More current Olympic sport athletes believed that the eligibility of DSD athletes for the female category was unfair, compared to Olympic-recognised sport athletes. Athletes agreed that sports federations could be doing more to make sport more inclusive for DSD athletes (82.2%), with only 8.2% believing such athletes were treated fairly.

Data were drawn from a population-based nationwide cross-sectional study, involving 2886 male and 3034 female participants aged 14–64 who were part of the German Health Interview and Examination Survey (2008–2011) and the Examination Survey for Children and Adolescents (2014–2017).

Multivariable survey-weighted mixed linear regression analyses were conducted to assess the associations of potential correlates with pLT₂. Among both sexes, being involved in physical exercise (PE) and activity (PA) and having a tertiary education was associated with hana higher pLT₂, whereas currently smoking and classified as overweight or obese was associated with a lower pLT₂. Among females being single and among males, a higher fruit consumption was associated with a higher pLT₂. A lower pLT₂ was associated with a higher waist circumference and a high junk food intake in females and being a former smoker and being single in males. Overall, PE and nonsmoking are the most important determinants for pLT₂; therefore, policies and interventions targeting those factors would be important for preventing noncommunicable diseases.

Although exponential modeling provides practical insights into recovery dynamics, the inability to incorporate an individual's pre-exercise baseline oxygen consumption value (V̇O₂__baseline) can lead to inaccurate interpretations. A user-defined baseline allows for more precise modeling by aligning recovery kinetics with the true physiological endpoint, representing the individual's actual recovery target after a sufficient rest. To overcome this limitation, this study employs a customized Python algorithm that incorporates user-defined baseline V̇O₂ and uses both mono-exponential and bi-exponential models, aiming to improve upon existing analytical methods. Twenty-two male amateur soccer players participated in this study and performed a 30-s Wingate test. V̇O₂ was measured continuously before, during, and after exercise via a metabolic gas analyzer. Both mono-exponential and bi-exponential models were used to analyze post-exercise V̇O₂ kinetics.
