Outcome Measures

Primary Outcomes (1)

  • Decrease of the biofunctional age (BFA) through a 12 week Iyengar yoga intervention compared to the control group with no yoga classes. In order to evaluate the BFA a biofunctional Status (BFS) has to be assessed.

    The BFS is a generic, age- and sex-specific test battery comprising holistic characteristics from physical, mental-emotional and social areas. The single values of the BFS test battery were scaled and differentiated for chronological age (CA) and sex. Their summation makes up the so-called Bio-functional Age Index BFAI (BFAI = Σ (B-X/B-L)n/n). The BFAI is a relative measure compared to a reference population, out of which norm charts were developed. By definition, the reference population's BFAI is identical with its CA. A BFAI of an individual may be transformed into BFA (years) by means of gerontologic aging tables. This BFA (years) relates to the mean value of a certain CA. The BFA is based on a sex-specific regression and factor analysis of functional age (Mathieu et al., 2018. Illness perception in overweight and obesity and impact on bio-functional age. Archives of gynecology and obstetrics, 298(2), p. 417)

Study Arms (2)

Intervention

EXPERIMENTAL

The intervention group receives weekly 90 minute yoga classes over a course of 12 weeks. They are also asked to do two 45-minute yoga classes at home each week and document these in a Diary.

Behavioral: Iyengar Yoga

Control

NO INTERVENTION

The control group receives an assessment of their biofunctional status at the beginning and the end of the study (same as the intervention group).

Interventions

Iyengar YogaBEHAVIORAL

Weekly 90 minute Iyengar Yoga classes taught y a professional instructor. Twice weekly 45 minute self practice of Iyengar Yoga at home by the participants
