• Multidimensional physical activity profiles and changes in physical function and self-reported walking ability among community-dwelling older adults : a 4-year follow-up 

  Palmberg, Lotta; Karavirta, Laura; Löppönen, Antti; Hyvärinen, Matti; Rantanen, Taina; Rantalainen, Timo (Oxford University Press (OUP), 2023)

  Purpose Physical activity (PA) is multidimensional but often assessed using single metrics. We studied how data-driven PA profiles predict changes in physical functioning and self-reported walking ability over time among ...

• Neighborhood Mobility and Unmet Physical Activity Need in Old Age : A 2-Year Follow-Up 

  Palmberg, Lotta; Portegijs, Erja; Rantanen, Taina; Aartolahti, Eeva; Viljanen, Anne; Hirvensalo, Mirja; Rantakokko, Merja (Human Kinetics, Inc., 2020)

  Background: Many older people report a willingness to increase outdoor physical activity (PA), but no opportunities for it, a situation termed as unmet PA need. The authors studied whether lower neighborhood mobility and ...

• Reciprocal Associations Between Relative or Absolute Physical Activity, Walking Performance, and Autonomy in Outdoor Mobility Among Older Adults : A 4-Year Follow-Up 

  Lindeman, Katja; Koivunen, Kaisa; Rantalainen, Timo; Rantakokko, Merja; Portegijs, Erja; Rantanen, Taina; Karavirta, Laura (SAGE Publications, 2024)

  Objectives: To examine the reciprocal associations between walking performance, physical activity (PA), and perceived autonomy in outdoor mobility in 322 older adults. Methods: At baseline and four years later, a 6-min ...

• Free-living sit-to-stand kinematics as an indicator of lower extremity physical function 

  Löppönen, Antti (Jyväskylän yliopisto, 2023)

  Strength-demanding daily activities such as sit-to-stand (STS) transitions are essential for independent living among older adults. Measurement of STS transitions using advanced wearables offers a broader picture of physical ...

• Does telomere length predict decline in physical functioning in older twin sisters during an 11-year follow-up? 

  Sillanpää, Elina; Törmäkangas, Timo; Rantanen, Taina; Kaprio, Jaakko; Sipilä, Sarianna (Springer Netherlands; American Aging Association, 2016)

  Background: Leucocyte telomere length (LTL) is known to be associated with mortality, but its association with age-related decline in physical functioning and the development of disability is less clear. This study ...
