Time-specific Exercise in Circadian Context

The project aims to explore the mechanisms, by which physical activity can support healthy ageing and decrease the negative impact of ageing on the circadian system, musculoskeletal system and immunity.

About this study

The main aim of the project is to examine the effect of as well as of the three-month, timely specific training intervention on the functionality of circadian organization in elderly volunteers. The additive aim is to examine the effect of lifelong endurance physical activity, along with the experimental training intervention on the body composition, bone density, and selected hormonal, biochemical, histological and molecular indicators of metabolic health.

Partial aims are as follows:n to explore the effect of morning and afternoon training on the most significant parameters, identified by the previous cross-sectional study, in sedentary elderly. Furthermore, to clarify adaptation mechanisms of experimental training protocol on selected parameters, that may explain possible differences in mechanisms of active and passive aging.

Who can participate

Healthy volunteers accepted: Yes

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • no history of regular physical activity training and exercise of more than 150 minutes of moderate or 75 minutes of higher intensity per week.
  • Body mass index (BMI) between 18.5 and 30 kg/m2 for all groups

Exclusion criteria

for probands will be:

  • Recent or current infection, physical disability,
  • malignant, cardiovascular, metabolic, autoimmune diseases,
  • Malnutrition and pharmacological interference (e.g., steroids, non-steroidal anti-inflammatory agents, immunosuppressive and antineoplastic drugs).

Use of performance enhancing drugs in the past and during the study period will condition exclusion.

Treatment and study plan

Combined training

Procedure

12-week long time specific combined training 2 times a week

Primary outcomes

  1. Bone mineral density

    Time frame: 12 weeks

    The proportion of total body fat mass, visceral fat mass, total body mass and bone density will be measured using Dual-energy X-ray Absorptiometry (DXA, hologic fan-beam bone densitometer Discovery QDR series). The DXA testing procedure will follow Kralik et al. (2019). All DXA procedures will be performed by a board-certified radiologist.
