Background: Physical inactivity, overweight, and work-related stress are major concerns today. Psychological stress causes physiological responses such as reduced heart rate variability (HRV), owing to attenuated parasympathetic and/or increased sympathetic activity in cardiac autonomic control. This study's purpose was to investigate the relationships between physical activity (PA), body mass index (BMI), and HRV-based stress and recovery on workdays, among Finnish employees.

- - This study examined how physical activity (PA) relates to stress and recovery, using heart rate variability (HRV) as an objective measure along with subjective stress assessments over time.
- - Participants included 221 working-age individuals who were overweight and experiencing psychological distress, and data was collected at three different points: baseline, 10 weeks, and 36 weeks after an intervention.
- - Findings indicated that higher initial levels of PA and lower objective stress and better recovery were linked to reductions in subjective stress across the long term, even after factoring in the intervention group effects.
The effects of endurance training on endurance performance characteristics and cardiac autonomic modulation during night sleep were investigated during two 4-week training periods. After the first 4-week training period (3 x 40 min per week, at 75% of HRR) the subjects were divided into HIGH group (n = 7), who performed three high-intensity endurance training sessions per week; and CONTROL group (n = 8) who did not change their training. An incremental treadmill test was performed before and after the two 4-week training periods.

Another aim was to investigate how physical activity (PA), body composition, and age are associated with subjective stress, objective stress, and recovery.
Methods: Working-age participants (n = 221; 185 women, 36 men) in this cross-sectional study were overweight (body mass index, 25.
