This study aimed to investigate the impact of swim training intensity and duration on cardiac structure and function in mildly hypertensive women. Sixty-two mildly hypertensive women were randomized to 15 weeks of either (1) high-intensity swimming (HIS, n = 21), (2) moderate-intensity swimming (MOD, n = 21) or (3) control (CON, n = 20). Training sessions occurred three times per week.

Purpose: In 2019, an initiative to reduce sickness absence in public sector workplaces in Denmark was introduced. The initiative involved appointing a sickness absence coordinator (SA coordinator) to oversee the implementation of workplace-based sickness absence interventions. Since the role of the SA coordinator is a novel concept introduced as part of the initiative, this study investigates the responsibilities of SA coordinators and the challenges they experienced in fulfilling this role during the implementation process.

Article Synopsis
  • Strenuous exercise can trigger cardiac events like myocardial infarction and sudden death, especially in patients with stable coronary artery disease (CAD).
  • In a study with 164 CAD patients and 25 healthy individuals, platelet aggregation and thrombin generation were measured before, after, and 2 hours post-exercise using various assays.
  • Results showed an initial increase in platelet aggregation and thrombin fragments immediately after exercise in both groups, but by 2 hours post-exercise, CAD patients demonstrated increased fibrinolysis, while healthy individuals' measures returned to baseline.

Background And Purpose: Hamstring strength testing is crucial in assessing this important muscle group during rehabilitation and injury prevention. The purpose of this study was to evaluate the reliability and validity of measuring strength in a maximally lengthened position using a handheld dynamometer (HHD) compared to isokinetic testing.

Methods: Twenty healthy and active participants were recruited, and isometric strength testing was performed both on the Biodex machine and isometric end-range hamstring testing with the HHD on two occasions.
