V̇Opeak estimation in people with overweight and obesity before and after a 14-week lifestyle intervention.

Purpose: This study aimed to investigate the validity and applicability of a non-exercise estimation of cardiorespiratory fitness using resting seismocardiography (SCG eV̇Opeak) in people with overweight and obesity before and after a 14-week lifestyle intervention.

Methods: The study was carried out at a Folk high school that offers 14-week courses on lifestyle changes where participants live at the school and voluntarily participate in daily lectures and activities. Sixty-seven men and women with age and body mass index between 18 and 70 years and 25-50 kg·m were tested at baseline, and 52 had a follow-up test after 14 weeks.

Accuracy of a non-exercise method using seismocardiography for the estimation of V̇Opeak in sub-elite football players.

A non-exercise method equation using seismocardiography for estimating V̇Opeak (SCG V̇Opeak) has previously been validated in healthy subjects. However, the performance of the SCG V̇Opeak within a trained population is unknown, and the ability of the model to detect changes over time is not well elucidated. Forty-seven sub-elite football players were tested at the start of pre-season (SPS) and 36 players completed a test after eight weeks at the end of the pre-season (EPS).

Peak fat oxidation, peak oxygen uptake, and running performance increase during pre-season in sub-elite male football players.

Purpose: In Football, the high-intensity running bouts during matches are considered decisive. Interestingly, recent studies showed that peak fat oxidation rates (PFO) are higher in football players than other athletes. This study aimed to investigate whether PFO increases following a pre-season.
