BACKGROUND: Lower levels of physical activity and cardiorespiratory fitness are key risk factors of chronic adult diseases. Physical activity and cardiorespiratory fitness are predicted by birth weight, but the underlying parental and pregnancy-related factors remain largely unknown. We examined how prenatal determinants are associated with physical activity and cardiorespiratory fitness in adolescence. METHODS: Of the 16-year-old members of the population-based Northern Finland Birth Cohort 1986 (NFBC 1986), 6682 singletons with no major physical disability reported their amount of physical activity outside school hours, and 4706 completed a submaximal cycle ergometer test assessing cardiorespiratory fitness...

OBJECTIVES: Dicarbonyl stress and high concentrations of advanced glycation endproducts (AGEs) relate to an elevated risk for cardiovascular diseases (CVD). Exercise training lowers the risk for future CVD. We tested the hypothesis that lifelong endurance athletes have lower dicarbonyl stress and AGEs compared to sedentary controls and that these differences relate to a better cardiovascular health profile. DESIGN: Cross-sectional study. METHODS: We included 18 lifelong endurance athletes (ATH, 61±7years) and 18 sedentary controls (SED, 58±7years) and measured circulating glyoxal (GO), methylglyoxal (MGO) and 3-deoxyglucosone (3DG) as markers of dicarbonyl stress...

BACKGROUND: Depression and metabolic syndrome (MetS) are frequently comorbid disorders that are independently associated with premature mortality. Conversely, cardiorespiratory fitness (CRF) is associated with reduced mortality risk. These factors may interact to impact mortality; however, their effects have not been assessed concurrently. This analysis assessed the mortality risk of comorbid depression/MetS and the effect of CRF on mortality in those with depression/MetS. METHODS: Prospective study of 47 702 adults in the Cooper Center Longitudinal Study...

BACKGROUND: Cardiorespiratory fitness assessment and training among manual wheelchair (MW) users are predominantly done with an arm-crank ergometer. However, arm-crank ergometer biomechanics differ substantially from MW propulsion biomechanics. This study aimed to quantify cardiorespiratory responses resulting from speed and slope increments during MW propulsion on a motorized treadmill and to calculate a predictive equation based on speed and slope for estimating peak oxygen uptake (VO2peak) in MW users...

Both severe obesity and type 2 diabetes (T2DM) are associated with reduced pulmonary function and reduced cardiorespiratory fitness. We investigated whether T2DM further aggravates the impaired pulmonary function and cardiorespiratory fitness in subjects with severe obesity. In this cross-sectional study pulmonary function (forced expiratory volume within 1 s, FEV1; vital capacity, VC) was assessed in 65 severely obese subjects with T2DM (T2DM group) and 65 severely obese subjects without T2DM (non-T2DM group), pairwise matched for sex, age, weight, and height...

OBJECTIVES: This study evaluated the contributions of obesity and changes in body mass index (BMI) in mid-life to long-term heart failure (HF) risk independent of cardiorespiratory fitness (CRF) levels. BACKGROUND: Obesity and low CRF are well-established risk factors for HF. However, given the inverse association between CRF and obesity, the independent contributions of BMI toward HF risk are not fully understood. METHODS: We included 19,485 participants from the Cooper Center Longitudinal Study who survived to receive Medicare coverage, from 1999 to 2009...
