We randomized 39 physically active, healthy participants into aerobic, resistance, and mixed (aerobic and resistance) exercise groups, and a control group. The exercise groups trained for 60 min three times/week for 6 weeks, and a submaximal cycle ergometer test was performed before and after training, and 3 weeks after detraining. Continuous blood pressure was determined before and during the test. At the submaximal test, both systolic and diastolic blood pressures decreased significantly (p < 0.05) after detraining in the exercise groups. However, between pre-training and detraining, we found significant reductions at rest only in the mixed exercise group (p < 0.05). Although all exercise had similar effects on blood pressure during submaximal exercise, the mixed aerobic and resistance exercise may be optimal for blood pressure reduction, by the addition of diverse physiological pathways.

The 6-min walk test (6 MWT) is an inexpensive and simple way to test mobility and submaximal work capacity. To evaluate the test-retest reliability and validity of the 6 MWT in adults and seniors with ID and explore factors contributing to the 6 MWT distance (6 MWD). 46 participants with mild, moderate and severe ID levels (age=41 ± 11 years) performed the 6 MWT three times (T1; T2; T3) to determine test-retest reliability. To test validity, peak oxygen uptake (VO2 peak) was measured using a treadmill protocol. To analyze factors contributing to the 6 MWD, sex, height, fat mass % and fat free mass %, ID level, isometric leg strength and relative VO2 peak were also measured. The walking distances for T1, T2 and T3 were 460.3 ± 76.9; 489.4 ± 81.2 and 491.4 ± 77.9 m, respectively. The 6 MWDs between T1-T2 and T1-T3 were significantly different (p<0.001), but T2 and T3 were not different. The intraclass correlation coefficient between T2 and T3 was 0.96 indicating high reliability. Relative VO2 peak and isometric leg strength significantly contributed to the 6 MWD (R(2)=0.55). The 6 MWT is an easy, inexpensive, reliable and valid test in adults and seniors with ID. Familiarization is necessary to obtain reliable values. Relative VO2 peak and leg strength have significant impact on the distance walked.

The purpose of the study was to determine the effect of a physical exercise program on blood pressure, lipid profile and physical fitness on 16 (9 men, 7 women; 54 ± 5 years old) prehypertensive adults, without any other chronic illness. The group followed a physical exercise program for 16 weeks, which last 1.5 hour, three times a week consisting of aerobic activities and strength training. Blood pressure, lipid profile, physical fitness and anthropometric measurements were assessed pre and post training. Wilcoxon-Cox test was used to compare within group changes. Statistically significant reductions were found in basal systolic and diastolic blood pressure by ~12/9 mmHg (p < .05) respectively; VO2 peak increased by ~8 ml/Kg/ min (p < .05); the peak power achieved during the cycle-ergometer test increased by ~51 Watts (p < .05); BMI decreased by ~2 points (p < .05); triglycerides decreased by ~21 mg/dL (p < .05); cholesterol decreased by ~19 mg/dL (p < ....

The intervention of this single-arm pre-post study involved supervised, 1-hour weekly, diet sessions and 75-minute bi-weekly PA sessions of moderate-to-high intensity. This 12-week intervention targeted overweight/obese women who had recently completed BC treatment. Pre and post CRF and QoL measurements were compared using paired t-tests. Linear regression models, including baseline participants' characteristics and weight change were used to assess the association between changes in CRF and QoL. The 37 BC survivors who completed the intervention between May 7th 2012 and July 27th 2012 showed significant increases in CRF and QoL. Peak oxygen uptake (mL/kg/min) increased from 19.0 ± 2.8 to 24.0 ± 4.1 while peak workload (watts/kg) increased from 1.3 ± 0.3 ...

The aim of this study was to assess participation and adherence of overweight and obese BC survivors to a lifestyle intervention and to demonstrate the capacity of this intervention to induce weight loss and nutritional changes. This single-arm pre-post study, which involved one-hourly weekly diet sessions delivered by a dietician and 75-min bi-weekly PA sessions of moderate-to-high intensity led by PA monitors, was offered to overweight and obese BC survivors shortly after treatment.

Because of motor disabilities, cycling is difficult for them. Little is known about VO2 economy when they perform tests over cycle ergometry. Purpose: We investigated the relation between VO2peak and peak power during a maximal exercise test in persons with DS when cycling. Methods: 10 individuals with DS (20 ± 2 years) and 7 without DS (20 ± 2 years) participated in this study. They completed a maximal cycle ergometer exercise test consisting of a 3-min warm up followed by an increase in load of 16 watts every minute until exhaustion. Metabolic data were continuously collected. Aerobic economy (peak VO2 / peak watt) was calculated in both groups and compared predicted values. Results: Individuals with DS (Age 20±2 vs. 20 ± 2 years ; BMI 24.5 ± 4,1 vs. 23.3 ± 2.7) exhibited lower (p < .05) VO2peak (26.4 ± 7.0 vs. 44.1 ± 4.7 ml/kg/min) and lower peak power (102.6 ± 32.1 vs. 231.1 ± 36.1 Watt) (1.7 ± .58 v...

To inform the development of programmes to reduce sedentary behaviour, insight into the correlates is needed. Therefore, the aim of this study is to review the evidence on correlates of sedentary behaviour in adults with ID. We performed a systematic literature search in Ovid Medline, Ovid Embase, Web of Science and Google Scholar up to 19 January 2018, resulting in nine included studies that were published from 2011 to 2018. Correlates were categorized according to the ecological model. Studies predominantly focused on individual level correlates. Of those correlates studied in more than one study, having epilepsy was associated with less sedentary behaviour and inconsistent results were found for sex, genetic syndromes, weight status, physical health, mobility, level of ID, and mental health. Of the few interpersonal and environmental factors studied, only living arrangements were studied in more than one study, with inconsistent results. To date, we have limited and inconclusive evidence about correlates of sedentary behaviour in adults with ID. Only when future studies unravel correlates and determinants, across all domains of the ecological model, will the potential opportunities to improve health by reducing sedentary behaviour come within reach.
