- The present study examined the effects of short-term recreational football training on blood pressure (BP), fat mass, and fitness in sedentary, 35-50-year-old premenopausal women with mild hypertension. Forty-one untrained, hypertensive women were randomized into a football training group (n=21; FTG) and a control group (n=20; CON). FTG performed 45 +/- 1 1-h small-sided football training sessions during the 15-week intervention period. BP, body composition (dual-energy x-ray absorptiometry), blood lipid profile, and fitness level were determined pre- and post-intervention. After 15 weeks, systolic and diastolic BP, respectively, were lowered more (P<0.05) in FTG (-12 +/- 3 and -6 +/- 2mmHg) than in CON (-1 +/- 1 and 1 +/- 2mmHg). Total body fat mass decreased more (P<0.05) in FTG than in CON during the 15-week intervention period (-2.3 +/- 0.5kg vs 0.4 +/- 0.3kg). After 15 weeks, both total cholesterol (-0.4 +/- 0.1mmol/L vs 0.1 +/- 0.2mmol/L) and triglyceride (-0.2 +/- 0.1mmol/L vs 0.3 +/- 0.2mmol/L) were lowered more (P<0.05) in FTG than in CON. Yo-Yo intermittent endurance level 1 test performance increased more (P<0.05) in FTG than in CON (111 +/- 18% vs 1 +/- 3%) during the 15-week intervention period. In conclusion, short-term football training resulted in a marked reduction in BP and induced multiple improvements in fitness and cardiovascular health profile of untrained, premenopausal women with mild hypertension.

- To test the hypothesis that high-intensity swim training improves cardiovascular health status in sedentary premenopausal women with mild hypertension, sixty-two women were randomized into high-intensity (n = 21; HIT), moderate-intensity (n = 21; MOD), and control groups (n = 20; CON). HIT performed 6-10 × 30 s all-out swimming interspersed by 2 min recovery and MOD swam continuously for 1 h at moderate intensity for a 15-week period completing in total 44 ± 1 and 43 ± 1 sessions, respectively. In CON, all measured variables were similar before and after the intervention period. Systolic BP decreased (P < 0.05) by 6 ± 1 and 4 ± 1 mmHg in HIT and MOD; respectively. Resting heart rate declined (P < 0.05) by 5 ± 1 bpm both in HIT and MOD, fat mass decreased (P < 0.05) by 1.1 ± 0.2 and 2.2 ± 0.3 kg, respectively, while the blood lipid profile was unaltered. In HIT and MOD, performance improved (P < 0.05) for a maximal 10 min swim (13 ± 3 % and 22 ± 3 %), interval swimming (23 ± 3 % and 8 ± 3 %), and Yo-Yo IE1 running performance (58 ± 5 % and 45 ± 4 %). In conclusion, high-intensity intermittent swimming is an effective training strategy to improve cardiovascular health and physical performance in sedentary women with mild hypertension. Adaptations are similar with high- and moderate-intensity training, despite markedly less total time spent and distance covered in the high-intensity group. © 2014 Magni Mohr et al.

- We examined the effects of 16 weeks of football training and dietary advice on blood glucose control and health status in 55- to 70-year-old women and men with prediabetes. Fifty participants with prediabetes (age; 61 +/- 6 years, BMI; 29.6 +/- 4.7; VO2max 22.3 +/- 5.7 mL.min(-1).kg(-1)) were randomized into a football and dietary ad- vice group (F+D; n = 27) and a dietary advice group (D; n = 23). F+D performed football training (twice weekly 30- to 60-minutes sessions) and received dietary advice, while D only received dietary advice. An oral glucose tolerance test (OGTT) was completed pre and post the 16-week period. Body composition, blood pressure, and maximal oxygen uptake (VO2max) were additionally measured. Both groups demonstrated a decrement (P < .05) in fasting blood glucose (-0.4 +/- 0.5 mmol.L-1) and lowered blood glucose throughout OGTT. F+D displayed lower values than D (P < .05) after 60 minutes (9.0 +/- 2.7 vs 10.6 +/- 2.9 mmol.L-1) and 120 minutes (5.7 +/- 1.6 vs 7.5 +/- 2.4 mmol.L-1). VO(2max )increased by 14% in F+D, with a higher (P < .05) change score than in D (2%). Mean arterial pressure declined more (P < .05) in F+D than in D (-8 +/- 9 vs -4 +/- 11 mm Hg). Fat loss was greater (P < .05) in F+D than in D (-3.4 +/- 2.8 vs -1.2 +/- 2.0 kg), and the increase in lean body mass was also greater (P < .05) in F+D than in D (0.7 +/- 1.5 vs -0.3 +/- 1.6 kg). In conclusion, football training combined with dietary advice has broad-spectrum effects on metabolic and cardiovascular health profile with greater overall effects than professional dietary advice per se for 55- to 70-year-old women and men with prediabetes.

Tidskriftsartikel (refereegranskat)abstract
- We tested the hypothesis that low-volume high-intensity swimming has a larger impact on insulin sensitivity and glucose control than high-volume low-intensity swimming in inactive premenopausal women with mild hypertension. Sixty-two untrained premenopausal women were randomised to an inactive control (n = 20; CON), a high-intensity low-volume (n = 21; HIT) or a low-intensity high-volume (n = 21; LIT) training group. During the 15-week intervention period, HIT performed 3 weekly 6-10 x 30-s all-out swimming intervals (average heart rate (HR) = 86 +/- 3 % HRmax) interspersed by 2-min recovery periods and LIT swam continuously for 1 h at low intensity (average HR = 73 +/- 3 % HRmax). Fasting blood samples were taken and an oral glucose tolerance test (OGTT) was conducted pre- and post-intervention. After HIT, resting plasma [insulin] was lowered (17 +/- 34 %; P < 0.05) but remained similar after LIT and CON. Following HIT, 60-min OGTT plasma [insulin] and [glucose] was lowered (24 +/- 30 % and 10 +/- 16 %; P < 0.05) but remained similar after LIT and CON. Total area under the curve for plasma [glucose] was lower (P < 0.05) after HIT than LIT (660 +/- 141 vs. 860 +/- 325 mmol min L-1). Insulin sensitivity (HOMA-IR) had increased (P < 0.05) by 22 +/- 34 % after HIT, with no significant change after LIT or CON, respectively. Plasma soluble intracellular cell adhesion molecule 1 was lowered (P < 0.05) by 4 +/- 8 and 3 +/- 9 % after HIT and CON, respectively, while plasma soluble vascular cell adhesion molecule 1 had decreased (P < 0.05) by 8 +/- 23 % after HIT only. These findings suggest that low-volume high-intensity intermittent swimming is an effective and time-efficient training strategy for improving insulin sensitivity, glucose control and biomarkers of vascular function in inactive, middle-aged mildly hypertensive women.

- The study tested the hypothesis that long-term soccer training has positive impact on cardiovascular profile, body composition, bone health, and physical capacity in inactive, pre-menopausal women with mild hypertension. The study applied a randomized controlled design in which physically inactive middle-aged women were separated into a soccer training group (n=19; SOC) and a control group (n=12; CON). SOC performed 128 +/- 29 (+/- SD) one-h small-sided soccer training sessions over one year. Blood pressure, body composition, blood lipid profile, and fitness level were determined pre- and post-intervention. Over one year, mean arterial pressure decreased more in SOC than in CON (-5 +/- 7 vs +4 +/- 5mmHg; P<.05). Total-body fat mass decreased more (P<.05) in SOC than in CON (-2.5 +/- 2.5 vs +0.6 +/- 3.2kg; P<.05), while the change scores for lean body mass were not significantly different in SOC (2.6 +/- 2.7kg) compared to CON (1.1 +/- 1.9kg, P=.09). Over one year, change scores in whole-body bone mineral density (0.004 +/- 0.032 vs -0.019 +/- 0.026gcm2) as well as bone mineral content (30 +/- 70 vs -39 +/- 113g) were positive in SOC compared to CON (P<.05). Post-intervention plasma triglycerides decreased more (-0.1 +/- 0.7 vs +0.2 +/- 0.2mmolL-1) and HDL cholesterol increased more (0.2 +/- 0.7 vs -0.2 +/- 0.2mmolL-1) in SOC than in CON (P<.05). Yo-Yo intermittent endurance level 1 (122 +/- 105 vs 2 +/- 21%) and 20-m sprint performance (6 +/- 6 vs -1 +/- 2%) increased more (P<.05) in SOC than in CON. In conclusion, long-term soccer training resulted in broad-spectrum improvements in the health profile of untrained, pre-menopausal women with mild hypertension, including cardiovascular, metabolic, and musculo-skeletal benefits.

- People in the Arctic as well as fishermen on the polluted Swedish east coast are highly exposed to persistent organic pollutants (POPs). These compounds have been shown to affect the sperm Y:X chromosome ratio. In present study, the aim was to investigate whether polychlorinated biphenyl (PCB) congeners and 1,1,-dichloro-2,2,-bis(p-chlorophenyl)ethane (p,p'-DDE) influence sperm sex chromosome ratio in Faroese men, and whether these men differ regarding Y:X ratio compared to Greenland Inuit and Swedish fishermen. The study population (n=449) consisted of young men from the general population (n=276) as well as proven fertile men (n=173). The Y:X ratio was assessed by fluorescent in situ hybridization. Serum concentrations of POPs were measured using gas chromatography. Associations between POP concentrations and Y:X ratio were calculated using linear and non-linear regression models as well as trend analysis and pairwise comparison of exposure data categorized into quartiles. The selected POPs were associated with Y:X ratio in fertile Faroese men, but not in the total population; p,p'-DDE (95% CI for B=-0.005 to -0.001, p=0.005) and ΣPCB (95% CI for B=-0.005 to -0.001, p=0.012). Since p,p'-DDE and ΣPCB correlated significantly (r=0.927, p<0.001), the results involving the exposure variables can be regarded as a single finding. The Y:X ratio for the total Faroese population was 0.500±0.018, which was statistically significantly lower than in both Inuit and Swedish fishermen (0.512 for both). In conclusion, Faroese men presented with lower Y:X ratio than Greenland Inuit and Swedish fishermen. Although no direct health effects are expected due to the lower Faroese Y:X ratio, it could be indicative of adverse effects on the reproductive system.
