Purpose: This study tested the hypothesis that a novel, audio-visual-directed, home-based exercise training intervention would be effective at improving cardiometabolic health and mental well-being in inactive premenopausal women. Methods: Twenty-four inactive premenopausal women (39 ± 10 y) were randomly assigned to an audio-visual-directed exercise training group (DVD; n = 12) or control group (CON; n = 12). During the 12-week intervention period, the DVD group performed thrice-weekly training sessions of 15 min. Training sessions comprised varying-intensity movements involving multiplanar whole-body accelerations and decelerations (average heart rate (HR) = 76 ± 3% HRmax). CON continued their habitual lifestyle with no physical exercise. A series of health markers were assessed prior to and following the intervention. Results: Following the DVD intervention, [HDL cholesterol] (Pre: 1.83 ± 0.45, Post: 1.94 ± 0.46 mmol/L) and mental well-being, assessed via the Warwick Edinburgh Mental Well-Being Scale, improved (P 0.05). There were no pre-post intervention changes in any of the outcome variables in the CON group (P>0.05). Conclusion: The present study suggests that a novel, audio-visual-directed exercise training intervention, consisting of varied-intensity movements interspersed with spinal and lower limb mobility and balance tasks, can improve [HDL cholesterol] and mental well-being in premenopausal women. Therefore, home-based, audio-visual-directed exercise training (45 min/week) appears to be a useful tool to initiate physical activity and improve aspects of health in previously inactive premenopausal women.

Major depression shortens life while the effectiveness of frontline treatments remains modest. Exercise has been shown to be effective both in reducing mortality and in treating symptoms of major depression, but it is still underutilized in clinical practice, possibly due to prevalent misperceptions. For instance, a common misperception is that exercise is beneficial for depression mostly because of its positive effects on the body (“from the neck down”), whereas its effectiveness in treating co...

AbstractWe aimed to perform a systematic review and meta-analysis in order to clarify the effect of programmed exercise over mild-to-moderate anxiety symptoms (ASs) in midlife and older women. A structured search of PubMed, Medline, Web of Science, Scopus, Embase, Cochrane Library, Scielo, and the US, UK and Australian Clinical Trials databases (from inception through July 27, 2017) was performed, with no language restriction using the following terms: ‘anxiety’, ‘anxiety symptoms’, ‘exercise’, ...

The review describes the fitness and health effects of recreational football in women aged 18–65 years. The review documents that 2 × 1 h of recreational football training for 12–16 weeks causes marked improvements in maximal oxygen uptake (5–15%) and myocardial function in women. Moreover, mean arterial blood pressure was shown to decrease by 2–5 mmHg in normotensive women and 6–8 mmHg in hypertensive women. This review also show that short-term (< 4 months) and medium-term (4–16 months) recrea...

Oxidative stress has been implicated in the development and progression of hypertension. This review presents a comprehensive summary of original investigations focused on exercise-induced oxidative stress in hypertensive individuals. Single bouts of exercise can induce an acute state of oxidative stress. Chronic low-to-moderate exercise training improves the antioxidative defense and reduces the disease severity. However, the data that are currently available on the chronic intensive interval t...

109 Approximately 11% of women 20 years or older have Type 2 diabetes mellitus (T2DM).1 Obesity, or excessive body fat, is linked to T2DM via insulin resistance, and being overweight or obese, and lacking regular exercise are risk factors for T2DM.2 Regular exercise is crucial in the management and prevention of T2DM. Further, losing weight and body fat can be achieved by exercise, and these outcomes reduce the risk of T2DM and cardiovascular diseases.3 Aerobic exercise improves whole body insul...

This randomized controlled study investigated the effectiveness of soccer and Zumba on fitness and health indicators in female participants recruited from a workplace. One hundred seven hospital employees were cluster-randomized to either a soccer group (SG), Zumba group (ZG), or control group (CG). Intervention effects for the two training groups were compared with CG. The training was conducted outside working hours as 2–3 1-h sessions per week for 12 weeks. Peak oxygen uptake (VO2peak), fat p...

Purpose: The present study investigated the effects of 16 weeks of small-volume, small-sided soccer training (soccer group (SG, n ¼ 13) and oscillating whole-body vibration training (vibration group (VG, n ¼ 17) on body composition, aerobic fitness, and muscle PCr kinetics in healthy inactive premenopausal women in comparison with an inactive control group (CO, n ¼ 14). Methods: Training for SG and VG consisted of twice-weekly 15-min sessions with average heart rates (HR) of w155 and 90 bpm resp...

Objectives. We analyzed the individual-level associations between participation in moderate to vigorous physical activity (MVPA) and psychological distress levels using a large, nationally representative, longitudinal sample and multivariable panel regression models.Methods. We used 3 waves of panel data from the Household, Income and Labour Dynamics in Australia Survey, consisting of 34 000 observations from 17 000 individuals and covering 2007, 2009, and 2011. We used fixed-effects panel regre...
