When catechols are methylated, they do not undergo further redox cycling thus mutagenic potentials may be reduced (Yager, 2000). The degree of oestrogenic and mutagenic potentials of individual oestrogen metabolites likely depends on their affinity to oestrogen receptors (Cavalieri et al, 2000) and...
Regular exercise, even at a recreational level, probably reduces exposure to oestrogen and thus decreases the risk of breast cancer. Increased colonic peristalsis, and thus reduced bowel transit time, might partly explain the lower risk of colon cancer in active people. Physical activity emerges as...
However, its effects on these parameters in postmenopausal breast cancer survivors are controversial or limited. Therefore, the aim of this study was to compare the effects of a 12-week progressive whole-body RET program on skeletal muscle mass, strength, and physical performance in healthy ...
High levels of vigorous activity (such as marathon training) have been linked to increased risk of upper respiratory tract infection due to reduced immune function.44 The fact that the RR of mortality in the highest category of physical activity was not the lowest (although still lower than the...
Another possible mechanism of benefit is that fibre-rich diets have been shown to improve insulin sensitivity, with an associated reduction in circulating oestrogen levels, which might suppress breast cancer growth. Colorectal cancer Bekkering et al (2006) reported on six high- fibre diet ...
Women with PCOS have an increased risk of both clinical sleep disorders and non-clinical sleep disturbance, which is mediated by hormone derangement, in particular reduced oestrogen, progesterone and melatonin levels [164]. Oestrogen is required for the metabolism of neurotransmitters (norepinephrine and...
In section 3, the same assessment is applied to the effects of physical activity in postmenopausal women. Studies of postmenopausal women are presented from the perspective of limitations of the capacity of the skeleton to adapt to mechanical stress of exercise due to altered hormonal status and in...
High levels of vigorous activity (such as marathon training) have been linked to increased risk of upper respiratory tract infection due to reduced immune function.44 The fact that the RR of mortality in the highest category of physical activity was not the lowest (although still lower than the...
Findings for three related measures of body fatness suggested that obesity is associated with a reduced risk of premenopausal breast cancer. There was no association between sports participation and breast cancer risk in these premenopausal women. The relative risk for spending an average of more than...
