[Update on Current Care Guideline: Physical activity and exercise training for adults in sickness and in health]. / KÄYPÄ HOITO -SUOSITUS (Päivitystiivistelmä). Liikunta.

The purpose of the guideline is to promote physical activity in the prevention, treatment and rehabilitation of diseases. Physical activity plays a key role in the management of several chronic noncommunicable diseases. In this guideline, the following diseases are discussed: endocrinological, cardiovascular, musculoskeletal and respiratory diseases, as well as depression and cancer. In addition, physical activity during pregnancy and in senior citizens is reviewed. Exercise counseling should be included as part of disease management and lifestyle guidance.

Differential effects of oral and transdermal estradiol treatment on circulating estradiol fatty acid ester concentrations in postmenopausal women.

Estradiol fatty acid esters are potent lipophilic estrogens with antioxidant properties, transported by lipoproteins in blood. We investigated effects of oral and transdermal estradiol replacement therapy on concentrations of estradiol fatty acid esters in serum in postmenopausal women in a double-blind, randomized fashion. The first group (n = 9) received oral (2 mg/d); the second (n = 10), transdermal estradiol (patch delivering 50 microg/d); and the third group (n = 7), placebo treatment for 12 wk. After extraction of serum and separation of esterified estradiol from nonesterified estradiol, the concentration of saponified estradiol esters was measured by time-resolved fluoroimmunoassay. In the oral estradiol group, the median serum estradiol fatty acid ester concentration rose by 27%, from 77 to 98 pM (P = 0.028) but remained unchanged in the transdermal estradiol and placebo groups. The median concentrations of serum nonprotein-bound estradiol increased similarly in the oral and transdermal estradiol groups. The change in serum estradiol ester concentrations during treatment, but not that of nonesterified estradiol, correlated positively with enhanced forearm blood flow responses in vivo. These data raise the possibility that an increase in serum estradiol fatty acid esters may contribute to beneficial effects of oral estradiol treatment, compared with an equipotent dose of transdermal estradiol.

Moderate energy restriction with high protein diet results in healthier outcome in women.

BACKGROUND: The present study compares two different weight reduction regimens both with a moderately high protein intake on body composition, serum hormone concentration and strength performance in non-competitive female athletes. METHODS: Fifteen normal weighted women involved in recreational resistance training and aerobic training were recruited for the study (age 28.5 +/- 6.3 yr, height 167.0 +/- 7.0 cm, body mass 66.3 +/- 4.2 kg, body mass index 23.8 +/- 1.8, mean +/- SD). They were randomized into two groups. The 1 KG group (n = 8; energy deficit 1100 kcal/day) was supervised to reduce body weight by 1 kg per week and the 0.5 KG group (n = 7; energy deficit 550 kcal/day) by 0.5 kg per week, respectively. In both groups protein intake was kept at least 1.4 g/kg body weight/day and the weight reduction lasted four weeks. At the beginning of the study the energy need was calculated using food and training diaries. The same measurements were done before and after the 4-week weight reduction period including total body composition (DXA), serum hormone concentrations, jumping ability and strength measurements RESULTS: During the 4-week weight reduction period there were no changes in lean body mass and bone mass, but total body mass, fat mass and fat percentage decreased significantly in both groups. The changes were greater in the 1 KG group than in the 0.5 KG group in total body mass (p < 0.001), fat mass (p < 0.001) and fat percentage (p < 0.01). Serum testosterone concentration decreased significantly from 1.8 +/- 1.0 to 1.4 +/- 0.9 nmol/l (p < 0.01) in 1 KG and the change was greater in 1 KG (30%, p < 0.001) than in 0.5 KG (3%). On the other hand, SHBG increased significantly in 1 KG from 63.4 +/- 17.7 to 82.4 +/- 33.0 nmol/l (p < 0.05) during the weight reducing regimen. After the 4-week period there were no changes in strength performance in 0.5 KG group, however in 1 KG maximal strength in bench press decreased (p < 0.05) while endurance strength in squat and counter movement jump improved (p < 0.05) CONCLUSION: It is concluded that a weight reduction by 0.5 kg per week with ~1.4 g protein/kg body weight/day can be recommended to normal weighted, physically active women instead of a larger (e.g. 1 kg per week) weight reduction because the latter may lead to a catabolic state. Vertical jumping performance is improved when fat mass and body weight decrease. Thus a moderate weight reduction prior to a major event could be considered beneficial for normal built athletes in jumping events.
