Using self-determination theory (SDT), this study simultaneously investigated the relationships between intrinsic motivation, psychological factors (sport enjoyment, social self-efficacy), and sociorelational factors (perceived coaching behaviors) by subsequently testing whether psychological factors mediate the relationships between social-relational factors and intrinsic motivation. One hundred and twentyseven early adolescent females from several teams of the Italian Volleyball Society completed a self-report questionnaire. Results showed that female athletes’ intrinsic motivation was associated with a) sport enjoyment and b) perceived coaching behaviors (e.g., training and instruction, social support). Second, results showed that training-and-instruction coaches’ leadership style affected intrinsic motivation via the females’ enjoyment in sport. This study provided further insights into unknown associations among psychological, sociorelational factors and intrinsic motivation, highlighting the innovative role of sport enjoyment as a key factor for sustaining intrinsic motivation. Original and useful behavioral suggestions will be given to the coaches in order to sustain female athletes’ sport enjoyment and their intrinsic motivation.

The goal of this study was to identify and compare body composition (BC) variables in elite female athletes (age ± years): volleyball (27.4 ± 4.1), softball (23.6 ± 4.9), basketball (25.9 ± 4.2), soccer (23.2 ± 4.2) and handball (24.0 ± 3.5) players. Fat-free mass (FFM), fat mass, percentage of fat mass (FMP), body cell mass (BCM), extracellular mass (ECM), their ratio, the percentage of BCM in FFM, the phase angle (α), and total body water, with a distinction between extracellular (ECW) and intracellular water, were measured using bioimpedance analysis. MANOVA showed significant differences in BC variables for athletes in different sports (F60.256 = 2.93, p < 0.01, η2 = 0.407). The results did not indicate any significant differences in FMP or α among the tested groups (p > 0.05). Significant changes in other BC variables were found in analyses when sport was used as an independent variable. Soccer players exhibited the most distinct BC, differing from players of other sports in 8 out of 10 variables. In contrast, the athletes with the most similar BC were volleyball and basketball players, who did not differ in any of the compared variables. Discriminant analysis revealed two significant functions (p < 0.01). The first discriminant function primarily represented differences based on the FFM proportion (volleyball, basketball vs. softball, soccer). The second discriminant function represented differences based on the ECW proportion (softball vs. soccer). Although all of the members of the studied groups competed at elite professional levels, significant differences in the selected BC variables were found. The results of the present study may serve as normative values for comparison or target values for training purposes.

The aim of this study was to evaluate the impact of a community-based exercise program on bone mineral density and body composition in postmenopausal women with pre-diabetes and type 2 diabetes. Twenty postmenopausal women (aged 61.3 ± 6.0 years) with pre-diabetes and type 2 diabetes were randomly assigned to a community-based exercise program group (n=10) or a control group (n=10). The community-based exercise program was multicomponent, three days per week for 32 weeks, and included walking, resistance and aquatic exercises. Body composition and bone mineral density were measured pre and post-training by dual X-ray absorptiometry. In the exercise group significant increases were found in the ward’s triangle bone mineral density (+7.8%, p=0.043), and in fat-free mass (+2.4%, p=0.018). The findings suggest that regular multicomponent training is effective in preventing osteoporosis and sarcopenia among postmenopausal women with pre-diabetes and type 2 diabetes.

Urinary incontinence is complaint of any involuntary leakage of urine. Data from various sources indicate that urinary incontinence as a symptom of various disease entities should be regarded as a social disease, because they relate to more than 5% of the population. Urinary incontinence is often hidden from family and the doctor. It is estimated that about 2/3 of all cases of urinary incontinence is suppressed because of the shame and embarrassment, and insufficient information about treatment options. Between the beginning of symptoms and meeting the doctor an average time of nine years is usually observed. This ailment was twice as likely relates to women than men, and its frequency increases with age. Approximately 25% of women of childbearing age and 50% of postmenopausal women have problems with incontinence. The disease also affects younger people, about 65% of pregnant women and about 30% of women in the first year after parturition does not hold urine. In Poland it is estimated that about 5 million people suffers from this affliction. More than half of all cases of incontinence are stress and mixed urinary incontinence. In three review papers the contemporary state of knowledge on physiotherapy in stress urinary in­continence has been described. This is one of main methods of conservative treatment and prevention. In part I the contemporary recommendations by Kegel exercises in stress urinary incontinence has been described.

Approximately 25% of women of childbearing age and 50% of postmenopausal women have problems with incontinence. In Poland it is estimated that about 5 million people suffer from this affliction. More than half of all cases of incontinence are related to stress urinary incontinence. The treatment of urinary incontinence could be divided into conservative and surgical. The contemporary state of knowledge on physiotherapy - which is one of the main methods of conservative treatment and prevention - in stress urinary incontinence has been described in three review papers. Part I presented recommendations for using Kegel exercises in stress urinary incontinence. Part II focuses on current biofeedback methods
