The pelvic floor is a group of muscles and connective tissue that span the area of the pelvis to support your internal reproductive organs and to control the anal sphincter, urethra, vaginal opening and blood flow to the penis. Your pelvic floor regulates major bodily functions including urination, defecation and you guessed it-- sexual function! Stop and take a deep breath in, and out. With your next inhale, squeeze the muscles you would use to stop your pee, and hold them in. As you exhale, release those muscles.

Adequate muscle mass is important for normal physical function and whole-body intermediary metabolism including fuel metabolism. Men have more muscle mass than women, and obese people have a greater than expected muscle mass for their height compared to lean individuals. However, this increase in muscle mass is less in women than in men. In contrast, loss of muscle mass during fasting or chronic underfeeding is greater in men and lean persons than in women and obese persons. The mechanisms responsible for these differences in muscle mass regulation during anabolic and catabolic conditions are not known. The main purpose of the proposed studies is to determine the effects of sex and adiposity on changes in skeletal muscle protein synthesis MPS in response to the major physiological conditions that stimulate i.

The purpose of this study was to determine and compare thigh muscle volumes MVs , and sprint mechanical properties and performance between male and female national-level sprinters. We also studied possible relationships between thigh MVs and sprint performance. Nine male and eight female national-level sprinters participated in the study.

In spite of some dissociation between muscle mass and strength, muscle strength is often used as a proxy to identify individuals with low muscle mass sarcopenia. Thus, the aim of the present study was to investigate the relationship between muscle strength and the appendicular lean body mass index app LBMI. One hundred and five individuals were recruited. Knee extension and handgrip strength were measured.
