Muscular strength usually decreases with age, possibly as a function of increases in body fat percentage. However, the effect of age, body fat, and lean mass on peak muscular strength or muscular fatigue is not clear. This was an observational study to determine: a) the relationship of fat mass (FM) and fat free mass (FFM) to peak knee extensor strength and fatigue in young (Y) and middle-aged (MA) women, and b) to determine differences in peak torque between Y and MA women. Participants included 132 women from two age cohorts (Y: 18-33 yrs, n = 70 and MA: 45-65 yrs, n = 62). Data from the MA cohort were collected as part of a previous study and combined with data from the Y group. Both cohorts completed physical activity questionnaires and were measured for body fat using bioelectrical impedance analysis. Both cohorts used identical procedures and machinery to assess isokinetic knee extensor peak torque (PT) at 60°/sec and to determine fatigue index (FI). FI was calculated as the percent decline of PT during 50 maximal repetitions at 240°/sec. Data were assessed for normality, and appropriate Pearson or Spearman correlations were used to compare PT and FI with body composition variables. A one-way ANOVA was used to examine differences in PT and body composition indices between age groups. In Y, FFM and FM were strongly correlated with peak torque. The correlation of FM to PT disappeared when controlling for FFM. There were no significant correlations between FFM or FM and PT in MA. PT was negatively correlated with FI in the combined groups. PT normalized for body mass and FFM were similar between age groups, but decreased with increasing size. In conclusion, PT was positively related to FFM in the combined age groups. Higher FM was not detrimental to absolute PT in Y or MA, but was detrimental to relative PT in both groups. These data suggest that perhaps FM may attenuate the normal relationship between PT and body mass.

At poor levels, it is associated with such health outcomes as diabetes and cardiovascular disease. Physical fitness testing in American youth was established on a large scale in the 1950s with an early focus on performance-related fitness that gradually gave way to an emphasis on health-related fitness. Using appropriately selected measures to collected fitness data in youth will advance our understanding of how fitness among youth translates into better health. In Fitness Measures and Health Outcomes in Youth, the IOM assesses the relationship between youth fitness test items and health outcomes, recommends the best fitness test items, provides guidance for interpreting fitness scores, and provides an agenda for needed research. The report concludes that selected cardiorespiratory endurance, musculoskeletal fitness, and body composition measures should be in fitness surveys and in schools. Collecting fitness data nationally and in schools helps with setting and achieving fitness goals and priorities for public health at an individual and national level.

Book excerpt: OBJECTIVE: The purpose of this study was to examine the relationship between strength training and body composition before and after controlling for several covariates. A cross-sectional study including 257 female subjects was conducted. METHODS: Subjects’ level of involvement in strength training was determined via questionnaire. Body composition was assessed using dual energy X-ray absorptiometry (DXA). Diet was assessed using 7-d weighed food records. RESULTS: Strong linear relationships between subjects’ level of involvement in strength training and body composition were identified. For each additional day of strength training reported per week, body fat was 1.32 percentage points lower (F = 14.8, p= 0.0002) and fat-free mass was 656.4 g (1.45 lb) higher (F = 18.9, p

It includes a clear definition of terminology and a discussion of the various methods for measuring body composition. The authored papers represent a state-of-the-art review of this controversial field and address questions such as: What is a better measure of body compositionâ€"body fat or lean body mass? Does being overweight for one's height really affect performance? The book also addresses the issue of physical appearance as it relates to body fatness and performance. It includes an in-depth discussion of many of the topics of interest to those involved in sports medicine and exercise physiology.

Book excerpt: Some decades ago, comprehensive geriatric assessment was referred to as the “new technology of geriatrics”, as research indicated many benefits of building models of care on assessment systems. Since those times, assessment-care technologies have proliferated, and in many countries have become reference standards. Work, however, continues to extend and expand geriatric assessment programs, as represented in the contents of this book.

Available in PDF, EPUB and Kindle. Book excerpt: Man develops during phylogenesis and ontogenesis as an active creature and his most striking external manifestations include physical activity. From this ensue efforts to investigate the human organism with regard to its functional diagnosis mainly during activity, in relation to the level of that physical activity. The amount and qualitative aspect of physical activity is subject to some laws associated with the developmental stage, type of higher nervous activity, health, nutritional status, external environment inc!. social position, profession, hobbies, etc.; thus it is also one of the important ecological factors. During the period before the onset of technical civilization physical fitness and performance were essential prerequisites for survival and successful existence. At present and from the aspect of the perspective development of our civilization the importance of physical fitness is pushed into the background; nevertheless adequate physical activity level is even today an important prerequisite for normal function of the organism as a whole.

This book was released on 2021 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: IntroductionThe popularity of endurance events has grown recently with an increased number of participants who have an elevated body fat percentage. The influence of chronic endurance training on adipose tissue physiology in these recreational athletes is unknown. The purpose of this investigation was to determine the effect of chronic endurance training on lipolytic rate and measurements of muscle quality (MQ) between two groups of female endurance athletes with two different levels of body fatness. Methods Female endurance athletes (N=14) with >8 yrs of training experience were divided based on body fat % into lower body fat (LBF; N=5, age=32.1±8.2yrs, BF%=19.4±4.7%, BMI=21.8±1.7kg/m2) or higher body fat (HBF; N=9, age=36.1±8.3 yrs, BF%=31.1±3.1%, BMI=23.9±3.2 kg/m2) groups based upon a BF cut-off of the 30th percentile. Two visits were completed: 1) anthropometrics, BF%, fitness, strength, and MQ testing. US histogram analysis and isokinetic force production of the rectus femoris were used to quantify MQ (IMF% and N-m/cm2), and 2) SCAAT lipolysis was measured 1 hr before, during cycling at ~70% VO2peak for 45 min, and after exercise for 2h. Results SCAAT lipolysis was not significantly different pre-exercise or not post-exercise (p > 0.05). However, there was a significant difference during exercise F(1,12) =15.01, p=.002, ƞ2=.556 (LBF=3090.6±1394.1μM, HBF=1003.2±654.3μM) between groups. There were no significant differences between groups in insulin or growth hormone (p > 0.05). There were no significant differences between groups in muscle quality with IMF% (p > 0.05). Conclusion Chronic endurance exercise training of recreational female athletes appears to alleviate the expected decrements in muscle quality due to excess adiposity among individuals in the EBF group; however, there remains a lower resting and exercise-induced lipolysis in the HBF than LBF group. Further investigations should consider possible mechanisms or lifestyle factors contributing to these observed differences
