Following prescreening, 102 subjects underwent anthropometric measurements, dual-energy X-ray absorptiometry, and strength and aerobic exercise testing. Randomized subjects (male RET, n = 16; female RET, n = 19; male AET, n = 16; and female AET, n = 25) completed supervised and periodized exercise programs (AET, 30-50 min cycling at 70%-75% maximal heart rate; RET, 2-4 sets × 8-10 repetitions of 5-7 exercises at 70%-75% 1 repetition maximum) or a nonexercising control condition (male CON, n = 13 and female CON, n = 13). Changes in absolute and relative TB-FM and TB-FFM and ROI-FM and ROI-FFM were determined. At baseline, and although matched for age and body mass index, males had greater strength, aerobic fitness, body mass, absolute and relative TB-FFM and ROI-FFM, but reduced absolute and relative TB-FM and ROI-FM, compared with females (p < 0.05). After training, both female exercise groups showed equivalent or greater relative improvements in strength and aerobic fitness than did the male exercise groups (p < 0.05); however, the male exercise groups increased TB-FFM and reduced TB-FM more than did the female exercise groups (p < 0.05). Male AET altered absolute FM more than male RET altered absolute FFM, thus resulting in a greater enhancement of relative FFM. Despite equivalent or greater responses to RET or AET by female subjects, the corresponding respective increases in FFM or reductions in FM were lower than those in males, indicating that a biased dose-response relationship exists between sexes following 10 weeks of exercise training. ]]> Fri, 20 Apr 2012 03:15:18 -0500 http://fitmarker.com/weight-loss/effects-of-resistance-or-aerobic-exercise-training-on-total-and-regional-body-composition-in-sedentary-overweight-middle-aged-adults/ http://fitmarker.com/weight-training/effects-of-weightlifting-vs-kettlebell/ The Abstract "The present study compared the effects of six weeks of weightlifting plus traditional heavy resistance training exercises vs. kettlebell training on strength, power, and anthropometric measures. Thirty males were randomly assigned to one of two groups: 1) weightlifting (n = 13; mean ± SD, age: 22.92 ± 1.98 y; body mass: 80.57 ± 12.99 kg; height: 174.56 ± 5.80 cm); or 2) or kettlebell (n = 17; mean ± SD, age: 22.76 ± 1.86 y; body mass: 78.99 ± 10.68 kg; height: 176.79 ± 5.08 cm) and trained two times a week for six weeks. A linear periodization model was used for training; weeks 1-3 volume was 3×6 (kettlebell swings or high pull), 4×4 (accelerated swings or power clean), and 4×6 (goblet squats or back squats) and volume increased during weeks 4-6 to 4×6, 6×4, and 4×6, respectively. Participants were assessed for height (cm), body mass (kg), and body composition (skinfolds). Strength was assessed by the back squat 1RM while power was assessed by the vertical jump and power clean 1RM. The results of this study indicated that short-term weightlifting and kettlebell training were effective at increasing strength and power. However, the gain in strength using weightlifting movements was greater than that for kettlebell training. Neither method of training led to significant changes in any of the anthropometric measures. In conclusion, 6 weeks of weightlifting induced significantly greater improvements in strength compared to kettlebell training. No between-group differences existed for the vertical jump or body composition." ]]> Tue, 10 Apr 2012 21:49:15 -0500 http://fitmarker.com/weight-training/effects-of-weightlifting-vs-kettlebell/ http://fitmarker.com/supplementation/dietary-supplements-for-improving-body-composition-where-is-the-evidence/ Abstract Weight-loss supplements typically fall into 1 of 4 categories depending on their hypothesized mechanism of action: products that block the absorption of fat or carbohydrate, stimulants that increase thermogenesis, products that change metabolism and improve body composition, and products that suppress appetite or give a sense of fullness. Each category is reviewed, and an overview of the current science related to their effectiveness is presented. While some weight-loss supplements produce modest effects (<2 kg weight loss), many have either no or few randomized clinical trials examining their effectiveness. A number of factors confound research results associated with the efficacy of weight-loss supplements, such as small sample sizes, short intervention periods, little or no follow-up, and whether the supplement is given in combination with an energy-restricted diet or increased exercise expenditure. There is no strong research evidence indicating that a specific supplement will produce significant weight loss (>2 kg), especially in the long term. Some foods or supplements such as green tea, fiber, and calcium supplements or dairy products may complement a healthy lifestyle to produce small weight losses or prevent weight gain over time. Weight-loss supplements containing metabolic stimulants (e.g., caffeine, ephedra, synephrine) are most likely to produce adverse side effects and should be avoided. ]]> Mon, 09 Apr 2012 09:28:20 -0500 http://fitmarker.com/supplementation/dietary-supplements-for-improving-body-composition-where-is-the-evidence/ http://fitmarker.com/weight-loss/new-exercise-hormone-found/ Wed, 18 Jan 2012 09:07:16 -0600 http://fitmarker.com/weight-loss/new-exercise-hormone-found/ http://fitmarker.com/fat-loss/best-cardio-for-torching-belly-fat-hiit-for-weight-loss/ Fri, 09 Dec 2011 09:17:06 -0600 http://fitmarker.com/fat-loss/best-cardio-for-torching-belly-fat-hiit-for-weight-loss/ http://fitmarker.com/fad-diets/feds-say-hcg-diet-remedies-are-illegal/ Tue, 06 Dec 2011 19:16:43 -0600 http://fitmarker.com/fad-diets/feds-say-hcg-diet-remedies-are-illegal/
