“…Pre = Pre-intervention period, Post = Post-intervention period. Campa et al [8], and we agree with them when they suggest that this may be considered to be a consequence of constantly having to grab the handles of the suspension training system. Similar increases in grip strength after a HIIT training period were highlighted by Onambelé et al [46], when comparing their results with those of a control group and by García-Pinillos et al [15], which showed a significant increase in grip strength after HIIT.…”

“…However Ramirez et al [50], in a study with the same intensity of HIIT and the same duration of intervention did not find significant improvements in waist and hip circumference in adults with metabolic syndrome and Bartlett et al [5], in a recent study involving elderly people over 64 years, described no significant improvement in fat percentage after 10 weeks of HIIT intervention. On the other hand, very few studies have analyzed the effects of suspension training, especially in older adults, and thus a recent study performed on older women (aged 66.1 ± 4.7 years) showed that a 12-week suspension exercise training program led to significant decrease in percentage of fat mass, as well as in triceps, biceps and subscapular skinfolds [8].…”

This study aimed to evaluate the effects of a 12-week high-intensity interval exercise (HIIT) training program involving suspension exercises (TRX) on the muscle strength, body composition, gait speed, and quality of life of older adults. A total of 82 older adults were randomly assigned to 3 groups: a HIIT group (n=28), a continuous intensity training group (MIIT group, n=27), or a control group (CG, n=27). Compared to MIIT and CG, participants of the HIIT group showed significant post-intervention improvements in BMI (p=.002 and p<.001, respectively) and gait speed (p<.001 for both). Handgrip strength increase was also observed after HIIT (p=.002), but no differences were observed with MIIT and CG. Compared with MIIT and control groups, HIIT showed improvements in the SF-36 domains: general health (p<.001 for both) health changes (p<.001 for both), vitality (p=.002 and p=.001 respectively) and physical functioning (p=.036 and p<.001 respectively). Our results suggest that a HIIT training program with TRX have benefits in BMI, handgrip strength, gait speed, and quality of life in older adults.

“…Bioelectrical impedance analysis (BIA) has been widely used as a rapid, safe and non-invasive method for monitoring active adults performing recreational exercise and elite athletes [4][5][6] and in estimating body composition and nutritional status in healthy non-athletes and adults with clinical conditions [7][8][9]. Alternating current is introduced into the body by bioimpedance electronic devices at single or multiple frequencies.…”

The aims of this study were to analyze the usefulness of raw bioelectrical impedance (BI) parameters in assessing water compartments and fluid distribution in athletes. A total of 202 men and 71 female athletes were analyzed. Total body water (TBW) and extracellular water (ECW) were determined by dilution techniques, while intracellular water (ICW) was calculated. Fluid distribution was calculated as the ECW/ICW ratio (E:I). Phase angle (PhA), resistance (R) and reactance (Xc) were obtained through BI spectroscopy using frequency 50kHz. Fat (FM) and fat-free mass (FFM) were assessed by dual-energy X-ray absorptiometry. After adjusting for height, FM, FFM, age and sports category we observed that: PhA predicted ICW (females: β = 1.62, p < 0.01; males: β = 2.70, p < 0.01) and E:I (males and females: β = −0.08; p < 0.01); R explained TBW (females: β = −0.03; p < 0.01; males: β = −0.06; p < 0.01) and ECW (females: β = –0.02, p < 0.01; males: β = −0.03, p < 0.01) and ICW (females: β = –0.01, p < 0.053; males: β = –0.03 p < 0.01); and Xc predicted ECW (females: β = −0.06, p < 0.01; males: β = −0.12, p < 0.01). A higher PhA is a good predictor of a larger ICW pool and a lower E:I, regardless of body composition, age, height, and sports category. Lower R is associated with higher water pools whereas ECW expansion is explained by lower Xc. Raw BI parameters are useful predictors of total and extracellular pools, cellular hydration and fluid distribution in athletes.

“…The ICW/ECW ratio is identified by the bioelectrical phase angle (PA), which is calculated as the arctangent of Xc/R × 180 • /π [5][6][7]. An increase in ICW/ECW can be a consequence of gain in muscle mass due to physical activity [8][9][10][11]. However, the analysis of only the PA leads to interpretation errors.…”

Bioimpedance standards are well established for the normal healthy population and in clinical settings, but they are not available for many sports categories. The aim of this study was to develop reference values for male and female athletes using classic bioimpedance vector analysis (BIVA). In this study, 1556 athletes engaged in different sports were evaluated during their off-season period. A tetrapolar bioelectrical impedance analyzer was used to determine measurements of resistance (R) and reactance (Xc). The classic BIVA procedure, which corrects bioelectrical values for body height, was applied, and fat-free mass, fat mass, and total body water were estimated. In order to verify the need for specific references, classic bioelectrical values were compared to the reference values for the general male and female populations. Additionally, athletes were divided into three groups: endurance, velocity/power, and team sports. In comparison with the general healthy male and female populations, the mean vectors of the athletes showed a shift to the left on the R–Xc graph. Considering the same set of modalities, BIVA confidence graphs showed that male and female endurance athletes presented lower body fluids, fat mass, and fat-free mass than other sets of modalities. This study provides BIVA reference values for an athletic population that can be used as a standard for assessing body composition in male and female athletes.
