Seven male weightlifters (age: 28.3 ± 5.7 years, body mass: 80.5 ± 6.7 kg, body height: 1.73 ± 0.07 m) participated in this study. Measurements were performed 2 weeks prior to the national championship and included the countermovement jump (CMJ), the squat jump (SJ), the DJ from three different drop heights (20, 30, and 40 cm), and the isometric peak torque (IPT) and RTD. Performance in CMJ and SJ was significantly correlated with weightlifting performance (r ranging from 0.756 to 0.892). Significant correlations were found between weightlifting performance with DJ contact time (r ranging from −0.759 to −0.899) and RSI (r ranging from 0.790 to 0.922). Moreover, the best RSI was significantly correlated with the snatch (r = 0.921, p = 0.003) and...

Methods: Thirty six sedentary women were randomly assigned to control (n=11), and stair climbing at home (n=13) or in the laboratory (n=12). Over 8-weeks, stair-climbing progressed from two ascents per day in week 1 and 2 to eight ascents per day in weeks 7 and 8, for five days/week at a stepping-rate of 90 steps/min. For the home-based stair-climbers, calculations based on the number and height of each participant's stairs matched the vertical displacement occurring with the laboratory stair-machine (143 stairs; 23cm each). Findings: The stair-climbing interventions reduced weight, percentage body fat and skinfold thickness, as well as improving fitness (increased VO2max, reduced lactate production) and serum lipid profiles (increased HDL, reduced LDL). Laboratory and home based interventions were equivalent for these variables. Conclusions: This study re...

The aim, therefore, of the present study was to examine the effect of 8 weeks of an individualized corrective exercise intervention program on musculoskeletal asymmetries in young soccer players. Materials and Methods: Eighty young male soccer players (age: 14.4 ± 1.2 years; body height: 166.3 ± 9.6 cm; body mass: 59.1 ± 11.5 kg) participated in the current laboratory-based study. A battery of postural and musculoskeletal asymmetry evaluations were initially performed. After the completion of the initial assessment, each player was provided with an individual musculoskeletal asymmetry corrective exercise intervention program which lasted for 8-weeks, with the aim of restoring muscular asymmetri...

The current retrospective study aims to examine the effect of the laparoscopic gastric sleeve (LGS) operation on circulating blood HbA1c and fast blood sugar in patients with obesity and with or without diabetes mellitus. Methods: Circulating blood HbA1c and FBS of eight hundred sixty-three (n=863) patients with obesity were evaluated before (baseline) and less than 3 months, 3 to 6 months, 6 to 12 months, 1 to 2 years, and 2 to 5 years of operation. Results: The results show a positive effect on the time-varying effect of LGS on the profile of FBS and HbA1c for patients with obesity who underwent this procedure. There was an improvement in the mean value of FBS from 111.79 mg/dl at the baseline point before an operation, to 86.49 mg/dl after over 2 to 5 years of operation (P < 0.05). Whereas HbA1c was also improved by decreasing from 6.54 mg/dl to 5.27 mg/dl (P < 0.05) in the same period. Conclusion: In both diabetic and non-diabetic patients with obesity, the current study found that LGS is an efficient approach for helping to reduce fasting blood glucose levels and HbA1c over the course of the 5-year evaluation period.

Nevertheless, iron deficiency is one of the most common nutritional deficiencies in general, and in patients with obesity, particularly following bariatric surgeries. Several health recommendations worldwide urged for the effectiveness of iron supplementation after bariatric surgeries. Short term and long-term data on iron anemia deficiency after LGS are generally lacking. This study aimed to examine the effect within (3 months, 6 months, 1 year, 2 years and 5 years) on iron deficiency in patients with obesity who underwent LGS operation. Subjects and Methods: Cohort Retrospective observational study design for 5 years follow up, from 2015 to 2020. The study was used unidentified recorded data from the hospital of 863 patients with obesity who underwent LGS with/without a history of iron deficiency anemia as operation day as a baseline point, within 3 months, 6 months, 12 months, 2 years, and 5 years postoperatively. Results: the results showed that the average value of serum iron before surgery was 62.32 ug/dl, then the mean value had slightly decreased during the first three months of operation. Then, the mean value of iron slightly increased from 3 months up to 12 months, postoperatively. After 1 year up to 5 years, postoperatively, the mean value of iron again slightly decreased to reach 52.60 ug/dl. Conclusion: LGS, as an effective and common bariatric surgery method, does not significantly affect the levels of serum iron, during 5 years postoperatively in patients with obesity, with or without iron anemia deficiency.

The aim of the study is to investigate the relationship between lean mass, quadriceps cross sectional area (CSA), and muscle architecture with weightlifting performance in female weightlifters. Eight well-trained female weightlifters (age 23.5 ± 6.3 years, maximum total lifting performance = 147.4 ± 34.1 kg) participated in the study. Five of the athletes were members of the national team and three were among the nation’s top-five performers of the respective body-weight category. Measurements included maximum lifting performance in snatch and clean and jerk, body composition (dual x-ray absorptiometry), vastus lateralis (VL) muscle architecture, vastus intermedius (VI) muscle thickness and quadriceps muscles’ CSA and countermovement jump (CMJ). Very large to nearly perfect correlations were found between snatch and clean ...

Fifty male soccer players, all members of the under 17 (U17) and 15 (U15) National teams of Cyprus, were initially evaluated for thoracic kyphosis, lumbar lordosis and scoliosis asymmetries. Based on the spinal asymmetries’ initial evaluation, soccer players were categorized into the asymmetry group (AG) and normal group (NG) per spinal asymmetry. Hamstring and lower-back flexibility, countermovement jump (CMJ) and lower body isokinetic maximum force were evaluated between AG and NG. CMJ with arm swing was lower in kyphotic posture AG compared with the NG (AG: 41.70 ± 3.59 cm, NG: 44.40 ± 4.34 cm; p = 0.028). Single leg CMJ was lower in both legs in scoliotic posture AG compared with the NG (right: AG: 17.42 ± 1.86 cm, NG: 19.16 ± 2.42 cm, p = 0.008, left: AG: 17.54 ± 1.33 cm, NG: 19.97 ± 2.91 cm; p = 0.002). Sit-and-reach flexibility was lower in scoliotic posture AG (AG: 20.44 ± 5.76 cm, NG: 24.82 ± 6.83 cm; p = 0.024) and higher in lordotic posture AG (AG: 25.95 ± 6.59 cm, NG: 21.73 ± 6.45 cm; p = 0.04) both compared with the NG. No significant difference was found for quadriceps and hamstrings concentric peak torque between the AG and NG (p > 0.05). The current study revealed that kyphotic and scoliotic posture asymmetries deteriorate neuromuscular explosiveness performance and diminish lower limbs’ flexibility in young International-level soccer players.

Sixteen male participants were equally assigned into the inter-repetition rest and the traditional group. In both groups, training included the bench press exercise performed with 4 sets of 6 maximum repetitions, two training sessions per week. Twenty-second inter-repetition rest was employed for the inter-repetition rest group only. Measurements before and after the training period included maximum strength in the bench press, the isometric upper body rate of force development and peak force and triceps brachii muscle architecture. Maximum strength increased significantly in both groups (inter-repetition rest group: 21.5 ± 5.7% vs. traditional group: 13.5 ± 7.2%, p < 0.05), however, the maximum strength percentage increase was greater in the inter-repetitio...

Thirteen adolescent swimmers were randomly assigned to perform either a DLP or SP 24 h prior to a 50 m sprint crawl time-trial. Baseline measurements included a 50 m sprint crawl time-trial as a control (C) condition, the evaluation of body composition, countermovement jump (CMJ), isometric peak torque (IPT), and rate of torque development (RTD). Rating of perceived exertion (RPE) was obtained following the DLP and SP programs. Both DLP and SP significantly decreased the 50 m crawl time-trial, by −2.51 ± 2.43% and −2.59 ± 1.89% (p < 0.01), respectively, compared with the C time-trial. RPE was not different between DLP and SP (p = 0.919). CMJ performance remained unchanged after DLP and SP programs compared with the C trial (p > 0.05). The percentage decrease in the 50 m crawl after DLP was significantly...

Twenty three players (mean±SD) were randomly assigned into flexibility (Flex) and control (Con) groups (Flex group: N.=12, age 16.1±0.6 years; height 1.71±.06 m; body mass 62.4±7.5 kg; peak oxygen uptake [V̇O2peak] 55.8±4.1 ml.kg-1.min-1; Con group: N.=11, age 15.9±0.6 years; height 1.73±.07 m; body mass 61.5±5.6 kg; V̇O2peak 54.2±5.2 mL.kg-1.min-1). The Flex group performed a specific static stretching training-program before and after each training session, for four weeks (4 days/week). The two groups performed two series of anthropometrics and physical-fitness tests prior to and following the application of the stretching training performed on the Flex group. There were initially no main treatment effects on aerobic capacity (V̇O2peak), on 10-m sprint and on Broad-jump. However, sit-and-reach flexibility, 35m sprint and agility ...

Notably, the effect of such programs on aerobic fitness is still controversial. The aim of this study was to examine the effects of both programs on physical fitness and body composition on previously inactive adult women. METHODS Twenty-six women (39.8 ± 9.1y) were assigned to a LLHR program, and sixteen women (39.1 ± 12.2y) were assigned to a Pilates program. Both programs were performed in a group setting, 3 times per week for 3 months. Aerobic fitness, flexibility, handgrip strength and lower extremities explosiveness were assessed by a battery of field testing. Total body fat and trunk fat levels were assessed by bioelectrical impedance analysis. Heart rate response during exercise was recorded once every month by using a telemetry system. RESULTS Aerobic fitness, lower extremities explosive power, left arm handgrip strength and body composition significantly improved in the LLHR group; while flexibility significantly improved only in the Pilates group, following the intervention period (p < 0.05). LLHR was superior to the Pilates program in improving aerobic fitness and body composition; whilst Pilates was superior in improving flexibility (p < 0.05). CONCLUSION LLHR group-based exercise programs may improve various aspects of physical fitness, including aerobic fitness, in inactive adult women. This medium-intensity form of exercise is generally well tolerated and might be used as an option for women who cannot perform training on higher intensities. In contrast, the Pilates program failed to improve physical fitness-related parameters except flexibility levels.
