Luigi Fattorini, Angelo Rodio
AIM: The aim of this study was to evaluate the effects of acoustic and visual pacesetters on the energy expenditure in a steady state 30-minute long cycling. METHODS: Eighteen healthy male subjects (age 27.6 ± 4.59 years; height 1.78 ± 0.07 m; body mass 80.1 ± 7.85 kg) performed a 30-minute submaximal exercise at a constant workload on a cycle ergometer. The imposed workload required a metabolic expenditure corresponding to 70% of ventilatory threshold for each subject...

BACKGROUND: The purpose of this study was to cross-validate and demonstrate how adult stature can be predicted in 13-year-old basket-ball players by using a new reference specific growth curve obtained from chronological age, and maturity of sedentary boys. METHODS: The prediction of adult stature of young male basketball players was established from the results of a longitudinal study in which we developed from 125 sedentary boys aged from 12 to 17.5 years new growth curves using chronological and biological maturation...

BACKGROUND: Diffusion tensor imaging (DTI) is a non-invasive MR technique widely employed to study muscle anatomy. DTI parameters have been use to investigate changes in microstructures dependent on demographic factors or transient condition such as exercise. The present study is aimed at investigating the diffusion parameters changes of the human calf muscles after a 3-months strength training protocol. METHODS: Ten young men were trained for improving size and strength of the medial (GCM), lateral gastrocnemius (GCL) and soleus (SL) three times a week, with at least 24 hours between training sessions, for a period of three months...

BACKGROUND: Body weight loss program may lead to a decrease in lean body mass affecting negatively muscle performance in obese subjects. Thus, the aim of this study was to examine the effect of weight loss on muscle performance in female obese subjects. METHODS: Eighty obese female adults were enrolled for a 2-month unsupervised aerobic training (UAT) plus nutritional program. In the pre- and post-intervention body composition was evaluated by hand-to-foot bioelectrical impedance method, body strength using handgrip test, and lower muscle power was assessed by a 5-repetition chair stand test (CST) and 30-s chair stand test (30sCST) wearing a dynamometer...

BACKGROUND: Assessment of percent body fat (%BF) is typically measured with bioelectrical impedance (BIA) as a proxy for dual-energy x-ray absorptiometry (DXA). Notably, poorer agreement between BIA and DXA among persons who are overweight or obese has been reported. The use of electrical impedance myography (EIM) as a proxy for DXA has not been validated. The objective was to evaluate an EIM device and two multi-frequency BIA devices with the reference standard (DXA) stratified by weight status and gender...

BACKGROUND: Boxers need to consider energy metabolism during rapid weight loss (RWL) followed by rapid weight regain. We examined the effects of RWL and a 3-h acute weight recovery on energy expenditure, carbohydrate oxidation, and fat oxidation in boxing athletes. METHODS: The analysis was based on the data of seven healthy young male athletes who underwent rapid weight loss followed by acute weight recovery. Energy expenditure was evaluated at three time points: one week prior to the acute weight loss (baseline); after the 1- week weight loss period; after a 3-h acute weight recovery period...

BACKGROUND: Low-intensity resistance exercises with blood flow restriction have been shown is effective to increase muscular strength and hypertrophy. However, the effects of combined training: one-week occlusion training with various exercise intensities by using less occlusion pressure on muscle strength improvement, fatigability and their work capacity are not clear. METHODS: Participants (n = 24) were middle-distance runners with 4-6 years of training experience...

BACKGROUND: Central aortic blood pressure (BP) is reduced after exercise. The aim of this study was to determine whether cardiorespiratory fitness relates to post-exercise reductions in aortic BP. METHODS: Sixteen young adults completed maximal exercise testing for peak oxygen uptake (VO2). Participants walked at a slow (80 steps/min, ~47% maxHR) and fast (125 steps/min, ~65% maxHR) stepping cadence for 3,000 steps on two nonconsecutive days. Before and after each walking condition, radial tonometry was used to derive aortic pressures...

BACKGROUND: A sports therapy program in type 2 diabetes helps in glucose control, but little is known how a long-term structured exercise intervention affects the parameters in this disease. Our aim was to measure the impact of a 24-week long sports therapy program in type 2 diabetes on the concentration of glucose in blood, body composition, and physical fitness level. METHODS: In this prospective longitudinal study, 208 type II diabetic patient (80 male, 128 female, aged: 61±6,86 years) were selected and randomly assigned to a control or an intervention group...

BACKGROUND: It is unknown whether a concentrated period of small-sided games and high intensity training is an effective training approach in youth soccer players. The aim of the study was to examine the effect of a concentrated period of soccer specific training on physical fitness in youth players. METHODS: Nineteen male soccer players, from two teams, participated (mean ± SD age: 16.2 ± 0.8 years; body mass: 58.2 ± 7.6 kg; height: 170.8 ± 7.7 cm). One team performed 5 days of small-sided games and high intensity training (SSG & HIT; n = 12) and the other team regular soccer training with 1 day of SSG and HIT (REG; n = 7) weekly for 4 weeks...

BACKGROUND: Runners who participate in endurance sports such as marathons or ultramarathons have superior physical capabilities and health benefits compared to others. However, they may suffer long-term effects of the negative physiological changes during long-distance running. This study aimed to examine the effects of an ultramarathon on hormone levels, and the associated risks. METHODS: Ten participants who completed a 622-km ultramarathon were included. Blood was collected pre-race, at the 300-km mark, the 622-km mark, and on the 3rd day of recovery (RD3) and the 6th day of recovery (RD6) and analyzed for human growth hormone (HGH), cortisol, beta-endorphin, serotonin, testosterone, luteinizing hormone (LH), and follicle stimulating hormone (FSH) levels...

BACKGROUND: The physical and mental health of college students tends to continuously decline worldwide. Thus, improving their health is necessary. Jazz dance may be one of the effective exercises to improve one's health. However, the effect of jazz dance exercise on different physical fitness level and whether the intensity of jazz dance exercises can improve physical and mental health simultaneously and efficiently need to be investigated. In this study, we systematically assessed the effect of jazz dance on physical and mental health of college students by a rigorous randomized, parallel-controlled design...
