The aim of the study was to compare effects bilateral, unilateral, or combined bilateral and unilateral plyometric training (PT) on muscle power output, endurance, balance performance adaptations in young soccer players. Four groups players (age 11.4 ± 2.2 years) were divided into control group (CG; n = 14), (BG; 12), (UG; 16), + (B UG; 12). Players measured countermovement jump with arms, 5 multiple bounds test, 20-cm drop reactive strength index, maximal kicking velocity, sprint agility...
The purpose of the study was to compare effects progressive volume-based overload with constant on muscle explosive and endurance performance adaptations during a biweekly short-term (i.e., 6 weeks) plyometric training intervention in young soccer players. Three groups players (age 13.0 ± 2.3 years) were divided into: control (CG; n = 8) (PPT; without (NPPT; increase volume 16 jumps per leg week, an initial 80 each session). Bilateral unilateral horizontal vertical countermovement jump arms...

The effects of interday rest on adaptation to 6 weeks plyometric training in young soccer players. J Strength Cond Res 29(4): 972–979, 2015—The purpose this study was determine the short-term interposed with 24 or 48 hours between sessions explosive endurance adaptations A total 166 players, 10 17 years age, were randomly divided into 3 groups:...
Eccentric resistance training that focuses on the lengthening phase of muscle actions has gained attention for its potential to enhance strength, power, and performance (among others). This review presents a methodological proposal classifying eccentric exercises based complexity, objectives, methods, intensity. We discuss rationale physiological implications training, considering benefits risks. The proposed classification system considers exercise complexity categorizing by technical...
Introduction: Volume and intensity are major variables governing exercise training-mediated beneficial effects in both athletes patients. Although polarized endurance training optimizes maximizes physiological gains highly trained individuals, its cardiometabolic protective-effects have not been established. The purpose of the present single site, randomized-controlled trial was to compare 12-weeks high-intensity interval (HIIT), moderate-intensity continuous (MICT), volume (POL) programs on...
Human performance efficiency and effectiveness in different sports depend to a large extent on the size, weight proportion of physique athlete.The aim this study was identify morphological characteristics Brazilian Jiu-Jitsu (BJJ) athletes.The sample consisted 25 highly trained male athletes who were classified according their fighting style; guard fighter (GF) vs. pass (PF).The assessed for somatotype, body composition proportionality.For whole group somatotype 2.23±0.68,6.33±1.14,...

Abstract Background To validate the traditional talk test (TTT) and an alternative (ATT; using a visual analog scale) in overweight/obese (OW-OB) patients to establish its accuracy determining aerobic training zones. Methods We recruited 19 subjects aged 34.9 ± 6.7 years, diagnosed with overweight/obesity (BMI 31.8 5.7). Every subject underwent incremental cycloergometric tests for maximal oxygen consumption, TTT randomized order. At end of each stage during TTT, read out loud 40 words text...
Lower-limbs appendicular muscle mass is a key body composition trait related to health and performance. Considering the relevance of lower-limbs in soccer players, assessment monitoring this variable with low-cost tool would be great value order improve performance through training nutritional interventions. This study aimed develop multiple regression model validate, dual-energy X-ray absorptiometry, novel equation predict young players using anthropometric variables. Forty-two Chilean...
Background: Assessments of muscle strength help prescribe and monitor training loads in cyclists (e.g., triathletes). Some methods include repetition maximum, joint isokinetic tests, indirect estimates. However, their specificity for cycling’s dynamic force application competitive cadences is lacking. This study aims to determine the influence cycling peak (cIPF) at different on aerobic performance-related variables trained triathletes. Methods: Eleven male athletes (33 ± 9.8 years, 173.1...
