In this article, the relationship between in-season training workload with changes in aerobic power (VO2m ax ), maximum and resting heart rate (HR max and HR rest ), linear sprint medium (LSM), and short test (LSS) was analyzed.Abstract:
This study sought to analyze the relationship between in-season training workload with changes in aerobic power (VO2m ax ), maximum and resting heart rate (HR max and HR rest ), linear sprint medium (LSM), and short test (LSS), in soccer players younger than 16 years (under-16 soccer players). We additionally aimed to explain changes in fitness levels during the in-season through regression models, considering accumulated load, baseline levels, and peak height velocity (PHV) as predictors. Twenty-three male sub-elite soccer players aged 15.5 ± 0.2 years (PHV: 13.6 ± 0.4 years; body height: 172.7 ± 4.2 cm; body mass: 61.3 ± 5.6 kg; body fat: 13.7% ± 3.9%; VO2m ax : 48.4 ± 2.6 mL⋅kg-1⋅min-1), were tested three times across the season (i.e., early-season (EaS), mid-season (MiS), and end-season (EnS) for VO2m ax , HR max , LSM, and LSS. Aerobic and speed variables gradually improved over the season and had a strong association with PHV. Moreover, the HR max demonstrated improvements from EaS to EnS; however, this was more evident in the intermediate period (from EaS to MiS) and had a strong association with VO2m ax . Regression analysis showed significant predictions for VO2m ax [F ( 2, 20) = 8.18, p ≤ 0.001] with an R 2 of 0.45. In conclusion, the meaningful variation of youth players' fitness levels can be observed across the season, and such changes can be partially explained by the load imposed.read more

TL;DR: In this article, the authors describe anthropometric, maturation, and somatotype differences of players based on playing positions, and analyze variations of accumulated load training (AcL) and fitness parameters between playing positions; and finally, explain the variation of maximal oxygen uptake (VO2max) and peak power (PP) through the AcL, body fat (BF), maturity, maturity, and fitness levels.

TL;DR: It is concluded that the session RPE method is a valid method of quantitating exercise training during a wide variety of types of exercise and may provide a tool to allow the quantitative evaluation of training periodization plans.

TL;DR: The authors use a more intuitive and practical approach based directly on uncertainty in the true value of the statistic, which deals with the real-world relevance of this uncertainty by taking into account values that are substantial in some positive and negative sense.

An assessment of maturity from anthropometric measurements.
TL;DR: Although the cross-validation meets statistical standards for acceptance, caution is warranted with regard to implementation and it is recommended that maturity offset be considered as a categorical rather than a continuous assessment.
