Analysis of the correlation between knee extension torque and patellar tendon elastic property
ConclusionNo significant correlations were found between KT and PT E, suggesting that quadriceps strength is not an accurate predictor for PT mechanical properties in subjects with no specific training engagement. Habitual loading pattern can play a determinant role in PT mechanical properties, regardless of quadriceps strength. Further investigation on SSI acquisition protocols should be conducted to guarantee higher inter‐day ICC values. (Source: Clinical Physiology and Functional Imaging)

Acute physiological and perceptual responses to high ‐load resistance exercise in hypoxia
This study assessed whether hypoxia during high‐load resistance exercise could enhance the acute physiological responses related to muscular development. Twelve trained men performed exercise in three conditions: normoxia (fraction of inspired oxygen [FIO2] = 21%), moderate‐level hypoxia (FIO2 = 16%) and high‐level hypoxia (FIO2 = 13%). Exercise comprised high‐load squats and deadlifts (5 × 5 using 80% of 1‐repetition maximum with 180‐s rest). Muscle oxygenation and activation were monitored during exercise. Metabolic stress was estimated via capillary blood sampling. Perceived fatigue and soreness wer...

Reproducibility of heart rate recovery in patients with intermittent claudication
ConclusionsThe current results demonstrated that most HRR indices were highly reproducible with no systematic error, excellent reliability and good agreement in patients with IC following maximal graded exercise. (Source: Clinical Physiology and Functional Imaging)

Age ‐related differences in the motor unit action potential size in relation to recruitment threshold
Summary Motor unit action potential size (MUAPsize) versus recruitment threshold (RT) relationship analysis provides a non‐invasive measure of motor unit (MU) hypertrophy; however, this method's ability to identify MU atrophy is unknown. This investigation sought to determine if MUAPsize versus RT relationship slope (APslope) comparison could identify evidence of MU atrophy in older individuals. Surface electromyography signals were recorded from the first dorsal interosseous (FDI) of fourteen young (YG, age = 22·29 ± 2·79 years) and ten older (OG, 61·0 ± 2·0 years) subjects during a 50% maximal voluntary c...

A new equation  to predict peak VO2 in obese patients during cardiopulmonary exercise testing
Summary We aimed to develop an equation to predict peak VO2 in obese subjects undergoing CPET. In addition, we evaluated and compared three published equations. We randomized 346 obese subjects undergoing CPET into a group for developing the equation (n = 272) and a group for cross‐validation (n = 74), compared through the Bland and Altman method. Height, sex and age were responsible for 85·5% of total variability of the peak VO2. Additional 1% and 0·7% of the variability were, respectively, explained by physical inactivity and diabetes. The equation devised was as follows: The mean difference between the estimat...
