Nicotine effects on exercise performance and physiological responses in nicotine ‐naïve individuals: a systematic review
Summary The purpose of this systematic review was to evaluate the effects of smokeless forms of nicotine on physiological responses and exercise performance. Methodology and reporting were based on the PRISMA statement. The intervention was defined as any product containing nicotine that did not require smoking. Searches were conducted across two electronic databases with supplementary approaches utilized. Studies were selected following set inclusion and exclusion criteria and checked by two independent authors. A modified PEDro scale was utilized to rate study quality with studies averaging 9·3/13. Six studies assessed ...

Calculation algorithms alter the breath ‐by‐breath gas exchange values when abrupt changes in ventilation occur
Summary The automatic metabolic units calculate breath‐by‐breath gas exchange from the expiratory data only, applying an algorithm (‘expiration‐only’ algorithm) that neglects the changes in the lung gas stores. These last are theoretically taken into account by a recently proposed algorithm, based on an alternative view of the respiratory cycle (‘alternative respiratory cycle’ algorithm). The performance of the two algorithms was investigated where changes in the lung gas stores were induced by abrupt increases in ventilation above the physiological demand. Oxygen, carbon dioxide fractions and ventilatory flo...

High ‐intensity interval training using whole‐body exercises: training recommendations and methodological overview
Summary HIIT whole body (HWB)‐based exercise is a new calisthenics exercise programme approach that can be considered an effective and safe method to improve physical fitness and body composition. HWB is a method that can be applied to different populations and ages. The purpose of this study was to describe possible methodologies for performing physical training based on whole‐body exercise in healthy subjects. The HWB sessions consist of a repeated stimulus based on high‐intensity exercise that also include monitoring time to effort, time to recuperation and session time. The exercise intensity is related to the ma...

Protein timing during the day and its relevance for muscle strength and lean mass
Summary Protein consumption and its association with changes in body composition, muscle function and different strategies to optimize the muscle protein synthetic response have received considerable attention. However, we are not aware of any epidemiological study examining the time‐of‐day consumption (afternoon versus evening) of protein on strength and lean mass. The purpose was to examine the associations between afternoon and evening protein consumption, at different protein thresholds (i.e. 15, 20, 25 and 30 g), in relation to leg lean mass and knee extensor strength in men. Dietary protein consumption was asses...

An investigation into the relationship between heart rate variability and the ventilatory threshold in healthy moderately trained males
ConclusionThere does not appear to be a relationship present between the VT and the SD1 stabilization point in moderately trained healthy males, whereas the HFp stabilization point revealed a strong relationship with the VT when expressed as heart rate.

Postexercise blood flow restriction does not enhance muscle hypertrophy induced by multiple ‐set high‐load resistance exercise
Summary To test the applicability of postexercise blood flow restriction (PEBFR) in practical training programmes, we investigated whether PEBFR enhances muscle hypertrophy induced by multiple‐set high‐load resistance exercise (RE). Seven men completed an eight‐week RE programme for knee extensor muscles. Employing a within‐subject design, one leg was subjected to RE + PEBFR, whereas contralateral leg to RE only. On each exercise session, participants performed three sets of unilateral knee extension exercise at approximately 70% of their one‐repetition maximum for RE leg first, and then performed three sets fo...

Blood flow restriction attenuates eccentric exercise ‐induced muscle damage without perceptual and cardiovascular overload
Summary The aim of this study was to evaluate the acute effects of high‐intensity eccentric exercise (HI‐ECC) combined with blood flow restriction (BFR) on muscle damage markers, and perceptual and cardiovascular responses. Nine healthy men (26 ± 1 years, BMI 24 ± 1 kg m−²) underwent unilateral elbow extension in two conditions: without (HI‐ECC) and with BFR (HI‐ECC+BFR). The HI‐ECC protocol corresponded to three sets of 10 repetitions with 130% of maximal strength (1RM). The ratings of perceived exertion (RPE) and pain (RPP) were measured after each set. Muscle damage was evaluated by range of motion...
