Association of cardio-pulmonary stress test parameters and heart rate recovery in obese subjects with or without type II diabetes

2016

Background and Objectives: Heart rate recovery at first (HRR-I) and second (HRR-II) minute after exercise is accurate in estimating autonomic nervous system balance, and has been related to risk of cardiovascular events. Our aim was to determine independent predictors of HRR collected during standard cardio-pulmonary stress test (CPT) in a group of overweight/obese subjects without (N=14) and with type 2 diabetes (N=19), as compared to a sample (N=15) of healthy sedentary subjects. Methods: A graded exercise test on treadmill was performed. Oxygen uptake at rest and at peak exercise (VO2max), as well as respiratory exchange ratio at peak exercise was collected. Linear and logistic regressio…

Relationship between heart rate variability and repeated sprint exercise in young soccer players

2014

Aim: The sport of soccer is characterized by neuromuscular performance resulting in short bursts interspersed by brief recovery periods over an extended period of time. Several studies suggest that the cardiac autonomic nervous system (ANS) assessed by heart rate variability (HRV) may provide useful information regarding the functional adaptations to training stimulus. Although HRV has often been associated with aerobic power and cardiovascular fitness, the influence of sympathovagal balance on neuromuscular performance in young athletes is not well assessed. The aim of this study was to assess the influence of the autonomic system on the performance of repeated sprints, involving predomina…

The “Journal of Functional Morphology and Kinesiology” Journal Club Series: Highlights on Recent Papers in Athletic Training

2018

We are glad to introduce the tenth Journal Club. This edition is focused on several relevant studies published in the last years in the field of athletic training, chosen by our Editorial Board members and their colleagues. We hope to stimulate your curiosity in this field and to share with you the passion for the sport seen also from the scientific point of view. The Editorial Board members wish you an inspiring lecture.

Effects of the Enriched Sports Activities-Program on Executive Functions in Italian Children.

2020

Physical activity (PA) during childhood plays an important role in brain development. This role is played in both the structural domain, prefrontal cortex area, and in the functional domain, involving the higher cognitive functions, including the executive functions (EF). Working memory (WM), inhibition, and switching as fundamental EF were investigated in an Italian children sample before and after four months of an Enriched Sports Activities-Program (ESA-Program). EFs were assessed at pre-test and post-test using, respectively, the digit span test, the color word Stroop test, and the trail making test derived from Millisecond Software. The Italian sample was composed of 141 children aged …

Relation between anaerobic power and rowing ergometer performance in young rowers

2013

Aims: Rowing performance over 2000m is dependent upon the functional capacity of both the aerobic and anaerobic energy pathways. Although several studies have indicated that maximal oxygen uptake is strongly related to rowing performance and it is the best predictor of performance in elite rowers, some evidence is that muscle power output could be an important predictor of performance. The aim of this study was to investigate the possible relationship between anaerobic power and rowing ergometer performance over 2000m in young rowers, and whether anaerobic power assessed could identify athletes with the best performance. Methods: We collected biometric characteristics and energy data, inclu…

Mean power during 20 sec all-out test to predict 2000-m rowing ergometer performance in national level young rowers

2014

Aim. The aim of this study was to assess the relationship between mean power during 20-s all-out rowing ergometer test and 2000-m rowing ergometer performance, in 20 young male rowers (mean age 15.2 ± 1.3 years). Methods. Mean power during 20-s all-out test (W20), maximal oxygen uptake during incremental test (VO2max), and anthropometric values, were measured and correlated with the time to perform a 2000-m trial (t2000). Results. W20 showed the highest correlation with t2000 (r = -0.947, P < 0.0001). Stepwise multiple linear regression analysis showed that W20, VO2max, and fat-free mass, were the variables most correlated with t2000, accounting for 95.1% of the variance, and that 89.7% …

Influences of baseline heart rate variability on repeated sprint performance in young soccer players

2015

AIM: The aim of this study was to assess the influence of the autonomic system on the performance of repeated sprints, involving predominantly neuromuscular power, in young soccer players. METHODS: Twelve young soccer players, selected for the Sicilian Regional Football Representative, mean age 15 years, were recruited. Baseline heart rate variability (HRV) was measured and indices of power spectral analysis (LF, HF, and ratio LF/HF) were calculated to evaluate the sympathovagal balance. The athletes performed 10 maximal 6--sec cycling sprints (RS), interspersed with 30--sec of recovery, to measure the peak power output (PP) represented by the highest power value recorded during a 6--sec sp…
