The effects of exercise on VOpeak, quality of life and hospitalization in heart failure patients: A systematic review with meta-analyses.

Exercise training has become one of the most fundamental components of cardiac rehabilitation. This systematic review with meta-analyses has the objective to determine the effectiveness of exercise on selected cardiac rehabilitation outcomes, i.e.

The effect of four weeks of plyometric training on reactive strength index and leg stiffness is sport dependent.

Background: Plyometric exercises are often used to develop lower limb strength and performance-related biomechanics such as leg stiffness. However, the effectiveness of plyometric training may depend on participants' own training and performance demands. The purpose of this study was to examine the effect of plyometric training on Reactive Strength Index (RSI) and leg stiffness (Kleg) on young athletes of different sports.

Effect of acupuncture in physiological parameters and endurance running performance.

Background: Few studies have examined the effect of acupuncture (AC) treatment in aerobic capacity and endurance performance in healthy adults. Thus, the aim of the present study was to evaluate the effects of AC on selected physiological parameters and 3 km running performance.

Methods: Twenty-four healthy subjects with low to moderate aerobic capacity participated in the study and randomly assigned in two groups: AC group (ACG - N.

The influence of a hurdle target point on the kinematics of the handspring vault approach run during training.

The aim of this study was to investigate if a visible target for the hurdle take-off would influence the onset of visual regulation and hurdle kinematics during the approach run. Ten elite male gymnasts (age 23.4 ± 4.

Short-term effect of whole-body vibration training on balance, flexibility and lower limb explosive strength in elite rhythmic gymnasts.

The purpose of this study was to examine whether whole-body vibration (WBV) training results in short-term performance improvements in flexibility, strength and balance tests in comparison to an equivalent exercise program performed without vibration. Eleven elite rhythmic gymnasts completed a WBV trial, and a control, resistance training trial without vibration (NWBV). The vibration trial consisted of eccentric and concentric squatting exercises on a vibration platform that was turned on, whereas the NWBV involved the same training protocol with the platform turned off.

Competitive state anxiety and performance in young female rhythmic gymnasts.

The study was designed to examine the competitive state anxiety and self-confidence of rhythmic gymnasts participating in the Greek national competition. 86 participants, ages 11 and 12 years, completed the Competitive State Anxiety Inventory-2, 1 hr. before competition.

Influence of angle of view on judges' evaluations of inverted cross in men's rings.

The present study focuses on two factors that may influence the accuracy and precision of a judge's evaluation of the angular deviation error in "inverted cross" (angle of the arms away from the horizontal axis). 16 Greek judges of competitive gymnastics participated in an evaluation of the magnitude of the error in the skill. Photographs of the performance of 8 gymnasts were shown to the judges in triplicates in random order from three angles of observation (0 degrees, 45 degrees, and 90 degrees) on a computer screen.
