PURPOSE The aim of this study was to compare asynchronous (ASY) arm cranking (cranks at 180° relative to each other) with synchronous (SYN) arm cranking (parallel crank setting) during the 30 s Wingate anaerobic test. METHODS Thirty two physically active men (aged 22.1 ± 2.4 y) completed two Wingate tests (one ASY and one SYN) separated by 4 d in a randomized counterbalanced order. The Wingat...

response to exercise training is different in variable age range, but it has not determined the differences physical response in children, adults and youth. according to this idea, the purpose of present study is a randomized trial to compare the effect of age on physical response in different periods to fitness training in various ages period. 36 participants voluntarily were randomized at thr...

Background Product specific research is necessary for determining the efficacy of dietary supplements comprised of different ingredients. Recently, the pre-workout supplement AssaultTM (MusclePharm, Denver, CO, USA) was investigated and demonstrated an ergogenic effect through improved lower body muscular endurance and agility choice reaction. However, continued product specific research is nec...

The purpose of this study was to identify off-ice variables that would correlate to on-ice skating sprint performance and cornering ability. Previous literature has not reported any off-ice testing variables that strongly correlate to on-ice cornering ability in ice hockey players. Thirty-six male hockey players aged 15-22 years (mean +/- SD: 16.3 +/- 1.7 years; weight = 70.8 +/- 10.4 kg; heigh...

Background. Regardless of the age, elite athletes exhibit various motor capabilities (e.g., speed; endurance; strength) that are specific to that particular sport. Objectives. The purpose of this study was to compare different aspects of physical fitness (agility, strength, endurance) in thirty, 9 year old elite soccer and hockey players. Methods. Participants completed a 90 minute familiariz...

The primary objective of this study was to assess the efficacy of measuring both aerobic and anaerobic power in a 60-second, maximal effort test. It was hypothesized that oxygen consumption increases rapidly during maximal effort and maximal oxygen consumption (VO2 max) may be reached in one minute. Fifteen United States Cycling Federation competitive cyclists performed the following tests: 1) ...

The aim of this study was to investigate the acute effect resistance band exercises on some performance parameters in young football players. Active and trained 16 male players (age: 15.18 ± .40 years; height: 170.81 7.21 cm; weight: 59.43 8.61 kg; body mass index (BMI): 20.26 1.60 kg/m2) voluntarily participated study. Subjects performed two different warmup protocols including jogging+dynamic...

The aim of the present study was to evaluate the influence of the Ramadan intermittent fast (RIF) on aerobic and anaerobic exercise performance in elite judo athletes (Judokas) maintaining their usual training loads. Physical performance tests (squat jump [SJ]), countermovement jump [CMJ], 30-second repeated jump, 30-m sprint, and the multistage fitness test) and fatigue scores were measured in...
