Abstract: INTRODUCTION: Cycling has been the subject of numerous studies. Among these, measuring muscular performance during cycling has attracted much interest. OBJECTIVE: To investigate the relationship between Wattbike ® and isokinetic findings in a group of cyclists. METHODS: Thirty-seven male cyclists performed a 30-s anaerobic power test on a Wattbike ® and then were tested concentrically for knee extensor and flexor strength using isokinetic dynamometry. RESULTS: There was a positive fair-to-moderate correlation between the peak moment, peak power, and total work derived from …the Wattbike ® and the respective parameters evaluated isokinetically. CONCLUSION: While the findings exclude interchangeability of the two methods, the fact that total work is the most closely associated parameter among the measurements highlights its importance as an outcome measure in muscle performance in cyclists.

Abstract: BACKGROUND: Small-sided games are a popular training method that have shown its effectiveness in improving athletic performance in football players. OBJECTIVE: To compare the acute physiological and neuromuscular responses and time-motion characteristics during small-sided games played with and without wildcard players. METHODS: Sixteen amateur male football players completed two small-sided games protocol: 4-a-side and 4-a-side with wildcard players. Time-motion characteristics during games, muscular performance parameters before and after small-sided games protocols, physiological response in terms of heart rate and muscle oximetry and rate of perceived exertion were collected. RESULTS: Both …small-sided games formats induced changes in sprint performance (before-after comparison), in the rate of perceived exertion, heart rate-related variables and time-motion parameters (p < 0.05). In a comparison between small-sided games formats, lower values of oxygen saturation, heart rate, rate of perceived exertion and time-motion parameters (p < 0.05) were reported during small-sided games with wildcard players in both working and recovery periods. CONCLUSIONS: The inclusion of wildcard players during small-sided games cause a reduction in perceptual, physiological demands and time-motion parameters when compared to control condition.
