The rating of perceived exertion predicts intermittent vertical jump demand and performance

Abstract

The aims of this study were (a) to assess the ability of the rating of perceived exertion (RPE) to predict performance (i.e. number of vertical jumps performed to a fixed jump height) of an intermittent vertical jump exercise, and (b) to determine the ability of RPE to describe the physiological demand of such exercise. Eight healthy men performed intermittent vertical jumps with rest periods of 4, 5, and 6 s until fatigue. Heart rate and RPE were recorded every five jumps throughout the sessions. The number of vertical jumps performed was also recorded. Random coefficient growth curve analysis identified relationships between the number of vertical jumps and both RPE and heart rate for which there were similar slopes. In addition, there were no differences between individual slopes and the mean slope for either RPE or heart rate. Moreover, RPE and number of jumps were highly correlated throughout all sessions (r = 0.97-0.99; P < 0.001), as were RPE and heart rate (r = 0.93-0.97; P < 0.001). The findings suggest that RPE can both predict the performance of intermittent vertical jump exercise and describe the physiological demands of such exercise.

Influência Dos Saltos Verticais Na Percepção Da Carga Interna De Treinamento No Voleibol

“…Por outro lado, Pereira et al 17 analisaram a relação do número de saltos verticais realizados em um teste de resistência de saltos com diferentes intervalos de recuperação e sua influência nos valores apontados de PSE com praticantes de voleibol e basquetebol. Diferente dos resultados encontrados em nosso estudo, altas correlações foram encontradas entre os números de saltos realizados e os valores de PSE (r = 0,97 -0,99) em todas as baterias de testes com diferentes intervalos entre os saltos (4s, 5s, 6s).…”

Relationship between Anaerobic Parameters Provided from MAOD and Critical Power Model in Specific Table Tennis Test

“…In addition, the supramaximal exercise intensity used to estimate the MAOD was rigorously performed until exhaustion, corresponding to the maximal eff ort in table tennis condition. In a recent study Pereira et al [ 42 ] described that maximal eff ort (rating of perceived exertion of ≈ 20) and exhaustion can both be achieved with low blood lactate values ( ≈ 4 mmol.L − 1 ), similar to what was found in the present study. Regarding size sample, increasing the sample size could result in signifi cant correlation coeffi cients between W′s and MAOD, but would not result in stronger correlation coeffi cients, which were very weak ( r = 0.06-0.21).…”

Influence of Carrying Loads on Ratings of Perceived Exertion and Heart Rate during Walking

“…Moreover, the increase in RPE during the treadmill walking can be explained by increments in perceived pulmonary efforts that are attributable to progressive hyperventilation. Indeed, leg effort should be near maximal from the very beginning of the exercise bout; conversely, ventilation would increase because of progressive metabolic acidosis and contribute markedly to RPE measures as the load was increased during the walking [29]. In addition, RPE has been correlated with several physiological indicators of exercise intensity such as oxygen consumption, blood lactate concentration, and HR during a variety of exercise protocols [30].…”
