Acute Effect of High-Intensity Aerobic Exercise Performed on Treadmill and Cycle Ergometer on Strength Performance

Abstract

Concurrent training (i.e., combination of endurance with strength training) may result in negative interference on strength performance. Moreover, there are indications that the magnitude of this interference is dependent on endurance exercise mode. Thus, this study aimed to verify the acute effects of previous running and cycling on strength endurance performance. After the determination of the maximum intensity reached (Imax) during treadmill running and cycle ergometer pedaling and half-squat maximum strength (1 repetition maximum [1RM]), 10 physically active men were submitted to 3 experimental conditions: control condition (S) comprised of 4 sets of maximum repetitions at 80% 1RM, intermittent running (RS), and cycling (CS) conditions (15 × 1 minute:1 minute in the Imax) followed by the strength exercise (S). Maximum number of repetitions (MNR), total session volume (TV), and vastus lateralis electromyographic signal (VLRMS) were analyzed. It was observed that MNR and TV performed in set 1 in the S condition was superior to that performed in set 1 in the RS (p < 0.001) and CS (p < 0.001) conditions; and set 2 in the S condition was superior to set 2 only in the CS for the MNR (p = 0.032) and TV (p = 0.012). For the VLRMS, there was a main effect for repetition, with higher values in the last repetition compared with the second one (p < 0.01). In conclusion, an aerobic exercise bout before strength exercise impairs the subsequent strength endurance performance. In addition, the magnitude of the interference effect was higher after the aerobic cycling exercise.

High-Intensity Intermittent Exercise and its Effects on Heart Rate Variability and Subsequent Strength Performance

“…The subjects performed an incremental treadmill test to volitional exhaustion (Panissa et al, 2015 ). The initial speed was set at 8 km·h −1 .…”

“…Each set was separated by a 2-min interval. The maximum number of repetitions (MNR) were computed and the total weight lifted (TWL) was also calculated as follows: TWL = MNR × weight lifted (De Souza et al, 2007 ; Panissa et al, 2012 , 2015 ).…”

A Brief Review on Concurrent Training: From Laboratory to the Field

“…It seems that low volume, maximum and supramaximal HIIT/SIT [≥85% of VO 2max velocity (vVO 2max ) or peak power (W peak )] endurance training, during CT, did not result in decrements of strength, power and muscle hypertrophy adaptations, and in many cases they induce greater resistance training adaptations, while significantly increasing endurance capacity and performance, compared with high-volume low-moderate intensity endurance training [3,8,12,13,14,15,16,17,18,19,20,21,22,23,24,25,26,28,45,61,67,68,69,70,71,72,73,74,75,76,77,78]. In addition, as described above, at the molecular level it seems that when cycling is used, compared with running, there are even lower or no negative results on resistance exercise-induced adaptations, especially on strength and power performances [8,18,28,72,73,79,80,81], indicating that cycling is superior to running [82]. Thus, according to the existing literature, inclusion of high intensity (maximal or supramaximal; ≥100% of vVO 2max or W peak ), low-volume (<20 min) HIIT and SIT endurance training seems to minimize the negative CTE, especially when cycling is preferred instead of running.…”

“…The same controversial results are observed in training studies. Many studies report that when endurance training is performed prior to resistance, muscle hypertrophy, strength and power performances adaptations are compromised [14,46,70,74,79,80,81,85,86,87,88,89,90,91]. Probably, by performing endurance exercises prior to resistance training, an inhibition of performance during resistance training is observed, which may lead to compromised acute molecular responses, and thus to lower resistance training-induced adaptations [14,46,74,85,86,87,88,89,92].…”

Efeito agudo do exercício aeróbio com diferentes volumes no desempenho de força em indivíduos fisicamente ativos

“…isoinercial ou isocinético) (LEVERITT; ABERNETHY, 1999;MACLAUGHLIN;ABERNETHY, 2000) e o modo do exercício aeróbio (i.e. corrida ou pedalada) (PANISSA et al, 2015). No entanto, a magnitude da interferência no TC pode ser dependente também do volume do exercício aeróbio realizado.…”
