EFFECT OF THE INTRODUCTION OF PAUSES BETWEEN REPETITIONS IN THE CAPACITY TO SUSTAIN MAXIMAL MAGNITUDES OF PEAK VELOCITY DURING BENCH PRESS
Background An important number of sport modalities sustain its performance in the capacity to repeat efficiently a sport movement without fatigue. However, it is a fact that this mechanism will appear and affect the athletes9 velocity magnitudes. The aim of this study was to compare the Peak Velocity (PV) in two protocols: Traditional Training (TT) vs. 20 s inter-repetition rest (IRR) with the Optimal Load (OL) for the maximal Power output (OL: 50.7±8.0% of 1-RM). Methods Fifteen male, physical education students, participated in this study (age: 23.1±1.6 years; height: 177.1±7.7 cm; mass: 76.2±9.2 kg; 1-RM: 93.8±14.3 kg; 1-RM/mass: 1.24±0.21). After the validation of the bench press 1-RM a…
Effect of the pacing strategy during half-duration resistance test on the mechanic, metabolic and cardio-respiratory response
Objective: Changes in pacing rhythm are translated into functional and metabolic changes that can be significantly reflected in the final results of an athlete. Method: Ten male subjects, with moderate performance level (age: 25.2 ± 2.2 years; VO2max: 56.9 ± 5.7 ml kgâ1 minâ1), performed four 5-min races with different pacing strategies: constant-pace (CP), record-pace (RP), kicker-pace (KP), incremental-pace (IP). Results: The cardio-respiratory response did not show statistically significant. There were statistically significant differences (p â¤Â 0.05) in the energetic efficiency among the protocols CP vs. RP, CP vs. KP and RP vs. IP. When results were analyzed by partials (1-m…
EFFECT OF THE INTER-REPETITION REST LENGTH IN THE CAPACITY TO REPEAT PEAK POWER OUTPUT
Background High volumes of work affect the movement technical quality, reducing the muscular capacity to develop high magnitudes of force. One of the most important parameters that we can use to regulate the training loads are the inter-repetition rests (IRR). The purpose of this study was to compare the Peak Power output (PP) magnitudes in three different inter-repetition length sets with Optimal Load (OL) in Bench Press (BP). Methods Our sample was formed by 16 male physical education students (age: 23.6±2.1 years; height: 178.2±6.9 cm; mass: 78.3±7.2 kg; 1RM: 90.2±13.9 kg; 1RM/mass: 1.15±0.16), who performed the BP test with different IRR with OL (48.8±7.2% of 1RM; 44.2±11.5 kg). After e…
Respostas mecânicas da musculatura do joelho de bodyboarders de alto nível durante o desempenho
INTRODUCTION: bodyboarding is a kind of surfing that has been growing very rapidly over the last decade and has now developed into one of the fastest growing water sports in the world.OBJECTIVES: evaluate the effects of fatigue on rectus femoris RF, vastus lateralis VL and vastus medialis VM and biceps femoris BF and semitendinosus ST during a high-level bodyboard competition using tensiomyography TMG.METHODS: subjects were 11 highly experienced years of practice: 15, SD=4.65 male bodyboarders age: 28.17, SD=2.89, body weight: 74.83, SD=6.13kg; height: 179.25, SD=3.93cm; BMI: 23.29, SD=1.81 participating in the final of the 2010 Spanish championship.RESULTS: the fatigue is especially eviden…
