“…These results confirmed the findings of the previous studies reporting that muscle damage was less for KE compared with EF Saka et al 2009), and muscle damage was greater for KF than KE (Franklin et al 1993). New findings were that muscle damage was similar between EF and EE, the arms muscles (EF and EE) were more susceptible to muscle damage than KF, and the magnitude of muscle damage was different among the muscles even within the same individuals.…”

“…It is possible that a difference in the frequency of eccentric contractions in daily activities, a difference in muscle length changes during the eccentric contractions in the exercise protocol of the present study, and a difference in muscle architecture explain the difference in the muscle damage. It is possible that KE is exposed to even more eccentric contractions than KF in daily activities as proposed by Franklin et al (1993). Regarding the muscle length, the muscles were not fully extended in the KE exercise (30°-120°), but extended to the end of ROM in the KF exercise (90°-0°) in the present study (Fig.…”

“…Only one previous study (Franklin et al 1993) compared KE and KF for their responses to eccentric exercise, but the muscle damage markers were limited to plasma CK activity and muscle soreness. They reported that the increases in plasma CK activity and muscle soreness following 3 sets of 35 isokinetic (120°s -1 ) eccentric contractions were significantly greater for the KF compared with the KE.…”

“…In the present study, the same number of maximal eccentric contractions (i.e., 30 contractions) was set for the four exercises, although previous studies (Crameri et al 2007;Dudley et al 1997;Golden and Dudley 1992;Franklin et al 1993) used a larger number of eccentric contractions especially for the KE (e.g. 70-210 contractions) or KF (e.g.…”

“…To the best of our knowledge, only one study compared two leg muscle groups. Franklin et al (1993) examined the KE and knee flexors (KF) for changes in plasma CK activity and muscle soreness following 3 sets of 35 maximal isokinetic (120°s -1 ) eccentric contractions. They reported that increases in plasma CK activity and muscle soreness were significantly greater for the KF compared with the KE.…”

This study tested the hypothesis that changes in indirect markers of muscle damage following maximal eccentric exercise would be smaller for the knee extensors (KE) and flexors (KF) compared with the elbow flexors (EF) and extensors (EE). A total of 17 sedentary men performed five sets of six maximal isokinetic (90° s(-1)) eccentric contractions of EF (range of motion, ROM: 90°-0°, 0 = full extension), EE (55°-145°), KF (90°-0°), and KE (30°-120°) using a different limb with a 4-5-week interval in a counterbalanced order. Changes in maximal isometric and concentric isokinetic strength, optimum angle, limb circumference, ROM, plasma creatine kinase activity and myoglobin concentration, muscle soreness, and echo-intensity of B-mode ultrasound images before and for 5 days following exercise were compared amongst the four exercises using two-way repeated-measures ANOVA. All variables changed significantly following EF, EE, and KF exercises, but KE exercise did not change the optimum angle, limb circumference, and echo-intensity. Compared with KF and KE, EF and EE showed significantly greater changes in all variables, without significant differences between EF and EE. Changes in all variables were significantly greater for KF than KE. For the same subjects, the magnitude of change in the dependent variables following exercise varied among the exercises. These results suggest that the two arm muscles are equally more susceptible to muscle damage than leg muscles, but KF is more susceptible to muscle damage than KE. The difference in the susceptibility to muscle damage seems to be associated with the use of muscles in daily activities.

Influence of Acute Eccentric Exercise on the H:Q Ratio

et al. 2011

View full text Add to dashboard Cite

The purpose of the present study was to examine the effects of an acute bout of eccentric exercise on maximal isokinetic concentric peak torque (PT) of the leg flexors and extensors and the hamstrings-to-quadriceps (H:Q) strength ratio. Sixteen male (mean±SD: age=20.9±2 years; stature=177.0±4.4 cm; mass=76.8±10.0 kg) volunteers performed maximal, concentric isokinetic leg extension and flexion muscle actions at 60°·sec - 1 before and after (24-72 h) a bout of eccentric exercise. The eccentric exercise protocol consisted of 4 sets of 10 repetitions for the leg press, leg extension, and leg curl exercises at 120% of the concentric one repetition maximum (1-RM). The results indicated that the acute eccentric exercise protocol resulted in a significant (P<0.05) decrease in isokinetic leg flexion (13-19%) and leg extension (11-16%) PT 24-72 h post-exercise. However, the H:Q ratios were unaltered by the eccentric exercise protocol. These findings suggest that an acute bout of eccentric exercise utilizing both multi - and single - joint dynamic constant external resistance (DCER) exercises results in similar decreases in maximal isokinetic strength of the leg flexors and extensors, but does not alter the H:Q ratio.
