Exhausting stretch-shortening cycle (SSC) exercise causes greater impairment in SSC performance than in pure concentric performance
The purpose of the present study was to investigate the fatigue effect of repeated exhaustive stretch-shortening cycle (SSC) exercise on concentric muscle function. Ten healthy male subjects performed SSC exercise [92 (30) jumps] on a special sledge apparatus. Exhaustion occurred on average within 3...

| description | The purpose of the present study was to investigate the fatigue effect of repeated exhaustive stretch-shortening cycle (SSC) exercise on concentric muscle function. Ten healthy male subjects performed SSC exercise [92 (30) jumps] on a special sledge apparatus. Exhaustion occurred on average within 3 min. A squat jump (SJ) test utilizing a concentric-only action was performed immediately before and after the SSC exercise, and then 10 min, 20 min, 2 days and 4 days later. In addition, a drop jump (DJ) test using an SSC was also performed immediately before and 20 min after the SSC exercise, and 2 days and 4 days later. During jump tests, lower limb joint moment, power, and work contributions were analyzed by using the kinetic and kinematic data. The fatigue exercise was characterized by a relatively high blood lactate concentration [7.2 (0.8) mmol x l(-1)] and a 2-day delayed increase in serum creatine kinase activity [486 (300) U x l(-1)]. SJ performance decreased markedly immediately after the SSC exercise (P |

The surface electromyographic (EMG) activity of the lower limb muscles showed no obvious change in the SJ in comparison to the DJ, although in the latter there was a delayed decrease of knee extensor EMG during the pre-activation and braking phases. The results suggest that isolated concentric muscle function is affected mainly by acute metabolic fatigue after SSC exercise. During a follow-up period after the exercise, changes in hip and knee joint contribution in SJ showed a different recovery pattern compared to those in eccentric DJ. It could be suggested that exhaustive SSC exercise would mainly influence the relative power-work balance between the hip and knee joints during the eccentric phase of SSC. Thus different motor control strategies may account for the distinctive fatigue responses observed in SJ and DJ.</description><identifier>ISSN: 1439-6319</identifier><identifier>EISSN: 1439-6327</identifier><identifier>DOI: 10.1007/s00421-002-0716-z</identifier><identifier>PMID: 12560951</identifier><language>eng</language><publisher>Germany: Springer Nature B.V</publisher><subject>Adult ; Ankle - physiology ; Elasticity ; Electromyography - methods ; Exercise Test ; Hip - physiology ; Humans ; Knee - physiology ; Lactic Acid - blood ; Leg - physiology ; Male ; Movement - physiology ; Muscle Fatigue - physiology ; Muscle, Skeletal - physiology ; Physical Endurance - physiology ; Psychomotor Performance - physiology ; Stress, Mechanical ; Torque</subject><ispartof>European journal of applied physiology, 2003-02, Vol.88 (6), p.527-534</ispartof><rights>Springer-Verlag 2003</rights><lds50>peer_reviewed</lds50><woscitedreferencessubscribed>false</woscitedreferencessubscribed><citedby>FETCH-LOGICAL-c355t-7d761179962b2878c2cf4810909dd2d13ea9ac599d7683bf905feac553f0d0b53</citedby></display><links><openurl>$$Topenurl_article</openurl><openurlfulltext>$$Topenurlfull_article</openurlfulltext><thumbnail>$$Tsyndetics_thumb_exl</thumbnail><link.rule.ids>310,311,315,781,785,790,791,23935,23936,25145,27929,27930</link.rule.ids><backlink>$$Uhttps://www.ncbi.nlm.nih.gov/pubmed/12560951$$D View this record in MEDLINE/PubMed$$Hfree_for_read</backlink></links><search><creatorcontrib>Horita, T</creatorcontrib><creatorcontrib>Komi, P V</creatorcontrib><creatorcontrib>Hämäläinen, I</creatorcontrib><creatorcontrib>Avela, J</creatorcontrib><title>Exhausting stretch-shortening cycle (SSC) exercise causes greater impairment in SSC performance than in pure concentric performance</title><title>European journal of applied physiology</title><addtitle>Eur J Appl Physiol</addtitle><description>The purpose of the present study was to investigate the fatigue effect of repeated exhaustive stretch-shortening cycle (SSC) exercise on concentric muscle function.
