  1. 1. The Acute Metabolic Response of Intermittent Hypoxic Resistance Exercise : A Cross-Over RCT

    Master-uppsats, Gymnastik- och idrottshögskolan, GIH/Institutionen för idrotts- och hälsovetenskap

    Författare :Jonas Falgin Hultgren; [2019]
    Nyckelord :Intermittent Resistaypoxic resistance exercise; lactate accumulation; cross-over RCT; RCT; Random Controlled Trial; healthy; men; blood; plasma; styrketräning; hypoxi; normoxi; saturation; laktat; ansamling; ph; blod; plasma; tung styrketräning; metabolisk; respons; randomiserad; kontrollerad; experiment; friska; unga; män; skelettmuskulatur;

    Sammanfattning : Aim The aim for this present study was to investigate the acute metabolic response from intermittent resistance exercise during hypoxia, with the following research questions: (1) Are blood levels of lactate and glucose different between hypoxia and normoxia? (2) Does hypoxia induce higher lactate accumulation and pH reduction in the human skeletal muscle? (3) Is there a relationship between plasma-, blood- and muscle lactate? Method Eight healthy males (30 ± 2 years) performed 6 sets of unilateral leg extension on each leg (75% of 1RM) with randomized normoxic (20,9% inspired 𝑂2) and normobaric hypoxic (12% inspired 𝑂2) conditions. A total of 5 muscle biopsies was extracted from m. LÄS MER

  2. 2. Kan aktiv höftadduktion i kombination med instabilt underlag bidra till ökad muskelaktivering av vastus medialis oblique vid knäböj : Pilotstudie

    Uppsats för yrkesexamina på grundnivå, Luleå tekniska universitet/Institutionen för hälsovetenskap; Luleå tekniska universitet/Institutionen för hälsovetenskap

    Författare :Alexander Avernäs; Marcus Magnusson; [2019]
    Nyckelord :Elektromyografi; knäböj; vastus lateralis; vastus medialis oblique.;

    Sammanfattning : Bakgrund: Vastus medialis kan delas in i två olika komponenter beroende på fiberriktning. Den nedre delen vastus medialis oblique (VMO) har sitt ursprung från adductor magnus och drar patella medialt medans vastus lateralis (VL) drar patella lateralt. LÄS MER

  3. 3. Physiological characteristics of sodium lactate infusion during resistance exercise

    Master-uppsats, Gymnastik- och idrottshögskolan, GIH/Institutionen för idrotts- och hälsovetenskap

    Författare :Sebastian Danielsson; [2019]
    Nyckelord :sodium lactate; sodium lactate infusion; infusion; resistance exercise; knee-extensor; vastus lateralis; metabolic effects; hematological effects; plasma lactate; muscle lactate; muscle content of lactate; MHC; fiber type; blood pH; muscle pH; blood lactate; blood sodium; blood potassium; blood glucose; hemoglobin; in vivo; randomized; cross-over;

    Sammanfattning : Previous studies that utilized sodium lactate infusion did not use resistance exercise protocol or analyzed muscle biopsies, or performed sex specific analysis. Aim: We initiated a project where resistance exercise was performed with low and high levels of lactate, acquired by venous lactate infusion where the specific aim of this study was to investigate and chart the physiological characteristics of sodium lactate infusion during a bout of resistance exercise on whole group level and sexes separated Method: A randomized, placebo controlled, cross-over design was implemented where male (n = 8) and female (n = 8) subjects accustomed to resistance exercise visited the laboratory three times for preliminary testing and training familiarization.

  4. 4. Do different levels of lactate have an impact on mTORC1-signal and protein synthesis induced by resistance exercise?

    Master-uppsats, Gymnastik- och idrottshögskolan, GIH/Institutionen för idrotts- och hälsovetenskap

    Författare :Rasmus Liegnell; [2018]
    Nyckelord :mtorc1; lactate; hypertrophy; muscle cell; resistance exercise;

    Sammanfattning : Aim: To investigate the role of lactate as a potential signaling molecule, for the molecular mechanisms underlying acute resistance exercise adaptation in the muscle cell.    Method: Four women and four men recruited to perform two trials of unilateral leg extension exercise performed with either an infusion of sodium lactate or isotonic saline (placebo), in a randomized, blinded, crossover fashion.

  5. 5. Muskelaktiveringsmönster i quadriceps i relation till dynamisk valgus vid ett drop-landingtest. : – En studie gjord på kvinnliga fotbollsspelare

    Kandidat-uppsats, Umeå universitet/Idrottsmedicin

    Författare :Lilja Öhman; [2018]
    Nyckelord :ACL injury; EMG; soccer; dynamic valgus; Korsbandsskada; ACL; EMG; fotboll; dynamisk valgus;

    Sammanfattning : Både biomekaniska och neuromuskulära faktorer hos kvinnliga fotbollsspelare har visat sig påverka risken att drabbas av främre korsbandsskador. Obalanserad muskelaktivering kring knäleden har visat sig påverka ledstabiliteten. LÄS MER
