• Muscle mechanics during human movement revealed by in vivo measurements of tendon force and muscle length 

  Finni, Taija (Jyväskylän yliopisto, 2001)

  Yleensä lihasten toimintaa ihmisen liikkumisessa on tutkittu luonnollisissa liikkumistilanteissa vain mallintamisen keinoin, koska lihaspituuksien ja voimien suora mittaaminen on ollut joko teknisten tai eettisten syiden ...

• Hill’s Equation in Arm Push of Shot Put and in Braking of Arm Rotation 

  Rahikainen, Ahti; Virmavirta, Mikko (Book Publisher International, 2019)

  This chapter consists of the earlier study of shot put where A.V. Hill’s force-velocity relationship was transformed into a constant maximum power model consisting of three different components of power. In addition, the ...

• Modeling the force – velocity relationship in arm movement 

  Rahikainen, Ahti; Avela, Janne; Virmavirta, Mikko (Scientific Research Publishing SCIRP, 2012)

  Modeling the force-velocity dependence of a muscle-tendon unit has been one of the most interesting objectives in the field of muscle mechanics. The so-called Hill’s equation [1,2] is widely used to describe the force-velocity ...

• Effect of External Work Magnitude on Mechanical Efficiency of Sledge Jumping 

  Seki, Keitaro; Kyröläinen, Heikki (Human Kinetics Publishers, 2024)

  The mechanical efficiency of human locomotion has been studied extensively. The mechanical efficiency of the whole body occasionally exceeds muscle efficiency during bouncing type gaits. It is thought to occur due to ...

• Motor unit activation and force production during eccentric, concentric and isometric actions 

  Linnamo, Vesa (Jyväskylän yliopisto, 2002)

  The aim of the present series of studies is to examine force and myoelectrical activity in human forearm flexors and knee extensors during dynamic and isometric muscle actions. The main purposes are 1) to clarify the ...
