  1. doi request reprint The two asymmetries of the bouncing step
    Giovanni A Cavagna
    Dipartimento di Fisiologia Umana, Universita degli Studi di Milano, Milan, Italy
    Eur J Appl Physiol 107:739-42. 2009
    ..The increase of the push on the ground with increasing running speed improves the "elastic" rebound of the body by privileging the role of tendons relative to muscle within muscle-tendon units...
  2. pmc The role of gravity in human walking: pendular energy exchange, external work and optimal speed
    G A Cavagna
    Istituto di Fisiologia Umana, Universita degli Studi di Milano, 20133 Milan, Italy
    J Physiol 528:657-68. 2000
    ..In conclusion, over the range studied, gravity increases the work required to walk, but it also increases the range of walking speeds...
  3. doi request reprint An analysis of the rebound of the body in backward human running
    G A Cavagna
    Dipartimento di Fisiologia Umana, Universita, degli Studi di Milano, 20133 Milan, Italy
    J Exp Biol 215:75-84. 2012
    ..We suggest that the catapult-like mechanism of backward running, although requiring greater energy expenditure and not providing a smoother ride, may allow a safer stretch-shorten cycle of muscle-tendon units...
  4. pmc Running backwards: soft landing-hard takeoff, a less efficient rebound
    G A Cavagna
    Dipartimento di Fisiologia Umana, Universita degli Studi di Milano, Via Mangiagalli 32, Milan 20133, Italy
    Proc Biol Sci 278:339-46. 2011
    ..More metabolic energy must be spent in the opposite case when muscle is forced to work against its basic property (i.e. when it must exert a greater force during shortening and a lower force during stretching)...
  5. pmc The bounce of the body in hopping, running and trotting: different machines with the same motor
    G A Cavagna
    Dipartimento di Fisiologia Umana, Universita degli Studi di Milano, 20133 Milan, Italy
    Proc Biol Sci 276:4279-85. 2009
    ..We suggest that the landing-takeoff asymmetry is an index of a lack of elasticity, which increases with increasing the role of muscle relative to that of tendon within muscle-tendon units...

    G A Cavagna
    Istituto di Fisiologia Umana, Universita degli Studi di Milano, Via Mangiagalli, 32, 20133 Milan, Italy
    J Exp Biol 209:4051-60. 2006
    ..Above this speed, the two durations (<0.1 s) are similar, suggesting that the length change is almost totally due to stretch-recoil of the tendons with nearly isometrically contracting fibres...

    G A Cavagna

    Istituto di Fisiologia Umana, Universita degli Studi di Milano, Italy
    J Exp Biol 205:3413-22. 2002
    ..It was found that loading improves the transduction of E(p) to E(k) during the descent of the centre of mass. The improvement is not significant in European subjects, whereas it is highly significant in African women...
