INTRODUCTION Motor commands to perform exercise tasks may also induce activation of cardiovascular centres to supply the energy needs of the contracting muscles. Mental stressors per se may also influence cardiovascular homeostasis. We investigated the cardiovascular response of trained runners simultaneously engaged in mental and physical tasks to(More)

We present a generalized QCD factorization scheme for the high energy inclusive polarized process, (A, SA) + (B, SB) → C + X, including all intrinsic partonic motions. This introduces many non-trivial azimuthal phases and several new spin and k⊥ dependent soft functions. The formal expressions for single and double spin asymmetries are discussed. Numerical(More)
We present a calculation of single and double spin asymmetries for inclusive hadron production in hadronic collisions. Our approach is based on Leading Order (LO) perturbative QCD and generalized factorization theorems, with full account of intrinsic parton momentum, k⊥, effects. This leads to a new class of spin and k⊥dependent distribution and(More)
The purpose of the present investigation was to study the metabolic demand and cardiovascular response during a typical horse riding session. To this aim, 19 (9 male, 10 female) riders, regularly participating in competitions, were enrolled. They underwent a preliminary, incremental exercise test on a cycle-ergometer to assess their anaerobic threshold (AT)(More)
We summarize the present phenomenology of Sivers and Collins effects for transverse single spin asymmetries in polarized proton–proton collisions within the framework of the generalized parton model (GPM). We will discuss a re-assessment of the Collins effect and some preliminary predictions for SSA's in p ↑ p → π, K + X processes at RHIC obtained using(More)
We study the transverse single spin asymmetry (SSA), AN , for the single inclusive process ℓp ↑ → h + X, in a perturbative QCD factorization scheme with inclusion of spin and transverse momentum dependent (TMD) distributions. By adopting the relevant TMDs (Sivers and Collins functions) as extracted from semi-inclusive deep inelastic scattering (SIDIS) and e(More)
