Effects of Combined Versus Multicomponent Training in Physically Active Women Aged 50-75 Years.

: This study aimed to compare the effects of combined training (CT) and multicomponent training (MT) on different health parameters in physically active women aged between 50 and 75 years. : The participants were randomly divided into two training groups (CT and MT), lasting 180 min per week, for 14 consecutive weeks of training with the level of physical activity, anthropometric measurements, blood pressure, strength, cardiorespiratory skills, coordination, flexibility, agility, and quality of life. : Participants who underwent CT and MT training showed positive responses regarding the assessment of body mass, waist circumference, lower limb resistance and strength, upper limb strength, and mental domain related to the quality of life.

Immune parameters, symptoms of upper respiratory tract infections, and training-load indicators in volleyball athletes.

Background: The control of immunological alterations becomes important during in-season training, as a result of increased incidence of infectious diseases, and may assist in avoiding interruptions to training due to illness.

Objective: The aim of the present study was to evaluate 28 weeks of chronic immune modulations in female volleyball athletes.

Methods: The sample was composed of twelve athletes aged 19.

Mechanotransduction pathways in skeletal muscle hypertrophy.

In the last decade, molecular biology has contributed to define some of the cellular events that trigger skeletal muscle hypertrophy. Recent evidence shows that insulin like growth factor 1/phosphatidyl inositol 3-kinase/protein kinase B (IGF-1/PI3K/Akt) signaling is not the main pathway towards load-induced skeletal muscle hypertrophy. During load-induced skeletal muscle hypertrophy process, activation of mTORC1 does not require classical growth factor signaling.
