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.

Effects of concurrent training on interleukin-6, tumour necrosis factor-alpha and C-reactive protein in middle-aged men.

The purpose of this study was to evaluate the effects of moderate- to high-intensity resistance and concurrent training on inflammatory biomarkers and functional capacity in sedentary middle-aged healthy men. Participants were selected on a random basis for resistance training (n = 12), concurrent training (n = 11) and a control group (n = 13). They performed three weekly sessions for 16 weeks (resistance training: 10 exercises with 3 × 8-10 repetition maximum; concurrent training: 6 exercises with 3 × 8-10 repetition maximum, followed by 30 minutes of walking or running at 55-85% [Vdot]O(2peak)).

Effect of oat bran on time to exhaustion, glycogen content and serum cytokine profile following exhaustive exercise.

The aim of this study was to evaluate the effect of oat bran supplementation on time to exhaustion, glycogen stores and cytokines in rats submitted to training. The animals were divided into 3 groups: sedentary control group (C), an exercise group that received a control chow (EX) and an exercise group that received a chow supplemented with oat bran (EX-O). Exercised groups were submitted to an eight weeks swimming training protocol.

Effects of resistance training on resistin, leptin, cytokines, and muscle force in elderly post-menopausal women.

It may be that resistance exercise can be used to prevent the degenerative processes and inflammation associated with ageing. Thus, the aim of the present study was to evaluate the effects of resistance training on cytokines, leptin, resistin, and muscle strength in post-menopausal women. Thirty-five sedentary women (mean age 63.

Comparison between linear and daily undulating periodized resistance training to increase strength.

To determine the most effective periodization model for strength and hypertrophy is an important step for strength and conditioning professionals. The aim of this study was to compare the effects of linear (LP) and daily undulating periodized (DUP) resistance training on body composition and maximal strength levels. Forty men aged 21.

Comparison of linear and reverse linear periodization effects on maximal strength and body composition.

There are few studies that have compared different periodization methods for strength and hypertrophy. The aim of this study was to verify the effect of a 12-week strength training program with different periodization models on body composition and strength levels in women ranging from 20 to 35 years of age. Participants had a minimum of 6 months of experience in strength training, and they were divided into two groups: linear periodization (LP, n = 10) and reverse linear periodization (RLP, n = 10).

Exercise Induced Alterations in Rat Monocyte Number, Morphology, and Function.

The purpose of this study was to verify the histophysiological alterations in monocytes and macrophages induced by short periods of exercise. Male Wistar rats (age = 2 months, body weight = 200g) were divided into seven groups (N = 6 each): sedentary control (C), groups exercised (swimming) at low intensity for 5 (5L), 10 (10L), and 15 minutes (15L), and groups exercised at moderate intensity for 5 (5M), 10 (10M) or 15 minutes (15M). At moderate intensity the animals carried a load of 5% of body weight on their backs.
