Genotypic Variations Associated with Changes in Body Mass in Response to Endurance Training.

This study investigates the extent to which different genotypes can explain changes in body mass following an 8-week running program, in a UK population. Participants were randomly assigned to either a training ( = 17) or control group ( = 21). Participants' diets were not altered, only the exercise regime was manipulated to isolate effects.

Responsiveness to endurance training can be partly explained by the number of favorable single nucleotide polymorphisms an individual possesses.

Cardiorespiratory fitness is a key component of health-related fitness. It is a necessary focus of improvement, especially for those that have poor fitness and are classed as untrained. However, much research has shown individuals respond differentially to identical training programs, suggesting the involvement of a genetic component in individual exercise responses.

Do exercise-associated genes explain phenotypic variance in the three components of fitness? a systematic review & meta-analysis.

The aim of this systematic review and meta-analysis was to identify a list of common, candidate genes associated with the three components of fitness, specifically cardiovascular fitness, muscular strength, and anaerobic power, and how these genes are associated with exercise response phenotype variability, in previously untrained participants. A total of 3,969 potentially relevant papers were identified and processed for inclusion. After eligibility and study selection assessment, 24 studies were selected for meta-analysis, comprising a total of 3,012 participants (male n = 1,512; females n = 1,239; not stated n = 261; age 28 ± 9 years).

The plateau at V˙ O is associated with anaerobic alleles.

Objectives: This study tests the hypothesis that individuals who achieve a plateau at V˙ O (V˙ O) are more likely to possess alleles, associated with anaerobic capacity, than those who do not.

Design: A literature survey, physiological testing and genetic analysis was used to determine any association between the aerobic and anaerobic polymorphisms of 40 genes and V˙ O.

Methods: 34, healthy, Caucasian volunteers, completed an exercise test to determine V˙ O and  V˙ O.

A novel phototropic response to supplementary ultraviolet (UV-B and UV-A) radiation in the siliquas of oilseed rape (Brassica napus L.) grown under natural conditions.

An outdoor polychromatic response spectrum for the phototropic curvature of the seed pods (siliquas) of oilseed rape (Brassica napus L. cv. Rebel) has been measured.
