According to Mohantyet al.(2012) height is a fundamental unit used in
assessing an individual’s growth and nutrition as well as calculating
their body surface. It constitutes an essential element in the
description of the human population. Average difference height is
relevant to the measurement of the health and wellness (standard of
living and quality of life) of populations (Bolton-Smith, 2000; Ali et
al., 2000; Mohantyet al., 2001).
In every human, the heart rate
reflects the speed of the heartbeat measured by the number of
contractions of the heart per unit of time that is, beats per minutes
(BPM). This heart rate can vary considerably depending on the body's
physical needs, including the need to absorb oxygen and excrete carbon
dioxide. Activities that can provoke change include; physical
activities, sleep, anxiety, stress, illness, ingesting, and drugs.
Marked changes in heart rate (HR) reaction occur during physical
exercise and during physical training interventions among different sex
of individuals. The changes in HR are primarily due to alterations in
autonomic tone: parasympathetic tone slows down the HR, and sympathetic
stimulation increases it (Tapanainenet al. 2002).
The regular
practice of physical exercises is an important factor to reduce
morbidity and mortality rates of cardiovascular function and all other
conditions (Myers et al., 2002).However, there also seems to have
further and independent benefits from the practice of physical exercises
and improvement of the aerobic condition as noted by Willians, (2001).
According to Jokinenet al. (2003) the measurement of heart rate reaction
has become a widely used tool for assessing the cardiovascular
autonomic function in various physiological settings. This is because,
regular physical activity programme and good physical fitness are widely
accepted as factors that improve a number of health outcomes and reduce
all-cause mortality (Laukkanenet al. 2001).
Body height and heart
rate of an individual are important variables in the determination of
the health condition of an individual. Certain studies have shown that
height is a factor in overall health while some suggest tallness is
associated with better cardiovascular health and shortness with
longevity (Samaras and Elrick 2002). There are, however, various
diseases and disorders that cause growth abnormalities.
Gender has
been reported to influence autonomic nervous functions in relation to
heart rate reaction in physical activity. In cross-sectional studies,
women have been reported to show higher vagal modulation of heart rate
reaction as compared with men (Ryan et al. 1994). Several mechanisms or
reasons may explain the controversial results or sex differences in
heart rate reaction after aerobic training. This could result from a
complex combination of biochemical, structural, metabolic, humoral and
neural factors (Furlanet al. 1993).
The measurement of human height
and heart rate across various sex groups has often been used as major
component for estimating growth and has proven to be important strategy
in assessing antecedents of diseases such as; risks of
overweight/obesity, diabetes, hypertension, low bone density, CHD, as
well as other human pathologies that could result in morbidity and
death. Hence, this study seeks to examine the sex difference in heart
rate reaction to a specified training programme.
Data on the
relationship between human height and heart beat in Abrakato be
non-available to this study environment. Therefore, there is need to
conduct a research of this kind so as to provide certain anthropometric
information onvariations in heights and heartbeats of male and female
students in the study area.
