"Muscle thickness" refers to the size or how big and thick your muscles are.
Full definition
At the end of a training session, getting stronger is the best way to experience muscle growth and see the
increased muscle thickness.
At baseline, week four, and week eight, participants were measured
for muscle thickness, body composition, bench press and leg press strength.
Pea protein can promote
muscle thickness gains when taken in conjunction with a resistance training program (9).
While x-rays are not useful to measure the
heart muscle thickness, they are used to rule out lung congestion and solid masses (cancer).
BetaTOR supplementation resulted in a 200 % increase in
muscle thickness compared with placebo supplementation over the 12 - week study.
The central region of the gastrocnemius displayed the
greatest muscle thickness, while the distal region displayed the lowest.
A number of studies have described the
trapezius muscle thickness including differences between the three regions and areas closer to its origin or insertion.
researchers found that pea protein was able to help athletes increase
muscle thickness just as effectively as dairy - based proteins.
The people who responded to spinal manipulation reported less pain right away and showed improvement in
back muscle thickness, disc diffusion and spinal stiffness.
Whether you're a competitive athlete who can't be satisfied until there's no gas left in the tank or just an enthusiastic bodybuilder who wants to get the biggest bang for his buck, finishers can help you push through your pain barriers and earn some
extra muscle thickness.
By the end of the study, the training group had lowered their body fat count by 4.2 % (vs. 0 % in the control group), increased lean body mass by 2.7 % (vs. 2.0 % in control), increased
thigh muscle thickness by 3.2 % (vs. 0 %), increased knee extension strength by 16 % (vs. 8 %), and increased jump height by 3.4 % (vs. 1.8 % in the control group).
Additionally, based on strength and hypertrophy (
i.e. muscle thickness and volume) effect - size data, the research suggests that exercises be ordered based on priority of importance as dictated by the training goal of a programme, irrespective of whether the exercise involves a relatively large or small muscle group.
Ogasawara et al. (2012) reported
similar muscle thickness in a comparable group of males (aged 25 years), reporting measures of 25.1 mm.
Indeed, Ogasawara et al. (2012) showed that pectoralis
major muscle thickness and wide grip bench press 1RM increased in tandem over a 24 - week resistance training program, as can be seen in the chart below.
Average
muscle thickness of the internal oblique ranged between 8.2 — 12.7 mm in males and 7.4 — 9.6 mm in females.
HMB free acid supplemented subjects had greater strength gains, increased Wingate power, and increased
muscle thickness compared with the placebo supplemented subjects.
At baseline (week 0), midway (week 4), and end (week 8) participants were measured
for muscle thickness, body composition, bench press and leg press strength.
In a study published in the Journal of the International Society of Sports Nutrition, researchers found that pea protein was able to help athletes increase
muscle thickness just as effectively as dairy - based proteins.
Hill et al didn't
measure muscle thickness, but it wouldn't surprise me if at 20 days the guinea pigs on their way to an early death had the thickest and most massive quadriceps.
Subjects taking the nutrient had improvement in
muscle thickness to help individuals gain greater muscle strength.
In 2015, the Journal of the International Society of Sports Nutrition found that pea proteins can be just as efficient as whey, both producing similar gains in
muscle thickness and strength when used after resistance training.
The upper and middle fibers display greater PCSA and
muscle thickness, respectively, compared with the lower fibers.
Narici et al. (1996) reported that
the muscle thickness of the medial gastrocnemius muscle ranged between 16.9 — 18.6 mm, depending on the region of the muscle being measured.
When the thickest part of the muscle belly was measured,
the muscle thickness was much greater in the middle fibers (15.4 mm) compared with the lower fibers (6.8 mm), respectively.
The upper and middle fibers display greater physiological cross-sectional area and
muscle thickness, respectively, compared with the lower fibers.
The medial gastrocnemius is larger and displays a greater
muscle thickness than the lateral gastrocnemius, while the soleus displays the smallest muscle thickness.
In contrast, O'Sullivan et al. (2009) measured the trapezius fascicles using magnetic resonance imaging (MRI) and found that
the muscle thickness ranged between 3.8 — 15.4 mm depending on the muscle region and the part of the muscle being measured.
Few studies have investigated
the muscle thickness of the individual calf muscles.
Finally, Maganaris et al. (1998) also assessed
the muscle thickness of the soleus and reported that it ranged between 13.9 — 16.0 mm.
Maganaris et al. (1998) also reported that
the muscle thickness of the lateral gastrocnemius similarly ranged between 15.6 — 16.0 mm.
Therefore, it appears that the medial gastrocnemius displays a larger
muscle thickness compared to the lateral gastrocnemius, while the soleus appears to display the smallest muscle thickness.
In agreement, Maganaris et al. (1998) reported that
the muscle thickness of the medial gastrocnemius measured 16.6 — 17.1 mm.
The study also showed that similar gains were made in terms of
muscle thickness and strength in the whey group and the pea group.
If the cross-sectional area of a muscle is proportional to the square of
muscle thickness, then we can get a measure of strength per unit cross-section by taking the ratio of leg press 1RM to the square of rectus femoris thickness.
Very limited data is available on
the muscle thickness of the biceps muscle.
Miyatani et al. (2004) investigated the reliability of
muscle thickness between magnetic resonance imaging (MRI) scans and ultrasound imaging in males aged 23 - 40 years.
Muscle thickness is another measure of muscle hypertrophy.
Little data exists on
the muscle thickness of the triceps.
Thus, the data indicates that
the muscle thickness of the triceps muscle varies with age and gender but is around 30 — 35 mm.
Overall,
the muscle thickness of the abdominals is generally greater in males compared to females and the internal oblique displays the largest difference between genders.
