AM. Men and women exhibit similar acute hypotensive responses after low, moderate, or high-intensity plyometric training. J Strength Cond Res 30(1): 93-101, 2016-The aim of this study was to compare the acute effects of low-, moderate-, high-, and combined-intensity plyometric training on heart rate (HR), systolic blood pressure (SBP), diastolic blood pressure (DBP), and rate-pressure product (RPP) cardiovascular responses in male and female normotensive subjects. Fifteen (8 women) physically active normotensive subjects participated in this study (age 23.5 6 2.6 years, body mass index 23.8 6 2.3 kg$m 22). Using a randomized crossover design, trials were conducted with rest intervals of at least 48 hours. Each trial comprised 120 jumps, using boxes of 20, 30, and 40 cm for low, moderate, and high intensity, respectively. For combined intensity, the 3 height boxes were combined. Measurements were taken before and after (i.e., every 10 minutes for a period of 90 minutes) each trial. When data responses of men and women were combined, a mean reduction in SBP, DBP, and RPP was observed after all plyometric intensities. No significant differences were observed pre-or postexercise (at any time point) for HR, SBP, DBP, or RPP when low-, moderate-, high-, or combined-intensity trials were compared. No significant differences were observed between male and female subjects, except for a higher SBP reduction in women (212%) compared with men (27%) after high-intensity trial. Although there were minor differences across postexercise time points, collectively, the data demonstrated that all plyometric training intensities can induce an acute postexercise hypotensive effect in young normotensive male and female subjects.

In this study, it is aimed to review the effects of 8 week plyometric exercises on certain physiological parameters and freestyle swimming performance of swimmers of age 10-11 who practice swimming with a licence in city of Van. Study group has been created by 24 male volunteer swimmers who practice swimming with a licence in city of Van. 24 volunteer athletes aged 10-11, who are licenced swimmers for two years and who exercise regularly 5 days a week have been selected for the study. The athletes are randomly divided into experimental and control groups of 12. Throughout the study, in addition to swimming exercises, experimental group is scheduled to 3 days a week plyometric exercise program. Control group is not given any additional exercise except from the swimming exercises. It is seen that the obtained data does not show normal distribution and non-parametric tests of Mann Whitney U and Wilcoxon Test are used for data analysis. Significance level is taken as p<0,05. As per obtained data, pretest and post test data of male swimmers of experimental group show that horizontal and vertical leaps, anaerobic power, 30m sprint, hand grip right and left, 25 and 50 m freestyle swimming parameters showed statistical significant difference; whereas for control group, weight, height, body mass index, anaerobic power and right and left hand grip force parameters showed statistical significant difference (p<0,05). When the pretest and posttests of experimental and control groups are compared, only vertical leap parameter showed significant difference in favor of the experimental group (p<0,05) and for the other parameters, no statistical significant difference is seen (p>0,05). As a result, it is seen that the 8 week plyometric exercise has a significant effect on vertical leap and even though not statistically significant, it is pondered that it has a positive effect on freestyle swimming duration of experimental group, compared to that of control group.

The purpose of this study was to compare the effects of high, moderate and low intensity plyometric exercise on the post-exercise systolic and diastolic blood pressure and heart rate responses. Ten healthy normotensive men (age, 21.1±0.9 years; height, 175.8±6 cm; and body mass, 69.1±13.6 kg) volunteered to participate in this study and were evaluated for three non-consecutive days in depth jump exercise from 20-cm box (low intensity [LI]), 40-cm box (moderate intensity [MI]) and 60-cm box (high intensity [HI]) for 5 sets of 20 repetitions. After each exercise session, systolic blood pressure (SBP), diastolic blood pressure (DBP) and heart rate (HR) were measured every 10 min for a period of 90 min. No significant differences were observed among post-exercise SBP, DBP and HR when the protocols (LI, MI and HI) were compared. The LI and HI protocols showed greater reduction in SBP at 40(th)-70(th) min of post-exercise (~9%), whereas the LI and MI protocols indicated greater reduction ...
EFFECT OF PLYOMETRIC TRAINING ON SELECTED PHYSIOLOGICAL PARAMETERSAMONG HANDBALL PLAYERS
Plyometric training is most favoured physical conditioning among the sports persons to enhance the explosive strength, speed and power. Studies says that hypertension can be most common risk factor for cardiovascular diseases among elite players. So therefore, it is important to do regular physical activity to maintain the normal blood pressure. This study intensively checks out the effect of plyometric training on selected physiological parameters among male handball players. To accomplish the result of the study thirty male student from Alagappa University College of Physical Education were selected as a subject. The subjects age ranges from 18 to 25 years. The selected subjects were further categorized into two uniform group of fifteen each, namely Plyometric training group (Experiment group) and Control group. The experimental group were engaged in plyometric training at morning time for eleven weeks, 3 days per week for 1hours (Monday, Wednesday and Friday). On the other hand, control group preserve their daily routine activities and no such special training was given to them. Every single subject of two groups were tested on selected criterion variables namely systolic blood pressure (SBP) and diastolic blood pressure (DBP) which was measured by sphygmomanometer and breath holding time was taken by nose clip method. The data collected from the subjects was statistically analyzed with 't' test to find out significant improvement if any at 0.05 level of confidence which was observe as a relevant. The outcome of thisstudy manifest that there was significant difference among Plyometric training group and control group. Along with, Plyometric training group proclaim significant improvement on Systolic blood pressure, Diastolic blood pressure and Breathe holding time.

To determine the time course of performance responses after an acute bout of plyometric exercise combined with high and low intensity weight training, a 3-group (including a control group), repeated-measures design was employed. Changes in performance were monitored through jumping ability by measuring countermovement and squat jumping, and strength performance assessment through isometric and isokinetic testing of knee extensors (at two different velocities). Participants in both experimental groups performed a plyometric protocol consisting of 50 jumps over 50 cm hurdles and 50 drop jumps from a 50 cm plyometric box. Additionally, each group performed two basic weight exercises consisting of leg presses and leg extensions at 90-95% of maximum muscle strength for the high intensity group and 60% of maximum muscle strength for the low intensity group. The results of the study suggest that an acute bout of intense plyometric exercise combined with weight exercise induces time-dependent changes in performance, which are also dependent on the nature of exercise protocol and testing procedures. In conclusion, acute plyometric exercise with weight exercise may induce a substantial decline in jumping performance for as long as 72 hours but not in other forms of muscle strength.

Brown, GA, Ray, MW, Abbey, BM, Shaw, BS, and Shaw, I. Oxygen consumption, heart rate, and blood lactate responses to an acute bout of plyometric depth jumps in college-aged men and women. J Strength Cond Res 24(9): 2475-2482, 2010-Although plyometrics are widely used in athletic conditioning, the acute physiologic responses to plyometrics have not been described. The purpose of this study was to investigate the oxygen consumption, heart rate, and blood lactate responses to a single session of plyometric depth jumps. Twenty recreationally trained college-aged subjects (10 men, 10 women) participated in a single session of 8 sets of 10 box depth jumps from a height of 0.8 m with 3 minutes of passive recovery between each set. Plyometric depth jumping elicited 82.5 6 3.1% and 77.8 6 3.1% of the measured maximal oxygen consumption ( _ VO 2 max) for women and men, respectively, with no difference in oxygen consumption in ml/kg/min or percent _ VO 2 max between sexes or sets. Heart rate significantly increased (p , 0.05) from 68.1 6 2.9 beatsÁmin 21 at rest to 169.6 6 1.2 beatsÁmin 21 during depth jumping. Sets 5 to 8 elicited a higher (p , 0.05) heart rate (173.3 6 1.3 beatsÁmin 21 ) than sets 1 to 4 (164.6 6 1.8 beatsÁmin 21 ). Women exhibited a higher heart rate (p , 0.05) during sets 1 and 2 (169.9 6 2.8 beatsÁmin 21 ) than men (150.7 6 4.4 beatsÁmin 21 ). The blood lactate concentrations were significantly (p , 0.05) increased above resting throughout all sets (1.0 6 0.2 mmolÁL 21 compared with 2.9 6 0.1 mmolÁL 21 ), with no differences between sexes or sets. Plyometric depth jumping significantly increased oxygen consumption, heart rate, and blood lactate in both men and women, but no significant difference was found between the sexes. Plyometric depth jumping from a height of 0.8 m has similar energy system requirements to what Wilmore and Costill termed ''Aerobic Power'' training, which should enhance _ VO 2 max, lactate tolerance, oxidative enzymes, and lactate threshold.
